How to choose a motor for molten salt pump? 
The matching motor of molten salt pump should be selected according to the requirements of the use, and should pay attention to the following aspects: 
1, according to the performance parameters of the molten salt pump to select the motor speed, general motors. When the molten salt pump head is relatively high, you can choose between two poles motor. 
2, according to the use of molten salt pump to determine whether the use of explosion-proof, if the explosion, then further determine the level of explosion-proof. 
3, according to the process requirements of the heat transfer system, determine whether the molten salt pump matching motor need to speed, if you need to speed, should choose a variable frequency motor. 
4. According to the voltage, frequency and power factor of the occasion, the voltage level and the type of the motor are determined. 
5, according to the molten salt pump of energy-saving requirements of energy-saving electric motor, need to remind you that, molten salt pump energy saving effect is greater than the motor energy saving effect.
