Daily Maintenance Of Closed Cooling Tower

1. 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.
2. Spray pump and circulating water pump: When checking the water pump, be sure to cut off the power supply of the water pump. Sometimes due to reasons such as automatic operation, the sudden start of the pump is very dangerous.
   ⑴. When the pressure, flow rate, current, vibration, noise, etc. are very different from the usual ones, it is the precursor of the fault, and it is very important to deal with it. So please keep a running diary.
   (2) When the vibration is large, please check the installation of the piping or whether the foundation bolts are loose. Sometimes it is caused by the vibration of circulating water. When piping, it should be considered to install flexible joints, pressure vibration or absorbing devices.
   (3) If the outlet valve of the water pump is closed and operated for a long time, it will burn out the inside, so full attention should be paid.

⑷、Frequent start and stop will quickly burn the motor. Please use the following criteria to control the number of startups. Motor power Starting times Below 7.5kw Below 6 times/hour Below 11kw Below 4 times/hour
⑸, long-term stop operation or maintenance, if the internal water freezes when the water pump stops in winter, the water pump will be damaged by freezing. The pump must be insulated or the water inside must be drained.

3. Closed cooling tower Packing: Dirt will accumulate on the packing during the long-term operation of the equipment, which will affect heat transfer and ventilation, so it should be cleaned regularly with a medium-pressure water gun. To ensure the heat exchange of the packing.
4. Closed cooling tower Cooler: In the long-term use of the cooler, scale will accumulate on the coil, which will affect the heat exchange effect. Therefore, the heat exchanger should be cleaned regularly and a descaling agent should be added to the water collection tank.
   If improper protection causes the coil to freeze and burst, please contact our company in time. The design of the closed-circuit cooling tower professionally produced by GEWABIN has taken into account the convenience of daily maintenance and selection of the best materials in the industry, and its performance in antifreeze is particularly outstanding.
