Technical Specifications forInstallation of DG Set Mechanica/Electrical



TECHNICAL SPECIFICATIONS FOR

INSTALLATION OF DG SET (MECHANICAL)1. UNLOADING OF MATERIAL (Lifting, Leading & Installation)

We have to use proper tools, adequate manpower & arrangements to unload the materialdepending upon its size and weight to avoid damages.

For Unloading of engine, alternator and auxiliaries etc., should use hooks which are provided onit for handling with crane otherwise we have to use jacks & sleepers with wrench and wire rope.

If crane is used to unload, the capacity of crane should be twice the weight of material

Crane documents should be verified before allowing to work as per RTO.

Slings of crane should be lubricated and joints of the sling should be examined for perfect fitmentwith clamping.

While unloading the crane should be supported by jacks on both ends and tyres should be lockedat both end with some media like sleepers to avoid jerking while unloading.

NOTE : Collect a catalogue from crane manufacturer for more informations.

No material shall be slinged with any components of machineries like motors, pumps, pipes

base frame etc.

No body should step on the components to do any work while unloading, leading or at the time ofinstallation.

For each sq. mtrs. 4 persons are required for handling of material to avoid any damage tomaterial, what ever may be its weight.

All glass parts, instrumentation items, pressure gauges etc. should be handled with care andprecautions to avoid damage, no jerks & drops.

While handling the material top side mark should always be maintained at the top.

NOTE : Enquire the capacity of winch, pulleys used for leading and lifting of materials dependingupon the weight.

2. CHECKING OF LAYOUT.

Civil layout made by customer should be collected from customer and compared with KOELlayout w.r.t. dimensions, if any variation is noticed enquire with Customer.

Locate the direction of power house & co-relate with drawing, than locate foundation blocks ofengine and its auxiliaries as per drawing.

2.1


7/94





3. CHECKING OF MATERIAL

Check the material as per packing sheets and also cross check with application code, if there isany shortage / damage, intimate to KOEL Ofiice immediately.

Examine the material for its condition frequently during the course of commissioning.

Inform shortage of material, if any in advance.

Make a chart for weekly material consumption and cross check the plan with every day actualconsumption.

Correctness of material should be checked for weekly plan.

4. PIPING NORMS

Each pipe should clearly shows the direction of flow of liquids with arrows.

If any doubt in pipe size of circuit, clarify with KOEL AE.

5. PIPING SUPPORTS

The pipe must be supported on both side of bend joints, flange joints and Auxiliaries ends within afeet.

In every 4 meters of pipeline there should be a support.

For supports use 50 x 50 x 5 angles or 100 x 50 x 5 C Channel. Use U clamps, washer and nuts forclamping the pipes with angle & channel.

All supports must be painted by BLACK paint, before clamping the pipes.

For clamps of pipes to supports, all holes on supports should be drilled and shall not be done bygas cutting.

All Supports should be horizontal.

At every 5 mtrs. length there must be flange connection except for Fuel.

All flange of pipeline should be minimum 100 mm above the trench floor and supports should be300 mm. above floor level of trench.

The vertical gaps between pipe line supports in double tier should be maintained around 300 mm.

Lower support should be both side welded in trench and above that, only one support of cantile-ver type and only one side of trench with a gap of 400 mm. from opposite side of trench.

NOTE : Ensure that the trenches are water proof before laying pipelines.

2.2

6. WELDING

The angle between the two pieces of pipes to be welded should be chamfered.

The distance between two pipes should be half of the thickness of the pipe, which are to bewelded together.

Before starting the welding clean the edge to be welded thoroughly and make sure edges are dry.use proper flux for proper welding with correct grade of welding rods.

Properly chamfer the edges to be welded.

Remove distance piece used to maintain gap between pipes.

Root weld and brush it by wire brush before doing 2nd round i.e. there is no any red beed.

Capacity of welding machine should be as per the welding rod requirement. Keep all welding

rods packets in a dry container.

If welding rods are wet they should be kept in a oven for drying before use.Do not use sub-standard, damaged or cracked welding rods.

Standard welding rods requirement

Air 45 bar

(The Hydro test should be carried out by pump which is to be arranged by contractor)

NOTE : The specifications of hand pump required for Hydro test are to be confirmed.

Before Hydro test all pipes should be thoroughly cleaned with wire brush chipping at flange end

and by water flushing.Any leakage found in the Hydro test should be rectified and pipe should be retested for leakage.

Put a air vent at highest point of pipe line while doing Hydrotest which should withstand therequired pressure.

After Hydro test no work should be done on the pipe line like gas cutting, drilling, welding etc.

The pressure should hold, at least for one hour without any leakage.

For exhaust and air intake ducting there is no Hydro test.

Chapter 5 - PROCEDUREGrouting Procedure



Document no.-27.400.85.0.00

TECHNICAL NOTE

GROUTING PROCEDURE

INTRODUCTION

During installation of DG set on the foundation block, grouting is carried out in order.a) To minimize heat build up on foundation block.b) To assure precise and unsurpassed contact with baseframe.c) To provide a high coefficient of friction to help maintain DG set alignment which

further reduces possible bearing or crank shaft alternator rotor damage.

Generally powdered FOSROCK GP2 is used as grouting compound which is mixed withwater along with coarse aggregates or pea gravel of size 6sq.mm. down to obtain free

flowing grout. ** Aggregates to be used only for pockets.

1) PREPARATION OF GROUT

In order to obtain optimum physical properties with grouts, precise mixing and curing ofgrout is necessary.

A) MATERIAL AND EQUIPMENT REQUIRED FOR PREPARATION OF GROUT

- FOSROCK GP2 of sufficient quantity.- Crushed aggregates or pea gravels of size 6 sq.mm. down to sufficient quantity.- A 220 lits. drum for stocking water - 4 Nos.- Buckets to carry mixed grout - 6 Nos.

- Concrete mixer - tilting drum type - 2 Nos.- A water can measuring 4.5 lits. capacity.- A pan with dry FOSROCK GP2 in case of leaks.- Water bath curing compound - 2 Nos.- Hammer, Chisels, nails etc.- Wire Brush.- Sufficient length of MS plates.- Masonry tools like pan, trowel etc.

B) MIXING OF GROUT- The quantity of grout required is estimated by using the following thumb rule.

Weight of FOSROCK GP2 required = 2 x vol. of grouting space.- Place about 80% of the water required per batch inside the mixer.- Add bag by bag FOSROCK GP2 with mixer running.- Add balance about 20% water.- Add the crushed aggregates or pea gravel about 50% by wt. of FOSROCK GP2.- Mix for 5 minutes.- Unload into buckets for transporting and placing.

B.1) PRECAUTIONARY MEASURES TO BE TAKEN DURING MIXING- Do not mix anything else like sand, cement etc. to the grout.- Do not pour more that 4.3 liters of water per bag of FOSROCK GP2 for grouting pockets

and 4.5 liters. for plain grouting.- Mixed grout should be consumed within 20 minutes after mixing.

5.1


22/94




- If the ambient temperature is very high (above 40 deg.C) and humidity also is low, thegrout tends to lose moisture fast and thus fluidity is reduced. Under such circumstances,

mixed grout may have to be consumed immediately after mixing.

B.2) CHECKS TO BE FOLLOWED BEFORE MIXING- Ensure the FOSROCK GP2 used is well protected from moisture and no damages have

occurred.- No Vibrators are used as a means of mixing.

2) PLACING OVER OF GROUT

C) CHECKS TO BE FOLLOWED BEFORE GROUTING

- The top surface of foundation block is plane and rigid.- The top surface of foundation and bottom surface of baseframe should be free from oil,

grease and debris.The foundation block is soaked with water for about 24 hours.

- Ensure lowering of baseframe and anchor bolts in position.- Sole plates (Reqd. if any in relation to alignment) are well levelled.- Shuttering around the sole plates with MS angle or wooden block is done.

D) GROUTING PROCEDURE- Grout the sole plates individually upto half their thicknesses.- Use mixed grout for the space in between sole plates and space around the sole plates.- Continue to grout bay after bay in both the sole plates.

E) CHECKS TO BE FOLLOWED DURING GROUTING

- Pouring of grout should be continuous and from one side to avoid voids.- Check for leaks. The leakages can be avoided by applying dry FOSROCK GP2.

F) CURING OF GROUT- After 4 hours of grouting the grout becomes hard so water curing is carried out. Curing

period should be minimum 6 d

PREPARATION OF FOUNDATION BLOCK

z A surcharge of 15 mm concrete is provided on the top surface of foundation block.

z The block surface shall be gently chipped off. There should not be any peak exceeding

10 mm. The top surface of block shall be perfectly cleaned after chipping.

z Mark the location of chokes (MS Block) on the foundation block just below the jacking

bolt location.

z The bearing area near the chokes to be flattened to the size 250 mm (L) x 150 mm (w).

Surface shall be cleaned again.

z Position the chokes such that length of each block gets equally divided at the centre of

jacking hole. Chokes should be longitudinally parallel to the foundation block.

z The foundation block and pockets shall be soaked with water for about 24 hrs.

z Remove all remaining water from the pockets.

z Place all the foundation bolts in the pockets.

z Place the baseframe on minimum 200 mm height wooden sleepers and align all base

frame mounting holes with pocket centres.

z Clean the alternator mounting pads on the baseframe. Place the alternator on the base

frame. Loosely connect the mounting bolts with alternator.

z Clean baseplate bottom so that it is free from oil, debris etc. Insert foundation bolts from

bottom in the baseframe. Assemble nut and washer with foundation bolt. Ensure that boltprojection is about 20 mm above nut top surface.

z Ensure all bolts are laying straight in the pockets. The foundation bolt should not remain

inclined in the pocket.

z Lower the baseframe (with engine mounted on it) slowly on the choke plates and ensure

that it rests firmly on all the chokes. While lowering the base frame make sure thatadjacent jacking screws are equally loaded and foundation bolts are in perfect position.

z Carry out the leveling of baseframe with water level tube and level bottle. The baseframe

should be leveled within 2 mm of water level.

Note : Engine is mounted on the baseframe.

PARTIAL GROUTING OF FOUNDATION BOLT

z Refer specification No. 27.400.85.0.00 for preparation of grouting material and

procedure.

zFill 3/4th portion of pockets by slowly pouring the mixed grout. Ensure that there is no airpocket or cavity (voids) in the pocket after poring of grout.

z After 4 hrs. of grouting the grout becomes hard, water curing is therefore necessary for

minimum 6 days.

z Carry out leveling checks once again before final grouting.

z Carry out shuttering around the baseframe with MS angle or wooden plate.

z Fill remaining 1/4th portion of the pocket with mixed grout.

z Use pure GP2 cement for grouting the space between bottom of baseplate and

foundation block top surface. Grouting will be done such that GP2 cement is filledsurrounding the baseplate and foundation block top surface. About 150 mm wide layersurrounding the baseplate and 3/4th thickness of bottom plate of baseplate in height will

5.3


24/94




be filled up with GP2 cement. Grouting should be continuous and from one side to avoidvoids.

z Check for leaks. The leakage can be avoided by applying dry FOSROCK GP2.

z After 4 hrs of grouting the grout becomes hard therefore water curing has to be carried

out. Curing period should be minimum 6 days.

z During curing period, meanwhile remove shuttering and carry out cementing of portion

between baseplate and edge of foundation block on all four sides. Provide suitable slopetowards the edge of foundation block.

TORQUING OF FOUNDATION BOLTS

z After 6 days of grouting carry out torquing as per sequence given below.

1) First apply 10 kgm torque on centrally located foundation bolt on both sides.

2) Continue applying torque 10 kgm on foundation bolts starting from centrally located bolt

towards engine and alternator and simultaneously on both sides.3) Repeat procedure by increasing torque value by 10 kgm in each step till final torquing of

95 kgm is achieved.

RELATIVE POSITION OF THE SHAFTS IN THE HORIZONTAL PLANE

The measurements show that :

A axis is more at right than B one by = 9

in the plane of dial gauge C1.

B axis is more at right than A one by = 47

in the plane of dial gauge C2

Then the relative position of the shafts is as follows :

The experience shows that some erectors prefer to realize an intermediary sketch giving the

relative position of the traces of the axis A and B in the planes C1 and C2 before carrying out the

representation of the axis in the vertical plane and the horizontal plane.

With this operation the operators can probably better figure out the axis in the space, this inter-

INSTALLATION & COMMISSIONING MANUALKirloskar Oil Engines Ltd.Large Engines Division

CHEMICAL CLEANING PROCEDURE FOR PIPES

[Chemical Cleaning of the associated piping of DG set subsystem ( Material of constructioncarbon steel - seamless Tube ASTM A 106)]

1. LOOP FORMATION

The various pipes are joined together by means of mating flanges and flexible hoses and formedinto a closed loop system alongwith the chemical circulation pump and tank.

2. PREFLUSH

The system is filled with water and leak tested, it is then continuously flushed with water into the

drain gutter. All high points if any are to be vented regularly till system is completely filled.

3. DEGREASING

The objective of degreasing is to remove all the dirt, loose rust and mill scale so as to provide anactive surface for acidic solvent treatment.

The degreasing solvent to be used is proprietary formulation of an Alkali alongwith a Non lonicWetting Agent.

The degreasing is to be carried out for a period of 2 hrs. at a temp. of 40 Deg. C and flow velocityof 0.2 m/s.

4. FLUSHINGUse service water to flush the system till pH is neutral.

5. ACIDIC SOLVENT TREATMENT

The objective of acidic solvent treatment HCL 50% (strength 30%) + 50% water is to remove allthe rust, mill scale, welding slag and other oxide deposits. The circulation is to be carried out fora period 1-2 hrs. with help of acid circulation pump at flow velocity of 0.3 m/s.During the circula-tion hammer the pipe loop at regular interval so that welding slag,mill scale get removed.

6. DRAINING & FLUSHING

The acidic solvent is drained and the system is flushed completely till pH is neutral.

7. ORGANIC ACID RINSE

The step involves the circulation of an ammoniated organic acid (10% Caustic Soda + Water)having an alkaline pH to remove all residual matter and neutralize the acid solvent.

The circulation of this is to be carried out for a period for 1 hr. at ambient temperature.

Chapter 8 - KOELS RECOMMENDATIONSNote on Water Quality & Recommendation



QUALITY OF WATER REQUIRED TO PA6 ENGINES

The raw water available for a cooling tower, could contain following characteristics :

Hardness < 2500 mg / lit

Alkalimetric Content (TAC) < 400 ppm

Silicon < 100 mg / lit

Suspended Matter < 20 mg / lit

Chlorine < 300 mg / lit

Sulphates < 600 ppm

Ca Concentration Product < 15000 (F)2

Although chemicals are available to condition such water quality, our experience in the pasthave shown that the problems occurs due to scaling / fouling and corrosion in the raw watersystem These problems occurred either due to incorrect treatment, or bad monitoring. Basedon past experience, KOEL essentially recommends softened water for use on raw watercircuit for PA6 engines, with cooling tower applications.

The softened water will have the following characteristics :

pH > 6

Total hardness < 5 ppm

Alkalimetic content (TAC) < 400 ppm

Salinity strength < 300 ppm

Suspended Matters < 20 ppm

Please note that it is impossible to one treatment procedure for water at all sites. Werecommend a pre-survey by water treatment experts from M/s Nalco or M/s Ion Exchange fortheir recommendations or economical conditioning of water.

Si suspended matter concentration, Ca concentration Chlorides + Sulphates will be decidedTOS etc. case to case basis on joint consultation with engine manufacturer & water treatmentexperts.

A comprehensive TIN will be prepared on the above subject.

Please note, the softened water outlet must be checked periodically and regularly to ascertainthe correctness of regeneration frequency.

Use of Nalco / Ion Exchange chemicals must not be avoided to use of softener.

H. T. Water :

KOEL essentially recommends the use of DM water for H.T. water circuit with Nalco /Ion Exchange chemicals.

RE / RAVI / KH -1 / 5516

Date : 05/06/1999

8.1


29/94




Please note DM water being corrosive in nature must not be used without chemicals in H.T.water circuit as this will cause corrosion

Before commissioning of DG set, the DM water with chemicals must be kept available soas to ensure their use of correct water quality and chemicals from first instance itself.

Also ensure availability of softened water for L.T. Circuit and suitable chemicals during startof set. Ensure the availability of the expert from the chemical supplying company (Nalco /Ion Exchange) to stabilize the water chemistry and recommend correct final dosage ofchemicals.

Maintain a log book of essential water parameters as suggested by the expert on the site.

LT , HT COOLING WATERUnsuitable water, results in scaling, pitting or corrosion. Use of very soft water should notdispense with water treatment, since water absorbs Carbon - di - Oxide which renders itcorrosive.

LT WATER SYSTEM :

LT WATER system can either be.

1) Closed

2) Half Open (for Stationary Plants)

3) Open : With waste water and sea water. Necessary steps to be taken to avoidcorrosion, Scaling & to eliminate seaweeds & bacteria.

In open system, precautions to be taken are as follows:

1) A suction strainer should be provided and maintained in clean condition.

2) Piping should be reduced so that flow rate should be maintained to avoidtemperature raise above 40 oC in order to avoid salt deposition.

3) For application with sea water, pipes, Lub oil cooler and charge air cooler to bewaterproof ex. Bronze, Cupro-Nickel.

Temperature deviation between system inlet and outlet should range from 10 to 12oC at fullload.

REQUIRED WATER PROPERTIES :

1) Hardness : Total hydrodynamic hardness should be minimum. Water can besoftened by using Soda.

2) pH should be more than 6

3) Chlorine ion content should be minimum (below 100 mg/ lit)

4) Salinity should be less than 200 mg / lit

5) Water should be clean at filling. If required can be cleaned by adding chemicals,further rinsing is necessary since these chemicals are acid.

NECESSITY OF WATER TREATMENT1) To avoid chemical & electrochemical corrosion from different metals which requires

basicity (pH) level to be maintained between 7.5 to 9.

2) To avoid scale, liable to reduce wall heat conductivity.

TYPES OF TREATMENT

1) CHROMATE:

Sodium & Potassium Chromate provides protection on Iron. Their efficiency of antiscalingprotection can be increased by addition of organic compounds. For Aluminium and coppersince, it is not compatible, it can be gained by adding Borate compound.

TIN/COOL/VMK/001-00

Date : 14/04/1998

31/94




When Chromate drops below 0.5 gm/lit, it becomes dangerous. They are then capable oforiginating corrosive reaction, chromate level recommended 2.5 to 3 gm/lit. Chromate doesnot deteriorate with time.

2) BORATE - NITRITE:

Mixture of sodium Borates & Nitrites with addition of organic compounds ensure efficientantiscaling action and corrosion resistance for ferrous material. But Nitrites in alone attackon welding therefore other components like borate - benzoates are added. 3 to 5 gm / litnitric contain is recommended. Nitrite are toxic from absorption of 4 gm of pure nitrite salts.

Requirements of Additives :

1) It must prevent corrosion

2) It must prevent precipitation of scaling salts.

3) It should be soluble in water4) It must be compatible with anti - freeze.

5) It must have suitable pH range . (Stabilising 7.5 to 9)

Chapter 9- KOELS RECOMMENDATIONSNote on Lub Oil Quality & Recommendation



LUBRICATING OIL FOR PA-6 ENGINES

High speed diesel engine of our range needs specially tailored lub oil, catering to following

conditions:

1) High firing pressure

2) Mean Piston Speed

3) High combustion temperature

The above factors results in high stress on mechanical components and lubricating oil

SEMT Pielstick has an elaborate approval procedure of lubricating oil for their engines. After

through tests on chemical and physical characteristics of lubricating oil. It is subjected to rigerous

on field trials, before a certain lubricating oil brand is approved for a specific engine series.

IMPORTANT CHARACTERISTICS OF LUBRICATING OIL :

A) VISCOSITY :

To avoid metal to metal contact, it is mandatory to have stable and sufficient thick oil film

between cylinder liner and piston ring. Oil from this region is high temperature thereby lower

viscosity than when entering in the engine. The viscosity index expressing the temperature

dependent of the viscosity is of importance to protect engine components.

Lubricating oil viscosity has been chosen as being defined by SAE 40 grade that is between 12.5

to 16.3 cSt at 100 Deg C. In this range, correct lubricating oil film and flow will be made through

engine.

If the viscosity changes, film thickness and flow will trend towards the values which can be

dangerous to the engine.

CAUSE OF DROP IN VISCOSITY :

a) Diesel dilution coming from pump leakage (HSD)

b) Unburnt diesel in fuel chamber.

c) Leakages through injection pump.

CAUSE OF RAISE IN VISCOSITY :

a) Oxidation,

b) Presence of insolubles

c) Raw Fuel Dilution

Alarm Limit : 2/3 SAE grade Variation (18%)

Rejection Limit : One grade of SAE (25% variation of viscosity)

B) TOTAL BASE NO (TBN) :

This value defines the resistance value of lub oil against the corrosion (Mainly sulphuric, generated

from Sulphur in Fuel)

9.1

TIN No. : TIN/LO/VMK/001/00

Date : 19/06/1999


36/943 - 2




Other than Sulphur, Other engine running condition have an effect on this value. A too cold

water will lead to temperature on liner walls lower than dew point of Sulphuric Acid.

CAUSE OF DROP IN TBN1) High Sulphur Content

2) Bad Adjustment of HT water Circuit

3) Precipitation of additives due to water presence.

LIMITS FOR TBN FOR LUB OIL :

Fuel Gas Oil Gas Oil Distillates Interediates HFO

% Sulphur < 0.1 < 1 < 1.8 0.3 - 1.8 1.8 - 3.0 3 - 4 < 5

Mn TBN 5 10 16 16 20 20 25 - 28

To keep cold corrosion rate low, neutralisation capacity of lub oil must be sufficiently high. Therefore

TBN 40 oil is recommended for HFO Operation.

C) WATER CONTENT :

Presence of water in lub oil is the risk of major break down of engine. The water elimination

will be made by centrifuges adjusted as purifier.

Normal water content : 0.1 %

Alarm Limit : 0.2 %

Rejection Limit : 0.5 %

In case of excessive wear, the water content, TBN & lub oil additives must be controlled. (Lub

Oil additives trend is to react with water and disappear with it)

CAUSES OF WATER CONTENT IN LUB OIL :

a) Condensation of crankcase wall in humid and tropical zones.

b) Engine Leakages

c) Leakages in lub oil cooler

d) Bad running of centrifuge.

D) FLASH POINT :It is the temperature at which mist and product are ignited with a flame- hot point (In

case of engines) like cylinder and crankshaft or by flame generated by blowby owing to bad

tightness of rings.

Flash point for new oil : 235 to 240 Deg C

Alarm Level : 50 Deg C less than new oils flash point (Higher than 190 Deg C)

Rejection Limit : 150 Deg C risk of self ignition and bursting of crankcase.

9.2


37/943 - 3




E) DETERGENCY / DISPERSANCY :

Oil has to keep clean the liners, pistons, piston Rings, and ring grooves from thecombustion products, This property is called as high temperature detergency.

After lubricating the piston and liner, oil returns to sump during which it cleans crankcase walls

connecting rods, Crankshafts. This effect is known as low temperature detergency.

DISPERSANCY : Ability of oil to maintain in suspension all particles and unburnt components

picked by oil in piston, liners etc. All the impurities must be transported to the purifier where

most are removed. Dispersancy determined by visual inspection and automatic analysis of a

spot.

These values allow to define if the lub oil is still capable to clean and maintain the material in

suspension.

F) ANTIWEAR AND EXTREME PRESSURE:

Whenever the oil film gets interrupted from or in insufficient quantity, the tribological

characteristics have to be supported by antiwear and extreme pressure additives to reduce

abrasive and adhesive wear.

G) THERMAL STABILITY :

Oil is exposed to long period of high temperature. Adequate thermal stability is therefore

vital.

H) OXIDATION STABILITY :

Oxidation stability is required to prevent oxidation of oil due to high temperature and

oxygen surplus in blow by gases and trapped air.

I) LUBRICITY :

Lubricant must be capable of covering surfaces to be protected. Therefore good

spreadablity and reliability cohesion to the mettalic surfaces are required.

J) ALKALINITY :

The property permits the oil to react against corrosive wear by neutralising acidic

combustion products from fuel sulphur.

K) COMPATIBILITY WITH HEAVY FUEL :

The lubricating oil and fuel should be compatible at prevailing temperature. Otherwise

plunger sticking by deposit formation in fuel pump initiated by asphanates drop out from fuel

may take place.

9.3


38/943 - 4




L ) ANTIFOAMING :Oil circulation in engine is continuous. During the circulation, air gets mixed with oil

intensively. Antifoaming capacity of lubricating oil should be high otherwise which is dangerous

for bearing.

FUNCTION OF LUBRICATING OIL.

1) Lubrication

2) Cooling

3) Anticorrosion

4) Antiwear

LUBRICATION SYSTEMI) BEARING LUBRICATION

Between crankshaft journal and bearing there must be an oil film of a defined thickness.

By considering engine characteristics and temperature requirements, viscosity grade should

be selected and specified viscosity grade shall be used.

The oil is circulated in crankshaft to reach big end bearing of connecting rod. Here the

oil film has to provide an oil film to resist the impact resulting from combustion pressure on

piston head.

The oil passes towards small end (through connecting rod holes) bearing of gudgeon

pin where again oil film is required. A important task of lubricating oil is to cool the bearings

(removing frictional heat)

II) PISTON COOLING

After gudgeon pin, oil enters in the interior as a coolant medium (cooling the piston

head). For this oil must have good resistance against deterioration at high temperature which

is known as Oxidation Stability.

III) OUR LUB OIL CONSUMPTION :

Recommended lub oil consumption is 0.8 to 1.2 gm / kwh. optimisation of Piston ring

set, piston clearance, liner temperature and its ability to retain the shape and liner surface are

prerequisites of lub oil consumption, this rate includes losses in separators / filters.

Oil change is required when lub oil consumption gets decreased. reduced oil

consumption results in stress on oil, as oil volume will be replenished to lesser degrees by

fresh oil. Therefore will require frequent oil changes. It could also indicate a trend of external

contamination etc. (Fuel dilution into lub oil or water contamination in lub oil through improper

STARTING INTERLOCK

Manual mode

Fuel Control Handle should be unlocked.Turning Gear to be disengaged.Level of Water Expansion Tank should be more than low level.

Starting Air Pressure should be more than 16 bar.No Safety Stop should be operated.DG Breaker should be in off condition.Lube Oil Priming pressure should be more than 0.5 bar.

Engine should not be in running condition.

Auto mode

HT Water Engine Inlet Temp. should be more than 40 Deg.

PRE HEATING AND PRIMING MOUDLE

Ability of an engine to take the load rapidly after a standstill period depends essentially on theambient conditions.More precisely on HT water and Lube oil temperature at the time of starting.DG set is equipped with Pre Heating and Priming module, which maintains a reduced flow of

HT water and lube oil in the engine.

This equipment allows maintaining water temp. between 40 to 50 deg. in the cylinders andcylinder heads, decreasing the lube oil viscosity and thus avoid the over pressure on starting,ensures an adequate lubrication of all the moving components.

Power supply to this module is fed from alternate supply source.

MODE OF OPERATION

There are three modes to start the DG set.

Auto mode :

Start of the engine shall be through AMF operation.

Engine will be start after checking the following condition.Under voltage relays on GCP/Customer panel senses the bus supply.In AMF mode these Under voltage relays will give command for starting the DG set


42/94





MANUAL MODE-

In Manual mode Starting of Engine, Closingof the DG Breaker manual.

Closing of breaker may be Either dead bus orlive bus.

In case of live bus of closing DG Breaker can

be momentary paralleled With either of normalincomer.In this Engine starting can only be done After

checking all necessary process Permissive.

TEST MODE-

In Test mode operation is similar to AUTOoperationGrid supply fail signal is given to PLC by simulation.

ALTERNATORBasic Operating Principle

Exciting current Ie(dc current from AVR)flows through exciter Stator.

It induces emf in exciter rotor(3 Ph).Then It is rectified by rotating diode and field current flowsthrough main rotor winding.

The flux due to this current induces an alternating emf in main stator winding.

GENERATOR PROTECTION RELAY

RPM>300 (PF output) Threshold 2.RPM>550 (PF output) Threshold 3.RPM>700 (PF output) Threshold 4.

RPM>840 (PF output) Engine over speed.Fault (PF output) Speed Sensing Failure.


44/94





Following indications are used,Thresholds i.e. TH1 to TH4, Over speed .In working order In healthy condition, this indication should be always present. If thisindication is not there, either RPM pickup input has failed or connection to the over speed

solenoid on compressed air module is loose or broken.

Following controls are possible,

Test This facility is to be used only when engine is in stopped condition. By pressing this button,engine RPM meter will reach up to 1000RPM and over speed solenoid valve on the air

module is operated.

Half speed test This facility is used to check OSPD safety when engine is running at speed of 840/2=420RPM. Bring speed about 400 RPM and press Half Speed Test button. Slowly startincreasing thespeed. When indication on RPM meter will cross 840 (actual engine speed420), OSPD safety should be operate as mentioned above.After operating above tests or in case over speed condition are rectified, press reset pushbutton.In case Engine over speed safety operates, with pressing reset button. Engine cannot be

started again.EFMU also gives 4-20 mA output corresponding to engine speed. This output is connectedto engine RPM meter on ECP, engine RPM meter on LSS and to 4-20 mA input module ofPLC.

THERMOCOUPLE

Engine is equipped with temperature sensors, to show the temperature of exhaust gas from

the respective cylinder heads and the temperature of turbo charger. The thermocouple isused as a sensor.

The thermocouple operates on the principle of Seebeck effect, when two dissimilar metals/alloys are joined together to form a closed circuit and the two junctions are held at differenttemperatures, then a voltage is generated. This voltage is due to the temperature differencebetween the two junction. The voltage generated is proportional to temperature.

The range of temperature measurement is from room temperature to 600 Deg. C, for alltypes of engines. Considering the temperature ranges & other factors like,

We uses K-type thermocouple as a sensor for exhaust gas temperature and turbo charger

temperature measurement. the typical range of K-type temperature sensor is -150 Deg. C.to 1400 Deg. C.

TEMPERATURE SENSOR RTD-PT100


45/94





DG Set is equipped with temperature sensor, to show the temperature lub oil, fuel oil, LTwater, HT water temperature, charge air cooler inlet and outlet temperature etc.

The resistance temperature detector (RTD) PT 100 is used as a sensor. The RTDoperates on the principle of change in the electrical resistance of a conductor takes placewhen there is change in temperature. The PT 100 is a positive temperaturecoefficient type RTD, means when temperature increases the resistance of the

conductor also increases. The output of the PT 100 is resistance, corresponding totemperature. The PT 100 sensor consist of 3 wires at the output. At 0 deg its resistance is100 ohm,the resistance increases by 4 ohm for every increase by 10 deg.

MAGNETIC PICK UP( SPEED SENSOR )

The magnetic pickup is used to detect the speed of the prime mover. Engine FrequencyMonitoring Unit (EFMU) which is mounted in the GCP is needed to convert thepickups output signal to one usable by the governor amplifier. The magnetic pickup

will produce a voltage output , when any magnetic material moves through themagnetic field. Most engines have flywheels or other large gears made up ofmagnetic material ( usually iron or steel). Magnetic pickups can usually be installed

without adding attachments to a gear or shaft. Non-magnetic materials, such asaluminum, brass and some stainless, will not excite the magnetic pickup. Anydevice which produces a dynamic discontinuity of magnetic material in the field of thepickup will produce an electrical voltage.
