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.
The crankshaft is connected to drive, to transfer the rotary motion.
When force lubrication is used, drilled oil passage is provided in the crankshaft.
Gives greater stability to the piston, eliminating piston “slap” and reducing ring wear
Permits stronger piston design and higher operating pressures.
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.
The most common material used in cylinder construction is cast iron for the larger, low-pressure cylinders and steel for the smaller, high-pressure cylinders. In some cases, nodular or ductile iron can be used in lieu of cast iron. For hydrocarbon service, steel is most desirable, although not universally available.
