Description

Technical Field

[0001] The utility model relates to a noise reduction device, in particular to a noise reduction device for a pump house. Background Art

[0002] A pump house is a key water supply facility for installing water pumps to provide a stable water source for industrial production, residential life, etc. It is commonly found in places with large water demands such as large enterprises, waterworks, mines, power plants, and residential areas. Its main function is to provide a suitable working environment for water pumps and their auxiliary equipment, and at the same time facilitate the daily maintenance of operation and management personnel. The structural types of pump houses are diverse, including fixed and mobile types. Fixed pump houses are further subdivided into sub-base type, dry chamber type, wet chamber type, and block base type. Scientifically designing a pump house not only helps to save construction costs, but also can extend the service life of equipment and ensure the safety and economy of operation.

[0003] However, noise will be generated during the operation of the pump house. The sources include but are not limited to internal friction of the water pump, motor noise, pipeline vibration, water hammer effect, design defects, improper fluid control, cavitation phenomenon, and echo effect. These noises include not only low-frequency vibration and mechanical friction sounds, but also water hammer sounds, etc., which have a negative impact on the surrounding environment and the health, work, and quality of life of personnel. Due to the complex noise sources in the pump house, it is difficult for existing pump house noise reduction devices to achieve ideal effects by relying solely on one noise reduction measure. A comprehensive noise reduction strategy must be adopted, combining sound absorption and vibration reduction measures, to effectively control noise pollution.

At the left part of both second valves 10, a pump set 11 is installed. The pump set 11 is used to adjust the rotation speed. Between the left ends of both pipelines 9, a water outlet pipe 13 is fixedly connected. At the lower part of the water outlet pipe 13, a third valve 12 is installed. At the center of the top of the water outlet pipe 13, a second pressure gauge 14 is installed. On the left part of the base 1, a U-shaped frame 15 is welded. Between the front and rear sides of the middle part of the U-shaped frame 15 and the pump set 11, a first spring 16 is provided. Between the front and rear sides of the middle part of the U-shaped frame 15 and the pump set 11, a damper 1601 is provided. The first spring 16 is respectively wound outside the corresponding damper 1601. The first spring 16 and the damper 1601 are used to weaken the vibration generated when the pump set 11 works. At the bottom of the base 1, a plurality of rubber cushion blocks 19 with a certain interval are provided. The rubber cushion blocks 19 are provided with a plurality of through holes. The rubber cushion blocks 19 are used to isolate the vibration. At the center of the front part of the steady-flow compensation tank 3, a controller 21 is installed. The pump set 11 is electrically connected to the controller 21.

[0022] As Figure 1 and Figure 2 shown in the figure, it further includes a sealing airbag 5. A sealing airbag 5 is fixedly connected to the first valve 4.

[0023] As Figure 1 , Figure 2 and Figure 5 shown in the figure, it further includes an insulating board 20. An insulating board 20 is slidably provided below the base 1. The insulating board 20 is provided with a plurality of rubber blocks.

[0024] As Figure 1 and Figure 2 shown in the figure, it further includes a second spring 17. Second springs 17 are provided around both the base 1 and the insulating board 20.

[0025] As Figure 1 , Figure 2 and Figure 3 shown in the figure, it further includes a clamping plate 18. A clamping plate 18 is provided between the base 1 and the insulating board 20. The clamping plate 18 is made of an organic fiber material with good sound absorption performance. A plurality of through holes are provided in the clamping plate 18.

[0026] When the pump house is in operation, noise will be generated. The sources include, but are not limited to, internal friction of the water pump, motor noise, pipeline vibration, water hammer effect, design defects, improper fluid control, cavitation, and echo effect. These noises have a negative impact on the surrounding environment and the health, work, and quality of life of personnel. Therefore, a noise reduction device for the pump house is needed. When this device needs to be used, first, connect the power supply of the device and prepare to start the noise reduction operation. The steady flow compensation tank 3 and the water supply tank 7 work together. When tap water enters the steady flow compensation tank 3 through the first valve 4, the sealed airbag 5 conducts sound insulation treatment on the first valve 4. The air in the steady flow compensation tank 3 is discharged through the internal vacuum eliminator to ensure the stable pressure of the steady flow compensation tank 3. After the tap water is full, the vacuum eliminator automatically closes to prevent external air from entering again. If the pressure of the pipeline 9 can meet the water pressure and water volume requirements, the tap water is then transported to the left part of the pipeline 9 through the water supply tank 7, and then directly supplies water to the left end of the pipeline 9 by opening the second valve 10 and the third valve 12. During the water supply process, the first spring 16 and the damper 1601 work together to effectively absorb the vibration generated during the operation of the pump unit 11 and reduce the transmission of mechanical noise to the surrounding environment. The rubber cushion block 19 is arranged at the bottom of the base 1 to further isolate the vibration and reduce the vibration noise transmitted through the ground. If the pressure of the tap water pipeline 9 cannot meet the water use requirements, the operation controller 21 gives a pump starting signal through the first pressure gauge 8 to start the pump unit 11. When the pump unit 11 supplies water, if the water volume of the tap water pipeline 9 is greater than the flow rate of the pump unit 11, the system maintains normal water supply. During the peak water use period, if the water volume of the tap water pipeline 9 is less than the flow rate of the pump unit 11, the water in the steady flow compensation tank 3 is adjusted as a supplementary water source to ensure normal water supply. The tap water flows through the pump unit 11 to the water outlet pipe 13, and finally, by observing the second pressure gauge 14, the operation controller 21 starts the pump unit 11 to adjust the water pressure and flow rate to reduce the water flow fluctuation, thereby achieving the effect of reducing the water flow impact sound.
