摘要
介绍了带负载敏感的恒压泵的工作原理。分别对使用普通换向阀和含定压差阀的换向阀作为控制元件,并结合单负载和双负载组成的恒压与负载敏感系统进行了理论分析,并对两种系统的运用进行了对比总结。
The working principle of the constant pressure pump with load sensing is introduced.Using general reversing valve and differential pressure reducing valve as the control elements respectively,the constant pressure and load sensitive system composed of single load and double load are analyzed theoretically.The application of the two system is compared and summarized.
