Vertical pipe centrifugal pump used in China is mainly composed of impeller, pump body, pump shaft, bearing, seal ring, stuffing box and other components, each component doing its job in the vertical pipeline centrifugal pump The use of vertical pipe centrifugal pump for many reasons, not easy to use, then we will bring vertical pipe centrifugal pump failure analysis and solutions introduced. Vertical pipe centrifugal pump failure analysis and solutions 1, the phenomenon of the phenomenon: the pump can not discharge Fault Analysis: a. Rotation in the opposite direction; b suction or discharge valve is closed; c inlet or pressure is too low; solution: a Confirm the direction of rotation; b. Confirm whether the valve is closed; c. Check the valve and pressure gauge; 2, symptoms: insufficient pump flow Failure Analysis: a suction or discharge valve is closed; b inlet pressure is low; c outlet blockage ; solution: a confirmation valve is closed; b check that valves are open; c confirm the amount of discharge is normal; 3, fault phenomenon:... an abnormal sound failure analysis:. a large coupling eccentric or poor lubrication; b motor. Fault; c. Reducer abnormalities; solution: a. Find or fill the grease; b. Check the motor; c. Check the bearings and gears; 4, the phenomenon of the fault: the current is too large Fault Analysis: a. Outlet pressure is too high; b. melt viscosity is too large; c. shaft seal assembly bad; solution: a. check the downstream equipment and pipelines; b. test viscosity; c. check the shaft seal, appropriate adjustments; : a. Blackout; b. Motor overload protection; c. Coupling Damage; d. The outlet pressure is too high, interlocking reaction; Solution: a. Check the power; b. Check the motor; c. Open the safety cover, disk car inspection; d. Check the instrument interlock system; Through the above analysis, we must have a vertical pipeline centrifugal pump failures of a more profound understanding, we can see from the example, even if the cause is a problem with its production of more than one might believe that this will solve the user to generate vertical pipeline centrifugal pump failure A certain influence, but I believe in the experience of the previous guidance and work summary of the usual work experience, the user will be able to solve the problem well.
