Considerations for reciprocating compressors for processing units

Jun 29, 1994 · The balanced plug unloader is designed to use the energy of the compressed gas to assist actuation. This minimizes the force required to load, allowing low pressure plant air to be used for actuation. The plug style unloader uses a pneumatically actuated plug assembly to open and close a center port of a specially designed pressure valve.

for maintenance. Valves and unloaders cause around 44% of unscheduled reciprocating shut down and this selection has a strong effect on reliability. For small machine, spill back is optimum solution, because power is low. For big machine optimum configuration is selection of part load steps based on plug/port unloader and clearance pocket.

For lubricated service, the force feed lube oils the top of the ring set at a very low rate because this ring set is not subject to cylinder pressures and temperatures. The end-to-end seal in the cup and the low lube rate of AL ring sets, ensures newly installed rings run virtually dry for the first few hours of operation.

Hydraulic pumping is a proven method of artificial lift -- adding energy to move the fluids to the surface after reservoir pressure is no longer sufficient to do so. The key component of a hydraulic pumping operation is the downhole pump. The two basic types of installations are the "fixed"-pump and the "free"-pump design.

compressor is a two cylinder single stage, reciprocating compressor with a rated displacement of 13.2 cubic feet per minute at 1250 RPM. The compressor assembly consists of two major subassemblies, the cylinder head and the crankcase. The cylinder head is an iron casting which houses the inlet, discharge, and unloader valves. (See Figure 1). The

An unloader valve is the component of a pressure washer that allows the pump to bypass the flow of water back to the pump while the spray gun is not being used. Most unloader valves also act as a pressure regulator for the output pressure of the pump.

For divider valves stamped with a "T" (for "twin"), use a 1/8 inch (3.2 mm) pipe or tubing plug to plug only one base outlet when testing that side of the piston, and leave all other outlets open. Plug and test each base outlet of divider valves stamped with a "T" one side at a time. See FIGURE 3-17 "Testing 'T' Divider Valve
