When the stainless steel submersible sewage pump is not needed for a long time, it should be cleaned and hung up in a naturally ventilated and dry place, and attention should be paid to cold prevention. If placed in water, run for 30 minutes every 15 days (polishing is not allowed) to test its performance and adaptability.
Replace the sealing ring:
After long-term use in wastewater materials, the gap between the fan impeller and the sealing ring will expand, resulting in a decrease in water pump flow and efficiency. The electric switch should be turned off, the centrifugal water pump should be lifted, the back cover should be removed, the sealing ring should be taken out, and the sealing ring should be matched according to the finished size of the centrifugal impeller mouth ring. The gap is generally around 0.5mm.
After a malfunction occurs in the operation of a stainless steel submersible sewage pump, if it still cannot be resolved according to the given troubleshooting method and the cause cannot be determined, do not dismantle or repair it without authorization. Instead, immediately seek professional personnel for maintenance. Check the insulation and fastening screws of the motor once a year. If the insulation of the motor decreases, please find a dedicated person to repair it. If the fastening screws are loose, please tighten them again.
The stainless steel submersible electric pump sewage pump has been introduced with an appropriate amount of car oil before leaving the factory for lubricating the machine seal. The equipment oil should be inspected once a year. Once water is found in the car oil, it should be drained first, the oil should be changed, the sealing gasket should be removed, and the oil plug should be tightened. After three weeks, it is necessary to conduct another inspection. If the car oil becomes emulsified again, the machine seal should undergo a safety check.
Analysis of Characteristics of Stainless Steel Submersible Electric Pump
1. The structure is compact and occupies a small total area. Submersible sewage pumps can be directly installed in wastewater tanks because they enter underwater operation, without the need to build a dedicated pump room for assembling pumps and machines, which can save a lot of new land and infrastructure costs.
2. Easy maintenance and installation. Small stainless steel submersible sewage pumps can be assembled by themselves, while large submersible sewage pumps are generally equipped with fully automatic coupling devices that can also be automatically downloaded, making installation and maintenance very convenient.
3. The continuous operation time is long. Due to the coaxial line between the pump and motor, the shaft of the sewage submersible pump is short and the weight of the rotating components is relatively light. Therefore, the load (axial) that can be borne by the rolling bearings is relatively small, and the service life is much longer than that of ordinary pumps.
4. There are no issues such as cavitation damage or irrigation channels, especially the latter point brings a lot of convenience to the operators.
5. Low vibration noise and low motor temperature rise.
That's all for the introduction of stainless steel submersible electric pumps today. Through the above explanation, we have learned some knowledge about it, which is convenient for our daily use. If you need this type of electric pump, you can contact our manufacturer. Choosing us will definitely satisfy you.
