The working condition of the submersible pump is that the pump and the motor are submerged in the water together, and after the pump is energized, the pressurized water is guided by the outlet pipe. The outlet of the submersible pump is provided with a circular bend to buffer the resistance of the water. Changjia pump industry analysis submersible pump and shore with conventional horizontal, vertical pump is not the same, compared with them, submersible pump mainly reflected the advantages are:
1. Compact structure and small volume. Submersible pump operation needs all the potential water inside, there is no need to add additional workshop, so there is no need to build a special pump room to install them, can save a lot of economic expenses;
2. Easy operation, installation and maintenance. Submersible pump dives into the water, the installation position space is large, unrestricted, the weight of a little larger submersible pump is equipped with an automatic lifting coupling device, the movement is very convenient;
3. Able to work stably for a long time. Submersible pump shaft structure is special, pump and motor is the same shaft, shaft size is short, the weight of the rotor components is also light, the work time does not have to bear much axial force, life is higher than other pumps;
4. Because the submersible pump works under the water, it is completely closed, there will be no cavitation damage to the pump, and there is no need to inject water, very convenient;
5. The vibration noise of the submersible pump is almost no, the temperature rise of the unit is very small, and there is no need to consider cooling and cooling in the water;
Due to the excellent performance of submersible pump, it is widely used in domestic sewage discharge, factory sewage discharge, mine sewage discharge, water conservancy engineering and other fields.
