Maintenance of submersible sewage pump in winter

The cold wind howling, nowadays is late January, the winter we are very concerned about the problem: the winter ice how the pump; has been plaguing everyone.

Here, how to correctly handle the sewage pump winter ice concrete operation practices to share to you

1. If the pump is frozen, use hot water or boiling water to pump into the ice. Or heat the pump housing.

2. Place the pump in an ambient temperature environment. Below zero.

3. Use a downhole pump. The pump into the underground, the general underground pump deep from the ground, will not freeze.

4. The use of insulation-type pumps. Add the insulation to steam or hot water. To prevent the pump from freezing.

5. Using non-self-priming centrifugal pump. Use only when the water can be added to avoid freezing the pump.

6. The water within the pump emptying, add water when used. To prevent the freezing of water pump pump freezing.

Routine maintenance:

① self-suction sewage pump After the pump is disabled, to put all the water pumps and piping within the residual water, and the external soil clean, so as to avoid freezing water on the pump body and water pipe burst.

② water pump at the end of valve, elbow and other cast iron parts, wire brush should be the rust brush net, and then coated with anti-rust paint and then painted, to be dry and then into the engine room or storage room ventilated dry place to save

③ belt drive, remove the belt with warm water after the dry clean dry, hung in the absence of direct sunlight, and do not store in a place of oil, corrosive and smoke. In any case, do not make the belt stained with oil, diesel or gasoline and other oil substances, do not coated rosin and other viscous substances.

④ Check the ball bearings, such as wear within the jacket, Kuang move, ball wear or surface spots to be replaced. Do not need to replace the gasoline or kerosene can be used to clean the bearings, coated with butter, re-installed.

⑤ check self-suction sewage pump pump impeller whether there are cracks or holes, impeller nut is loose, if damaged should be repaired or replaced. If the impeller wear too much or has been broken, the general should replace the new impeller. Local damage can be welding, epoxy mortar can also be used to repair the impeller, impeller repair should be carried out after the static balance test. Check the impeller wear ring clearance, if more than the specified value, should be repaired or replaced.

⑥ bending or wear serious pump shaft, should be repaired or replaced, otherwise it will cause the rotor imbalance and related parts wear.

⑦ Remove the screws soaked in diesel oil brush with a wire brush clean, and coated with oil or butter, re-installed or wrapped with plastic sheeting put away, so as to avoid corrosion or loss.

Through the above sewage pump how to deal with and maintenance of winter learning, I believe we in this cold winter no longer have to worry about sewage pump can not work smoothly!
