DTE uses reputable components in its products, whereby DTE will reduce the risk of faults in its machines. This also applies to the water pumps. These pumps are made with a stainless steel fan, a high quality pump house and a “Mechanical seal” to seal the axis. The mechanical seal is a high quality axis seal made from polished hard metal, and all contact surfaces are polished. This will guarantee a good sealing even under the toughest operating circumstances. The mechanical seal will lubricate itself by means of a thin liquid layer of the pumped fluid. When the machine has not been used for a long period there is a chance that the water pump will not run. The cause of this fault may be cohesion between the polished contact surfaces of the mechanical seals. The seals "stick together". This problem is easily solved by rotating the pump axis by hand. In the Grundfos pump, it can be done by first removing the roster by unscrewing the two screws. You can now rotate the engine fan by hand. The sticking together has now been broken and the machine can be started. (See Figure 5.27 and Figure 5.28) CAUTION! MAKE SURE TO REPLACE THE ROSTER, OTHERWISE THE PUMP ENGINE WILL NOT BE COOLED PROPERLY!

INTRODUCTION Semi-closed and closed cooling systems are used in many processes. An efficient and effective cooling system is needed for a process to function without problems. Generally such cooling systems contain between 0.5 and 5.0 m³ water, which is normally topped up with tap water. The tap water available is often, technically speaking, of poor quality:

contains limescale and/or

is corrosive The system may contain many different materials with which the cooling water comes into contact. Such as:

steel/cast iron

copper/brass

aluminium

synthetics/sealants PROBLEM DEFINITION Corrosion problems can occur in cooling systems, which have different causes. The presence of different materials can result in galvanic corrosion, which is where the least precious metal is dissolved. The action of oxygen on iron and steel causes oxygen corrosion and the formation of iron oxide or silt. Natural silt accumulation can lead to “under deposit corrosion”. High flow-speeds can lead to erosion corrosion. The quality of the cooling water plays a significant role in this.

GENERAL MEASURES

Contamination Measure

Mechanical contamination caused by iron oxides or silt Install filters, depending on contamination

High hardness Soften water via ion exchange

Minor contamination caused by presence of oxides and hardness

Use water treatment in the form of hardness stabilisation and corrosion inhibitors

Biological contamination caused by presence of algae and slime bacteria

Use water treatment in the form of biocides

WATER TREATMENT

Specific water treatment should be used if one or more values cannot be maintained or achieved. Water treatment products can be used for a wide variety of applications in this case. DTE has a water treatment in the form of PollutionMaster. This product can optionally be supplied. If the temperature of the water exceeds approx. 40°C, (partial) water softening must in general be applied. A complete water treatment proposal can be drawn up after the water quality has been assessed on site. CLEANING

If the cooling system is already very contaminated, we recommend cleaning the system with a suitable cleaning product. The cleaning solution can be pumped around using the system pump or an cleaning pump. For the best cleaning result, at least some flow should be established across all components. The cleaning progress can be monitored through visual inspection and using pH test strips. Systems with considerable biological contamination should be rinsed thoroughly first. A bio-dispergator can also be used for this purpose. The cleaning method and costs will be assessed and determined per situation. Note: You can contact DTE anytime.

1144..44 GGuuiiddlliinnee ffoorr wwaatteerr qquuaalliittyy iinn DDTTEE iinnssttaallllaattiioonnss

Water quality for use in all DTE installations is prescribed in this general guideline. Water quality used in DTE installations should meet this standard at all times. Standard values for water quality:

- Acidity: PH 7 < PH 9,5 - Chloride: < 50mg / L - Conductivity: 150 µS < 350µS - Bicarbonate (HCO3): 80mg/L < 100mg/L - Hardness: 2dH° < 8dH°

This directive is a general directive which also applies to systems in which water with a percentage of glycol is used. In cases where a water-glycol mixture is to be applied, the quality of water must first be analysed to be ensured the water quality is within the norm values. Subsequently, a water-glycol mixture may be prepared that must be tested on mixing ratio before use. In the system the absorption of oxygen must prevented to keep the hydrogen carbonate (HCO3) level within the acceptable range. In case of doubt, this should be tested with a sufficient frequency.
