M type pump chamber and centrifugal pump with M type pump chamber

The present invention relates to a M-type pump chamber of a centrifugal pump, and more particularly to an M-type pump chamber in which a centrifugal pump having an M-shaped chamber is formed inside the chamber.

The current micropump is designed as a mechanical seal, which will cause wear due to mechanical operation, which will lead to shortened life of the seal. Once the time is long, water leakage will occur, causing the micro pump to malfunction.

When a micro-pump malfunctions, a water leak occurs, which may cause some electronic components inside the micro-pump to enter the water, causing the motor to burn out, and thus there is a safety concern, which will cause the micro-pump to have friction during operation to form a resistance, so that the micro-pump The pump generates excessive noise during operation and shortens the life, reducing the performance and reliability of the micropump.

Furthermore, the rotor of the micropump is assembled by magnets, blades, back cover and plastic casing. When the micropump is produced, the rotor is firstly injected into the plastic casing, and then the magnet is placed in the plastic casing. The sound wave welds the back cover, the manufacturing process is quite complicated, and the product consistency is poor. When the magnet is placed in the plastic case, the surface magnetic field of the rotor is weakened due to the influence of the plastic interlayer, and the efficiency of the rotor is lowered.

In addition, most of the magnets used in the rotors of the micro-pumps use sintered magnets or bonded magnets, and such magnets have a rough surface, low precision, and more impurities are generated during the manufacturing process, which is high in cost, high in noise, and long-term. Working in the water will cause rust and cause pollution.
