Description

Technical Field

[0001] The present invention relates to a pressure stabilizing structure, in particular to a pressure stabilizing structure of a diaphragm booster pump, and belongs to the technical field of booster pumps. Background Art

[0002] In the 180-degree range where the eccentric wheel starts to rise, the water absorption is converted to water supply in the initial stage, and the pressure does not reach 0.7MPa. During this period, only chamber 1 is supplying water, so the water supply is also converted between chamber 1 and chamber 2, which inevitably causes fluctuations in the high-pressure chamber pressure. This fluctuation is directly reflected in the connection between the outlet pipe and the booster pump outlet. The outlet pipe will vibrate significantly, causing vibration and noise of the entire machine. A diaphragm booster pump pressure stabilizing structure is now proposed to reduce this pressure fluctuation. By adding a rubber or TPV material pressure stabilizing membrane, when the pressure stabilizing membrane works at a pressure of about 0.7MPa, the pressure fluctuation is alleviated and improved through the elastic deformation of the pressure stabilizing membrane. When the pressure increases, the volume of the high-pressure chamber increases, thereby suppressing the pressure change. When the pressure decreases, the diaphragm shrinks and the volume decreases, resulting in smaller pressure fluctuations. Summary of the Invention

[0006] Furthermore, the high-pressure chamber of the upper shell is connected to the upper shell through a pressure-stabilizing hole. A groove is provided on the periphery of the pressure-stabilizing hole, and a sealing rib of the upper shell is provided on the inner flange of the groove.

[0007] Furthermore, the shape of the voltage stabilizing membrane is consistent with the shape of the pressure stabilizing cavity of the upper shell, and a voltage stabilizing membrane flange is provided on the voltage stabilizing membrane, and the voltage stabilizing membrane flange matches the pressure stabilizing cavity groove of the upper shell.

[0008] Furthermore, the voltage stabilizing membrane is made of rubber or TPV material.

[0010] Furthermore, a pressure relief valve cover is provided on the pressure relief valve component, a pressure stabilizing membrane cover is provided on the upper shell, and the pressure relief valve cover and the pressure stabilizing membrane cover are combined to form a control combination cover, and the control combination cover is provided with screws, the number of screws is six, and the control combination cover formed by the combination of the pressure relief valve cover and the pressure stabilizing membrane cover is fastened to the upper shell by six screws.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The pressure-stabilizing structure described in the present invention can reduce vibration at the connection between the water outlet pipe and the booster pump outlet. By adding a rubber or TPV material pressure-stabilizing membrane, when the pressure-stabilizing membrane operates at a pressure of approximately 0.7 MPa, pressure fluctuations are alleviated and improved through the elastic deformation of the pressure-stabilizing membrane. When the pressure increases, the volume of the high-pressure chamber increases, thereby suppressing pressure changes. When the pressure decreases, the diaphragm shrinks and the volume decreases, resulting in smaller pressure fluctuations. This improves the fluctuation range of the peak water supply pressure of the diaphragm booster pump and provides more stable water pressure for the RO membrane of the water purifier. At the same time, the reduction in pressure fluctuations will significantly improve the vibration of the water outlet pipe at the water outlet connection pipe position, reducing the vibration and noise of the entire machine.

[0031] The principle and process of using the diaphragm booster pump: no matter the popular 3-chamber pump, 4-chamber pump and 5-chamber pump on the market, theoretically, at any moment, it is in the water absorption state within 180 degrees and in the compression state within the other 180 degrees, the 3-chamber pump is always 1-chamber water supply or 2-chamber water supply, the 5-chamber pump is also between 2-chamber water supply and 3-chamber water supply, even the most balanced 4-chamber pump, it cannot be 2-chamber water supply at the same time, because the vibration body fixing frame makes nutational motion under the operation of the eccentric wheel, because the pressure of the water outlet chamber is 0.7MPa, within the 180-degree range that the eccentric wheel starts to rise, at the initial stage, it is converted from water absorption to water supply, the pressure cannot reach 0.7MPa, during this period, only 1-chamber is water supply, therefore, it is also converted between 1-chamber water supply and 2-chamber water supply, which cannot avoid causing the fluctuation of the pressure of the high-pressure chamber. The fluctuation is directly reflected in the water outlet pipe and the outlet connection of the booster pump, the water outlet pipe will have a large amplitude of vibration, causing the vibration and noise of the whole machine, the pressure stabilizing structure of the diaphragm booster pump is to reduce the pressure fluctuation, by increasing the rubber or TPV material pressure stabilizing film, when the pressure stabilizing film works at about 0.7MPa, the pressure fluctuation is relieved and improved through the elastic deformation of the pressure stabilizing film, when the pressure increases, the volume of the high-pressure chamber becomes larger, thereby inhibiting the pressure change, when the pressure becomes smaller, the film sheet shrinks and the volume becomes smaller, thereby causing the pressure fluctuation to become smaller.
