Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a desorbed gas compressor. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle.

[0003] Existing compressor crankcases are butt-joint structure crankcases, meaning the compressor crankcase is composed of three crankcases bolted together. Each crankcase and the central body are an integral structure, and the coaxiality of the six main shaft holes is ensured by CNC machining. This results in insufficient rigidity and poor resistance to deformation under heavy loads. The butt-joint crankcases are prone to displacement during operation, and cracks may appear at the stress points of the crankcases. The central body and crankcases are integral castings without anchor bolts, causing large vibrations when the crankcase is started, thus causing a series of problems. To address these issues, we propose the gas desorption compressor. Utility Model Content

[0004] The main purpose of this utility model is to provide a desorbed gas compressor. By replacing the existing compressor body, which is assembled by fastening three crankcases together with bolts, with an integrated body body containing an internal crankcase structure, and by changing the internal structure of the crankcase and adding reinforcing ribs to the body, the strength of the crankcase is improved. In addition, the existing one-piece molded middle body of the crankcase is disassembled into independent middle bodies for assembly in this utility model. Three tie rods are added above and below the slide of the middle body. Anchor bolts are added to the six independent parts of the middle body, for a total of twenty-four anchor bolts. This makes the contact between the crankcase and the ground foundation closer and more solid, and the equipment operates more stably, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The gas compressor includes a front cover, a main body, support beam A, a bearing cover, a bearing, a top cover, support beam B, and a middle body. Three crankcases are housed within the main body. A front cover and an oil cover are mounted at each end of the main body, and an oil pipe is installed along the length of the main body between the front cover and the oil cover. Support beam A is located within the main body behind the front cover and the oil cover, and support beam B is located within the main body between support beams A. A middle body is mounted on the top of the main body. The top cover and the body cover are equipped with a breathing device mechanism. Six sets of body parts are symmetrically installed on both sides of the body near the crankcase. Three ribs with tie rods are symmetrically arranged in the slide of the body. A tie rod is installed in the body below the breathing device mechanism. Anchor bolts are installed below the body. A bearing is installed in the crankcase near the inside of the body through a bearing cover. A crankcase crossbeam is provided at the bottom of the crankcase near the inside of the body.

[0007] Furthermore, four sets of anchor bolts are installed below the central body;

[0008] By adopting the above technical solution, a total of anchor bolts were added to the six independent parts of the central body, making the central body and crankcase more closely and firmly in contact with the ground, thus ensuring more stable equipment operation.

[0009] Furthermore, the fuselage body is provided with box-shaped reinforcing ribs inside;

[0010] By adopting the above technical solution, the crankcase inside the fuselage body is strengthened by adding reinforcing ribs to improve the strength of the crankcase and enhance the load-bearing capacity of the crankcase and the middle body.

[0011] Furthermore, the multiple independent covers of the fuselage top cover are bolted to the top opening of the fuselage body, and the cover of the fuselage top cover is provided with a cover hole for passing through the tube seat below the respirator mechanism, and the tube seat of the respirator mechanism communicates downward with the fuselage body.

[0012] By adopting the above technical solution, the fuselage top cover is locked to the top of the fuselage body with bolts to seal it, while the breathing apparatus mechanism passes through the cover of the fuselage top cover and communicates with the fuselage body.

[0013] Furthermore, the outer seat plate of the respirator mechanism is locked to the top cover of the body with bolts;

[0014] By adopting the above technical solution, the outer seat plate of the respirator mechanism can be bolted to the outside of the top cover of the body for support.

[0015] Furthermore, the main body of the engine has bearings symmetrically installed in the three sets of crankcase grooves through six sets of bearing covers.

[0016] By adopting the above technical solution, the machine body can install multiple sets of bearings for the installation of the compressor main shaft by fitting six sets of bearing covers in the shaft grooves of its three sets of crankcases.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model replaces the existing compressor body, which is assembled by fastening three crankcases together with bolts, with an integrated body body that has an internal crankcase structure. Furthermore, the change in the internal structure of the crankcase, combined with the addition of reinforcing ribs to the housing, improves the strength of the crankcase.

[0019] Furthermore, the existing one-piece crankcase body is disassembled into independent bodies for assembly in this utility model. Three tie rods are provided above and below the slide of the body. Anchor bolts are added to the six independent parts of the body (four anchor bolts for each body), for a total of twenty-four anchor bolts. This makes the crankcase more closely and firmly connected to the ground foundation, and the equipment operates more stably. Attached Figure Description

[0028] Four sets of anchor bolts 12 are installed below the middle body 11;

[0029] By adopting the above technical solution, a total of 24 anchor bolts 15 were added to the six independent parts of the middle body 11, making the middle body 11 and the crankcase more closely and firmly in contact with the ground, thus ensuring more stable equipment operation.

[0030] The fuselage body 2 is provided with box-shaped reinforcing ribs inside;

[0031] By adopting the above technical solution, the crankcase inside the fuselage body 2 is strengthened by adding reinforcing ribs to improve the strength of the crankcase and enhance the load-bearing capacity of the crankcase and the middle body 11.

[0032] The multiple independent covers of the top cover 6 are bolted to the top opening of the body 2, and the top cover 6 has a cover hole for passing through the tube seat below the respirator mechanism 8. The tube seat of the respirator mechanism 8 is connected downward to the body 2.
