Embodiment Construction

[0044] refer to Figure 1 to Figure 6 The compressor in the embodiment of the present invention will be described in detail. This embodiment is to use figure 1 An example of a screw compressor for cooling circulation is installed horizontally on the base 2 around the body of the compressor 1 shown. The container 3 of the compressor 1 houses a compression mechanism 4 and an electric motor 5 for driving the compression mechanism, and a reservoir 6 for storing liquid supplied to lubricate sliding parts including the compression mechanism 4 is arranged. The working compressed fluid is cooling gas. Liquids such as lubricating oil 7 are used as liquids for lubricating or sealing the sliding parts of the compression mechanism 4, which are compatible with the coolant. However, the present invention is not limited thereto. Basically, it is possible to use a container that has a compression mechanism and a liquid reservoir capable of storing liquid such as lubricating a sliding port...

Abstract

Lubricating liquid fed from a reservoir to a compression mechanism is collected by a circumferential wall that surrounds the drive shaft of the compression mechanism and rotates synchronously with it immediately after liquid is discharged into the space inside the housing with or without compressed fluid. Liquid is then urged outward under centrifugal force from an outlet formed at a preset axial location of the circumferential wall. Exiting liquid is received by a fixed liquid return cover that surrounds the circumferential wall near its outlet and led back to the reservoir.

Description

field of invention [0001] The invention relates to a method and device for supplying and recovering liquid from a compressor compression mechanism with a container built in a compression mechanism and a liquid storage part, wherein the liquid storage part stores liquid capable of lubricating the sliding part including the compression mechanism. technical background [0002] This compressor can be made hermetically sealed by connecting the container to the cooling circulator. Once the compression mechanism is driven, the following operations can be repeated: taking the coolant in the cooling circulator through the suction port of the container, compressing the coolant and discharging it into the container, and then supplying it to the cooling circulator from the discharge port of the container. At the same time, the lubricating oil stored in the oil storage part in the container is supplied to the sliding part including the compression mechanism directly or / and with the movem...
