基于流体脉宽调制的定量泵负载敏感系统能耗分析
Energy consumption analysis of load sensitive system of fixed displacement pump based on fluid pulse width modulation
摘要
Abstract
In order to reduce the energy consumption of the load sensitive system of a fixed displacement pump,the valve group composed of load sensitive valves in the pump control system was replaced by a two-dimensional pulse width modulated rotary valve,and a load sensitive system based on fluid pulse width modulation was designed.According to the working principle of the load sensitive system,the AMESim simulation model of the system was established,the load sensitive characteristics and energy consumption of the system were simulated and analyzed,and an experimental platform was built for experimental verification.The results showed that the combination of two-dimensional pulse width modulated rotary valve and fixed displacement pump made the system load sensitive,so that the fixed displacement pump output power and load consumption power changed with the load,which reduced the overflow loss and improved the energy saving effect of the system.关键词
