Symptoms
cause of issue
Method of exclusion
1, horizontal centrifugal pump does not water
a, import and export valves are not open, out of the pipeline blocked, runner impeller blocked.
b, the motor is running in the wrong direction, the motor phase loss is very slow.
C, suction tube leak.
d, horizontal centrifugal pump is not filled with liquid, the pump cavity with air.
e, imported insufficient water supply, suction stroke is too high, the valve leaks.
f, pipe resistance is too large, improper pump selection.
a, check, remove the blockage.
b, adjust the motor direction, tighten the motor wiring.
C, tighten the sealing surface, remove leakage.
d, filled with liquid and open the exhaust valve, drain the air.
e, downtime, inspection, adjustment (water pipe or suction pipe with easy to use this phenomenon).
f, reduce pipe corners, re-select the pump.
2, horizontal centrifugal pump insufficient flow
a, first press 1. Reason check.
b, pipes, horizontal centrifugal impeller impeller blockage, scale deposition,
Valve opening is not enough.
C, the voltage is low.
d, impeller wear.
a, first press 1. exclude.
b, remove the blockage, readjust the valve opening.
C, regulator.
d, replace the impeller.
3, horizontal centrifugal pump power is too large
a, more than the rated flow use.
b, suction is too high.
C, horizontal centrifugal pump bearing wear.
a, adjust the flow, off the small outlet valve.
b, reduce.
C, replace the bearing.
4, horizontal centrifugal pump noise vibration
a, unstable pipe support.
b, liquid mixed with gas.
C, cavitation.
d, bearing damage.
e, the motor overload heating operation.
a, a solid pipeline.
b, improve suction pressure exhaust.
C, reduce the degree of vacuum.
d, replace the bearing.
e, adjust press 5.
5, horizontal centrifugal pump motor fever
a, traffic is too large, overloaded operation.
b, rub rub.
C, motor bearing damage.
d, the voltage is insufficient.
a, off the small outlet valve.
b, check and exclude.
C, replace the bearing.
d, regulator.
6, horizontal centrifugal pump leakage
a, mechanical seal wear.
b, horizontal centrifugal pump sand hole or broken.
C, sealing surface is not flat.
d, Loose mounting bolts.
a, replace.
b, welding repair or replacement.
C, trim.
d, fastening.
