Embodiment Construction

[0029] Such as Figure 1 to Figure 5 As shown, it is a water-cooled canned pump of the present invention. The canned pump includes a casing 1 and a pump body 2. One end of the casing 1 is fixedly connected to the pump body 2 through a positioning connector 12, and the other end of the casing 1 is provided with an end cover. 36. The first sealing ring 23 and the second sealing ring 38 are respectively arranged between the housing 1 and the positioning connector 12 and the end cover 36. The first sealing ring 23 and the second sealing ring 38 can effectively prevent the housing 1 from Leakage occurs at the connection part, which improves the safety of the canned pump. The inside of the casing 1 is provided with a stator 19 and the rotor, and the bottom of the pump body 2 and casing 1 is provided with a base 3. The pump body 2 and casing 1 pass through the support frame. 13 is fixedly connected to the top surface of the base 3, the pump body 2 is provided with a liquid inlet flan...

Abstract

The invention discloses a water-cooled canned pump. The water-cooled canned pump comprises a shell and a pump body. One end of the shell is fixedly connected with the pump body through a positioning connecting piece. The other end of the shell is provided with an end cover. Stators and rotors are arranged in the shell. A cooling water driver is arranged on the top face of the shell and connected to the portion, close to a liquid outflow flange plate, of the pump body through a water conveying pipe. A liquid chamber and a vacuum chamber are formed in the shell. The liquid chamber is located in the center of the vacuum chamber. The liquid chamber and the vacuum chamber are separated through a shielding film. The stators are located in the vacuum chamber. The rotors are located in the liquid chamber. A buffering device is arranged in a base. The water-cooled canned pump is simple in structure and high in practicality; the difficulty of the manufacturing process of the canned pump is lowered, maintenance cost is reduced, and the canned pump is more convenient to mount and dismount; and the main rotor and the auxiliary rotors are used in cooperation, the working efficiency of the rotors can be effectively improved, and resistance generated due to gaps between the stators and the rotors is offset.

Description

technical field [0001] The invention relates to a water-cooled canned pump. Background technique [0002] The working principle of the canned pump is the same as that of the centrifugal pump. The centrifugal force is generated by the rotation of the impeller, which makes the liquid in the impeller separate from the impeller, transforms the velocity energy into pressure energy, and plays the role of transporting the medium. By connecting the rotor and the impeller with a shaft, and separating the coils of the stator and rotor from the conveying medium with a thin layer of shielding sleeve, the dynamic seal is converted into a static seal, and the flow is made between the stator and the rotor by the pressure difference. The medium forms a circulation, which cools the motor and the shaft and lubricates the bearings. [0003] Since the pump body is integrally formed, although there will be no leakage, it is very difficult to manufacture the canned pump, and the process is compl...
