Feature analysis 1. Compact structure, small footprint. Submersible sewage pump submerged in liquid work, so it can be installed directly in the cesspool, no need to build a special pump room for the installation of pumps and machines, can save a lot of land and infrastructure costs.
2. Easy to install and maintain. Small submersible sewage pumps can be installed by themselves, and large submersible sewage pumps are generally equipped with automatic coupling devices for automatic installation, which is quite convenient for installation and maintenance.
3. Long continuous running time. Because of the coaxial pump and motor, the shaft is short, the weight of rotating parts is light, so the load on the bearing (radial) is relatively small, and the life expectancy is much longer than that of general pumps.
4. There is no problem of cavitation damage and irrigation and diversion of water, etc. Especially the latter point brings great convenience to the operator.
5. Small vibration noise, low motor temperature rise. Note: 1. stainless steel submersible pump if used for pumping thicker and more viscous slurry, the pump cavity needs to be cleaned to prevent the pump from leaving sediment. 2. do not lift or hang the cable from the pump. 3. with automatic coupling device, the length of the guide rail needs to be determined (the standard length is 3M). 4. every three hundred to five hundred hours of use in the conventional state should be filled or replaced with oil in the oil chamber to improve the service life of the mechanical seal. After 3000 hours of regular pump operation, the pump needs to be disassembled for maintenance, and if necessary, replace the wearing parts that are no longer suitable.
