Causes of burning of Roots vacuum pump
When designing the Roots vacuum pump, the technicians made some adjustments to establish the characteristics of the Roots pump, such as efficient and stable operation. Due to its performance characteristics, large Roots vacuum pumps can achieve higher speeds, but in actual use In China, everyone has opinions on the phenomenon that the Roots vacuum pump is burned, so why is this?
Analysis of the causes of large roots vacuum pump burning:
1. Leakage: Roots vacuum pump is immersed in water, so leakage is one of the important factors leading to combustion.
2. Cable breakage and damage: Cable breakage and damage are not only easy to cause electric shock accidents, but also in the Roots vacuum pump unit, it may be in a two-phase working state during operation, which is neither stagnant water nor easy to damage the motor.
3. The power supply voltage or frequency is too low.
4. When the rotor is locked, the stator winding will generate a locked-rotor current. The locked-rotor current is 5 to 7 times the normal full-load current. If it is not protected, the vacuum device will soon be burned. There are many reasons for the rotor jamming, Such as impeller jamming, mechanical seal fragments stuck on the shaft, dirt winding, etc.
5. Wear and corrosion: Wear will greatly reduce the performance, flow, head and efficiency of the vacuum unit, and the impeller and pump cover will rust and cause the rotor to lock.

1. Reasonable speed. If the length of the stator and rotor of the high-speed screw pump is very short, it is very easy to wear, which directly affects the service life of the pump. The speed regulating mechanism or the deceleration mechanism can be used to reduce the speed to keep the speed within a reasonable range. The service life is several times longer than the high-speed screw pump.
2. Keep the product clean. Since many sewage plants are equipped with a crusher in front of the pump, although a grille device or filter is installed to prevent debris from entering the Roots vacuum pump, the grille should be cleaned in time to avoid blockage. At the same time, ensure that debris does not enter the pump body.
3. After working for a period of time, overhaul should be carried out. It can be adjusted according to the working environment to check whether there are aging parts. If found, replace them in time. In addition, it is necessary to regularly check the oil level position of Roots vacuum pump and whether there is any abnormal sound. The oil pipe needs to be cleaned at the same time of maintenance. When Roots vacuum pump is stopped for a long time, all pumps need to be disassembled and the water inside.
4. Regularly change the oil,Roots vacuum pumpDuring use, you need to observe the changes in oil volume, pay attention to the replacement of related parts, replace the oil in time, lubricate the rotating parts and joints, and keep them properly, which can extend the service life and make the equipment operation more flexible.
I wish you all a happy life and see you next time.
