Observe the operation of the electrical system of the evaporator cooler fan

The electrical system of the evaporator cooler is a very important part. In the course of its use, it is necessary to maintain the operation of the electrical system by using the evaporator cooler.
1, check the evaporative cooler fan fan remote control point box components are normal.
2, continuous open and shut down operation, check the remote control is correct and reliable.
3, evaporative cooler fan fan test run two hours, observe the motor bearing temperature, motor temperature rise is within the normal range.
4, the control valve mechanical opening and closing action is flexible, reliable, open and close angle mark is clearly visible.
5, the indicator light and the voltmeter, ammeter are normal, evaporative cooler fan parts of the operation of all different sound, three-phase current value is balanced.
Regularly observing the use of the electrical system of the evaporator cooler fan can effectively improve the safety of the equipment and reduce the occurrence of the evaporator cooler fan failure.
