Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compact compressor used for multi-stage compression. Background Art

[0002] At present, the compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. Thus, the refrigeration cycle of compression, condensation (heat release), expansion, and evaporation (heat absorption) is realized. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc.

[0003] Existing compressors often vibrate to a certain extent during use, which may cause certain damage to the compressor itself during long-term use; and the compressor is usually installed in a fixed manner, which is not convenient for subsequent maintenance and repair. Therefore, a compact compressor for multi-stage compression is proposed. Utility Model Content

[0008] A further technical solution of the utility model is: there are two arc-shaped support plates, and the diameter of the arc-shaped support plates is matched with the compressor body.

[0009] A further technical solution of the utility model is that the first vibration-damping ring, the second vibration-damping ring, the buffer ring, the arc-shaped support plate and the compressor body are coaxially distributed.

[0023] Figure 1-Figure 4 The main structural components of a compact compressor for multi-stage compression are shown, which includes a compressor body 1, a vibration reduction mechanism 2 for alleviating compressor vibration is provided on the compressor body 1, a fixing mechanism 3 is provided on the vibration reduction mechanism 2, a connecting plate 4 is provided on the vibration reduction mechanism 2, a support 5 is provided on the side of the connecting plate 4 away from the compressor body 1, a mounting plate 6 is provided on the support 5, and the vibration reduction mechanism 2 is installed and fixed by the mounting plate 6.

[0024] like Figure 1 as well as Figure 3 As shown, the vibration mechanism 2 is the core component of the compact compressor for multi-stage compression, and mainly plays the role of buffering and vibration reduction, and protects the compressor body 1. The specific description is as follows:

[0025] The vibration damping mechanism 2 includes: a first vibration damping ring 21 arranged on the compressor body 1, a second vibration damping ring 22 arranged on the compressor body 1, a spring 23 arranged inside the first vibration damping ring 21 and the second vibration damping ring 22, a buffer ring 24 arranged on the spring 23, and an arc-shaped support plate 25 arranged on the buffer ring 24.

[0026] The spring 23 offsets the vibration through elastic deformation generated by elastic force, thereby protecting the compressor body 1 . There are a plurality of springs 23 , which are evenly distributed on the inner walls of the first vibration damping ring 21 and the second vibration damping ring 22 .

[0027] Meanwhile, there are two arc-shaped support plates 25 , and the diameter of the arc-shaped support plates 25 is adapted to the compressor body 1 , so that the compressor body 1 is fixedly supported by the arc-shaped support plates 25 .

[0028] The first vibration-damping ring 21 , the second vibration-damping ring 22 , the buffer ring 24 , the arc-shaped supporting plate 25 and the compressor body 1 are coaxially distributed.

[0029] like Figure 1 As shown, in order to facilitate the disassembly and assembly of the compressor body 1, the vibration damping mechanism 2 needs to be designed to be open and close. Therefore, the bottom end of the first vibration damping ring 21 is connected to the bottom end of the second vibration damping ring 22; and the top end of the first vibration damping ring 21 and the top end of the second vibration damping ring 22 are fixed in position by the fixing mechanism 3 when in contact.

[0030] like Figure 4 As shown, the fixing mechanism 3 is mainly used to fix the relative positions of the first vibration damping ring 21 and the second vibration damping ring 22. The fixing mechanism 3 includes: a fixing seat 32 arranged on the first vibration damping ring 21, a base 31 arranged on the second vibration damping ring 22, a fixing rod 33 arranged on the base 31, and a fixing knob 34 arranged on the fixing rod 33.

[0031] Among them, the end of the fixing rod 33 away from the base 31 is cylindrical and has an external thread, and the other end of the fixing rod 33 is connected to the rotating shaft of the base 31. At the same time, in order to facilitate the installation and fixation of the fixing rod 33, the fixing seat 32 is set to be concave, and the groove on it is adapted to the fixing rod 33.

[0032] Meanwhile, the fixing knob 34 is threadedly connected to the fixing rod 33 , and the first vibration-damping ring 21 and the second vibration-damping ring 22 can be brought closer to each other by rotating the fixing knob 34 until the two are in close contact.

[0033] The working principle of the utility model is as follows:

[0034] When in use, since the second vibration damping ring 22 is connected to the rotating shaft of the first vibration damping ring 21, the second vibration damping ring 22 can be rotated counterclockwise downward to install the compressor body 1 on the arc-shaped support plate 25 on the first vibration damping ring 21, and then the second vibration damping ring 22 can be rotated clockwise upward to make the arc-shaped support plate 25 on the second vibration damping ring 22 also fit the compressor body 1; at this time, the fixing rod 33 is rotated clockwise and placed on the base 31, and then the fixing knob 34 is rotated to fix the position of the second vibration damping ring 22 and the first vibration damping ring 21. When the compressor body 1 vibrates, the force generated by the vibration will be transmitted to the buffer ring 24, and then fed back to the spring 23 by the buffer ring 24. The elastic force of the spring 23 will offset the impact force generated by the vibration, thereby protecting the compressor body 1.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
