Winter submersible sewage pump maintenance

Winter submersible sewage pump maintenance attention to what? Winter diving pump  step is what? Winter submersible sewage pump how to maintain?

Winter wind howling, we are very concerned about the winter problem: how to place the winter sewage submersible sewage pump; has been plaguing everyone. Here, Shanghai Weihu pump sewage pump small series will be how to properly handle the sewage pump winter ice concrete operation practices to share to you.

1. If the submersible sewage pump icing, use hot water or boiling water into the submerged sewage pump to internalize the ice. Or heating the submersible sewage pump housing.

2. The submersible sewage pump placed in a room temperature environment, can be more than zero.

3. Use of submersible sewage pump. The insulation layer by adding steam or hot water to prevent submersible sewage pump freezing.

4. The use of non-self-priming centrifugal pump, the use of water can be added only when the submersible sewage pump to avoid icing.

5. The submersible sewage pump within the water emptying, add water when used. To prevent submersible sewage pump freezing freezing submersible sewage pump.

Submersible sewage pump routine maintenance:

1. Drainage sewage pump is disabled, it is necessary to put away the submersible sewage pump and pipe the remaining water, and the external soil clean, so as not to freeze on the frozen water after the pump body and water pipe burst.

2. Submersible sewage pump bottom valve, elbow and other cast iron parts, wire brushes 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 Local preservation

3. Belt drive, remove the belt with warm water, dry and dry after cleaning, dry place, no direct sunlight, and do not store in a place of oil, corrosive substances 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 the submersible sewage pump impeller has cracks or holes, impeller fixing 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. Repair or replace the pump shaft which is bent or worn seriously, otherwise it will cause the unbalance of the rotor and the wear of the relevant parts.

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 wrap, put away, so as not to rust or loss.

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