Description

Technical Field

[0001] The present application relates to the technical field of compression pumps, and in particular to a silent pump control method. Background Art

[0002] Existing air compression pumps generate noise when in operation, and the noise is even more severe when a large flow rate is required. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a silent pump control method, which has the advantage of being able to reduce noise during use.

[0004] The above-mentioned purpose of this application is achieved through the following technical solutions:

[0005] A silent pump control method includes a compression pump and a silent box. The compression pump is arranged in the silent box. The compression pump includes a rotating shaft cavity. A silencer is provided on the side wall of the silent box. The silent box is also provided with an air inlet and an air outlet. A fan is provided in the silent box. The silent box is also provided with a temperature detection module, a noise detection module and a control module. When the speed of the compression pump increases, the control module obtains the data detected by the noise detection module and makes a judgment. If it does not meet the standard value, an abnormality notification is issued. The control module obtains the data detected by the temperature detection module after a preset time. If it is greater than the preset value, the control module controls the fan speed to increase.

[0006] By adopting the above technical solution, during use, due to the presence of the silent box, noise can be effectively blocked, thereby reducing noise during use. At the same time, by detecting noise and temperature, active heat dissipation is performed through the fan, which can achieve a good heat dissipation effect.

[0007] In a preferred example, the present application can be further configured as follows: a baffle is provided on the soundproof box, both the air outlet and the air inlet are provided with the said baffle, a driving member for driving the baffle to block the air outlet or the air inlet is also provided in the soundproof box, and a silencer is provided on the baffle.

[0008] By adopting the above technical solution, the presence of the shielding plate makes it possible to shield the air outlet and the air inlet as needed, thereby achieving a better soundproofing effect.

[0009] In a preferred example, the present application can be further configured as follows: the control module obtains the data detected by the temperature detection module after a preset time, and the control module drives the baffle to adjust the blocking area of ​​the air outlet or air inlet according to the temperature control driving member.

[0010] By adopting the above technical solution, the position of the shielding plate is adjusted according to the temperature, thereby achieving the goal of ensuring the heat dissipation effect while reducing noise.

[0011] In a preferred example, the present application can be further configured as follows: the control module obtains the data detected by the noise detection module and makes a judgment. If it is less than the standard value A, the control module obtains the data detected by the temperature detection module. If it is greater than the ambient temperature, the control module controls the driving member to move the baffle according to the temperature to cancel the obstruction of the air outlet and the air inlet.

[0012] By adopting the above technical solution, when the noise value is less than the standard data A and the detected temperature is greater than the ambient temperature, the air outlet and the air inlet are not blocked, thereby achieving the purpose of enhancing heat dissipation.

[0013] In a preferred example, the present application can be further configured as follows: when the detected temperature is equal to the ambient temperature, the control module controls the driving member to drive the baffle to move, blocking the air outlet and the air inlet with a preset area, and after a preset time, compares the temperature and blocks the preset area again. When the detected temperature is greater than the ambient temperature, blocking of the preset area is performed N times. When the detected temperature is greater than the ambient temperature, the control module controls the driving member to drive the baffle to move, and restores to the blocking area at N-1 times.

[0014] By adopting the above technical solution, that is, by adjusting the shielding areas of the air outlet and the air inlet multiple times, a balance point between heat dissipation and noise reduction can be achieved.

[0015] In a preferred example, the present application can be further configured as follows: the control module obtains the motor speed, and obtains the noise value corresponding to the current speed, the detection data of the noise detection module, if the noise is greater than the noise value corresponding to the current speed, obtains the temperature detected by the temperature detection module, and if the temperatures are all within the normal range, a fault notification is issued.

[0016] By adopting the above technical solution, when the noise does not match the current rotation speed, it indicates that a fault has occurred, and thus a fault notification is performed.

[0017] In a preferred example, the present application can be further configured as follows: the control module obtains temperature data and compares it with previous temperature data. If the temperature changes significantly, an abnormality notification is issued.

[0018] By adopting the above technical solution, when the temperature changes greatly, it indicates that there may be an abnormality, so an abnormality notification is performed.

[0019] In a preferred example, the present application can be further configured as follows: when the temperature drops, the control module analyzes the received noise, and if the target noise exists, a leakage notification is issued.

[0020] By adopting the above technical solution, when the temperature drops, it indicates that there may be a leak. By analyzing the noise, if the target noise exists, it indicates that there is a leak, and thus a leak notification is performed. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure numerals: 1, soundproof box; 11, air inlet; 12, air outlet. DETAILED DESCRIPTION

[0023] The present application is further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 , a silent pump control method disclosed in the present application, includes a compression pump and a silent box 1, the compression pump is arranged in the silent box 1, the silent box 1 is also provided with an air inlet 11 and an air outlet 12, a fan is provided in the silent box 1, and a baffle is also provided on the silent box 1. The air outlet 12 and the air inlet 11 are both provided with the above-mentioned baffles, and the silent box 1 is also provided with a driving member for driving the baffle to block the air outlet 12 or the air inlet 11. The driving member can be a cylinder, an electric push rod or a linear module, and the baffle is provided with the above-mentioned silencer.

[0025] The silent box 1 is also equipped with a temperature detection module, a noise detection module, a storage module, and a control module. When the speed of the compression pump motor increases, the control module obtains the data detected by the noise detection module and makes a judgment. If it does not meet the standard value, an abnormality notification is issued. The control module obtains the data detected by the temperature detection module after a preset time. If it is greater than the preset value, the control module controls the fan speed to increase. The control module obtains the data detected by the temperature detection module after a preset time. The control module controls the driving member to drive the shielding plate to adjust the shielding area of ​​the air outlet 12 or the air inlet 11 according to the temperature. Two temperature modules can be set, one for detecting the temperature inside the silent box 1 and the other for detecting the ambient temperature.

[0026] The control module obtains the data detected by the noise detection module and makes a judgment. If it is less than the standard value A, the control module obtains the data detected by the temperature detection module. If it is greater than the ambient temperature, the control module controls the driving member to move the shielding plate according to the temperature, and cancels the shielding of the air outlet 12 and the air inlet 11. When the detected temperature is equal to the ambient temperature, the control module controls the driving member to move the shielding plate to block the air outlet 12 and the air inlet 11 by a preset area. After a preset time, the temperature is compared and the preset area is blocked again. When the detected temperature is greater than the ambient temperature, the preset area is blocked N times. When the detected temperature is greater than the ambient temperature, the control module controls the driving member to move the shielding plate to restore the blocking area to the N-1 times.

[0027] The control module obtains the motor speed, the noise value corresponding to the current speed stored in the storage module, and the detection data of the noise detection module. If the noise is greater than the noise value corresponding to the current speed, the temperature detected by the temperature detection module is obtained. If the temperatures are all within the normal range, a fault notification is issued.

[0028] The control module obtains temperature data and compares it with the previous temperature data. If the temperature changes significantly and has an upward trend, the control module obtains the ambient temperature. If the ambient temperature is higher than the preset value, a high ambient temperature prompt is issued. If the ambient temperature is not higher than the preset value, a pump abnormality notification is issued.

[0029] When the temperature changes significantly and has a downward trend, the control module obtains the ambient temperature. If the ambient temperature is lower than the preset value, no notification is made. If the ambient temperature is not higher than the preset value, the control module analyzes the received noise. If the target noise (gas leakage noise) exists, a leakage notification is made. If the target noise (gas leakage noise) does not exist, a suspected leakage notification is made.

[0030] The implementation principle of this embodiment is: by setting the silencer box, a good noise reduction effect can be achieved, and by setting the fan, a good heat dissipation effect can also be achieved.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
