Causes of the burning of the slurry pump motor

What are the reasons for the burning of the slurry pump motor? The following editor will give you an introduction.

1. Moisture

The insulation degradation of the equipment due to water ingress or dampness is also a common cause of damage to the slurry pump motor, but there is no way to protect this phenomenon. Only pay attention to and regularly shake the insulation during use. Before exploding, drying and re-dipping paint can be solved. Especially for motors driven by inverters, you must be more careful about this, otherwise you may be reimbursed together with the inverter.

2. Overload

If the slurry pump motor has a protection function, it will generally not be overloaded. However, it should be noted that because the thermal relay cannot be calibrated, and the protection value is not very accurate, the selection is not appropriate, etc., and the manual setting is automatically reset, so when protection is needed, it often does not work, or there may be more After the second protection, no real reason was found, and the protection value was artificially increased, causing the protection to fail.

3. Lack of phase

This is the main reason why the slurry pump motor burns out. A motor of average quality will be finished in ten minutes. What is more terrifying is the lack of phase in the entire power supply system. In addition, many equipment switches are self-locking or automatically turned on. After a power outage, the lack of phase in the power supply may burn out. More than a dozen motors. The solution to a single motor is to install an electronic phase loss protector. In addition, the insurance in the motor circuit is also a cause of phase loss. So now, few people add a fuse or the like in the main circuit of the motor. It is better to install a suitable circuit breaker.
