Fire pump motor overload, not necessarily the quality of the motor, but related to the pump head. agricultural pumps manufacturersThat is, the head with submersible pump is different from the head. For example, when our pump is working, the rated head of the fire pump is 60 meters. But if you use this head 20, it will bring a lot of load to the motor.agricultural pumps manufacturers
When the load of the motor increases, it is easy to have problems, if the problem is serious, the motor will be burned. This is what we usually call the overload operation of the motor. It can be seen that the motor is often burned out, which is not necessarily a quality problem of the motor.agricultural pumps manufacturers
In general, fire pump motors have a fixed operating power, which is called the rated power in watts (watts). If in some cases the actual power used by the motor exceeds the rated power of the motor, this phenomenon is called motor overload.
The overload of fire pump motor mainly has the following symptoms:
1. The motor current exceeds the rated value. When the temperature rise of the motor exceeds the rated temperature rise, the heat output of the motor increases substantially.
2. The speed of the motor is down.
3. The motor makes a low hum.
4. If the load changes sharply, the motor speed will rise and fall.
The motor of the fire pump contains electrical reasons, such as phase deficiency, voltage exceeding the allowable value, etc. There are also some mechanical reasons, such as excessive torque, motor damage (bearing vibration) and so on.
