Description

Technical Field

[0001] This utility model relates to the field of rotary compressor technology, specifically a low-pressure vane rotary compressor with an oil reservoir. Background Technology

[0002] Rotary compressors are one of the many types of compressors currently available. When a rotary compressor is working, there is a lot of friction between the vane surface and the cylinder. After running for a long time, this may cause wear on the components, which in turn affects the reliability of the compressor. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the above-mentioned rotary compressors and to provide a low-pressure vane rotary compressor with an oil storage tank.

[0004] The specific solution of this utility model is: a sliding vane with a low-pressure surface and an oil storage groove, including a sliding vane body. When the sliding vane body is working, one side is a high-pressure surface and the other side is a low-pressure surface. An oil storage groove is provided on the low-pressure surface. The oil storage groove is used to store lubricating oil to reduce the friction between the sliding vane and the compressor cylinder.

[0005] Furthermore, there are multiple oil storage tanks, and the opening size of each oil storage tank is different.

[0006] Furthermore, the oil storage tank is rectangular, circular, or elliptical in shape.

[0007] Furthermore, the depth of the oil storage tank is 0.5mm-1mm.

[0008] This utility model also provides a rotary compressor, including a cylinder base, a cylinder provided in the cylinder base, and the aforementioned sliding vane installed inside the cylinder.

[0009] Compared with the prior art, this utility model has the following advantages: by setting an oil storage tank on the low-pressure side of the sliding vane, the oil storage tank contains a certain amount of lubricating oil, which greatly reduces the friction between the sliding vane and the cylinder when the compressor is running, thereby improving the reliability of the rotary compressor operation.

[0015] Example 1

[0016] See Figure 1-3 This embodiment is a sliding vane with a low-pressure surface 3 and an oil storage tank 2, including a sliding vane body 1. When the sliding vane body 1 is working, one side is a high-pressure surface 4 and the other side is a low-pressure surface 3. An oil storage tank 2 is provided on the low-pressure surface 3. The oil storage tank 2 is used to store lubricating oil to reduce the friction between the sliding vane and the compressor cylinder.

[0017] Furthermore, the oil storage tank 2 is rectangular, circular, or elliptical in shape.

[0018] Furthermore, the depth H of the oil storage tank 2 is 0.5mm-1mm.

[0019] Furthermore, the opening of the oil storage tank 2 is chamfered.

[0020] This embodiment also provides a rotary compressor, including a cylinder base, a cylinder provided in the cylinder base, and the aforementioned sliding vane installed inside the cylinder.

[0021] See Example 2 Figure 4 This embodiment is similar in structure to Embodiment 1, except that there are multiple oil storage tanks 2, and the opening size of each oil storage tank 2 is different.

[0022] When the rotary compressor of this invention is working, a lubricating oil layer is formed between the low-pressure surface 3 of the sliding vane and the cylinder, which greatly reduces the friction between the sliding vane and the cylinder, thereby improving the reliability of the compressor operation.
