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.
The connecting rod is made up of forged steel for 150 kW (200 hp) reciprocating
compressor. For compressor less than or equal to 150kW, ductile iron material is
used.
The compressor can use narrow piston, due to the use of narrow piston larger valve area for greater efficiency.
Bearing
The main and connecting rod bearings should be split-sleeve, steel-backed, babbitted
insert type. Antifriction bearing shall be used for compressor rating less than
150kW. As per API-618 trapper roller bearings are used as the main bearing for
compressor rating less than 150kW.
Connecting Rod连杆
Purpose of the connecting rod is to connect the crankshaft and the crosshead. The
connecting rod converts the rotary motion into reciprocating motion. The connecting
rod bolts and nuts shall be securely locked with cotter pins or wire after assembly.
Like Crankshafts, the connecting rod has drilled hole for oil passage.
Distance piece may be furnished as single, double, or extra-long type.
The purpose of longer distance piece is to prevent the lubricant entering from crankcase to cylinder. Thereby preventing the gas contamination due to lubrication entering in the cylinder side.
