Reasons for high pressure blower heating and low air pressure
1. Unstable Voltage: When the voltage is lower than the rated voltage, It is not only the problem of speed reduction. When the voltage is reduced, The motor will try to increase the current in order to maintain the speed and ensure the power. The current exceeds the rated value, The line loss increases, The voltage continues to decrease, The current continues to increase, The motor heats up rapidly, Accelerating the aging of the insulation or burning the motor. Another situation will also lead to heating, That is, The blower is overloaded.
2. The resistance of the pipe network increases: Check whether the pipeline is damaged or leaked, and whether the inlet and outlet of the fan are blocked by debris, Which affects the inlet and outlet of the blower.
3. If the internal bearing is damaged, Listen to the sound of the fan to see if there is any abnormal sound compared with the normal one, And confirm whether the bearing is damaged. If the bearing is faulty, There will be sound generally, And the operating load of the blower will be increased.
4. Check the positive and negative rotation of the motor. If it is reversed, Replace two of the three wires at random. Refer to the Wiring Diagram of High Pressure Blower:
Solution to High Pressure Blower Heating and Pressure Reduction
Check the motor heating. If the heating is serious, It will lead to loss of rotation. The heating is usually caused by overload operation. The motor can only be started again after timely troubleshooting. In addition, Check whether the cooling blower has problems.
