Description

At present, the pump body sliding vane friction pair relies on the cooperation gap (10-26um) between the cylinder sliding vane groove and the sliding vane for oil supply lubrication. Since the cooperation gap is very small, the amount of refrigerant oil that can enter the gap for lubrication is insufficient to meet the lubrication demand of the sliding vane friction pair.

[0031] Referring to Figures 1 to 7 The first aspect of the present application provides a pump body structure 10, comprising a lower flange 300, a cylinder 200 and an upper flange 100 connected in sequence from bottom to top; the cylinder 200 is provided with a sliding vane side lubrication structure 210, the upper flange 100 is provided with a first oil groove 110 and an oil guide hole structure 120 for receiving the refrigerant oil pumped by the crankshaft assembly 400, the first oil groove 110 is located above the sliding vane side lubrication structure 210, the upper surface of the lower flange 300 is provided with a second oil groove 310, the second oil groove 310 is located below the sliding vane side lubrication structure 210, and the oil guide hole structure 120 is used to guide the refrigerant oil to the sliding vane side lubrication structure 210, the first oil groove 110 and the second oil groove 310 to lubricate the two sides of the sliding vane 500 in the sliding vane side lubrication structure 210, the upper end face of the sliding vane 500 and the lower end face of the sliding vane 500 respectively.

[0032] In the embodiment, the pump body structure 10 comprises a lower flange 300, a cylinder 200 and an upper flange 100, wherein the lower flange 300, the cylinder 200 and the upper flange 100 are sequentially connected from bottom to top, and are preferably fixedly connected by screws in the embodiment. In addition, the cylinder 200 is provided with a sliding vane side lubrication structure 210, and the sliding vane side lubrication structure 210 is provided with a movable sliding vane 500. The upper flange 100 is provided with a guide hole structure 120 for receiving the refrigerated oil pumped by the crankshaft assembly 400. The guide hole structure 120 is located above the sliding vane side lubrication structure 210 and communicates with the sliding vane side lubrication structure 210, so that the refrigerated oil in the guide hole structure 120 can be guided into the sliding vane side lubrication structure 210 to lubricate the two side surfaces of the sliding vane 500. The lower surface of the upper flange 100 is provided with a first oil groove 110, and the first oil groove 110 is located above the sliding vane 500 in the sliding vane side lubrication structure 210. The first oil groove 110 and the upper end surface of the sliding vane 500 form a first gap, so that the refrigerated oil can lubricate the upper end surface of the sliding vane 500 through the first gap. In addition, the upper surface of the lower flange 300 is provided with a second oil groove 310, and the second oil groove 310 is located below the sliding vane 500 in the sliding vane side lubrication structure 210. The second oil groove 310 and the sliding vane 500 form a second gap, so that the refrigerated oil can lubricate the lower end surface of the sliding vane 500 through the second gap. The guide hole structure 120, the sliding vane side lubrication structure 210, the first oil groove 110 and the second oil groove 310 are in communication, so that the refrigerated oil can lubricate the two side surfaces of the sliding vane 500 in the sliding vane side lubrication structure 210, the upper end surface of the sliding vane 500 and the lower end surface of the sliding vane 500, respectively.

[0033] In specific implementation, when the pump body structure 10 is normally working, the crankshaft assembly 400 pumps the refrigerated oil into the guide hole structure 120 of the upper flange 100. The refrigerated oil passes through the sliding vane side lubrication structure 210 in communication with the guide hole structure 120 to lubricate the two side friction pairs of the sliding vane 500 in the sliding vane side lubrication structure 210. In addition, the refrigerated oil has oil pressure, and when lubricating the two side friction pairs of the sliding vane 500, the refrigerated oil enters the second oil groove 310 of the lower flange 300 to lubricate the lower end friction pair of the sliding vane 500. Part of the refrigerated oil passes through the first oil groove 110 of the upper flange 100 to lubricate the upper end friction pair of the sliding vane 500.

[0034] In summary, the pump body structure 10 in the above embodiments achieves lubrication of the four-sided friction pairs of the slide plate 500, including the two sides, the upper end face, and the lower end face, through the oil passage formed by the oil guide hole structure 120 on the upper flange 100, the first oil groove 110, the slide plate side lubrication structure 210 on the cylinder 200, and the second oil groove 310 on the lower flange 300, thereby reducing the friction loss at the slide plate 500.

[0035] In one embodiment, such as Figures 1-7 As shown, the sliding vane side lubrication structure 210 includes a third oil passage groove 211 and a sliding vane groove assembly 212. The third oil passage groove 211 is disposed on the upper surface of the cylinder 200 and is located below the oil guide hole structure 120. The sliding vane groove assembly 212 is located on one side of the third oil passage groove 211. The third oil passage groove 211 communicates with one side of the oil guide hole structure 120, and the other side of the third oil passage groove 211 communicates with the oil guide hole structure 120.

[0036] In this embodiment, the sliding vane-side lubrication structure 210 consists of a third oil passage groove 211 and a sliding vane groove assembly 212. The third oil passage groove 211 is disposed on the upper surface of the cylinder 200 and is located below the oil guide hole structure 120. Preferably, the third oil passage groove 211 is an arc-shaped groove to facilitate the flow of refrigeration oil into the sliding vane groove assembly 212. Furthermore, the sliding vane groove assembly 212 is located on one side of the third oil passage groove 211, and the third oil passage groove 211 communicates with one side of the oil guide hole structure 120, while the other side of the third oil passage groove 211 communicates with the oil guide hole structure 120. In this embodiment, the sliding vane groove assembly 212 is preferably a rectangular groove structure, but it can also be designed with other groove structures according to the cylinder 200, which is not specifically limited here. A movable sliding vane 500 is provided inside the sliding vane groove assembly 212. In summary, this embodiment uses the oil guide hole structure 120, the third oil channel 211, and the sliding plate groove assembly 212 to allow the refrigeration oil in the oil guide hole structure 120 to pass through the third oil channel 211 and the sliding plate groove assembly 212 in sequence, thereby achieving lubrication of both sides of the sliding plate 500.

[0037] In one embodiment, such as Figures 1-7As shown, the slide groove assembly 212 includes a first oil passage chute group 2121, a slide groove 2122, and a second oil passage chute group 2123, the slide groove 2122 is located between the first oil passage chute group 2121 and the second oil passage chute group 2123, the first oil passage chute group 2121 is located on the left side of the slide groove 2122, the second oil passage chute group 2123 is located on the right side of the slide groove 2122, and the first oil passage chute group 2121, the slide groove 2122 and the second oil passage chute group 2123 are in communication.

[0038] In this embodiment, in order to realize the lubrication of the friction pairs on both sides of the slide 500, the slide groove assembly 212 is composed of a first oil passage chute group 2121, a slide groove 2122 and a second oil passage chute group 2123; wherein the slide groove 2122 is located at the center position between the first oil passage chute group 2121 and the second oil passage chute group 2123, and the slide groove 2122 is provided with a movable slide 500; in addition, the first oil passage chute group 2121 is located on the left side of the slide groove 2122, the second oil passage chute group 2123 is located on the right side of the slide groove 2122, and the first oil passage chute group 2121, the slide groove 2122 and the second oil passage chute group 2123 are in communication. In specific implementation, when the pump body structure 10 is normally working, the crankshaft assembly 400 pumps the refrigerant oil into the oil guide hole structure 120 of the upper flange 100, and the refrigerant oil is guided to the first oil passage chute group 2121 of the slide groove assembly 212 through the third oil passage groove 211 in communication with the oil guide hole structure 120; and under the action of the refrigerant oil pressure, another part of the refrigerant oil is guided to the second oil passage chute group 2123 of the slide groove assembly 212 through the first oil passage groove 110, so that the refrigerant oil flows through the left and right sides of the slide 500 in the slide groove 2122 through the first oil passage chute group 2121 and the second oil passage chute group 2123 of the slide groove assembly 212, thereby lubricating the friction pairs on both sides of the slide 500.

[0039] In an embodiment, as shown in Figures 1-7 The first oil passage chute group 2121 includes a first oil passage chute 21211 and a second oil passage chute 21212, the first oil passage chute 21211 and the second oil passage chute 21212 are arranged in parallel; the second oil passage chute group 2123 includes a third oil passage chute 21231 and a fourth oil passage chute 21232, the third oil passage chute 21231 and the fourth oil passage chute 21232 are arranged in parallel; the first oil passage chute 21211 and the third oil passage chute 21231 are symmetrically arranged, and the second oil passage chute 21212 and the fourth oil passage chute 21232 are symmetrically arranged.

[0040] In the embodiment, the first oil passage chute group 2121 preferably comprises a first oil passage chute 21211 and a second oil passage chute 21212, and the second oil passage chute group 2121 preferably comprises a third oil passage chute 21231 and a fourth oil passage chute 21232; wherein the first oil passage chute 21211 and the second oil passage chute 21212 are arranged in parallel, and both the first oil passage chute 21211 and the second oil passage chute 21212 are located on the left side of the slide groove 2122; the third oil passage chute 21231 and the fourth oil passage chute 21232 are arranged in parallel, and both the third oil passage chute 21231 and the fourth oil passage chute 21232 are located on the right side of the slide groove 2122; in addition, the first oil passage chute 21211 and the third oil passage chute 21231 are symmetrically arranged, and the second oil passage chute 21212 and the fourth oil passage chute 21232 are symmetrically arranged, so that in the specific implementation process, after the crankshaft assembly 400 pumps the refrigerant oil into the oil guide hole structure 120 of the upper flange 100, the refrigerant oil is guided to the first oil passage chute 21211 and the second oil passage chute 21212 through the third oil passage groove 211 communicated with the oil guide hole structure 120, and another part of the refrigerant oil is guided to the third oil passage chute 21231 and the fourth oil passage chute 21232 through the first oil passage groove 110 under the oil pressure of the refrigerant oil, so that the refrigerant oil is uniformly distributed to the left and right sides of the slide groove 2122, thereby lubricating the friction pairs on both sides of the slide 500.

[0041] In addition, in this embodiment, to ensure sufficient lubrication of the sliding vane 500 friction pair under high frequency and high operating speed, the angle of any one of the oil passages 21211, 21212, 31231, and 41232 is adjusted to an effective lubrication design for the sliding vane 500 friction pair under high frequency and high operating speed of the compressor. Specifically, since the sliding vane 500 in the cylinder 200 has two main directions of movement, one direction is towards the center of the cylinder 200 (outward stroke), which is mainly affected by the spring force of the spring hole 230 on the cylinder 200, and the other direction is away from the center of the cylinder 200 (return stroke), which is mainly affected by the force of the roller 600 on the cylinder 200 and the force of the compressed gas. The force is greater during the return stroke. Therefore, the angles of the first oil passage 21211, the second oil passage 21212, and the fourth oil passage 21232 are adjusted to ensure effective lubrication of the sliding vane 500 friction pair under high frequency and high operating speed of the compressor. 2. The angle α of any one of the oil passages 21231 and 21232 should be designed to be away from the center of the cylinder 200. However, due to the structural limitations of the cylinder 200 itself, α must satisfy 0 ≤ tanα ≤ l2 / (h1 + d1 / 2), where h1 represents the cylinder height of the cylinder 200; d1 represents the diameter of the spring hole 230 in the cylinder 200; and l2 represents the distance between the exhaust hole 220 and the spring hole 230 on the cylinder 200. Therefore, through the design of the angles of the first oil passage 21211, the second oil passage 21212, the third oil passage 21231, and the fourth oil passage 21232, the pump body structure 10 can effectively lubricate the friction pair of the sliding vane 500 under high frequency and high operating speed while reducing friction power consumption.

[0042] In one embodiment, such as Figures 1-7 As shown, the oil guide hole structure 120 includes a flexible groove side oil hole 121, an oil guide cavity assembly 122, and an opening 123. The flexible groove side oil hole 121 is disposed on the side of the upper flange 100 near the crankshaft assembly 400.

The flexible groove side oil hole 121, the oil guide cavity, and the opening 123 are connected.

[0043] In the embodiment, the oil guiding hole structure 120 comprises a flexible groove side oil hole 121, an oil guiding cavity assembly 122 and an opening hole 123. The flexible groove side oil hole 121 is arranged on one side of the upper flange 100 close to the crankshaft assembly 400, so that the refrigerated oil enters the flexible groove side oil hole 121. The oil guiding cavity assembly 122 is arranged in the inner cavity of the upper flange 100. The opening hole 123 is arranged below the oil guiding cavity assembly 122 and on the lower surface of the upper flange 100. In addition, the flexible groove side oil hole 121, the oil guiding cavity and the opening hole 123 are in communication, so that the refrigerated oil entering from the flexible groove side oil hole 121 passes through the oil guiding cavity assembly 122 and the opening hole in turn, and then flows into the third oil guiding groove 211 of the cylinder 200, so as to lubricate the sliding vane 500 subsequently. In addition, since the passage area determines the refrigerated oil flow, in the embodiment, the area of the flexible groove side oil hole 121 and the total passage area of the first oil guiding groove 21211, the second oil guiding groove 21212, the third oil guiding groove 21231 and the fourth oil guiding groove 21232 are designed to be approximately equal, so that the refrigerated oil passing through the flexible groove side oil hole 121 completely enters the first oil guiding groove 21211, the second oil guiding groove 21212, the third oil guiding groove 21231 and the fourth oil guiding groove 21232, thereby ensuring sufficient lubrication of the sliding vane 500.

[0044] In an embodiment, as shown in Figures 1-6 The oil guiding cavity assembly 122 comprises an oil guiding cavity 1221 and an oil plug 1222. The oil plug 1222 is arranged at one end of the oil guiding cavity 1221, so that the refrigerated oil entering the oil guiding cavity 1221 from the flexible groove side oil hole 121 flows to the position of the opening hole 123.

[0045] In the embodiment, in order to make the refrigerated oil passing through the oil guiding cavity assembly 122 flow into the third oil guiding groove 211, the oil guiding cavity assembly 122 comprises an oil guiding cavity 1221 and an oil plug 1222. The oil plug 1222 is arranged at one end of the oil guiding cavity 1221, so that the oil guiding cavity 1221 can be blocked by the oil plug 1222, and then the refrigerated oil entering the oil guiding cavity 1221 from the flexible groove side oil hole 121 flows to the position of the opening hole 123, and then flows downward to the third oil guiding groove 211 in the cylinder 200.

[0046] In an embodiment, as shown in Figures 1-7As shown, the second oil groove 310 comprises a first vertical oil guide groove 311, a horizontal oil guide groove 312 and a second vertical oil guide groove 313, which are in communication. The first vertical oil guide groove 311 is provided with a first oil discharge hole 3111, and the second vertical oil guide groove 313 is provided with a second oil discharge hole 3131. The first oil discharge hole 3111 and the second oil discharge hole 3131 are symmetrically arranged.

[0047] In the embodiment, the second oil groove 310 comprises a first vertical oil guide groove 311, a horizontal oil guide groove 312 and a second vertical oil guide groove 313. The first vertical oil guide groove 311 and the second vertical oil guide groove 313 are both long strip-shaped oil guide grooves. The first vertical oil guide groove 311 is provided with a first oil discharge hole 3111, and the second vertical oil guide groove 313 is provided with a second oil discharge hole 3131. The first oil discharge hole 3111 and the second oil discharge hole 3131 are both used for guiding the refrigerant oil falling from both sides of the sliding vane groove 2122 on the cylinder 200 to discharge the lower flange 300.
