　　What is the energy consumption of a closed cooling tower fan?

　　With the construction of the economy and the development of society, the problem of energy shortage is becoming increasingly serious. Closed cooling towers are widely used in key areas of industrial water and energy consumption.

　　Cooling tower is a key equipment for cooling water circulation and an important component of circulating water energy consumption. Under the environmental requirements of energy conservation and emission reduction, the energy conservation of cooling towers themselves is urgently needed! The speed and power of the cooling tower fan are independent, and this speed should only be due to the motor's usual slip rate S, which is usually not too large and can be ignored.

　　To check the speed of the cooling tower fan, it is first necessary to determine whether the fan is directly connected to the motor. If the gearbox is not connected, n=60f/p。 The AC frequency is 50, P is the number of pole pairs, and the reference motor voltage index.

　　If the motor is used for household electricity (220V), then P is 2. If it is used for industrial electricity (380V), P is 4, which can be calculated using the formula.

　　Maintenance method of closed cooling tower fan

　　The fan is one of the most important components in the operation of a closed cooling tower. Strictly following the effective maintenance plan for this component is beneficial for improving the refrigeration efficiency of the closed cooling tower, reducing energy consumption and noise. Closed cooling tower manufacturers will disconnect the switch power supply of the fan motor when inspecting the fan. Sometimes, sudden operation of the fan due to self starting is very dangerous. It is very dangerous for the fan to suddenly run during maintenance of the power supply system when the switch power is turned off.

　　Once a problem is found with the closed cooling tower fan, it should be immediately shut down for inspection.

　　2. Timely eliminate the dirt in the front, back, left and right pipes of the closed cooling tower fan to avoid safety accidents. The lubricating oil of the transmission system components should be replaced in a timely manner. The fan should adopt waterproof and rainproof measures outdoors.

　　When working conditions change, gate valves should be used to adjust the exhaust volume.

　　4. Accurately measure the current of the closed cooling tower fan motor. Under normal circumstances, the accurately measured current should be lower than the rated voltage.

　　After the production cycle of the fan is completed, maintain the motor to prevent corrosion and jeopardize its service life.

　　Before using the fan every year, add oil to the reducer before use.

　　7. Due to the simple structure of the closed cooling tower fan, it is crucial to pay attention to the maintenance of the intake system such as motor maintenance.

　　Due to the snow in winter, the fan is prone to deformation, so it is recommended to mark the angle of view of the fan impeller and remove the fan for installation according to the markings.

　　Maintenance of the rolling bearing part of the enclosed cooling tower fan: Regularly check the oil condition provided by the bearing lubricating oil. If there is oil leakage in the main chassis, the anchor bolts of the bearing end cover can be tightened a little, which is not good. It is likely that only new sealing fillers can be replaced. When the bearing lubricating oil is used normally, it should be replaced at least once within six months. When used for the first time, it should be done after 200 hours of operation. The time for the second oil change is 1-2 months. Afterwards, check the lubricating grease once a week. If the lubricating grease does not mold, the oil replacement work can be extended to 2-4 months. When disassembling and replacing, the required type of grease should be used (as required on the overall plan, the old oil in the car's fuel tank should be completely placed and cleaned, and then new oil should be introduced. If it is necessary to replace the fan rolling bearings, the following precautions should be taken: before installing the new rolling bearings, ensure that the rolling bearings and rolling bearing housing are very clean. Place the rolling bearings in oil with a temperature of about 70-80C, and then install them in the rolling bearings to prevent damage to the rolling bearings.
