Fluid flow in a screw pump oil supply system for reciprocating compressors

Screw Compressors for Heat Pump Application

A Diagnostic System for Reciprocating Compressors

An advanced warning system for maintenance and control of reciprocating compressors is discussed. The compressor is instrumented to measure valve temperatures, interstage pressures and temperatures, rod drops, packing temperature and leakage flow, and numerous other variables. Under control of a microcomputer, a scanner monitors the sensors and updates a database. After a scan, an expert progra...

Heat Transfer in Oil-Flooded Screw Compressors

Thermodynamic efficiency of the compression process in oil-flooded screw compressors depends greatly on the oil-gas heat transfer process. The amount of heat transfer is a function of many parameters such as mode of oil injection, oil inlet temperature, etc. This paper describes a mathematical model to calculate this heat transfer, assuming that the oil is injected in the form of non-interactin...

Stress analysis of reciprocating pump pipeline system in oil station

The strong vibration of reciprocating pump in oil transportation station pipeline system will seriously affect the safe running of the equipment and pipeline. And the resonance between pipe and equipment will cause more severe damage. Therefore before the formal operation of station, not only static stress analysis, but also modal analysis and vibration analysis are necessary for the reciprocat...
