Description

Technical Field

[0001] This utility model relates to the field of fiberglass impeller drive technology, specifically to a magnetically levitated fiberglass impeller coupling drive device. Background Technology

[0002] Fiberglass, scientifically known as fiber reinforced plastic, is a type of fiber-reinforced composite plastic. It generally refers to reinforced plastics made by reinforcing unsaturated polyester, epoxy resin, and phenolic resin matrices with glass fibers or their products as reinforcing materials. Due to its corrosion resistance, light weight, and high strength, fiberglass is often used as a raw material for making impellers.

[0003] In existing fluid machinery equipment using fiberglass impellers, the drive method has some shortcomings, affecting equipment performance and operating efficiency. Traditional drive methods mostly use shaft connection, driving the impeller to rotate through mechanical transmission. During long-term operation, severe mechanical wear will occur at the connection between the shaft and bearing, and between the shaft and impeller. For example, in the chemical industry, the medium may contain corrosive substances and particulate impurities, which accelerates the wear of the shaft and related components, not only shortening the service life of the equipment, but also potentially causing safety hazards such as leaks.

[0004] Mechanical connection methods are easily affected by external factors, such as equipment installation accuracy and vibration during operation, which can lead to shaft eccentricity and wobbling, thereby affecting the rotational stability of the impeller. This may cause uneven fluid flow, generate noise and vibration, and reduce the stability and reliability of equipment operation. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a magnetic levitation fiberglass impeller coupling drive device, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a magnetic levitation fiberglass impeller coupling drive device, comprising: a protective shell, a sensor assembly disposed at one end inside the protective shell, a magnetic levitation rotor assembly disposed in the middle of the protective shell, the magnetic levitation rotor assembly including a permanent magnet, a rotor core disposed in the middle of the permanent magnet, radial magnetic levitation bearings disposed at both ends of the magnetic levitation rotor assembly, and an axial magnetic levitation bearing disposed at the other end inside the protective shell.

[0008] Furthermore, a number of heat dissipation holes are evenly distributed at one end of the protective housing, and a power distribution box is fixedly connected to the top of the protective housing.

[0009] Furthermore, the radial magnetic levitation bearing includes a stator, which is fixedly connected to the inner wall of the protective housing, and several winding coils are uniformly fixedly connected inside the stator.

[0010] Furthermore, both ends of the rotor core are fixedly connected to a rotating shaft, which is made of ceramic material and has a protective bearing sleeved on its surface.

[0011] Furthermore, a thrust disk is fixedly connected to the surface of one end of the rotor core, and the thrust disk is located in the middle of the axial magnetic levitation bearing.

[0012] Furthermore, a limiting turntable is fixedly connected to the surface of the other end of the rotor core, and the limiting turntable is located on one side of the sensor assembly.

[0013] Furthermore, the sensor assembly includes a speed sensor and a displacement sensor. The speed sensor is located on the inner wall of the sensor assembly to detect the rotational speed of the shaft, and the displacement sensor is located on one side of the sensor assembly to detect the position of the limiting turntable.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. By using radial and axial magnetic levitation bearings, the rotor core is suspended in a levitating state during operation, achieving contactless drive of the shaft. This avoids mechanical wear caused by traditional mechanical connection methods, greatly extends the service life of the equipment, and reduces the safety risk of leakage due to wear.

[0016] 2. Through the configuration of the sensor components, an external microcontroller is connected to the sensor components during use. The displacement sensor monitors the position of the rotor core in real time. By detecting changes in the position of the limit turntable, it feeds back to the microcontroller. The microcontroller adjusts the current of the winding coil according to the feedback signal to maintain the stable suspension and precise rotation of the rotor core. This allows for real-time monitoring and adjustment of the rotor core's position and attitude, effectively resisting external interference, ensuring the stability of the impeller rotation, reducing noise and vibration, improving the reliability of equipment operation, and providing stable power for fluid transportation. The speed sensor measures the rotor core's rotational speed so that the microcontroller can adjust the drive frequency in real time according to actual working requirements to achieve speed regulation.

[0017] 3. By setting up a protective bearing, the protective bearing is sleeved on the surface of the rotating shaft during use. When the drive device starts or stops or suddenly loses power due to a malfunction, the levitation force fails and provides temporary support to the rotor core, thereby ensuring the safe operation of the drive device.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments. Example 1

[0029] Reference Figure 1-6The first embodiment of this utility model discloses a magnetic levitation fiberglass impeller coupling drive device, comprising: a protective housing 1, a sensor assembly 5 disposed at one end inside the protective housing 1, a magnetic levitation rotor assembly 3 disposed in the middle of the protective housing 1, the magnetic levitation rotor assembly 3 including a permanent magnet 301, a rotor core 302 disposed in the middle of the permanent magnet 301, radial magnetic levitation bearings 2 disposed at both ends of the magnetic levitation rotor assembly 3, and an axial magnetic levitation bearing 4 disposed at the other end inside the protective housing 1.

[0030] By setting up radial magnetic levitation bearing 2 and axial magnetic levitation bearing 4, the rotor core 302 is kept in a suspended state during use, realizing contactless drive of the rotating shaft. This avoids mechanical wear caused by traditional mechanical connection methods, greatly extends the service life of the equipment, and reduces the safety risk of leakage caused by wear. Example 2

[0031] Reference Figure 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0032] A plurality of heat dissipation holes 101 are evenly provided at one end of the protective housing 1. A power distribution box 102 is fixedly connected to the top of the protective housing 1. The radial magnetic levitation bearing 2 includes a stator 201, which is fixedly connected to the inner wall of the protective housing 1. A plurality of winding coils 202 are evenly fixedly connected inside the stator 201. A rotating shaft is fixedly connected to both ends of the rotor core 302. The rotating shaft is made of ceramic material, and a protective bearing 305 is sleeved on the surface of the rotating shaft.

[0033] By setting up the protective bearing 305, the protective bearing 305 is sleeved on the surface of the rotating shaft during use. When the drive device starts or stops or suddenly loses power due to a malfunction, the levitation force fails and provides temporary support to the rotor core 302, thereby ensuring the safe operation of the drive device.

[0034] A thrust disk 303 is fixedly connected to the surface of one end of the rotor core 302. The thrust disk 303 is located in the middle of the axial magnetic levitation bearing 4. A limit turntable 304 is fixedly connected to the surface of the other end of the rotor core 302. The limit turntable 304 is located on one side of the sensor assembly 5. The sensor assembly 5 includes a speed sensor 501 and a displacement sensor 502. The speed sensor 501 is located on the inner wall of the sensor assembly 5 to detect the rotational speed of the shaft. The displacement sensor 502 is located on one side of the sensor assembly 5 to detect the position of the limit turntable 304.

[0035] With the sensor assembly 5 in use, a microcontroller is connected to the sensor assembly 5. The displacement sensor 502 monitors the position of the rotor core 302 in real time. The displacement sensor 502 detects the displacement of the limit turntable 304 and sends a signal back to the microcontroller. The microcontroller adjusts the current of the winding coil 202 according to the feedback signal to keep the rotor core 302 stably suspended and precisely rotating. This allows for real-time monitoring and adjustment of the position and attitude of the rotor core 302, effectively resisting external interference, ensuring the stability of the impeller rotation, reducing noise and vibration, improving the reliability of equipment operation, and providing stable power for fluid transportation. The speed sensor 501 measures the speed of the rotor core 302 so that the microcontroller can adjust the drive frequency in real time according to actual working requirements to achieve speed regulation.

[0036] The remaining structure is the same as that in Example 1.

[0037] The workflow of this utility model is as follows:

[0038] First, the radial magnetic levitation bearing 2 and the axial magnetic levitation bearing 4 are energized to make the rotor core 302 levitate. Then, the magnetic levitation rotor assembly 3 is energized to make the rotor core 302 rotate. By setting the radial magnetic levitation bearing 2 and the axial magnetic levitation bearing 4, the rotor core 302 is levitated during use, realizing contactless drive of the shaft. This avoids mechanical wear caused by traditional mechanical connection methods, greatly extends the service life of the equipment, and reduces the safety risk of leakage caused by wear.

[0039] Secondly, through the setting of sensor component 5, when in use, sensor component 5 is connected to an external microcontroller. Displacement sensor 502 monitors the position of rotor core 302 in real time. Displacement sensor 502 detects the displacement of limit turntable 304 and feeds back a signal to microcontroller. Microcontroller adjusts the current of winding coil 202 according to the feedback signal to keep rotor core 302 stable and levitating and rotating accurately. Thus, it can monitor and adjust the position and attitude of rotor core 302 in real time, effectively resist external interference, ensure the stability of impeller rotation, reduce noise and vibration, improve the reliability of equipment operation, and provide stable power for fluid transportation. Speed ​​sensor 501 measures the speed of rotor core 302 so that microcontroller can adjust the drive frequency in real time according to actual working requirements to realize speed regulation function.

[0040] Finally, by setting up the protective bearing 305, when in use, the protective bearing 305 is sleeved on the surface of the rotating shaft. When the drive device starts or stops or suddenly loses power due to a malfunction, the levitation force fails and provides temporary support to the rotor core 302, thereby ensuring the safe operation of the drive device.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
