Numerical Analysis of Resistive Torques during the Start up of a Reciprocating Compressor

摘要：

Most simulation methodologies for compressors available in the literature consider a steady state operating condition.However,several phenomena that affect the compressor energy efficiency,noise level and reliability are associated with transient effects that occur when the compressor is either switched on or switched off.This paper presents a numerical analysis of the compressor start up,with special attention to the resistive torques that take place in the first compression cycles.The results show that the equalization pressure level greatly affects the torque that the electrical motor must overcome during the compressor start up.
