Abstract
Description
Technical Field
[0001] The utility model belongs to the field of water pumps, and particularly relates to a vibration-reducing and noise-reducing pipeline pump. Background Art
[0002] A pipeline pump is a type of single-suction, single-stage or multi-stage centrifugal pump with a vertical structure. Because its inlet and outlet are in the same straight line and have the same inlet and outlet diameters, it resembles a section of pipe and can be installed at any position in the pipe, hence the name pipeline pump. Pipeline pumps will generate vibration and noise during use, which may cause damage to the inside of the pump body. Summary of the Invention
[0003] The purpose of the utility model is to provide a vibration-reducing and noise-reducing pipeline pump in response to the above-mentioned problems existing in the prior art.
[0004] The objectives of the present utility model can be achieved through the following technical solutions: A vibration-damping and noise-reducing pipeline pump, comprising a pump body, a motor for driving a water pump, and a base for supporting and fixing the water pump, characterized in that four connecting beam support seats in the form of rectangular protrusions are arranged under the base, an elastic element with an elastic reset function is arranged inside the connecting beam support seat, a circular counterweight block is arranged inside the base, four grooves are opened on the circular counterweight block, a connecting beam with a circular end is arranged between the groove walls corresponding to the grooves, the connecting beam is connected to the circular counterweight block through a connecting rod, and the other end of the connecting beam is provided with a connecting portion for connecting to the connecting beam support seat.
[0005] In the above-mentioned vibration-damping and noise-reducing pipeline pump, a connecting portion is also provided at the lower end of the circular counterweight block, which is longer than the connecting portion on the connecting beam. A circular counterweight block support seat is provided at the lower end of the connecting portion at the lower end of the circular counterweight block, which is longer than the connecting beam support seat, and an elastic element is provided inside the circular counterweight block support seat.
[0006] In the above-mentioned vibration-reducing and noise-reducing pipeline pump, a ceramic plate for reducing noise is provided on the inner wall of the motor.
[0007] Compared with the existing technology, this vibration-damping and noise-reducing pipeline pump will transmit the vibration force generated during use to the connecting part and the connecting beam through the elastic element in the connecting beam support seat, and finally transmit the force to the circular counterweight block, so that the circular counterweight block slides up and down to offset the force, effectively reducing the vibration of the pipeline pump. The ceramic plate can reduce the noise generated when the motor is operating. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0013] like Figure 1 、 Figure 2 、 Figure 3 As shown, the vibration-damping and noise-reducing pipeline pump includes a pump body 1, a motor 2 for driving the water pump, and a base 3 for supporting and fixing the water pump. Four connecting beam support seats 4 in the form of rectangular protrusions are arranged under the base 3, and a connecting beam support seat 4 is arranged inside the connecting beam support seat 4. An elastic element 5 with an elastic reset function is arranged inside the connecting beam support seat 4. A circular counterweight block 6 is arranged in the base 3, and four grooves 7 are opened on the circular counterweight block 6. A connecting beam 8 with a circular end is arranged between the groove walls corresponding to the grooves. The connecting beam 8 is connected to the circular counterweight block 6 through a connecting rod 9, and the other end of the connecting beam 8 is provided with a connecting portion 10 for connecting to the connecting beam support seat 4.
[0014] The circular counterweight 6 is also provided with a connecting portion 10 at the lower end, which is longer than the connecting portion 10 on the connecting beam 8. The lower end of the connecting portion 10 at the lower end of the circular counterweight 6 is provided with a circular counterweight support seat 11, which is longer than the connecting beam support seat 4. An elastic element 5 is provided inside the circular counterweight support seat 11. After the vibration reduction and noise reduction pipeline pump is placed, the pipeline pump is turned on. At this time, the pump body 1 vibrates, causing the body to shake, and the connecting beam support seat 4 moves upward, generating a corresponding thrust through the elastic element 5, pushing the connecting portion 10 upward. At this time, the connecting beam 8 swings up and down through the connecting rod 9, and the force is transmitted to the circular counterweight 6. The circular counterweight 6 swings up and down, so that the force is transmitted to the connecting portion 10 at the lower end of the circular counterweight 6, causing the connecting portion 10 at the lower end of the circular counterweight 6 to swing up and down. The generated force and the elastic element 5 inside the circular counterweight support seat 11 offset each other, thereby reducing the vibration of the pipeline pump.
[0015] A noise-reducing ceramic plate 12 is provided on the inner wall of the motor 2 to reduce the noise generated during the operation of the motor 2 .
[0016] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
[0017] Although this document frequently uses terms such as pump body 1, motor 2, base 3, connecting beam support 4, elastic element 5, circular counterweight 6, channel 7, connecting beam 8, connecting rod 9, connecting portion 10, circular counterweight support 11, and ceramic plate 12, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
