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. In case of ordinary tripping, the roots blower will not be damaged due to the simple tripping of 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. The motor is burnt out. If the motor is burnt out and the roots blower cannot be started, then we need to replace the motor, and the loss is relatively serious. Roots blower cannot hold the pressure, which may easily lead to motor damage, and the bearing pressure of the fan will suddenly rise, which may cause serious problems.
The capacity of the frequency converter is not accurate in the selection process, and the parameters are slightly small. Therefore, the frequency converter selection of the aeration roots blower must exceed the rated power of the motor by about 20%. In this way, the power failure and tripping of the aeration roots blower will be avoided when the load is slightly high.
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, if the voltage exceeds 410 V, the converter will be overheated and cut off and tripped. 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, resulting in 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.
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 roots blower cannot be started, then we need to replace the motor, and the loss is relatively serious. Roots blower cannot hold the pressure, which may easily lead to motor damage, and the bearing pressure of the fan will suddenly rise, which may cause serious problems.
I believe that after reading the above, you should also know how to deal with the tripping of Roots blower. I hope it will help you.
