How to do the fire pump motor overload ?

What is the fault of the fire pump motor, and what is the cause of the overload of the fire pump motor?

In the face of the overload of the fire pump motor, I believe you have a lot of doubts, then, in the face of the fire pump motor overload, the following are listed solutions.

Why is the fire pump motor overloaded? What should I do if the fire pump motor is overloaded?

Before we understand the fire pump motor overload remedy, let’s take a look at the cause of the motor overload.

Of course, it may also be due to other special circumstances, such as the leakage of the head.

The main reason for the overload of the fire pump motor is four: the temperature rise of the motor exceeds the rated temperature rise, the heat generated by the motor increases greatly; the motor speed decreases; the motor current exceeds the rated value; the motor load changes drastically, causing the motor speed to fluctuate; the motor appears Noise, such as low-pitched sounds.

So, what are the remedies we can do in the face of overloading the fire pump motor?

First, do a good job of prevention, and increase the heat of the motor. Relevant personnel should sum up experience and do preventive work after knowing why it is fever.

Second, timely remediation, such as because the fire pump motor load is too heavy, you should consider appropriate load reduction or replacement of the appropriate capacity of the motor, the power supply voltage is too high or too low, you can install the power supply voltage regulator cabinet for remediation, and, for example, For example, if the transmission part of the fire pump mechanism fails, the motor is overloaded and the motor winding is burnt out. At this time, it is necessary to check the fault of the mechanical part and prescribe the right medicine.

Third, do a good job of inspection between parts, fire pump if it is often operated, then the relevant personnel need to check the bearing wear situation intermittently, if it is not qualified, you need to replace the new bearing; secondly, clean the bearing and inject a proper amount of grease. Then check the motor end cover. If the center hole of the end cap is worn out due to wear, the end cap should be treated or replaced.

Fire pump motor overload is a common obstacle. In this respect, people in the industry have experience, but fire pump overload is a common problem, and it should not be taken lightly.
