Setup And Adjust Lubricator Pump - GE H301 Series Operating Manual

76 | Chapter 6: Lubrication
a. Loosen tube nuts at all injection points. (Cylinder and packing.)
b. Loosen the tube nut at divider block and loosen the four socket head
screws at the inlet end of the block.
c. Loosen a connection in the manifold block located on top of the pump
unit, and the inlet connection to the no-flow switch.
d. Operate the manual pump, filling the system until clear air-free oil
appears at each disconnected point in turn.
e. Retighten loose connections starting from the manifold block in sequence
to the divider block inlet and socket head screws.
f. Continue pumping until air-free oil is discharged at all injection points.
g. When all lines have been filled and tightened, operate the pump for a few
additional strokes and check for leaks or malfunctions.

Setup and Adjust Lubricator Pump

All lubricator pumps on HSR compressors have a .375" (9.52 mm) maximum stroke
length. The effective stroke length is adjustable and determines the actual flow
rate from the lubricator pump. The plunger diameter maybe .25" (6.35 mm) or .375"
(9.52 mm) depending on the required oil volume and process gas pressures.
Set and adjust the oil flow rate by adjusting the effective stroke length of the
plunger. Set the break-in oil flow to the maximum pump output flow rate. The oil
flow percentage through each injection point is predetermined when the divider
block sizes are selected. The oil flow percentage can't be changed by adjusting the
pump.
