Oil Lubrication Pump Unit PB

1-3008-USOil Lubrication Pump Unit PB...

Multiline unit for total-loss oil lubrication systemson low and high-pressure compressors

Oil Lubrication Pump PB..

Applications on compressors for:

� delivery and storage of natural gas

� compression of combustible and process gases

� cold storage of liquefied gases

� extraction of biogas in clarification plants

� production of compressed air

� recovery of flare gas

� desulphurization of waste gases

General remarks

The PB oil lubrication pump unit is a multiline oil pump unit forthe lubrication of low and high-pressure compressors.

It consists of a modular piston pump with horizontal eccentricshafts, 1 to 8 adjustable pump elements per shaft and pumphousing as well as a drop regulator for each pump element. Alaterally installed set of gears with electric motor provides for anoptimum drive speed.

The pump’s main application is the total-loss oil lubrication ofcylinders and packings on piston compressors.

Every mineral, synthetic and ecofriendly oil can be delivered withthe oil lubrication pump unit.

Advantages

� Exact metering of lubricant for economy or full lubrication

� Adjustable delivery rates at each outlet port (for economy orfull lubrication)

� Different operating pressures and delivery rates (thanks to theuse of different pump elements) are possible on one pump

� Easy to change the number of outlet ports at later date

� Max. continuous operating pressures of up to 350 bars peroutlet port

� PB oil lubrication pump units are outfitted with 1-3 pumphousings to suit the application and with 1 to a maximum of8 pump elements per respective housing, or they can beexpanded at later date

� On the suction side PB oil lubrication pump units come withan integrated visual drop regulator and ball check valve foreach outlet port

� The electrical functions and filling level can be monitored withan SP/SFE 30/5 pulse generator

� Reservoir version to suit the customer’s wishes (incl. add-onslike heating, filling-level switch, etc.)

How the pump works

(See Figs. 1 and 2)

When the oil reservoir is filled, the oil in the pump housing (1) issimultaneously filled via an oil supply hole between the pumphousing (1) and oil reservoir (2) so that the eccentric shaft (3)rests in the oil bath. Even when the oil level in the oil reservoir (2)drops, this oil bath is maintained in the pump housing (1).

The lubricating oil for each pump element (4) is delivered fromthe oil reservoir (2) through the common intake tube (5) (1 intaketube per pump housing), the drop regulator (6) and the respectiveconnecting holes.

The underpressure produced by the pump and the stroke of thedelivery piston (8) draws oil out of the oil reservoir (2) into theupper part of the drop regulator (6). From there the oil is routedthrough a drop section down to the intake hole in the pumpelement (4).

A drop is tripped with each revolution of the eccentric shaft (3)and/or with each suction stroke of the piston. As a result, thefunctioning of every pump element (4) can be constantlychecked by way of the sight glass (7) on the drop regulator (6).

How the pump element works

(See Figs. 1 and 2)

The pressure stroke of the delivery piston (8) is force-actuated,and the suction stroke is returned by spring force (9). In thesuction stroke position (as drawn) the cross hole of the controlpiston (10) is closed.

When the pressure stroke begins, the delivery piston (8) closesthe intake hole (11). The lubricant drawn into cavity A is pressedagainst the spring-loaded control piston (10), the latter moving tothe right as a result. That opens the cross hole in the controlpiston (10). The lubricant makes its way under pressure throughthe lengthwise and cross hole of the control piston (10) intocavity B and from there via the ring duct and check valve (12) tothe outlet port.

The pressure stroke is followed by the suction stroke of thedelivery piston (8).

When the delivery piston (8) is moved, the control piston (10) isalso returned by spring force (9) to its initial position.

Underpressure is produced in cavity A by the suction stroke ofthe delivery piston (8).

When the intake hole opens, the lubricant flows into cavity A dueto the underpressure.

The pump element (4) is prepared for the next delivery stroke.

The delivery rate of the pump element (4) is determined by thestroke of the control piston (10) and can be adjusted with thesetting sleeve (WAF 14) (13).


Adjustment of the delivery rates

(See Figs. 2 and 5)

Clockwise turning reduces the delivery rate to as much asapprox. 30 %

(Minimum = 1 groove visible on pump element).

Counterclockwise turning increases the delivery rate by amaximum of 100 %

(Maximum = 3 grooves visible on pump element).

The delivery rate can be set in 8 detent positions betweenminimum and maximum.

Versions

The PB pump consists of 1 to 3 pump housings, each with amaximum of 8 pump elements. If fewer than 8 outlet ports perhousing are required, blank flanges are installed that can bereplaced at any time with a pump element. If a pulse generator(model SP/SFE 30/5) is used to monitor the reservoir’s fillinglevel, the maximum number of customarily possible outlet portsfor the pump unit is reduced by one port, since this port isneeded by the pulse generator to monitor the reservoir’s fillinglevel. The oil delivered is returned to the reservoir in this case.

The outlet port monitored by a pulse generator can, however,also be used a normal pressure port up to the maximum pumppressure (or as a reserve outlet port).
