Description

Compressor Oil Vapor Recovery Structure

technical field

The utility model relates to a compressor oil gas recovery structure, in particular to a compressor oil gas recovery structure for intercepting lubricating oil gas formed in a scroll compressor.

Background technique

In the known scroll compressor, since it has many moving parts and friction occurs between the moving parts, lubricating oil is often used to provide lubrication between the friction surfaces to reduce the friction and further improve the compression machine energy efficiency. On the other hand, since the lubricating oil gas of this type of scroll compressor is divided into various components, it is easy to entrain the lubricating oil gas into the high-pressure working gas generated by it, causing the gradual loss of lubricating oil and affecting the lubrication work. Therefore, the utility model is improved based on the defects of the known scroll compressors.

Contents of this utility model

The main purpose of the utility model is to provide a compressor oil gas recovery structure, which is used for recovering lubricating oil gas entrained in the working gas. It mainly installs a scroll device that generates and outputs high-pressure working gas and a lubrication device that provides lubricating oil and gas for each component in the closed structure shell of the scroll compressor. It is characterized in that:

The lubricating device provides lubricating oil required by the scroll compressor, including: an oil storage tank and an oil retaining plate; the oil storage tank is arranged below the scroll device for storing the lubricating oil; the oil retaining The plate is formed by a plate body surrounding the scroll device, and an outer channel leading to the oil storage tank is at least partially formed between the oil blocking plate and the housing;

After the high-pressure working gas generated by the scroll device is output, the working gas is guided and transported back to the scroll compressor through a return pipe; and

The oil trap extends at least to the return point of the return pipe, so that the working gas flowing back from the return pipe will directly impact the oil trap, and the oil gas in the working gas will adhere to the oil trap , and is subjected to the action of gravity to gradually flow along the oil blocking plate and flow back into the oil storage tank from the outer channel. The working gas flowing back from the return pipe will directly impact the oil trap, and the oil and gas in the working gas will adhere to the oil trap and gradually follow the oil trap under the action of gravity, Flow back into the oil storage tank from the outer channel.

Detailed ways

In order to make those skilled in the art understand the purpose, features and effects of the present utility model, the following specific embodiments are illustrated in detail with accompanying drawings.

Fig. 1 is a schematic cross-sectional view of a preferred embodiment of the compressor oil-gas recovery structure of the present invention, which is mainly to arrange a scroll device 3 and a lubricating device 5 in the casing 1 of the closed structure of the scroll compressor 10, wherein:

The scroll device 3 includes a fixed scroll 31 and an orbiting scroll 33 arranged on a support base 35 . The compressed low-pressure working gas 37 entering the compressor 10 through the return pipe 13 is used to generate and output the high-pressure working gas 38, and the high-pressure working gas 38 produced by the scroll device 3 can be transported to the high-pressure working gas 38 through the outlet pipe 11. The low-pressure working gas 37 is guided and sent back to the scroll compressor 10 through the return pipe 13 from the above-mentioned external specific device.

The lubricating device 5 is used to provide lubricating oil required by the scroll compressor 10 , and has an oil storage tank 51 and an oil retaining plate 53 . The oil storage tank 51 is arranged below the scroll device 3 for storing lubricating oil, and the plate body of the oil blocking plate 53 is formed around the scroll device 3, and at least partly formed between the oil blocking plate 53 and the housing 1 is a hole leading to the storage tank. The outer channel 55 of the oil groove 51. An inner channel 57 penetrating to the oil storage tank 51 is also at least partially formed between the oil blocking plate 53 and the scroll device 3 .

The return pipe 13 runs through the casing 1 to guide and transport the low-pressure working gas 37 back to the scroll compressor 10, and the oil blocking plate 53 extends at least to the place where the return pipe 13 runs through the casing 1, so that the low-pressure working gas flowing back from the return pipe 13 37 can directly impact oil blocking plate 53.

The casing 1 is made of castings, and makes the scroll compressor 10 form a semi-tight scroll compressor structure.

Based on the above-mentioned compressor oil gas recovery structure of the utility model, when the lubricating oil gas of each component of the scroll compressor 10 enters the outlet pipe 11 along with the high-pressure working gas 38 output by the scroll compressor 10, the low-pressure working gas 37 flows from the return pipe 13 When returning to the scroll compressor 10, the low-pressure working gas 37 will directly enter the outer channel 55 and hit the oil blocking plate 53, as shown in Figure 2, so that the oil and gas in the low-pressure working gas 37 will adhere to the oil blocking plate 53, and is subjected to the effect of gravity and gradually flows back in the oil storage tank 51 from the outer channel 55 along the oil trap 53.

The lubricating oil and gas provided by the lubricating device 5 are distributed between the fixed scroll 31, the orbiting scroll 33, and the support seat 35 in the scroll device 3, which may movement, and the lubricating oil gas is sprayed laterally to the casing 1 of the scroll compressor 10 . Therefore, the oil blocking plate 53 in the lubricating device 5 of the present utility model can be extended to the position where the scroll device 3 generates the side splashing of the lubricating oil gas, so that the splashed lubricating oil gas will adhere to the oil blocking plate 53 and Under the action of gravity, it gradually flows back into the oil storage tank 51 from the inner channel 57 along the oil blocking plate 53 .

Fig. 3 is a schematic cross-sectional view of another specific embodiment of the oil gas recovery structure of the compressor of the present invention. The top of the oil trap 53 in the lubricating device 5 extends radially inwards to form an annular top 53a, and fully covers the scroll device 3, so that the lubricating oil gas in the scroll device 3 will not spray from the top of the oil trap 53. Splash to the outer passage 55, and increase the area where the oil baffle plate 53 can intercept lubricating oil and gas.

The compressor oil gas recovery structure of the utility model can achieve the following effects:

The oil gas recovery structure of the compressor of the utility model can condense and recover the lubricating oil gas carried by the working gas into its oil storage tank through the set oil blocking plate, so as to avoid the gradual loss of lubricating oil.

2. In the compressor oil gas recovery structure of the utility model, the oil blocking plate surrounds the scroll device, so that the lubricating oil gas splashed in the scroll device will not directly contact the returning working gas, and will condense until the oil is blocked. On the board, it is recovered to its oil storage tank, thus further reducing the chance of lubricating oil gas being entrained out of the compressor by the working gas.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the patent scope of the present utility model. All equivalent structural transformations made by using the description of the utility model and the contents of the accompanying drawings, or directly or indirectly used in other related Technical fields are all included in the patent scope of the present utility model in the same way.
