Problems solved by technology

[0003] The existing sound-absorbing cover sealing structure basically uses metal copper gaskets as the intermediate sealing material. Due to the high price of metal copper and the increase in the price of raw materials, the cost of the enterprise has increased sharply. It is necessary to seek structural design and material application that can replace metal raw materials and achieve the same effect. A way to seal the effect is imminent

Embodiment 1

[0045] Embodiment one, such as Figure 4 Shown:

[0046] The present invention improves the sound-absorbing cover, cancels the copper washer screw and improves the cylinder block, that is: the compressor sealing and sound-absorbing structure of the present invention, the outer end of the through hole of the fastening screw 2 is installed on the described sound-absorbing cover 1, and the sealing boss 1.2 is set.

[0047] The invention overcomes the disadvantages of the prior art, and adopts the method of canceling the copper washer and improving the sound-absorbing cover, the screw and the cylinder seat to realize the purpose of reducing the cost and realize the requirement of effective sealing. The cost of the existing sound-absorbing fastening structure is reduced, and the technical index required by the compressor fastening process is met.

[0048] In order to achieve a close fit between the boss sealing surface and the lower plane of the nut of the fastening screw 2, and t...

Embodiment 2

[0069] In order to further improve the sealing effect of the sound-absorbing structure, on the basis of the first embodiment above, a high-temperature-resistant sealant is provided between the annular sealing surface of the sealing boss 1.2 and the screw pressing surface 2.3 of the fastening screw 2. Layer 5.

[0070] The high-temperature-resistant sealant is polymerized by high-performance heat-resistant resin and various heat-resistant materials. Good quality and other characteristics. Generally, a sealant resistant to 350°C is used, which is made of basic resin, high-purity filler, electronic-grade reactive diluent, advanced additives, and processing aids, which are made by mechanical mixing and vacuum treatment.

[0071] In order to achieve the purpose of the invention of the sealing structure of the exhaust high-pressure chamber of the compressor described in Embodiment 2, the present invention also provides an assembly method of the sealing and noise-absorbing structure...

Embodiment 3

[0077] Embodiment three, such as Figure 7 Shown:

[0078] In order to further improve the sealing performance of the compressor sound-absorbing sealing structure, simplify the structure, and reduce production costs, the present invention also provides another bolt-free compressor sealing and sound-absorbing structure, and its technical solution is:

[0079] The compressor includes a cylinder block 3 and a sound-absorbing cover 1, and the sound-absorbing cover 1 is pressed into the seam of the cylinder block 3 to form a tight fit; Coating of high temperature sealants.

Abstract

The invention discloses an assembling method for a sealing and silencing structure of a compressor. The compressor comprises a cylinder seat (3) and a silencing cover (1), and the silencing cover (1) is installed on the cylinder seat (3) through a fastening screw (2); and a sealing boss (1.2) is arranged at the outer end of a through hole for mounting the fastening screw (2) on the silencing cover (1). By adopting the technical scheme, the structure is simple; and manufacturing and using cost is greatly reduced, stability and reliability are achieved, the sealing effect is better, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of sound-absorbing and sealing structures of compressors, and relates to the sealing structure of an exhaust high-pressure chamber of a compressor. The invention also relates to its assembly method. Background technique [0002] The sealing structure of the high-pressure cavity of the cylinder block used at this stage is to place the copper gasket on the fastening screw, and the exhaust muffler cavity is placed on the high-pressure cavity of the cylinder block. The contact surface is formed, and the better metal ductility of the copper washer is used to form a seal between the upper part of the sound-absorbing cover and the screw through the downward fastening force, and finally achieve the purpose of fastening the sound-absorbing cavity without air leakage. [0003] The existing sound-absorbing cover sealing structure basically uses metal copper gaskets as the intermediate sealing material. Due to the high...
