Causes of motor burning of submerged slurry pump

Liquid slurry pump is one of the commonly used equipments. In recent years, it has been deeply loved by everyone. In order to let everyone know better, let's share with you the reason why the motor burned down. Please come and have a look with me. 1. The lack of phase can be said to be the main killer of underwater slurry pump motor. The average mass of the motor will be completed in ten minutes. What is even more frightening is that the whole power supply system is out of phase. In addition, many switches of the equipment are self-locking or automatically opening. Once the power is cut off, the power transmission will be out of phase, which may burn more than a dozen motors. The solution for a single motor is to install an electronic phase-missing protector. 2. For the motor under the liquid slurry pump, the insulation reduction caused by water ingress or damp is also a common cause of damage, but there is no way to protect it. Please pay attention to and shake insulating materials regularly during use. Drying and re-impregnation before explosion can solve this problem. 3. Too many. If the motor of the immersed slurry pump has protection function, it will not be overloaded. However, it should be noted that the thermal relay cannot be calibrated and the protection value is not selected accurately. And it is set to automatically reset artificially, so when protection is needed, it usually fails to achieve the effect or has been protected for many times, so in order to maintain the normal use of the underarm slurry pump equipment, it is necessary to find out the cause.
