Chemical pump in the use of the process, usually by supporting the motor to bring power, the correct selection of supporting the motor is very important.
1. First, according to the location, frequency and power factor of the chemical pump, determine the level and type of the motor.
2. Chemical pump conditions are more complex, the choice of motor according to the altitude, the outside temperature, the transmission of the medium and pump installation of the situation to use the motor, for example, some of the environment need to use explosion-proof motor.
3. Also according to the operating parameters of the chemical pump, to determine the motor speed, the best consideration to energy-saving factors.
4. According to the requirements of the use of chemical pumps to choose the type of matching motor, in the selection process will take into account the motor starting, braking, inversion, speed, frequency modulation and other factors to choose from.
5. According to the use of the chemical pump load, speed regulation, frequency modulation, start to choose the frequent degree. If the motor power is too large, then the efficiency of the pump is reduced, so that the electric energy is wasted, the resource and the cost increase, so the type and power of the motor must be chosen correctly.
