Simulation and operating characteristics study of hydraulic system for 90 MPa diaphragm compressor
摘要
Abstract
To study the working characteristics of the hydraulic system of a 90 MPa diaphragm compressor,a mathematical model of its hydraulic system was established,and a simulation model was built based on this mathematical model.The reliability of the simulation model was verified with measured data.The model considered the working characteristics of components such as the hydraulic cylinder,servo valve,make-up oil pump,and plunger-cylinder liner,while also accounting for the compressibility of the hydraulic oil and the oil-gas interaction during actual operation.Using this simulation model,the dynamic variation curve of hydraulic oil pressure was obtained,and the influence of make-up oil volume on the maximum oil-gas pressure difference,as well as the impact of hydraulic oil compressibility on the p-V curve,were analyzed.The results show that as the make-up oil volume increased from 0.2%to 1.2%,the maximum oil-gas pressure difference in the first stage increased by 2.9 MPa,and in the second stage by 2.2 MPa.The compressibility of the hydraulic oil significantly affects the compressor suction volume,while it has a smaller impact on the indicated work per unit suction volume.When considering the compressibility of the hydraulic oil,the first-stage suction volume of the 90 MPa diaphragm compressor decreased by 4.29%,and the second-stage suction volume decreased by 19.6%.This research can provide a theoretical basis for the design of diaphragm compressors with high reliability and volumetric efficiency.关键词
