Causes and countermeasures for excessive motor current and temperature rise

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 disconnected from the single line, and the voltage is insufficient or lacks 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.
