GDL vertical multistage pipeline booster pump common breakdown maintenance methods

GDL vertical multistage pipeline booster pump is widely used in high pressure hot and cold running system of water cycle and pressurization, high-rise buildings and many sets of parallel water supply, fire pump, boiler feed water and cooling water system and various flushing fluid conveying, etc. However, we often encounter some problems in use, let's take a look at GDL high-lift pressurized pipeline centrifugal pump common breakdown maintenance methods are there?

1, not out of the water pump, the water pump flow is insufficient

a, check whether the inlet valve is opened, in and out of the line block, block of impeller passage, such as removing obstruction;

b, check whether the motor running direction is correct, if motor open phase speed slowly,

c, whether suction pipe leakage; Whether the pump is filled with liquid, the water pump chamber air;

d, imported water supply is adequate, whether too high, suction bottom valve for leaks;

e, pipeline resistance is too large, pump selection is right.

2, too much power

over the rated flow, regulate traffic, turning down the outlet valve; The practical high absorption, water pump bearing wear.

3, noise vibration

the pipe support instability, liquid mixed with gas, produce cavitation, bearing damage, motor overload operation.

4, electrical heating

flow is too large, the overload operation, turning down the outlet valve; Local friction, motor bearing damage, lack of voltage.

5, the water pump leaking

mechanical seal wear and pump body with sand holes or broken, sealing surface uneven, installation bolt loosened.
