Closed cooling tower maintenance measures for the management of key parts

For closed cooling tower, fan, spray pumps are key components of the equipment operation and maintenance for these parts, we must strictly comply with the necessary measures for the administration, below we with complex flow closed cooling tower as an example, detailed introduces the related management measures: 1, fan: must be at the time of check the fan will fan motor power cut off. Sometimes due to reasons such as automatic operation, the wind suddenly start dangerous opportunity. And when stop a little bit to cut off the power supply, to restore power fan suddenly start is very dangerous. (1), confirm whether the blade deformation, damage, or the presence of dust, dirt and other attached objects. In addition, confirm with blade clearance tower body surface on the circumference of a circle is uniform. In addition to any abnormalities. Diction, frequent start will stop blower motor malfunction. Operation method should be paid attention to, make the control start times under 4 times/h. 2, spray pump, circulating pump: when up water pump, must will pump power cut off. Sometimes due to reasons such as automatic operation, the pump suddenly start is very dangerous. (1), pressure, flow rate, current, vibration and noise in one area is different from that of normal is a sign of failure, the process is very important. So please do work diary. Diction, big vibration, please check whether the piping installation problems or foundation bolt is loose. Sometimes is caused by vibration of circulating water, should be considered when doing piping installation of flexible joint, pressure or vibration absorption device. (3), if the water pump outlet valve closed for a long time, can make the internal damage, should take note. (4), frequent start, stop, burning motor soon. Inquire the following benchmark control start times. Motor power 7 start times. Below 5 kw under 6 times 11 kw/h the following below 4 times/h. 5], to stop the operation and maintenance for a long time, the winter water freezes if inside the pump stops, the pump will be freezing. Must be carried out on the water pump insulation or internal temperatures drop.
