Common reasons:
1. The damper in the intake pipe is not closed at startup;
2. The flow rate exceeds the specified value or the air duct leaks;
3. The density of the transport gas is increased to increase the pressure;
4. The motor itself causes;
5. The current is single line disconnected, the voltage is insufficient or lack of phase;
6. The coupling is skewed or unevenly spaced;
7. Bearing damage or severe vibration of the bearing housing;
8. The ventilator joint work deteriorates or the pipe network fails;
Corresponding treatment measures:
1. Close the damper when driving;
2. Close the small throttle valve and check for leaks. If it leaks, repair it;
3. Identify the cause, such as the gas temperature is too low, increase the temperature or reduce the air volume;
4. Identify the cause and eliminate its fault;
5. Check if the power supply is normal and voltage regulator;
6. Replace the bearing to eliminate vibration;
7. Adjustment, overhaul.
