System Installation; Entrapped Air Removal - GE H301 Series Operating Manual

Never replace a divider block valve with one of a different size
number and/or letter. The block change affects all oil routed
through the divider block assembly. Changing one block size

System installation

The cylinder lubricator pump is cam driven off the compressor crankshaft's speed
reduction gear train located in the compressor's auxiliary end housing.
Proper Supply (Head) Pressure to Cylinder Lube Pump
The standard cylinder oil supply from the compressor frame lubrication system at
normal operating pressure of 45 to 55 Psig (310 to 380 kpa) provides positive filling
of the cylinder lube injection pump.
Some compressor applications or end user preferences require different
compressor cylinder oil than that used in the compressor crankcase. In these
applications, the cylinder oil supply is disconnected from the crankcase lubrication
system. A separate reservoir (oil day tank) is installed to supply the compressor
cylinder oil. To ensure proper operation of the lubricator pump, put the bottom
of the oil supply tank at least 3 feet (1 meter) above the lubricator pump inlet.
Consider oil flow and temperature when determining the line size and the height
of the oil day tank. Cold ambient temperature affects oil viscosity, and can cause
reduced oil flow to the pump inlet. Cold ambient temperature affects oil viscosity
and can cause reduced oil flow to the pump inlet.
The non- supply end of the reservoir should be lower than the supply end allowing
space to collect condensed water and debris that may enter the reservoir. A drain
valve in the non-supply end of the reservoir may be periodically opened to drain
condensed water and debris.
To improve cold weather oil supply flow to the lubricator
pump, supplemental heat (electric or engine coolant
circulation type heat tracing and insulation of the day tank

entrapped air Removal

Removal of entrapped air from the pump unit and the lubrication system is critical
to achieving reliable oil delivery. To properly fill and purge air or gas:
1. Allow the oil to flow to the lubricator pump inlet. To purge and fill the
complete system, manually operate the pump or connect an oil gun to the
pump outlet.
2. Purge and fill divider blocks and tubing:
may cause catastrophic failure.
