on the block shows the rate at which the block is cycling.
From the distribution blocks, oil travels to the cylinders and packings. The system provides
1 inch min. (25 mm) of head at the guide and cylinder inlets to help ensure long check valve
life.
Some of the oil to the packing travels through to the cylinders, but the bulk of it is drained out
through the pressure vent/drain fitting on the bottom of the crosshead guide and through the
atmospheric drain also in the bottom of the guide.
An oil level control valve, supplied by the packager and mounted on the skid, maintains prop-
er level in the crankcase sump to replace oil used in cylinder lubrication.
Force Feed Lubricator Adjustment
See instructions under “Force Feed Lubricator Adjustment” in Technical Manual Section 3.
NOTE: THE FORCE FEED SYSTEM MUST HAVE A BLOW-OUT FITTING WITH A
PROPERLY RATED RUPTURE DISK, INSTALLED IN THE TUBING LINE
BETWEEN THE FORCE FEED LUBRICATOR PUMP AND THE NO-FLOW
SHUTDOWN. THE DISK COLOR SHOULD SHOW AT THE FITTING BLOW-OUT
HOLE. THE FORCE FEED SYSTEM MUST HAVE A WORKING NO-FLOW
SHUTDOWN SET TO ACTUATE WITHIN THREE TO FIVE MINUTES AFTER
INTERRUPTION OF THE LUBRICATOR OIL FLOW.
CAUTION!: USE A MIRROR TO VISUALLY INSPECT FOR PROPER RUPTURE DISK
COLOR, IF THE FORCE FEED SYSTEM IS PRESSURIZED. A RUPTURING
DISK OR HIGH PRESSURE OIL CAN POTENTIALLY CAUSE PERSONAL
INJURY.
