Suspension of cooling tower fill maintenance management approach

For the closed cooling tower, the fan, spray pump is the key components of the operation of the entire equipment, for the maintenance of these components, we must strictly abide by the necessary management practices, the following we combined cooling tower, for example, Detailed description of the relevant management practices:
1, the fan: the fan must check the fan motor power cut off. Sometimes due to automatic operation and other reasons, the fan will suddenly start a very dangerous. But also in the shutdown when the power to cut off to restore the power supply when the fan suddenly started very dangerous.

⑶, if the pump outlet valve closed for a long time running, will make the internal burn out, should pay full attention.
⑷, frequent start, stop will soon burn the motor. Please follow the following benchmarks to control the number of starts. Motor power start number 7.5kw or less 6 times / hour or less 11kw or less 4 times / hour or less
