Reciprocating Compressor Piston Rod Load
In this article, we learn about the Reciprocating Compressor Piston Rod Load – Principle and Calculation method. The compressor rod load exceed the recommended rod load (ie., Combined Rod Load) of a reciprocating compressor leads to major compressor failure. For this reason, it is important to understand the rod load during the design stage and startup of the compressor.
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.
Cross Head十字头
All industrial compressors are equipped with crosshead. The crosshead is used to
guide the piston in the cylinder bore. The following are the advantage of the crosshead.
Rod Packing活塞杆填料
Rod packing is required to prevent the gas leakage along the piston rod where it
passes through the crank end cylinder closure.
The crosshead pin should have a replaceable bush bearing.
For the larger capacity compressor, cylinders are provided with replaceable linear.
In smaller capacity compressors, particularly for single stage models the replaceable liner is not economical and may not be available.
The cylinders are equipped for the cooling arrangement to reduce the temperature rise during the compression cycle. This is usually by means of a water jacket if water jacketing in the cylinder is not feasible than fins are provided in the cylinder for air cooling. The latter method is limited to either small or special purpose machines.
