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。
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.
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。
Under this situation, we must reduce the speed of pump, increase the power of the motor, increase the import and export of pipe diameter to reduce the flow resistance of the medium.
在这种状况下，必须降低泵的转速，加大电机的功率，加大进出口的管径来减少介质的流动阻力。
Transport high viscosity medium, low speed pump to be elected, if the low viscosity, the corresponding high-speed selectable.
输送高粘度介质时，泵应选低转速，若粘度较低，相应可选择高转速。
Because the medium viscosity directly affects the choice of high viscosity pump speed.
因为介质粘度的高低直接影响到选择高粘度泵的转速。
If the high viscosity pump medium viscosity is too high, and with the rotation speed is too high, will cause the pump flow rate is very low, the noise of the pump is very large.
如果高粘度泵输送的介质粘度过高，而所配的转速也过高的话，就会造成泵的流量很低、泵的噪音很大。
Mainly is the pump speed is too high, medium and high viscosity resistance is very big, this will cause pump motor moment of starting current more than rated current, motor overload;
主要是泵的转速太高、介质粘度又太高这样就会造成泵阻力很大，电机的瞬间启动电流超过额定电流，造成电机过载；
Mainly is the pump speed is too high, medium and high viscosity resistance is very big, this will cause pump motor moment of starting current more than rated current, motor overload;
