(Urgent attention) Roots Blower What happened when the motor started for a while smoked?
Today, the factory received a customer who said that once the Roots blower purchased from another company was started, it would smoke. I don't know what it is We contacted the technicians and summarized the following points, hoping to help you in your work and avoid accidents:
In general, the motor of Roots blower is burnt for the following reasons:
1. Check whether the motor runs without phase?
If the motor loses phase during operation (the disconnection of any phase in the three-phase winding is called phase loss), the fan vibration will become larger, abnormal sound will appear, speed will drop As the flow increases, the temperature of the motor will rise sharply, which will cause the motor to burn out. An ordinary motor will burn out for more than ten minutes at most. And the pressure gauge is overflowing In case of overpressure, overpressure may lead to various faults of the fan.
2. Whether the head or bearing is damaged, the bearing is improperly assembled, or worn, or the bearing machining accuracy is not enough, which causes the inner and outer rings of the bearing not in the same section, causing bearing operation and processing, and causing motor burning. Abnormal sound or jamming caused by head failure or improper assembly of bearing, or quality problem of bearing itself.
3. Check whether the check valve is installed reversely. If the check valve of Roots blower is installed reversely or the angle is incorrect, the blower will be suffocated and the motor will be burned directly.
4. Check whether the on-off valves on the main pipes of roots blowers are open: if multiple roots blowers are connected in parallel, the on-off valves on the main pipes should be opened in time, otherwise the exhaust of roots blowers will be blocked, causing the roots blowers to run under load and burn the motor.
5. The outlet diameter of Roots blower changes greatly compared with the diameter of the main pipe. In this case, the pressure will rise instantaneously. It is recommended to change the diameter of the pipe when laying the pipe. Do not burn the motor due to pressure increase caused by pipe design problems.
The above is what Xinqianshun Roots blower manufacturer shared for everyone about the burning of the motor when it is in use. Before starting the Roots blower, strictly abide by the fan manual to operate, pay more attention to avoid overload during operation, learn more about the use precautions of Roots blower, do a good job in maintenance, and extend the service life of Roots blower. Please contact us if you don't understand in use.
