Environmental protection, energy saving and maintenance methods for closed cooling towers?

Environmental protection, energy saving and maintenance methods for closed cooling towers?

  How many water pumps does a closed cooling tower need? There is no immediate response to this question. Because of the overall design of the closed cooling tower, in the cooling plan presented by the customer, the installation of water pumps is generally carried out according to the specific situation, the total number of water pumps and the cooling temperature, A series of factors such as refrigeration water flow and circulation system conditions are related. In the case of the design scheme, the number of water pumps should not be too high, otherwise it would be a waste of electromagnetic energy. If it is too low, the requirements for cooling circulating water will not be met. Finally, the cooling requirements cannot consider customer satisfaction. Pay attention to environmental protection and energy saving.ZQvCooling tower noise reduction treatment manufacturer

  How to make the closed cooling tower water pump more environmentally friendly and energy-saving?

  First: The equipment of the closed cooling tower water pump needs to be effective, not a large car, and when the system software does not require large flow and high pump head, it can be equipped with a smaller one, and the load change for the back-end development is great. Under the circumstances, the principle of frequency converter can be used to determine the necessary total flow based on the heat exchange rate, which can be environmentally friendly and energy-saving.ZQvCooling tower noise reduction treatment manufacturer

  Second: Effectively design the pipeline, reduce the additional frictional resistance of the pipeline, and remove the filter device on time.ZQvCooling tower noise reduction treatment manufacturer

  Third: According to the working temperature, the self-spray closed cooling tower water pump can complete an automatic control system or achieve a certain environmental protection and energy saving effect, which is aimed at the primary circulating water system.ZQvCooling tower noise reduction treatment manufacturer

  Fourth: When the actual effect of heat transfer in the back-end development is not very good, it should be handled properly to ensure low total flow supply under normal import and export trade temperatures, without the need to increase the total flow to ensure.ZQvCooling tower noise reduction treatment manufacturer

  Fifth: Regular maintenance and identification of the main operating parameters of the closed cooling tower water pump, to prevent the centrifugal impeller or turbine shell from damage and flow back, and to promote additional damage.ZQvCooling tower noise reduction treatment manufacturer

  How to maintain the closed cooling tower water pump

  The closed cooling tower water pump refers to the self-spraying water pump of the closed cooling tower. The closed cooling tower self-spraying water pump of Guangdong Trlon Energy-saving Air Conditioning Equipment Co., Ltd. uses high-quality mechanical equipment water pump seals that will not be restricted, no leakage, long Long-term reliable operation of the pump is ensured by the use of a dedicated outdoor motor and a uniquely equipped bearing manufacturer. It has the advantages of low output power, large flow, and low noise. Below is a detailed introduction to everyone on how to maintain the water pump in the closed cooling tower.ZQvCooling tower noise reduction treatment manufacturer

  1. In addition to strictly following the installation manual for the application of water pumps, two points should be noted:ZQvCooling tower noise reduction treatment manufacturer

  One is not to rely solely on "work experience". For example, when a water pump has a bottom valve seepage, 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 looks simple and easy to implement, but it is not desirable. When the water pump starts to work, the gravel and soil in the bottom valve will enter the pump with the water, damaging the centrifugal impeller, pump body and shaft, etc., which will seriously harm the service life. The proper way should be to repair the bottom valve. If it is really impossible to repair, replace it.ZQvCooling tower noise reduction treatment manufacturer

  The second is to clear the common faults immediately, and do not let the generator set work "with faults". For example, when you find that the filling material of the water pump shaft is seriously damaged, you must raise the filling material immediately, otherwise the water pump shaft filling material will leak steam. The leakage of the water pump shaft filling material not only causes excessive energy consumption of the generator set, but also causes cavitation, which accelerates the destruction of the centrifugal impeller, and immediately endangers the service life of the pump. For another example, if the water pump is found to vibrate strongly, it should be shut down for inspection first, otherwise, if the water pump is bent and deformed, it is likely to cause a safety production accident.ZQvCooling tower noise reduction treatment manufacturer

  2. After a period of application of the closed cooling tower water pump, the following maintenance work should be done.ZQvCooling tower noise reduction treatment manufacturer

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

  (2) If it is convenient to disassemble and assemble, the water pump and pipeline can be removed and cleaned and tidy.ZQvCooling 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 cleaned and tidied with gasoline or gasoline for cars, and then stored with unsalted butter.ZQvCooling 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.ZQvCooling tower noise reduction treatment manufacturer

  (5) If the pump and pipeline are not disassembled, use the rear cover to seal the entrance and exit to prevent dirt from entering.ZQvCooling 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. In either case, 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 coat the tape with rosin and other viscous chemicals. Before applying the tape, remove the hoarfrost on the surface of the tape.ZQvCooling tower noise reduction treatment manufacturer

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

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