How to solve the frequent tripping fault of roots blower _ Roots blower:

Roots blower has the feature of stable operation, but if the operator does not operate properly, the Roots blower will trip. Let's see what causes the poor operation of Roots blower?
The unstable voltage is also one of the reasons for the protective power-off tripping of the aeration roots blower inverter. If the voltage is too low and lower than 360 V, the overcurrent protection of aeration roots blower will be cut off and tripped, otherwise, it will exceed 410 V, This will cause the converter to overheat internally and power off and trip. In the application scenario of Roots blower, when large equipment in the surrounding power grid starts and other factors lead to more violent voltage fluctuations, the power failure protection tripping of the fan will also be caused.

If one circuit of the rectifier template of the aeration roots blower frequency converter fails, the overcurrent protection will be cut off and tripped. Do not make too much dust inside the inverter or radiator of the aeration roots blower, which will lead to poor heat dissipation, and then the roots blower will be powered off and tripped. If the internal clearance of roots blower rotor, cavity, etc. becomes smaller due to long-term rust and dust, the resistance will increase, which will lead to overload and power off protection.

How to solve the fault of roots blower

How to solve the stuck common fault of roots blower _ Roots blower:

1. Precautions for startup

If the roots blower does not start with no load, it will trip or suffocate. When starting, remember that the roots blower starts with no load.

2. Simple tripping

In case of simple tripping of roots blower, it will not cause damage to roots blower. At this time, what should be done is to open the vent valve, start the fan, and check the operating condition of the fan.

3. Motor burned out

If the motor is burned out and the three blade roots blower cannot be started, then we need to replace the motor, and the loss is relatively serious. Roots blower cannot hold pressure, which may easily lead to motor damage and sudden bearing pressure of fan

A very serious situation will occur.
