Selection of design parameters of automatic ring valves of reciprocating compressors

Abstract

One of the main tasks at designing and operation of reciprocating compressors is provision of energy efficient and reliable operation of the automatic valves. Imposed to the automatic valves is a number of requirements (low gas-dynamic impedance to valve flow, timeliness of valve closing, etc.) the fulfillment of which requires multi-variant calculations in order to select efficient valve parameters for the specified operation modes. Given in the study are the results of valve design analysis depending on the compressor operating conditions (at change in the crankshaft speed) and valve parameters (at change in spring tension and maximum valve stroke).
