Vogel Single Line Progressive Lubrication Systems Presented by: Ricardo Gomez

Single Line Progressive System Basic

Features

Description

System distributes grease using progressive feeder valves

Hydrostatically sealed spools output metered lubricant

Output is a function of back pressure and pump flow

Proportional distribution of lubricant

Sequential feeding of lube points

Operating pressure range:

10 – 200 bar

Metered quantities:

0.08 – 3.6 cc

Viscosity range: oil and fluid grease (20cSt – NLGI 3)

Progressive System Layout

Grease Pump

Controller

Progressive Feeder with cycle switch

Main Feeder

Compared to piston distributors, progressive feeders do not operate in strokes – they deliver the amount delivered by the pump divided into the number and size of the pistons. They operate one after the other in a feeder.

Family of Progressive Feeders

Typical applications:

- oil circulating systems for presses - transfer lines - conveyors/chains - material handling - parts washer - etc.

Piston 4 is under pressure – piston 1 delivers lubricant to the outlet.

Piston movement of 1 / 4 opened connection between main line and piston 5

Piston 5 is pressurized and piston 2 delivers lubricant to outlet 2a.

PSG 2 Progressive Feeders Features

PSG 3 Progressive Feeders Features

Variable quantity per outlet from 0.004 - 0.2 cu. in.

Blind elements for expansion or removal of segments

Solid base plate construction-minimizing number of sealing elements-and consequently number of potential leakage points. Also, eliminates over tightening concerns of segmented block construction, which creates leakage. REMEMBER: Leakage in the block construction eliminates the monitoring feature of a progressive feeder-blocked line. That is, a blocked line cannot be detected if the seals associated with that outlet are leaking.

PSG Modular Feeder Technology

Integrated check valves on every outlet

ISO 228-1179 & SAE ports standard

10 mm / 3/8 “ tube accessible on outlet

Check valves integrated into fittings with elastomeric seals

Integrated bleed ports

Captive O – rings. There are 81 loose o-rings in our competitors design. The PSG has Zero. Imagine the possibility of pinching or loosing an o-ring in during assembly.

PSG Modular Feeder Technology

Common Metering elements-Conversion of Twin to Single accomplished is base plate

Solid state piston sensing proximity switch

Integrated filter possible

Integral flow control valves are available- fixed and adjustable- optical or electrical feedback- pressure compensating- gear wheel flow control possible

Progressive System

Layout for NLG1-2 System

- Instead of the whole system only zones, controlled areas by solenoid valves are supplying lubricant.

The controller runs the zones in a configured order for a defined time.

Single Line Progressive Systems

Advantages

• Rugged, versatile design

• Modular construction is possible

• Low cost monitoring of spool

movement

Disadvantages

• System design, layout and installation time and material intensive

• Field alterations of system are difficult

• Metering is a function of back pressure and velocity

• Low volume metering is not reliable

• Installation is costly

• Minimum volume – still large for total loss

• MTBF studies would indicate low up-time (multiplication factor)

• Series system

• Susceptible to air locks

• Additional possible leakage points
