Pit pump flow instability should be how to deal with

the usefulness of pit pump and pay attention to?

1, the necessary equipment in the solid foundation pit pump frame or on the ground, should not be loose.

2, check before starting:

( 1) The connecting parts fastening;

( 2) Motor rotation direction should be correct;

( 3) The clutch active and reliable;

( 4) Piping to connect and robust, reliable sealing, bottom valve loose useful.

3, before starting, sleeve, bottom valve, it is necessary to fill the water in the pump body, the top filled with oil pressure gauge buffer.

4, roll with the hand, make the piston reciprocating twice, no ZuGeng and not no-load starting line insulation good, after starting to work again normal gradually increasing load.

5, homework often test of mud sediment concentration should not beyond 10%.

6, a few of the gears of mud pump to make the splash lubrication, reliable and should be a few files in each class assignments speed operation respectively, time is not less than 30 seconds.

7, homework in sound or heavy, pressure is not normal, water or significant high temperature should stop pump inspection.

8, pit stop land pump for long, should be completely clean by mud, oil dirties, put lubricating oil is put in the crankcase, and adopt the rust and corrosion protection method.

how to deal with pit pump flow instability?

a slurry pit pump flow rate of the unstable reason to roughly the following:

1, the seal ring or impeller wear can also lead to severe slurry pit water pump flow instability, should inspect and replace worn sealing ring and the impeller.

2, bottom valve into the depth of water lack, lead to pumping air into the, should according to the slurry pit pump suction adjust the depth of the bottom valve.

3, pipeline leak may be there is air in the pump body, at this point in time will discharge the air in the pipeline.

4, suction pipe or bottom valve leakage, or perhaps they're inlet blockage, need to check the suction pipe and the bottom valve leakage air and plug in time, perhaps pack inlet in silt or plugs.

5, low voltage led to the decrease of the slurry pit pump rotation speed, the lack of slurry pit type pump, then check the power supply voltage and adjust in time.

6, if the slurry pit pump normal operation over a period of time, resumed normal operation after a period of time still appear this kind of problem, mostly due to slurry or other sundries are suction tube, at this time should be completely clean up before the pool and the suction pipe, reducing elbow length, under may increase mixing plant to reduce slurry settlement.
