Working Principle
Stuffing Boxes
In reciprocating compressors, the piston is connected to the crankshaft via a piston rod that passes through a sealed chamber known as the stuffing box. This chamber includes a distance piece, which separates the crankcase from the compression chamber and provides space for the sealing elements.
The primary function of the stuffing box is to isolate the crankcase from the cylinder. To achieve this, specialized packing elements are installed to prevent crankcase oil from entering the compression chamber and to stop process gas from leaking back into the crankcase. This sealing system is critical for ensuring reliable compressor operation, minimizing contamination, and maintaining system pressure.
