Analysis of Causes of Air Pump Motor Failure
source:Industry News release time:2021-08-27 Article author:Rosit Popular:Air band saw
Many users find that the motor coil is burned after using the vortex air pump. Why are the motor coils burned? A series of conditions will occur when the motor is overloaded, but the motor has few phases or some mechanical failure occurs.
When the vortex air pump is in use, the guide material is sucked in, mainly in the motor and pump head. After the foreign body enters, and generally, it will not cause any serious consequences. Of course, we must first have a concept of foreign matter. Some large particles are also foreign matter. Small metal parts such as screws will definitely seriously affect the normal operation of the fan. If some dust suction and filtration are not good, some dust particles will be inhaled. The situation will not be abnormal in a short period of time, but over time, the accumulation of foreign objects will cause a certain impact.
If there is foreign matter in the motor of the high-pressure vortex air pump, it will burn the motor. Although the motor is insulated, the foreign matter will be sent to the line after the motor is energized. At this time, the foreign matter will keep beating inside and rubbing will cause the paint. Remove it, which will cause a short circuit in the motor.
If foreign matter enters the wind drum of the vortex air pump, the wind blades will damage the wind bucket, the wind cover and the bearings, and it will also produce a certain amount of noise.
If the motor of the vortex air pump has a phase loss, the motor cannot start normally under normal circumstances, even if it is no-load, because it will increase with the speed, which will cause a buzzing sound. When the motor starts to smoke. When we open the end cover of the motor and disassemble it, we will find that a small part of the polar phase winding in the winding end has been zoomed.
If the vortex air pump has been running at a high speed, the shaft power of the motor will increase, and the current of the motor will be greater than the rated value at this time. When there is an overload phenomenon, all three sets of the vortex air pump will be burned. Therefore, if the vortex air pump wants to operate under such a situation, it must be properly decompressed or replaced with a more suitable fan. .
