Problems solved by technology

[0002] At present, most of the existing ordinary oil-immersed motors have excellent sealing performance, but the problem that follows is that the heat dissipation performance inside the fuselage is very poor. For some hot weather areas, these water pump motors are often due to the The internal heat dissipates, causing the internal temperature of the fuselage to be too high, and the normal operation of the fuselage is seriously affected. The service life of the water pump motor is also very short, and if there is oil leakage, it will seriously affect the ecological environment.

Embodiment 1

[0020] Example 1: as figure 1 As shown, a motor for a water pump includes a casing 1, a rotor assembly 2, a shielding sleeve 3, an upper bearing seat 4, a lower bearing seat 5, an upper end cover 6 and a lower end cover 7; The rotor shaft 21, the rotor 22 sleeved on the rotor shaft 21 and the magnetic steel sleeve 23 in the casing 1; the upper bearing seat 4 is arranged on the upper end of the upper end cover 6, and the lower bearing seat 5 is arranged on the lower end cover 7, and a cavity 8 is formed between the casing 1, the upper end cover 6 and the lower end cover 7, the cavity 8 includes a stator cavity 81 and a rotor cavity 82; the shielding sleeve 3 is sleeved on the rotor Inside the cavity 82, the shielding sleeve 3 is sleeved on the outside of the rotor assembly 2; the shielding sleeve 3 is formed with an accommodating cavity 31 filled with clean water and used for heat dissipation.

[0021] The motor of this technical solution is a shielded motor. The stator adopts...

Embodiment 2

[0038] Embodiment 2: as Figure 2-3 As shown, this embodiment is basically the same as the first embodiment, the difference is that a cavity 92 is formed in the side wall 93 of the sealing cavity 91, and a plurality of water pipes penetrating the cavity 92 are arranged on the side wall 93 94. One end of the water passage pipe 94 is located outside the side wall 93, and the other end is located in the sealed cavity 91. At least one sand-proof filter layer 95 is arranged in the water passage pipe 94.

[0039] The arrangement of the water pipe 94 in this technical solution makes the inside of the motor have good ventilation performance, and the heat generated by the motor during operation can be effectively discharged, which solves the problem that the internal heat of the motor cannot be discharged, and the normal operation of the motor is seriously affected by the high internal temperature. In addition, the sand-proof filter layer 95 in the water pipe 94 can prevent the sand an...

Abstract

The invention belongs to the technical field of a water pump, and particularly relates to an electric motor for the water pump. The electric motor comprises a machine shell, a rotor subassembly, a shielding sleeve, an upper bearing seat, a lower bearing seat, an upper end cover and a lower end cover, wherein the rotor subassembly comprises a rotor shaft penetrating in the machine shell, a rotor sleeved on the rotor shaft, and a magnetic steel sleeve; the upper bearing seat is disposed on an upper end of the upper end cover; the lower bearing seat is disposed on a lower end of the lower end cover; a cavity body is formed among the machine shell, the upper end cover and the lower end cover; the cavity body comprises a stator cavity and a rotor cavity; the shielding sleeve is sleeved in the rotor cavity and on an outer side of the rotor subassembly; and an accommodating cavity filled with clear water and used for dissipating heat is formed in the shielding sleeve. An objective of the invention is to provide the electric motor for the water pump with stable structure, good heat dissipation effect and environment-friendliness.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a motor used for water pumps. Background technique [0002] At present, most of the existing ordinary oil-immersed motors have excellent sealing performance, but the subsequent problem is that the heat dissipation performance inside the body is very poor. For some areas with hot weather, these water pump motors are often caused by the body The internal heat dissipates, causing the internal temperature of the fuselage to be too high, and the normal operation of the fuselage is seriously affected. The service life of the water pump motor is also very short, and if there is oil leakage, it will seriously affect the ecological environment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a motor for water pump with stable structure, good heat dissipation effect and environmental protection. [0004] The purpose of the present invention is ac...
