Independent Oil Supply
When process gas
composition and
cylinder operating
conditions require
an independent cyl-
inder and packing
oil supply, the
resulting separate
force feed lube sys-
tems require an oil
supply. Lubricator
oil is supplied
under pressure
from an elevated
tank. To prevent the
compressor frame
oil from being con-
taminated by the
force feed oil, be
sure that the lubri-
cator box over flow
does not drain into
the crankcase. The
lubricator box over
flow tubing must be
disconnected from
the compressor
frame and directed
to an appropriate drain system.
Independent force feed lube systems require oil with a viscosity below 5000 SUS (1100 cSt)
at the lubricator pump inlet. Measures which may be necessary to make sure that the force
feed pump is filled with oil during the suction stroke include; appropriate pipe and fitting size
from the tank to the force feed pump, heating the oil, and pressurizing the supply tank. An in-
line oil filter or fine screen is required between the supply tank and the force feed lubricator
pumps. Recommended filtration is 5 micron nominal.
Force Feed Lubrication System Components
Gas Inlet Debris Screens to Maintain Lube Performance
Even when the proper rate and lubricating medium are in use, dirt and foreign matter in the
gas will prevent the lubricant from performing properly. Prior to start-up, cone type inlet gas
debris strainers with 100 mesh per inch (150 micron) screen and perforated metallic backing
are to be installed in a pipe spool between the inlet scrubber and cylinder suction flange. In

Questions and answers
The vent that is on the jgp/2, should it be venting continuously?
The provided context does not specifically mention whether the vent on the Ariel JGP/2 should be venting continuously. However, it does state that vents and drains should be designed to prevent the collection of liquids that could cause gas or liquid buildup. It also mentions that primary vents and drains should be independently vented from secondary vents and drains. Based on this, it is likely that the venting behavior would depend on the system's design and operating conditions rather than a continuous venting requirement.
