Closed Cooling Tower Fan Maintenance

Closed cooling tower fan: When checking the fan, be sure to cut off the power supply of the fan motor. Sometimes due to reasons such as automatic operation, the fan will start suddenly, which is very dangerous. And when shutting down, the power supply must be cut off at one point, and it is very dangerous to start the fan suddenly when the power supply is restored. (1) Confirm whether the blade is deformed, damaged, or has any attachments such as dust and dirt. In addition, confirm whether the gap between the inside of the tower body and the blade is uniform on the circumference. Other than that there are no exceptions. ⑵, frequent start and stop of fan motor will cause failure. Attention should be paid to the operation method so that the number of starts is controlled below 4 times/hour.
