constant-pressure pump

基本解释

This paper compares two methods of realizing multi-pump constant-pressure water supply by an AC drive.
多泵变频恒压供水常用的两种方案，比较了两种方案的优劣。
Finally, taking the constant pressure pump as example, we make YB-20AH axial piston pump with constant pressure optimized by this method.
最后以恒压泵变量机构为实例，对YB-20AH型柱塞式恒压主量泵变量机构进行了寻优设计，并取得了良好的效果。
The applied plan is introduced of frequency control system by the microcomputer for constant -pressure water supply to circulating pump stations, and the system is analysed.
介绍了微机控制变频恒压供水系统在循环泵站中的应用方案，并对系统进行了分析。
