Traditional compressor cylinder designs require cooling water jackets to promote uniform distribution of heat created by gas compression and friction. Some of the perceived advantages…
The allowable rod load depends on rod diameter and material, and will be quoted by the manufacturer. The actual load can be calculated from the…
To enhance compressor flexibility it is desirable to design into the compressor the capability of operating at other than the original design conditions. If it…
Using a known piston displacement and efficiency, the gas throughput can be calculated from:
The flow rate is not directly equal to the piston displacement. Volumetric efficiency is the ratio of actual volumetric flow at inlet temperature and pressure…
The actual volume of the cylinder that is swept by the piston per minute is piston displacement. It can be calculated from: Single acting cylinder…
Typically, in specifying a unit, the suction and discharge pressures, capacity (MMscfd), inlet temperature, and gas properties are given. The actual sizing of the cylinders…
Clearance is the volume remaining in a cylinder end when the piston is at the end of its stroke. This is the sum of the…
Inlet valve unloaders are used to deactivate a cylinder end and reduce its capacity to zero. Two of the more common types of unloaders are…
The compressor valves control the flow of gas into and out of the compressor cylinder. All valves are similar in that the differential pressure across…
