Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm compressors, and specifically to an oil distribution disc structure of a diaphragm compressor. Background Technique

[0002] The oil distribution disc plays a crucial role in the compressor. Its main function is to achieve the compression process by separating the high-pressure chamber and the low-pressure chamber. In a diaphragm compressor, the oil distribution disc has a large number of small holes distributed, enabling the pressure oil to act uniformly on the diaphragm, pushing the diaphragm to deform, thereby changing the volume of the air chamber and achieving the compression of the gas. This structure not only simplifies the design of the compressor but also significantly improves the volumetric efficiency, reduces energy consumption, and realizes a major technological improvement. In addition, the design of the oil distribution disc also involves the flow and distribution of hydraulic oil, ensuring that the diaphragm can be uniformly stressed, and thus guaranteeing the efficiency and stability of the compression process.

[0003] According to the "oil distribution disc structure of a diaphragm compressor" provided by the Chinese patent authorization announcement number CN216044330U, the above-mentioned literature can achieve the orderly deformation of the metal diaphragm by determining the flow direction distribution of the oil. However, since the oil passage of the cylinder block is smaller than the overall size of the oil distribution disc, when the oil flows to the oil distribution holes, it needs to flow to the oil distribution holes in a right-angled manner twice in the piston cavity of the cylinder block. This flow path undoubtedly increases the flow resistance of the oil, and thus it is necessary to increase the driving power of the piston to a certain extent to counteract the flow resistance of the oil. For this reason, we provide an oil distribution disc structure of a diaphragm compressor to solve the above problems. Content of the Utility Model

[0004] To solve the above problems, that is, to solve the problems proposed in the above background technique, the utility model proposes an oil distribution disc structure of a diaphragm compressor, including an oil distribution disc. A conical block is integrally formed at the central position of the bottom of the oil distribution disc, and a plurality of interconnected oil passages are opened at the bottom of the oil distribution disc. The plurality of oil passages are arranged in a circular array centered on the conical block. A first oil hole is opened inside the oil distribution disc corresponding to the conical block, and a second oil hole is opened in the oil passage. The second oil hole is arranged in an outwardly expanding inclined shape.

[0005] Preferably, a chamfer design is made between the conical block and the oil passage to further reduce the flow resistance of the oil.

[0006] Preferably, the inclination angle of the second oil hole can be set to 10° - 20°.

[0007] Preferably, a plurality of mounting holes are opened at the inner edge position of the oil distribution disc.

[0008] The beneficial technical effects of the present utility model are as follows: With the design of the conical block and the inclined second oil holes, the flow resistance of the oil entering the second oil holes can be reduced, thereby realizing the pressurization and decompression of the metal diaphragm, promoting the deformation of the metal diaphragm, and thus changing the volume of the air chamber on the other side of the metal diaphragm to achieve the compression of the gas, making the compression of the oil by the piston more efficient.

[0012] The preferred embodiments of the present utility model will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0013] The present utility model provides an oil distribution disk structure for a diaphragm compressor, including an oil distribution disk 1. A conical block 2 is integrally formed at the center position of the bottom of the oil distribution disk 1. A plurality of interconnected oil passages 3 are provided at the bottom of the oil distribution disk 1. The plurality of oil passages 3 are arranged in a circular array centered on the conical block 2. A first oil hole 4 is provided inside the oil distribution disk 1 corresponding to the conical block 2. A second oil hole 5 is provided in the oil passage 3. The second oil hole 5 is arranged in an outwardly expanding inclined shape. The design of the conical block 2 enables the oil to enter the oil passage 3 with a relatively gentle flow path and, through the outwardly expanding inclined shape of the second oil hole 5, enables the oil to enter the second oil hole 5 gently, reducing the resistance of the oil being pressed towards the metal diaphragm, thereby improving the overall power transmission.

[0014] Specifically, a chamfer design is made between the conical block 2 and the oil passage 3 to further reduce the flow resistance of the oil. The inclination angle of the second oil hole 5 can be set to 10° - 20°. In actual use, twelve second oil holes 5 are provided in each oil passage 3, with every three as a group. The inclination angle of the group of second oil holes 5 close to the conical block 2 is 5°, the inclination angle of the second group of second oil holes 5 is 10°, the inclination angle of the third group of second oil holes 5 is 15°, and the inclination angle of the fourth group of second oil holes 5 is 20°. This design can achieve the effect that the farther the oil is from the conical block 2, the smaller the resistance.

[0015] Working principle: When using the compressor, the oil enters the piston chamber 8 from the oil inlet of the cylinder block 7, and drives the piston in the piston chamber 8 to reciprocate through the crank connecting mechanism, so that the oil is compressed towards the cone block 2 at the piston chamber 8. At this time, since the cone block 2 corresponds to the piston chamber 8, part of the oil will be directly discharged to the metal diaphragm through the first oil hole 4, and the remaining oil will flow into the oil passage 3 at an oblique flow path through the cone block 2, and enter the inclined second oil hole 5 under the compression of the piston. The oil in the second oil hole 5 will continue to be pressed towards the metal diaphragm, thereby realizing the pressurization and decompression of the metal diaphragm, promoting the deformation of the metal diaphragm, and thus changing the volume of the air chamber on the other side of the metal diaphragm to realize the compression of the gas. And this design of the oil distribution disc 1 changes the flow path of the oil, reduces the flow resistance of the oil, and makes the compression of the oil by the piston more efficient.
