Lubrication System
Force type lubrication is used for the medium and heavy-duty compressor. The main
component of the force type lubrication is the main oil pump, dual oil filter, lube
oil cooler, pressure regulating valve, lube oil tank and its associated accessories.
Splash type lubrication is used for the small compressor(up to 100kW). This type of
system lubricating oil by the splashing of crank-throw moving through the lubricant
in the sump.
Permits a longer stroke and greater capacity.
Separates crankcase from the cylinder, allowing control of oil carryover into the cylinder.
The packing rings are the important element of rod packing assembly. The below-listed
packing rings are widely used in a reciprocating compressor.
The Figure shows a drilled crankshaft.
Crankshafts should have removable balance weights to compensate the rotary unbalance
as well as reciprocating unbalances. The crankshaft should be dynamically balanced
when above 800 rpm.
Backup Ring支承环
The construction of the backup ring is similar to the radial ring. As the name
indicate this type of ring is used to backup all the rings when using in the high-
pressure application.
In the case of lubricated cylinders, the distance piece prevents also keep a synthetic lubricant in a cylinder from being corrupted by the crankcase lubricant.
