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。

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

由于转速过高，使高粘度泵在运转时内部转子几乎只是形成了空转，围绕所输送介质打滑，造成吸不上料，或者是流量很小。

Due to high speed, high viscosity pump inside the rotor is barely formed when running idle, surrounding medium by sliding, cause not feeding, or flow rate is small.

它的最大特点是对介质的适应性强、流量平稳、压力脉动动小、自吸能力高，这是其它任何泵种所不能替代的。

It is characterized by a strong adaptability to the media, smooth flow, pressure pulsation, small, high self absorption capacity, which is not a substitute for any other pump.
