How to maintain the closed cooling tower water pump

　　Last time, I introduced you to the problem of several pumps required for closed cooling towers. Today, I will show you how to maintain the water pumps of closed cooling towers.YMNCooling tower noise reduction treatment manufacturer

　　The closed cooling tower water pump refers to the self-injection water pump of the closed cooling tower. The closed cooling tower manufacturer China trlon air-conditioning self-injection water pump selects high-quality mechanical equipment water pump seals that will not be converted to restrictions, no leakage, long life, It also uses a special outdoor motor and a uniquely equipped bearing manufacturer to ensure the long-term reliable operation of the pump, with the advantages of small output power, large flow, and low noise. The following is a detailed introduction to everyone on how to maintain the water pump in the closed cooling tower.YMNCooling tower noise reduction treatment manufacturer

　　1. In addition to the harsh application of water pumps according to the installation manual, two points should be paid attention to:YMNCooling tower noise reduction treatment manufacturer

　　One is not to rely solely on "work experience". For example, when the bottom valve of the water pump sees water, some operating manuals are convenient. Before each start, fill some sandy soil into the inlet branch pipe, and then flush the soil through the bottom valve to make the bottom valve impermeable. This method seems simple and easy to implement, but it is not desirable. Since the gravel and soil in the bottom valve will enter the pump with the water when the pump starts to work, it will damage the centrifugal impeller, pump body and shaft, etc., which will seriously harm the service life. The appropriate method should be to repair the bottom valve. If it cannot be repaired, replace it.YMNCooling tower noise reduction treatment manufacturer

　　The second is that common faults should be eliminated immediately, and the generator set should not be operated "with faults". For example, if you find that the filling material of the water pump shaft is seriously damaged, you should raise the filling material immediately, otherwise it will cause the water pump shaft filling material to leak steam. The leakage of the filling material of the water pump shaft not only causes excessive energy consumption of the generator set, but also causes cavitation, which accelerates the destruction of the centrifugal impeller, immediately endangering the service life of the water pump. For another example, if you find that the water pump is making a big sensation, you should turn it off for inspection first, otherwise, if the water pump is bent or deformed, it is likely to cause a safety accident.YMNCooling tower noise reduction treatment manufacturer

　　2. After a period of application of the closed cooling tower water pump, the following protection and maintenance operations should be done.YMNCooling tower noise reduction treatment manufacturer

　　(1) Drain the remaining water in the pump and pipeline.YMNCooling tower noise reduction treatment manufacturer

　　(2) If the disassembly and assembly are convenient, the water pump and pipeline can be unloaded and wiped out neatly.YMNCooling tower noise reduction treatment manufacturer

　　(3) Inspect the rolling bearing. If the inner and outer clothing is damaged, moved, steel ball is damaged, or the surface has black spots, it must be replaced. The rolling bearings are neatly arranged with gasoline or gasoline used in automobiles, and then coated with unsalted butter for storage.YMNCooling tower noise reduction treatment manufacturer

　　(4) Check whether there are cracks or small round holes on the centrifugal impeller, whether the nut is loose, whether it is fixed on the centrifugal impeller, whether it should be repaired or replaced. Check the gap at the centrifugal impeller anti-friction ring, if it exceeds the standard value, it should be repaired or replaced.YMNCooling tower noise reduction treatment manufacturer

　　(5) If the pump and pipeline are not disassembled, use the rear cover to seal the inlet and outlet to prevent dirt from entering.YMNCooling tower noise reduction treatment manufacturer

　　(6) If the rubber cloth of the power transmission system is not needed, it must be washed with warm water and stored in a place without direct solar radiation, or in a place with oil, corrosion, and smoke. No matter what the situation is, it is not necessary to stain the tape with raw oil chemicals such as car oil, diesel engine or car gasoline, and it is not necessary to apply rosin and other viscous chemicals to the tape. Before the tape is applied, the hoarfrost on the surface of the tape must be removed.YMNCooling tower noise reduction treatment manufacturer

　　(7) Clean all the screws and anchor bolts neatly with a steel brush, and coat them with automobile oil or immerse them in a diesel engine for storage.YMNCooling tower noise reduction treatment manufacturer

　　(8) Do a good job of cleaning up the usual closed cooling tower.YMNCooling tower noise reduction treatment manufacturer
