Pipeline centrifugal pump failure analysis and solution

【Centrifugal Network News】 Pipeline centrifugal pump is used to transport clean water or physical and chemical properties of water like centrifugal pump equipment, which is mainly used in industrial, construction, garden fire and other fields. Pipeline centrifugal pump in the course of once there is a problem, the pipe centrifugal pump efficiency will have a significant impact on workers need to pipeline failure analysis of centrifugal pumps to do enough homework, if we can find a solution in time better. Pipeline centrifugal pump failure analysis and solutions 1, Pipeline centrifugal pump can not start or start the load large failure analysis and solutions are as follows: (1) The prime mover or power is not normal. The solution is to check the power and prime mover conditions. (2) pump stuck. The solution is to hand-drive coupling inspection, disintegration inspection, if necessary, to eliminate static and dynamic part of the fault. (3) packing pressed too tight. The solution is to relax the packing. 2, pipeline centrifugal pump is not drainage failure analysis and solutions are as follows: (1) insufficient irrigation pump (or pump gas is not row finished). The solution is to re-pump. (2) The pump is not turning properly. The solution is to check the direction of rotation. (3) pump speed is too low. The solution is to check the speed, increase speed. 3, after the pump discharge fluid failure analysis and solutions are as follows: (1) suction pipe leakage. The solution is to check the suction side of pipe connections and stuffing box seal situation. (2) Suction side of the pump gas is not discharged finish. The solution is to ask to re-pump. (3) Suction side suddenly blocked by foreign bodies. The solution is to stop the pump processing foreign matter. Through the above analysis of the pipeline centrifugal pump failure and solutions introduced to the pipeline centrifugal pump we have a better understanding. In this era of rapid development of science and technology, the speed of upgrading equipment is often inconceivable. Pipeline centrifugal pump if you want to maintain a strong market competitiveness, the need for failure analysis to do more work.
