Problems solved by technology
In recent years, although my country's electric pumps have made great progress, there are still some practical problems, which directly affect the economic and social benefits of the electric pump industry.
[0003] The traditional submersible electric pump is manufactured on the principle of three-phase asynchronous motor. This product is currently on the market. Its main problems lie in the following aspects: 1. The axial force cannot be solved, it is the thrust at the bottom of the motor However, the rapid wear of the thrust plate makes the motor unusable, especially on high-lift submersible pumps.
2. Large volume and heavy weight, which is not conducive to user use
3. Difficult to manufacture, complex process, unstable product performance and high cost
4. The efficiency of the electric pump is low, the power factor is low, and it cannot reach the energy-saving products
5. It is impossible to adjust the running speed of the motor, and it cannot reach the full head work

The invention discloses a household waste water utilization system and particularly discloses a magnetic suspension permanent magnet submerged electric pump. According to the technical scheme, the magnetic suspension permanent magnet submerged electric pump comprises a magnetic suspension permanent magnet motor and a water pump. The magnetic suspension permanent magnet motor is connected with the water pump through a coupler. The magnetic suspension permanent magnet motor comprises a center shaft. A rotor is fixed to the center shaft. The rotor is sleeved with a stator. One end of the center shaft is connected with an axial force adjusting mechanism. The axial force adjusting mechanism comprises two pieces of parallel magnetic steel with the same magnetism. The household waste water utilization system has the advantages of being long in service life, small in size and high in efficiency.
