Although circulating water vacuum pump after years of development, has gradually been able to meet the needs of the market, but in the course of use, circulating water vacuum pump will have sick, aging, so this time circulating water vacuum pump is particularly prone to Failure, when these failures occur, not only will affect the working efficiency of circulating water pump, but also more likely to exacerbate the circulating water pump aging. Next, we will introduce common problems of circulating water vacuum pump, but also analyze the fault solution what? Circulating water vacuum pump failure analysis and solutions 1, circulating water vacuum pump failure due to lack of flow pipe, circulating water pump impeller impeller blockage, scale deposition, lack of valve opening: remove the obstruction, to re-adjust the valve opening; centrifugal pump voltage Low: Regulated; Impeller wear: Replace the impeller; Exceeds the rated flow Use: Regulates the flow of small off valve; Centrifugal pump suction is too high: lower suction; Pump bearing wear: Replace the bearing. 2, circulating water vacuum pump fault noise vibration causes pipe instability: a solid pipeline; liquid mixed with gas: to enhance suction pressure exhaust; produce cavitation: reduce the degree of vacuum; bearing damage: replace the bearing; Regulate the flow off small outlet valve. 3, circulating water vacuum pump failure water is not the cause of the import and export of hot water pump valve is not open, out of the pipeline obstruction, abortion impeller blockage. The solution is to remove the obstruction. The motor runs in the wrong direction. The motor is out of phase. The speed is very slow. Adjust the direction of the motor. Sturdy motor wiring. Circulating water vacuum pump Suction tube leakage: Tighten the sealing surfaces to eliminate the air. Cavity with air: Open the pump cover or open the exhaust valve, drain the air; import and export of insufficient water, suction stroke is too high, the bottom valve leakage: stop checking, adjustment; pipe resistance is too large, improper selection of centrifugal pumps: Reduce the pipe bend, re-select the pump. Every life seems to be unable to escape the fate of illness and death, from birth to death sickness, we must be strong, for the circulating water pump, it is also a living object, scientists and workers gave it life In the face of problems that may arise during the work process, what we need to do is not to complain. We need to support it, find out the cause of the failure, and find a solution whenever possible. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
