Why Roots blower works under overcurrent? How to solve the overcurrent of Roots blower?

In use Roots blower During this period, the current is too high and the motor is overloaded. There are many reasons for the high current of Roots blower. Roots blower is a volume rotary blower. Its biggest feature is that when the pressure is adjusted within the allowable range, the flow changes little, the pressure selection range is wide, and it has the characteristics of forced gas transmission. Today, Xinqianshun will analyze the cause of Roots blower current?

1. Pipe blockage
The common reasons are that the pipe is blocked, the fan outlet is unstable, the wind does not go out, the pressure rises, and the motor causes overpressure overload, which leads to the rise of the Roots blower ammeter.
2. Causes of lubricating oil
     

If the lubricant of Roots blower is insufficient, the fan will continue to work without oil. The impeller failure friction and gear wear will increase, which will increase the motor load, which will only increase the motor load and accelerate the loss.
3. Improper operation
During operation, current overload may also be a problem. For example, if the check valve is installed in the opposite direction and the gate valve is not fully opened, this operation may cause the motor to burn instantaneously and should be carried out as specified during operation. Don't cause unnecessary trouble.
4. Problems of Roots blower
        Roots blower manufacturer It has its own quality problems. When installing the fan, the clearance of many parts is poor, which will lead to additional friction. In addition, some components may be damaged, increasing the load on the motor, and the fuse may blow.

In a word, if the current is too high, the roots blower motor will be in overload working condition, regardless of the fan's own reason or operation error. In daily use, in order to effectively avoid the failure of roots blower, we should follow the correct operation. Frequently stop and check the use method and process, and carry out maintenance and troubleshooting. This is an indispensable and effective method.
