When facing a relatively large change in the average operating frequency of one or more main pumps, since the hardness of the rubber vibration damping or spring vibration damping structure is a fixed value and will not change with the change of the average operating frequency of one or more main pumps, the vibration damping and noise reduction effect of the above measures is poor.

[0040] In order to make the objectives, technical solutions, and advantages of this application clearer, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0041] In the following respective embodiments, taking the water supply unit Figure 1 shown as an example for illustration.

[0042] According to a first aspect, this application provides a vibration damping method for a water supply unit. This method is based on a water supply unit, which includes three main pumps 31, 32, 33, a base 21, a booster pump 41, and multiple vibration damping structures 11, 12, 13. Among them, each vibration damping structure 11, 12, 13 is installed under the base. A pressure sensor 061 is installed in the oil-gas chamber inside each vibration damping structure 11, 12, 13. Each vibration damping structure 11, 12, 13 is connected to its respective booster pump 41. The three main pumps 31, 32, 33 and the booster pump 41 operate independently. Among them, the three main pumps are used to boost the water supply for the external pipe network, and the booster pump 41 is used to adjust the pressure value of the oil-gas chamber inside each vibration damping structure 11, 12, 13.

[0043] Exemplarily, the above three main pumps 31, 32, 33 are all vertical booster pumps, the base 21, the booster pump 41, the three vibration damping structures 11, 12, 13, and three pressure relief valves 51, 52, 53 that are communicated with the internal chambers of the respective vibration damping structures 11, 12, 13.

[0044] In some embodiments, as Figure 2 shown, each vibration damping structure 11, 12, 13 includes an upper base structure 10, a lower base structure 30, and an annular locking cover 20. The lower base structure 30 is movably inserted into the upper base structure 10, and a chamber is formed between the two to fill with oil and gas to form a closed oil-gas unit for vibration damping. The lower base structure 30 is fixedly connected to the ground.

[0045] The annular locking cover 20 is installed at the connection between the upper base structure 10 and the lower base structure 30 to seal the oil and gas inside the chamber between the two.

[0046] In some embodiments, the upper layer of the oil-gas chamber is filled with gas, and the lower layer is filled with oil.

[0047] When the rotational speed of the booster pump 41 changes, both the volume and pressure value of the oil change, thereby changing the volume and pressure value of the gas in the upper layer of the oil-gas chamber.

[0048] In some embodiments, the upper base structure 10 is a hollow cylindrical cap-shaped structure. The upper surface of this structure is provided with a base installation hole for fixedly inserting and connecting with the base of the water supply unit above this structure. Specifically, as Figure 1As shown, a sealing ring 210 is provided inside the upper base structure.

[0049] The lower base structure 30 is a hollow cylindrical pocket structure, and the side of the structure is provided with an oil filling port 310 and an oil drain port 320; the oil filling port 310 is used to connect the internal chamber and the external booster pump 41. Specifically, Figure 1 As shown, a sealing ring 330 is provided inside the lower base structure.

[0050] like Figure 4 As shown, the above method includes:

[0051] S110: Calculating current vibration values ​​of one or more main pumps according to current power, average operating frequency and a set corresponding relationship of one or more main pumps;

[0052] S120: determining a target pressure value of the oil-gas chamber inside each vibration reduction structure according to the vibration value;

[0053] Specifically, the above-mentioned current power can be the average real-time output power of each main pump 31, 32, and 33. The set corresponding relationship needs to be obtained after prior testing by the test personnel. The specific process is: the test personnel first use the average real-time output power and average operating frequency of the three main pumps 31, 32, and 33 as independent variables, change the output frequency of each main pump 31, 32, and 33 through a frequency converter, and then use a vibration sensor to measure the vibration value of each main pump 31, 32, and 33 under different independent variables. Finally, the output pressure of the boost pump 41 is adjusted according to the vibration value obtained after processing to adjust the hardness of the vibration reduction structure 11, 12, and 13. Among them, the vibration value of each main pump 31, 32, and 33 is the displacement and acceleration corresponding to each main pump 31, 32, and 33.

[0054] Then, during the operation of the water supply unit, the main controller first calculates the current vibration value of each main pump 31, 32, 33 according to the current power, average operating frequency and the set corresponding relationship of each main pump 31, 32, 33. Then, according to the vibration value, the target pressure value of the oil and gas cavity inside each vibration reduction structure 11, 12, 13 is determined. Among them, the target pressure value is the internal pressure value that each vibration reduction structure 11, 12, 13 needs to change to reach.

[0055] For example, Figure 3Relationship table of the average real-time output power - operating frequency - pressure value of the booster pump 41 for the vertical booster pumps 31, 32, and 33 shown. For example, when the average real-time output power of the vertical booster pumps 31, 32, and 33 is 7.5 kW and the average operating frequency is 20 Hz, the pressure value of the booster pump 41 should be 13 pounds per square inch. At this time, the pressure values and their hardness inside each of the vibration damping structures 11, 12, and 13 have become a state matching the average real-time output power and average operating frequency of the vertical booster pumps 31, 32, and 33, improving the noise reduction effect of the vibration damping structures 11, 12, and 13.

[0056] S130: In response to the monitored value of the pressure sensor 061 of the target vibration damping structure deviating from the target pressure value, adjust the rotational speed of the booster pump 41 corresponding to the target vibration damping structure.

[0057] In some embodiments, in response to the monitored value of the pressure sensor 061 of the target vibration damping structure deviating from the target pressure value, adjusting the rotational speed of the booster pump 41 corresponding to the target vibration damping structure includes:

[0058] S210: Calculate the target rotational speed according to the difference between the detected value of the pressure sensor 061 of the target vibration damping structure and the target pressure value;

[0059] S220: Gradually adjust the rotational speed of the booster pump 41 of the target vibration damping structure to the target rotational speed.

[0060] Specifically, during the operation of the water supply unit, the target vibration damping structure is one or more of the vibration damping structures 11, 12, and 13 whose internal pressure value is greater than or less than the target pressure value. Then, the main controller calculates the target rotational speed according to the difference between the detected value of the pressure sensor 061 and the target pressure value. Among them, the target rotational speed is the rotational speed that the booster pump 41 needs to change to reach. Generally, the higher the rotational speed of the booster pump 41, the higher the internal pressure value of the vibration damping structures 11, 12, and 13.

[0061] In some embodiments, gradually adjusting the rotational speed of the booster pump 41 of the target vibration damping structure to the target rotational speed includes:

[0062] In response to the monitored value of the pressure sensor 061 of the target vibration structure being less than the target pressure value, gradually increase the rotational speed of the booster pump 41 of the target vibration damping structure to the target rotational speed to increase the internal liquid cavity pressure;

[0063] Or, in response to the monitored value of the pressure sensor 061 of the target vibration damping structure being greater than the target pressure value, gradually decrease the rotational speed of the booster pump 41 of the target vibration damping structure to the target rotational speed to reduce the internal liquid cavity pressure.

[0064] Specifically, the main controller can control the rotation speed of the booster pump 41 through the frequency converter. Among them, when the rotation speed of the booster pump 41 increases, the pressure value inside the damping structures 11, 12, and 13 increases. When the rotation speed of the booster pump 41 decreases, the pressure value inside the damping structures 11, 12, and 13 decreases.

[0065] In some embodiments, each of the damping structures 11, 12, and 13 is further equipped with a pressure relief valve 51, 52, and 53, and the method further includes:

[0066] In response to the monitoring value of the pressure sensor 061 of the target damping structure being greater than the target pressure value, the pressure relief valves 51, 52, and 53 of the target damping structure are opened to reduce the internal oil-gas cavity pressure.

[0067] Among them, as Figure 1 shown, the above pressure relief valves 51, 52, and 53 can be connected to the pipeline where the oil injection port 310 is located, or can be connected to the pipeline where the oil drain port 320 is located.

[0068] In some embodiments, each of the damping structures 11, 12, and 13 is provided with an oil drain port 320, and the oil drain port 320 communicates with the internal oil-gas cavity and the corresponding pressure relief valves 51, 52, and 53; opening the pressure relief valves 51, 52, and 53 of the target damping structure to reduce the internal oil-gas cavity pressure includes:

[0069] S310: Open the pressure relief valves 51, 52, and 53, and at the same time, monitor the real-time pressure value of the internal liquid cavity of the target damping structure through the pressure sensor 061;

[0070] S320: In response to the real-time pressure value reaching the target pressure value, close the pressure relief valves 51, 52, and 53.

[0071] It should be noted that for each step included in the damping method of the water supply unit provided in any of the above embodiments, unless there is a clear description in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of these steps can include multiple sub-steps or multiple stages, and these sub-steps or stages do not necessarily need to be executed at the same moment, but can be executed at different moments, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least a part of other steps or sub-steps or stages of other steps.

Each vibration damping structure 11, 12, 13 is connected to its respective booster pump 41. One or more main pumps and the booster pump 41 operate independently. Among them, one or more main pumps are used to boost the water supply for the external pipe network, and the booster pump 41 is used to adjust the pressure value of the oil-gas cavity inside the corresponding vibration damping structures 11, 12, 13. The system includes:
