The crosshead pin should have a replaceable bush bearing.
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.
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 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.
For lubricated service, metallic rings such as cast iron or bronze as well as non-metallic materials such as filled nylon are used. Nowadays the compressor manufacturers preferred non-metallic materials because of less weight and lower frictional force when compared with metallic rings.
