The said housing (11) has single or double fluid intakes and one fluid outlet (115). A coil (14) is fixed in the housing (11). Besides, the housing (11) has an impeller (12) inside, and the ring-shaped magnet (13) is attached on the impeller (12). The present invention can transport liquid state fluid and gaseous state fluid. With the design that ring-shaped magnet (13) is attached on the impeller (12), the fluid backflow capacity can be reduced substantially to increase the outlet pressure of the pump (1) and fluid capacity of outlet (115). Because the ring-shaped magnet (13) is attached on the impeller (12), the motor diameter is increased to raise the output torque and pump rotation speed to increase the global efficiency of the motor and pump to increase the fluid flow capacity. Moreover, the present invention provides a reduced global volume after combination of the pump and the motor. Furthermore, the heat generated during the motor operation can be dissipated by the fluid to increase the motor efficiency and life.

Description

1262249 V. INSTRUCTION DESCRIPTION ci) Technical Field of the Invention The present invention relates to a high-torque single- and double-suction centrifugal motor pump, and in particular to a fluid recirculation by a design of a ring magnet device on an impeller. Increase the pump outlet pressure and increase the torque, thereby increasing the overall efficiency of the pump. [Prior Art] Conventional centrifugal motor pumping structures generate magnetic energy by inputting electric energy from a coil on a stator, and interact with a magnet on the rotor to drive the pump #rotation to cause fluid to flow. In addition, the structure of the motor pump is the same as that of the motor fan, and the actuation method is the same. However, the conventional centrifugal motor pump has the following drawbacks: 1 · Please refer to the eighth figure. The conventional in-line motor pumping 3 design system adopts the stator, and the rotor is outside the transition. Due to the limitation of the space at the 32-axis shell of the fan blade body, the design of the motor 31 is limited to the torque output. Directly leading to the limitation of the pump speed, and the amount of fluid produced is also limited, and can not produce a larger amount of fluid. 2 • The conventional interpolated motor pumping 3 design system is an external transformation. The stator system of the external transformation 0 is composed of coils. 'The input of electric energy to generate magnetic energy' interacts with the magnet on the rotor to drive the pump to rotate. However, the externally-rotated motor is pumped with a built-in design of the stator and is placed in the shaft shell of the blade body 32. At the same time that the input power of the coil generates magnetic energy, the coil generates a high temperature, and the stator generates a high temperature, and the temperature cannot be high.

INSTRUCTIONS (2) Effectively dissipating, causing the motor pump to be prone to lower its efficiency and use of life due to high temperatures. 3 • The torque of the conventional in-line motor pump 3 is the same as that of a conventional motor such as a computer fan motor. If the torque is to be increased, the radius of the rotor of the motor 3 1 must be increased, and the space of the portion of the blade body 3 2 becomes smaller, resulting in a lower pumping efficiency. 4 · Please refer to the ninth figure. The conventional external motor pump 4 series mining motor 4 1 I· is designed to be separated from the pump 4 2 . This split design increases the depth of the overall motor pump 4, which limits the environment for small spaces and cannot be widely used. 5 · The structure of the conventional externally-mounted motor pump 4 series motor 4 1 and the pump 4 2 is separated, so that the combined space of the pump 4 2 and the motor 4 1 becomes larger, the stability thereof is lowered, and the torque is also It is the same as the traditional motor torque and can no longer be increased. j · Please refer to the tenth figure. The conventional motor pump 5 has a gap between the housing ύ 1 and the fan blade body 5 2 , so that the high pressure fluid at the outlet is easily returned to the inlet. SUMMARY OF THE INVENTION In view of the above, the present inventors have directed to various conventional motor pumps described above.
