Valve气阀
Reciprocating compressors generally use one of three types of valve configurations:
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.
Tangent Ring切线环
The tangent ring is cut into three segments so that each cut lies on the side of an
equilateral triangle. The cuts of this ring maintain sealing contact regardless of
variations of the ring’s inside diameter. If wear occurs in the tangent ring, the
garter spring will tighten the ring segments to compensate for the wear.
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.
