speed of the pump meaning in English

泵转速

This hydraulic system is controlled by different pump ' s flowrate , which is realized by changing the speed of the pump , instead of changing pump ' s displacement
这种系统不是靠改变泵的排量而是靠改变泵的转速来改变其输出流量,从而实现对液压系统的控制。
In addition , in order to make the pumps realize constant injection pressure , the expert tuning pid vfvs constant injection pressure control sub - system for pumps is established and relevant software module is developed . the sub - system can control automatically the quantity and rotate speed of the pumps running to realize the pumps optimum run according to the seawater injection plan of the oil field , which realizes constant injection pressure , energy saving and decreases the consumption to a large degree
此外，为平台注水泵机组的优化运行构建了基于专家整定pid控制的变频调速恒压注水控制子系统，并开发了相应的软件模块，完全省却了pid控制器的硬件设备，使得注水泵机组可以根据油田注水量的配注方案优化运行，自动控制注水泵的转速和运转台数，既能实现平稳增压注水，又能在很大程度上节能降耗。
