Abstract
The utility model relates to compressors, and provides a compressor shell body which is reasonable in structure and good in tightness. The compressor shell body comprises an upper cover, a cylinder body and a bottom cover. Two ends of the cylinder body are respectively connected with the upper cover and the bottom cover, and a sealing cavity is formed. A first through hole which is used for installation of an electric joint is formed in the cover top of the upper cover. A support cap is installed in the first through hole in an embedded mode. A second through hole is further formed in the upper cover. An output tube nozzle is installed in the second through hole in an embedded mode. A third through hole is formed in the wall of the cylinder body. An input tube nozzle is installed in the third through hole in an embedded mode. The compressor shell body is reasonable in structural design, good in the tightness, and particularly applicable to a small size refrigeration compressor.
Description
Technical field
The utility model relates to Compressor Technology, particularly finger pressure contracting engine housing.
Background technique
The refrigerant of traditional air-conditioning system mostly is R22, is meet the requirement of environmental protection, and the R410a of new cooling media is promoted in air-conditioning system.Yet the working pressure of refrigerant R410a thus, is had higher requirement to the sealing of compressor housing far above refrigerant R22.Because the housing internal pressure is larger, if the sealing of housing is inadequate, the security incident such as can leak, break.
The model utility content
The utility model proposes a kind of compressor housing, it is rational in infrastructure, good airproof performance.
The technical solution of the utility model is achieved in that a kind of compressor housing, it comprises loam cake, cylindrical shell and bottom, the two ends of described cylindrical shell form Seal cage with described loam cake and bottom welding respectively, offer the first through hole at described loam cake caping, in the first through hole, embed the holder cap that is provided with for the mounting electrical joint, also offer the second through hole covering, in the second through hole, embed the output ozzle is installed, wall at described cylindrical shell offers third through-hole, is embedded at third through-hole the input ozzle is installed.
The beneficial effects of the utility model are: by loam cake, cylindrical shell and the bottom Seal cage that is welded, can assemble the parts such as bent axle of compressor in the chamber, the sealing that welding can the Reliable guarantee joint.The holder cap is set covering, electrical connector is installed in can be so that easy to assembly in the holder cap; At housing input ozzle and output ozzle are set, it is used for connecting suction tude and the steam outlet pipe of dredging working medium, is convenient to be connected and sealed.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the cross-sectional view of the utility model compressor housing.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of compressor housing, as shown in Figure 1, a kind of compressor housing, it comprises loam cake 1, cylindrical shell 2 and bottom 3, the two ends of described cylindrical shell 2 form Seal cage with described loam cake 1 and bottom 3 welding respectively, offer the first through hole at described loam cake 1 caping, in the first through hole, embed the holder cap 4 that is provided with for the mounting electrical joint, on loam cake 1, also offer the second through hole, in the second through hole, embed output ozzle 5 is installed, wall at described cylindrical shell 2 offers third through-hole, is embedded at third through-hole input ozzle 6 is installed.
Convenient for parts such as bent axle that compressor inside is installed, the pump housings, the housing main structure is taked loam cake 1, cylindrical shell 2 and bottom 3 forms, and is convenient when assembly, after installing, again with loam cake 1 and bottom 3 and cylindrical shell 2 seal weldings.As compressor, its action is refrigeration agent, and refrigeration agent enters the compressed rear discharge of compressor.Another main points of the technical program are to be respectively arranged with the ozzle that refrigeration agent imports and discharges---are input ozzle 6 and output ozzle 5 successively, can convenient be connected with output tube with the supplying tube of refrigeration agent.
When the compressor internal pressure was higher, at first easily the position of distortion or leakage was the installation position of perforate position, especially electrical connector, and as shown in Figure 1, electrical connector specifically can be wire board assembly 7.The technical program is provided with holder cap 4, and holder cap 4 directly is connected easily with loam cake 1 than wire board assembly 7 with the degree of difficulty that is connected of loam cake 1, and wire board assembly 7 is connected with holder cap 4 again.
Specifically, described holder cap 4 can be round basin type, and from the holder cap 4 open-mouths formation edge that stretches out, it is to be convenient to and loam cake 1 welding that the edge is set.Described holder cap 4 bottoms offer fourth hole, and the tenminal block of wire board assembly 7 lower ends passes this hole, stretch into compressor housing and are connected with the compressor internal cable.Can also add sealing compound holder cap 4 is interior, with further assurance wire board assembly 7 and sealing and the soundness of asking cap 4 to be connected.
Argon arc welding is a kind of welding commonly used, soundness and good airproof performance after its welding, therefore, described output ozzle 5 and loam cake 1, and described input ozzle 6 all can adopt argon arc welding with cylindrical shell 2.
It is that the steel of 00Cr19Ni10 forms that described loam cake 1, cylindrical shell 2, bottom 3, holder cap 4, output ozzle 5 and input ozzle 6 all can adopt the GB trade mark, this kind steel is as a kind of Austenitic Stainless Steel, its better mechanical property can satisfy the pressure requirement of compressor housing; And be difficult for getting rusty, can avoid the rapid corrosion of parts to cause compressor housing to leak.
Be corroded for avoiding compressor housing to be in the corrosive environment, the outer surface of compressor housing can be carried out acid wash passivation, also can remove simultaneously because the oxide layer that welding causes.After acid wash passivation was complete, the compression case surface can form passivating layer, and it has etch-proof effect.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
