ZX Series Centrifugal Pump self-priming pump the correct steps to use

August 20, 2022
Some people in the use of the pump, perhaps by feeling their own casual operation, so that non-standard operation may have some damage to the pump, affecting the life of the pump, Xiaobian now to explain the ZX series Centrifugal centrifugal pump self-priming pump operation steps, the only way to ensure the service life of the pump. ZX Series Self-priming Centrifugal Pump I. Preparations and Inspection Before Startup 1. ZX series centrifugal water suctions pumps are lubricated with high-quality calcium-based butter and No. 10 oil according to the working conditions of the pump. If the grease is lubricated with butter The pump should be regularly filled with grease into the bearing housing, the use of oil-lubricated pump, if the oil level is insufficient, then add enough. 2, check the pump casing is higher than the upper edge of the impeller, if insufficient, from the pump casing on the liquid directly into the pump body into the reservoir, should not start running liquid storage shortage, Otherwise, the pump will not work properly and the mechanical seal will be damaged. 3, check whether the rotating parts of the pump card credit bump phenomenon. 4, check the pump foot and the joints at the nut loose phenomenon. 5, check the pump shaft and motor spindle coaxiality and parallelism. 6, check whether the import pipeline leakage, if leaks, we must try to rule out. 7, open the suction pipe valve, slightly open (do not fully open) outlet control valve. Second, start and operation 1, point ZX series centrifugal water pump, pay attention to the steering shaft is correct. 2, pay attention to whether there is normal rotation and vibration and vibration. 3, pay attention to the pressure gauge and vacuum gauge reading, after the start when the pressure gauge and vacuum gauge readings after a period of fluctuation and indicate stability, indicating that the pump has been on the liquid, into the normal infusion operation. 4, the pump into the normal infusion operation before self-absorption process, special attention should be paid to increase the pump temperature, if this process is too long, the pump temperature is too high, then stop the pump to check the reason. 5, if the pump liquid temperature is too high and cause self-absorption difficulties, then you can temporarily shut down, the use of the liquid back to the pump back to the pump or to the pump body plus liquid reservoir directly to the pump to replenish the liquid so that Pump liquid cooling, and then start. 6, ZX series of clean water centrifugal pump in the course of their work as a strong vibration and noise, there may be pump cavitation caused by cavitation have two reasons: First, the import pipe flow rate is too large, the second is suction Too high. When the flow rate is too large, the outlet control valve can be adjusted to increase the pressure gauge readings, which should be promptly ruled out when there is a blockage in the inlet pipe. The suction height is too high to reduce the installation height of the pump. 7, ZX series of clean water centrifugal pump in the course of work for some reason to stop the pump, need to start again, the outlet control valve should be slightly open (not fully closed), so that both self-priming gas discharge from the outlet, and Can ensure that the pump starts under a light load. 8, pay attention to check the pipeline system leakage. Third, stop the pump 1, must first close the discharge valve on the pipeline. 2, stop the pump rotation. 3, in the cold season, should be stored in the pump body and the bearing body cooling water room to vent, to prevent cracking parts.
