Description

Technical Field

[0001] The utility model relates to the field of booster pumps, in particular to a silent multi-stage booster pump. Background Art

[0002] A multi-stage booster pump is a device used to increase the pressure of a fluid, usually consisting of a multi-stage impeller or a multi-stage centrifugal pump. Each level of impeller or centrifugal pump increases the pressure of the fluid, and a multi-stage booster pump can achieve a higher outlet pressure through this cascade method.

[0003] The existing multi-stage booster pump sucks the fluid into the pump body through the suction pipe, pressurizes it, and then discharges it from the discharge pipe. However, since the booster pump will generate vibrations during operation, these vibrations will be transmitted to the surrounding equipment, causing noise and affecting the working environment.

[0004] Therefore, a silent multi-stage booster pump has been developed that can perform shock-absorbing treatment on the pump body to avoid noise caused by vibration of the pump body and improve the working environment. Utility Model Content

[0005] In order to overcome the shortcomings of existing multi-stage booster pumps that generate vibrations during operation, and these vibrations are transmitted to surrounding equipment, causing noise and affecting the working environment, the utility model provides a silent multi-stage booster pump that can perform shock-absorbing treatment on the pump body to avoid noise generated by vibration of the pump body and improve the working environment.

[0006] The technical solution of the utility model is: a silent multi-stage booster pump, comprising a base plate, a pump body, a water pipe, a joint and a shock absorbing mechanism, wherein the upper rear side of the base plate is connected to the pump body, the front side of the pump body is connected to the water pipe, the front side of the water pipe is connected to the joint, the joint is connected to the base plate, and the base plate is provided with a shock absorbing mechanism capable of shock absorption.

[0007] Furthermore, a flange is provided on the joint.

[0008] Furthermore, the shock-absorbing mechanism includes a mounting seat, a connecting column and a spring. The front and rear parts of the base plate are connected to left and right connecting columns by a damping sliding method. A mounting seat is connected between two adjacent connecting columns. Springs are connected between the connecting columns and the base plate. When the pump body vibrates during operation, the base plate is driven to move on the connecting columns, causing the spring to be squeezed and contracted and then rebound.

[0009] Furthermore, it also includes a sound insulation mechanism, which includes a fixed frame, a connecting rod and a sound insulation box. The front and rear sides of the bottom plate are connected to left and right fixed frames, a connecting rod is connected between two adjacent fixed frames, and a sound insulation box is slidably connected between the left and right parts of the connecting rod. When the pump body is running, the sliding sound insulation boxes are close to each other on the connecting rod.

[0010] Furthermore, a connection groove is provided on the sound insulation box.

[0011] Furthermore, it also includes a sound insulation board, and the inner side of the sound insulation box is connected to the sound insulation board, and the sound insulation board soundproofs the pump body.

[0012] The utility model has the following advantages: 1. The utility model supports the bottom plate by the mounting seat. When the pump body generates vibration during operation, the bottom plate is driven to move on the connecting column, so that the spring is squeezed and contracted and then rebounds, thereby achieving the effect of shock-absorbing the pump body, avoiding noise generated by pump body vibration, and improving the working environment.

[0013] 2. In the utility model, when the pump body is running, the sliding sound insulation boxes are closed together on the connecting rod, so that the sound insulation board can soundproof the pump body, thereby achieving the effect of soundproofing the pump body and reducing the noise generated when the pump body is running.

After the fluid is pressurized, it is delivered to the target position through the pump body 2. When the base plate 1 is placed in the working area of ​​the booster pump, the mounting seat 51 supports the base plate 1. When the pump body 2 vibrates during operation, the base plate 1 is driven to move on the connecting column 52, so that the spring 53 is squeezed and contracted and then rebounds, thereby achieving the effect of shock-absorbing treatment of the pump body 2, avoiding the vibration of the pump body 2 and generating noise, and improving the working environment.

[0024] By using the sound insulation mechanism 6 of the device, the pump body 2 can be soundproofed. The connecting rod 62 is supported by the fixing frame 61. When the pump body 2 is running, the sliding sound insulation box 63 is closed on the connecting rod 62, so that the sound insulation board 64 soundproofs the pump body 2, thereby achieving the effect of soundproofing the pump body 2 and reducing the noise generated when the pump body 2 is running.
