A distance piece provides the separation of the compressor cylinder from the compressor frame as shown in Figure 11-9. At the top of the figure…

Many variations and combinations of cylinder types and arrangements are available from the compressor manufacturers. The compressor manufacturer will generally make its selection based on…
A cylinder is a pressure vessel that holds the gas during the compression cycle. There are two basic types: 1. Single-acting cylinders are those where…
The compressor frame, shown in Figure 11-2, is a heavy, ragged casting containing all the rotating parts and on which the cylinders and crossheads are…
Each cylinder discharge line should have a relief valve located upstream of the cooler. Like all reciprocating devices, the piston will continue to increase pressure…
These valves isolate the compressor. Most operators require both shutdown valves to be automatic. Some operators use manual valves on small onshore compressors. If the…
A blowdown valve relieves trapped pressure when the compressor is shut down due to a malfunction or for maintenance. The flowsheet shows an automatic blowdown…
A speed controller can help extend the operating range and efficiency of the compressor. As the flow rate increases, the compressor speed can be increased…
A suction pressure throttling valve can also be installed to protect the compressor from too high a suction pressure. This is typically a butterfly valve…
As flow rate to the compressor increases, the suction pressure rises until the volume of gas at actual conditions of temperature and pressure compressed by…
