How to maintain and service drainage pumps

How to maintain and repair the sewage pump? According to the model specifications and installation sites, there are some differences in the details of maintenance, but on the whole is to regularly check the performance of sewage pumps and each component intact, proper maintenance can greatly extend the life of the pump and maintain stable performance, related matters can be referred to the following content brought by the pump industry.

About how to maintain and maintenance of sewage pumps, according to the length of use and working conditions to carry out regular maintenance, generally every 500 hours to replace the lubricating oil, the first replacement time need to be reduced by half, if the working hours can not reach, then about half a year to carry out the necessary maintenance and maintenance, the relevant operating rules are as follows.

1, check the appearance of the pump body, try to ensure that the appearance of neat and clean and paint is not off, signs and nameplates are clear.

2, check the seal of the sewage pump, if it is a ground-driven pump, check whether the packing is good, to ensure that there is no seepage and overflow of water, if it is a submersible sewage pump, check whether the motor winding has moisture.

3, check the flexibility of operation, you can manually pan to confirm that there is no jamming, the pump shaft and motor shaft are located in the same centre line, the fastening bolts of the machine base are not rusted and not loose.

4, check the integrity of important accessories, mainly to confirm that the valve is flexible in opening and closing, no blockage and jamming, can be tightly closed, and there is no leakage inside or outside.

5, The pressure gauge can work normally, the index is accurate and the dial is clear, and there is no water seepage at the gauge valve and connection.

6, The operating parameters are up to standard, there is no drop in flow or abnormal pressure.

7, The motor is in good condition, the current and voltage need to be measured to ensure that there are no abnormalities.

8, Whether dismantled or repaired, in order to ensure the reliability of the seal, it must first be tested by 0.2MPa gas-tight test before use in water.

9, regularly check the sealing ring between the impeller and the pump body to avoid damage to affect the performance of the pump, and to check the insulation resistance between the electric pump winding and the casing.

Above, the introduction of sewage pumps how to maintenance and maintenance, taking into account the actual working conditions are complex and changeable, if you encounter other difficult problems when using the pump, you can directly to zhaoquan screw pump industry to seek professional technical support.
