Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, and in particular to a pump structure with noise reduction effect. Background Technology

[0002] A vacuum pump is a device that uses mechanical, physical, and chemical methods to evacuate a container to obtain and maintain a vacuum. It is widely used in electronics, metallurgy, chemical engineering, food processing, machinery, pharmaceuticals, aerospace, and other fields. In practical applications, pump structures with noise reduction capabilities typically require the following technologies: 1. Pump body: Provides a structure to house and support other components; 2. Impeller or rotor: This is the key component that generates the suction effect, and it drives the gas by rotating. 3. Shaft and bearings: support and ensure the smooth rotation of the impeller or rotor.

[0003] Traditionally, the pump body and motor are connected by a coupling. When the motor is running, it will vibrate, which will cause relatively continuous and noisy noise. Moreover, long-term vibration may cause chronic damage to the motor output shaft. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides a pump structure with noise reduction effect, which solves the technical problem that the traditional pump body and motor are connected by a coupling, and the motor will vibrate when it runs, which will cause relatively continuous and noisy noise. Moreover, long-term vibration may also cause chronic damage to the motor output shaft.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pump structure with noise reduction effect includes a pump body. The side wall of the pump body is provided with a noise reduction silencing mechanism. The noise reduction mechanism includes a transmission pipe, a cylindrical helical spring, a rubber washer, an inner cylinder, a connecting cylinder, and a rubber ring. The transmission pipe is fixedly installed on the side wall of the pump body, the cylindrical helical spring is fixedly installed on the side wall of the transmission pipe, the rubber washer is fixedly installed on the side wall of the transmission pipe, the cylindrical helical spring and the rubber washer are fixedly installed inside the inner cylinder, the connecting cylinder is fixedly installed on the side wall of the transmission pipe, and the rubber ring is fixedly installed on the side wall of the connecting cylinder.

[0006] Preferably, an outer cylinder is fixedly installed on the side wall of the transmission pipeline, and a corrugated pipe is fixedly installed on the side wall of the outer cylinder.

[0007] Preferably, a triangular prism is fixedly installed inside the transmission pipeline, and a mounting base is fixedly installed at the bottom of the pump body.

[0008] Preferably, a sound-absorbing sleeve is fixedly installed on the top of the mounting base, and a damping rod is fixedly installed on the bottom of the mounting base.

[0009] Preferably, a mounting plate is fixedly installed on the side wall of the damping rod, and a base is fixedly installed on the bottom of the mounting plate.

[0010] Preferably, a rubber sheet is fixedly installed at the bottom of the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. During use, the silencing sleeve absorbs the noise generated by the pump body, reducing noise at its source. When the air blown out by the pump body passes through the transmission pipe, the transmission pipe will vibrate. The transmission pipe will transmit the vibration to the cylindrical helical spring and rubber gasket. The cylindrical helical spring and rubber gasket will reduce the noise generated by the vibration of the transmission pipe to the greatest extent. The inner cylinder sidewall is wrapped with an outer cylinder, which will further reduce the noise emitted. A corrugated pipe is set at the end of the outer cylinder. When the gas passes through the corrugated pipe, it can absorb the noise generated by vibration. When the gas passes through the triangular prism, the tip of the triangular prism can guide the fluid to a certain extent, making the fluid flow more smoothly, reducing local turbulence and eddies, and making the gas flow more steadily. This can effectively reduce the generation of vibration and noise, thereby achieving the function of noise reduction.

[0012] 2. When the pump body is running, the vibration generated by the pump body will be absorbed by the damping rod. When the weight of the pump body is uneven, the mounting plate will force the damping rod to be in the same plane. The base supports it, and the rubber sheet further reduces the vibration generated by the pump body, thereby achieving auxiliary noise reduction and increasing the stability of the operating device.

[0019] This application provides a pump structure with noise reduction effect, effectively solving the problem of traditional pumps connected to motors via couplings, where motor operation generates vibration, leading to continuous and noisy noise. Furthermore, prolonged vibration can cause chronic damage to the motor output shaft. In use, the noise-absorbing sleeve absorbs the noise generated by the pump body, reducing noise at its source. When the air blown out by the pump body passes through the transmission pipe, the transmission pipe vibrates, transmitting this vibration to the cylindrical helical spring and rubber gasket. The cylindrical helical spring and rubber gasket minimize the noise generated by the transmission pipe vibration. The inner cylinder sidewall is wrapped with an outer cylinder, which further reduces noise. To reduce noise, a bellows is installed at the end of the outer cylinder. When gas passes through the bellows, the noise generated by vibration is absorbed. When gas passes through the triangular prism, the tip of the prism can guide the fluid, making the fluid flow more smoothly and reducing local turbulence and eddies. This makes the gas flow more steadily, effectively reducing vibration and noise generation, thus achieving noise reduction. When the pump is running, the vibration generated by the pump will be absorbed by the damping rod. When the weight of the pump body is uneven, the mounting plate will force the damping rod to be on the same plane. The base supports it, and the rubber sheet further reduces the vibration generated by the pump body, thereby achieving auxiliary noise reduction while increasing the stability of the operating device. Example

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that in traditional pumps, the pump body and motor are connected by a coupling, and the motor vibrates during operation, resulting in continuous and noisy noise. Furthermore, prolonged vibration can cause chronic damage to the motor output shaft. The overall concept is as follows: A pump structure with noise reduction effect includes a pump body 11. A noise-reducing silencing mechanism is provided on the side wall of the pump body 11. The silencing mechanism includes a transmission pipe 15, a cylindrical helical spring 16, a rubber washer 17, an inner cylinder 18, a connecting cylinder 19, and a rubber ring 21. The transmission pipe 15 is fixedly installed on the side wall of the pump body 11, the cylindrical helical spring 16 is fixedly installed on the side wall of the transmission pipe 15, the rubber washer 17 is fixedly installed on the side wall of the transmission pipe 15, the cylindrical helical spring 16 and the rubber washer 17 are fixedly installed inside the inner cylinder 18, the connecting cylinder 19 is fixedly installed on the side wall of the transmission pipe 15, and the rubber ring 21 is fixedly installed... Installed on the side wall of the connecting cylinder 19, the silencing sleeve 23 absorbs the noise generated by the pump body 11 during use, reducing noise at its source. When the air blown out by the pump body 11 passes through the transmission pipe 15, the transmission pipe 15 will vibrate. The transmission pipe 15 transmits the vibration to the cylindrical helical spring 16 and the rubber washer 17. The cylindrical helical spring 16 and the rubber washer 17 will reduce the noise generated by the vibration of the transmission pipe 15 to the greatest extent. The inner cylinder 18 is wrapped with the outer cylinder 12 on its side wall, which will further reduce the noise. The outer cylinder 12 is provided with a bellows 13 at the end. When the gas passes through the bellows 13, it can absorb the noise generated by the vibration. When the gas passes through the triangular prism 14, the tip of the triangular prism 14 can play a certain guiding role for the fluid, making the fluid flow more smoothly, reducing local turbulence and eddies, and making the gas flow more steadily. This can effectively reduce the generation of vibration and noise, thereby achieving the function of noise reduction.

[0021] An outer cylinder 12 is fixedly installed on the side wall of the transmission pipeline 15, and a corrugated pipe 13 is fixedly installed on the side wall of the outer cylinder 12. A triangular prism 14 is fixedly installed inside the transmission pipeline 15. A mounting base 22 is fixedly installed at the bottom of the pump body 11. A sound-absorbing sleeve 23 is fixedly installed on the top of the mounting base 22. A damping rod 24 is fixedly installed at the bottom of the mounting base 22. A mounting plate 25 is fixedly installed on the side wall of the damping rod 24. A base 26 is fixedly installed at the bottom of the mounting plate 25. When the pump body 11 is running, the vibration generated by the pump body 11 will be absorbed by the damping rod 24. When the weight of the pump body 11 is uneven, the mounting plate 25 will force the damping rod 24 to be in the same plane. The base 26 supports it. The rubber sheet 27 further reduces the vibration generated by the operation of the pump body 11, thereby achieving auxiliary noise reduction and increasing the stability of the operating device.

[0022] A rubber sheet 27 is fixedly installed at the bottom of the base 26 to reduce vibration and increase the stability of the device.

[0023] To address the problems existing in the prior art, this utility model provides a pump structure with noise reduction effect. During use, the sound-absorbing sleeve 23 absorbs the noise generated by the pump body 11, reducing noise at its source. When the air blown out by the pump body 11 passes through the transmission pipe 15, the transmission pipe 15 vibrates. The transmission pipe 15 transmits this vibration to the cylindrical helical spring 16 and the rubber washer 17, which minimizes the noise generated by the vibration of the transmission pipe 15. The inner cylinder 18 has an outer cylinder 12 wrapped around its side wall, further reducing noise. A corrugated pipe 13 is provided at the end of the outer cylinder 12. When gas passes through the corrugated pipe 13... The vibration-generated noise can be absorbed. When the gas passes through the triangular prism 14, the tip of the triangular prism 14 can guide the fluid to a certain extent, making the fluid flow more smoothly, reducing local turbulence and eddies, and making the gas flow more steadily. This can effectively reduce the generation of vibration and noise, thereby achieving the function of noise reduction. When the pump body 11 is running, the vibration generated by the pump body 11 will be absorbed by the damping rod 24. When the weight of the pump body 11 is uneven, the mounting plate 25 will force the damping rod 24 to be in the same plane. The base 26 supports it, and the rubber sheet 27 further reduces the vibration generated by the operation of the pump body 11, thereby achieving auxiliary noise reduction while increasing the stability of the operating device.

[0024] Pump body 11: generates fluid transport power, and produces noise and vibration; Transmission pipe 15: transports fluid while generating vibration and transmitting noise; Cylindrical helical spring 16: absorbs vibration of transmission pipe 15 and reduces noise; Rubber gasket 17: Helps reduce noise generated by vibration of transmission pipe 15; Inner cylinder 18: Provides installation space for cylindrical helical spring 16 and rubber washer 17, and also helps reduce noise; Connecting cylinder 19: Connects related components; Rubber ring 21: provides sealing and cushioning; Outer tube 12: Further reduces noise transmission; Bellows 13: Absorbs vibration and noise generated when gas passes through; Triangular prism 14: guides the flow of fluid, allowing it to flow smoothly, reducing turbulence and eddies, and lowering vibration and noise; Mounting base 22: Supports and fixes pump body 11; Silencing sleeve 23: Absorbs the noise generated by the pump body 11, reducing noise at the source; Damping rod 24: Absorbs vibrations generated during pump body 11 operation; Mounting plate 25: Ensures that the damping rods 24 are on the same plane, guaranteeing stability; Base 26: Supports the entire device; Rubber sheet 27: Further reduces the vibration generated by the operation of pump body 11 and increases stability.

[0025] Working principle: The first step involves the silencing sleeve 23 absorbing the noise generated by the pump body 11 during use, reducing noise at its source. When the air blown out by the pump body 11 passes through the transmission pipe 15, the transmission pipe 15 vibrates, transmitting the vibration to the cylindrical helical spring 16 and rubber washer 17. The cylindrical helical spring 16 and rubber washer 17 minimize the noise generated by the vibration of the transmission pipe 15. The inner cylinder 18 is wrapped with the outer cylinder 12, which further reduces noise. A bellows 13 is installed at the end of the outer cylinder 12. When the gas passes through the bellows 13, it absorbs the noise generated by the vibration. When the gas passes through the triangular prism 14, the tip of the triangular prism 14 guides the fluid, making the fluid flow more smoothly, reducing local turbulence and eddies, and making the gas flow more steadily. This effectively reduces vibration and noise, thus achieving the noise reduction function.

[0026] The second step is that when the pump body 11 is running, the vibration generated by the pump body 11 will be absorbed by the damping rod 24. When the weight of the pump body 11 is uneven, the mounting plate 25 will force the damping rod 24 to be on the same plane. The base 26 supports it, and the rubber sheet 27 further reduces the vibration generated by the operation of the pump body 11, thereby achieving auxiliary noise reduction and increasing the stability of the operating device.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
