The electric feed pump motor will be effectively connected according to the applicable range, applicable place and economic factors of different applications, etc. The pump and motor are connected in the following ways:
1. The shaft of the pump is directly connected to the motor shaft.
2. The shaft of the pump is connected to the motor shaft through the coupling.
3. The shaft of the pump is connected to the motor shaft through the gearbox.
4. The shaft of the pump is connected to the motor shaft via a fluid coupling.
Load characteristics of electric feed pump motor
The load on the electric feed pump motor is related to the lift and flow of the pump. When the pump with high lift is working at the high lift point, its flow rate is the flow at the design point. When working at low lift, it is equivalent to the decrease of the outlet resistance of the pump. At this time, the flow rate of the centrifugal pump will increase, and the pump motor will be overloaded. If it exceeds a certain level, it will burn the pump motor.
Overcurrent prevention of electric feed pump motor
1. Avoid overloading the equipment and make the pump motor run at rated current or over rated current for a long time. Since the starting current of the pump motor is 3-5 times of the rated current, special care should be taken to avoid starting the equipment with load or full load.
2. The pump motor works in a damp working environment. Before the pump motor starts, check the ground insulation and phase insulation of the coil. During the operation of the pump motor, pay attention to the waterproof and moistureproof of the pump motor.www.lanhai-globals.com
