Description

Technical Field

[0001] This utility model relates to the field of submersible hot water motor technology, specifically to an ultra-high temperature submersible hot water motor. Background Technology

[0002] Ultra-high temperature submersible hot water motors are motors used underwater, typically directly connected to a pump and operating in the water. They are heat-resistant and can operate normally in water up to 120 degrees Celsius.12 These motors are widely used in applications such as extracting underground hot spring water, supplying hot water to bathhouses, and reusing waste hot water from factory boilers. However, existing submersible hot water motors, due to prolonged exposure to hot water and poor sealing, are prone to internal liquid ingress. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, an ultra-high temperature submersible hot water motor is provided to solve the problem that existing submersible hot water motors are prone to liquid ingress due to poor sealing when exposed to hot water for extended periods.

[0004] To achieve the above objectives, an ultra-high temperature submersible hot water motor is provided, comprising: a submersible hot water motor body, wherein a base is welded to the lower surface of the submersible hot water motor body.

[0005] The upper end of the submersible hot water motor body is connected to the rotor through an upper mechanical seal. The lower end of the rotor is connected to the inner wall of the submersible hot water motor body through a lower mechanical seal. The outer side of the rotor is provided with a stator and stator windings. A filling liquid channel is opened between the inner wall of the submersible hot water motor body and the stator windings. The filling liquid channel is distributed around the outer end of the rotor.

[0006] Furthermore, a sealing cover is tightly fixed to the upper end face of the submersible hot water motor body by fastening studs, and a drive shaft is installed inside the sealing cover.

[0007] Furthermore, a sealing bottom cover is fixedly sealed on the lower end face of the submersible hot water motor body; and the base is located on the lower surface of the sealing bottom cover, with a rotor connected to the lower end of the drive shaft.

[0008] Furthermore, a gravity balance seat is connected to the lower end of the rotor; and the gravity balance seat is located at the lower end of the lower mechanical seal.

[0009] Furthermore, a rubber adjusting bladder is provided inside the bottom of the submersible hot water motor body, and an air bladder inflation nozzle is connected to the lower end of the rubber adjusting bladder; and the air bladder inflation nozzle is sealed through the surface of the sealing bottom cover.

[0010] Furthermore, the lower end of the filling fluid channel is connected to the outer cavity of the rubber adjustment bladder.

[0011] The beneficial effects of this utility model are as follows: the ultra-high temperature submerged hot water motor of this utility model utilizes the filling liquid in the filling liquid cavity, which is located inside the motor housing and outside the rotor, stator, and stator windings. Through the pressure of the filling liquid in the filling liquid cavity, the contact area and pressure difference between the sealing components and internal parts of the submerged hot water motor create a sealing effect, achieving the effect of fluid sealing inside the ultra-high temperature submerged hot water motor. This prevents leakage inside the ultra-high temperature submerged hot water motor, enhances the sealing performance of the ultra-high temperature submerged hot water motor, and can effectively absorb and buffer the vibration and impact generated during motor operation, thereby improving the operational stability of the ultra-high temperature submerged hot water motor.

[0016] Reference Figures 1 to 3 As shown, this utility model provides an ultra-high temperature submersible hot water motor, including: a submersible hot water motor body 1, and a base 11 welded to the lower surface of the submersible hot water motor body 1.

[0017] The upper end of the submersible hot water motor body 1 is connected to the rotor 2 via the upper mechanical seal 22. The lower end of the rotor 2 is connected to the inner wall of the submersible hot water motor body 1 via the lower mechanical seal 23. The outer side of the rotor 2 is provided with a stator 3 and a stator winding 4. A filling liquid channel 15 is opened between the inner wall of the submersible hot water motor body 1 and the stator winding 4. The filling liquid channel 15 is distributed around the outer end of the rotor 2.

[0018] The submersible hot water motor body 1 uses the pressure of the filling liquid in the filling liquid cavity 15 to create a sealing effect through the contact area and pressure difference between the upper and lower sealing components and internal parts such as the rotor 2 and stator 3. This achieves the effect of fluid sealing inside the ultra-high temperature submersible hot water motor, preventing leakage inside the ultra-high temperature submersible hot water motor, enhancing the sealing performance of the ultra-high temperature submersible hot water motor, and effectively absorbing and buffering the vibration and impact generated during motor operation, thereby improving the operational stability of the ultra-high temperature submersible hot water motor.

[0019] In this embodiment, a sealing cover 12 is tightly fixed to the upper end face of the submersible hot water motor body 1 by fastening studs 13, and a drive shaft 21 is installed inside the sealing cover 12. A sealing bottom cover 14 is sealed and fixed to the lower end face of the submersible hot water motor body 1; and the base 11 is located on the lower surface of the sealing bottom cover 14. The lower end of the drive shaft 21 is connected to the rotor 2. The lower end of the rotor 2 is connected to the gravity balance seat 24; and the gravity balance seat 24 is located at the lower end of the lower mechanical seal 23.

[0020] In a preferred embodiment, the sealing top cover 12 and the sealing bottom cover 14 form the upper and lower sealing components of the submersible hot water motor body 1, preventing the ingress of external liquids. The stator 3 of the submersible hot water motor body 1 is composed of water-resistant insulated wire windings, providing excellent insulation. The rotor 2 is typically composed of copper and aluminum bars, isolated by insulating material to form a conductive circuit. Sealing devices are provided between the rotor 2, stator 3, and stator windings 4 and the filling liquid cavity 15 to prevent the filling liquid from entering the internal parts of the motor. The gravity balance seat 24 facilitates maintaining the rotational balance of the rotor 2. The drive shaft 21 is used for assembly and connection with the pump body.

[0021] In this embodiment, a rubber adjustment bladder 5 is provided inside the bottom of the submersible hot water motor body 1, and an airbag inflation nozzle 51 is connected to the lower end of the rubber adjustment bladder 5; and the airbag inflation nozzle 51 is sealed through the surface of the sealing bottom cover 14.

[0022] In a preferred embodiment, the rubber regulating bladder 5 is used to balance the pressure between the water and the inner cavity of the submersible hot water motor body 1, adapting to thermal expansion and contraction and water level changes. The air inflation nozzle 51 facilitates inflation of the rubber regulating bladder 5, ensuring the balanced regulating effect of the rubber regulating bladder 5.

[0023] In this embodiment, the lower end of the filling fluid cavity 15 is connected to the outer cavity of the rubber adjustment bladder 5.

[0024] As a preferred embodiment, the filling fluid channel 15 facilitates the flow of the motor filling fluid, thereby reducing internal friction within the motor (see attached diagram). Figure 2(The arrow indicates the direction of the motor filling fluid flow). Through the dynamic flow of the filling fluid in the filling fluid cavity 15, the contact area and pressure difference between the seals and internal parts of the submersible hot water motor body 1 create a sealing effect, achieving the effect of fluid sealing inside the ultra-high temperature submersible hot water motor. This prevents leakage inside the ultra-high temperature submersible hot water motor, enhances the sealing performance of the ultra-high temperature submersible hot water motor, and effectively absorbs and buffers the vibration and impact generated during motor operation, thereby improving the operational stability of the ultra-high temperature submersible hot water motor.

[0025] This invention relates to an ultra-high temperature submersible hot water motor, which effectively solves the problem of poor sealing and internal liquid ingress in existing submersible hot water motors that are constantly immersed in hot water. It achieves a fluid sealing effect on the inside of the ultra-high temperature submersible hot water motor, preventing leakage and enhancing its sealing performance. At the same time, it can effectively absorb and buffer the vibration and impact generated during motor operation, improving the operational stability of the ultra-high temperature submersible hot water motor. It is suitable for ultra-high temperature submersible hot water motors.
