In the process conditions permit, the change in pump flow, head, speed and medium operating temperature operating parameters, to avoid the occurrence of cavitation.

在工艺条件允许的情况下，改变泵的流量、扬程、转速及介质的操作温度等操作参数，可以避免汽蚀的发生。

Plasma separating technology is used widely in clinic, which is usually carried out by means of a single blood pump. The operator adjusts the rotate speed to change the separating speed.

血浆分离技术在临床上广泛使用，它一般由单血泵完成，操作人员凭经验调节转速来改变血浆的分离速度。

Under a certain speed in order to flow variables that is if the change of the flow pump the pump head power and efficiency of all subsequent changes.

在一定转速下，以流量为变量，也就是如果改变水泵的流量，则水泵的扬程、功率和效率等都随之而变化。
