Cylinder Lubrication Flow Rate And Cycle Indicator - GE H301 Series Operating Manual

Too much oil
Oil strains through both plies of tissue paper. Oil may be pooled at bottom of
cylinder bore, discharge passages, valves, or covers. Return compressor to service
and reduce cylinder lube rate (increase cycle time) by 10 to 20%. Perform cylinder
oil film wipe test again in 200 to 300 operating hours.
Too little oil
Cylinder walls are dry and oil does not strain through the first tissue paper ply.
Return compressor to service and increase cylinder lube rate (reduce e cycle time)
by 10 to 20%. Perform cylinder oil film wipe test again in 200 to 300 operating
hours.

Cylinder lubrication Flow Rate and Cycle indicator

The cylinder divider block illustration sheet, provided to the packager, lists the
divider block sizes, and guidelines for minimum oil flow rates, and the resulting
maximum cycle time. Due to operating and gas conditions precise lubrication
rates can't be provided.

After setting the lubricator flow rate, check the cylinders for proper oil film at
approximately two-day intervals during the first week and every six months
thereafter.
Packing may be checked for proper lubrication by periodically examining the
piston rods. The piston rod surfaces should be bright and coated with a thin layer
of clear clean oil. Black and dirty oil, scoring marks, or heat discoloration on the
rod are indicative of packing wear that may be due to insufficient lubrication.
A precise lubrication rate for the cylinders and packing cannot be furnished due to
various operating conditions encountered.
For break-in on initial startup, set the pump at full flow. Reduce the oil flow rate
and check the cylinders and piston rods for proper oil film at approximately two-
day intervals during the first week and every six months thereafter. See the
maintenance checklist" and the
A cycle indicator or other flow measurement device, mounted on the divider
block, is a visual indicator of cylinder lubrication operation. The indicator pin, an
extension of the piston in the divider valve block, cycles back and forth as the
piston moves. A pin cycle is measured from the time the pin is at it's outermost
position until it returns to this position. Typically the indicator pin cycles several
times a minute. The time it takes to complete one cycle determines the oil flow
rate.
