Abstract
The utility model relates to a three-segment type air-inlet connecting pipe for a compressor. The three-segment type air-inlet connecting pipe is used for connecting an air-cylinder air suction hole, an air-suction race and a liquid-storage elbow and is of a three-segment type structure, wherein the outer diameter of a first segment is smaller than the hole diameter of the air-cylinder air suction hole, the outer diameter of the second segment is in interference fit with the air-cylinder suction hole, and the outer diameter of the third segment is in clearance fit with the air-suction race. Compared with the prior art, the utility model structurally ensures that when the air-inlet connecting pipe is pressed in, centers of the air-suction hole, the air-inlet connecting pipe and a pressure head are coaxial as much as possible so as to reduce the conditions of single-side stress during pressing-in of the air-inlet connecting pipe and connecting pipe falling in a subsequent procedure in a batch production process.
Description
Technical field
The utility model relates to a kind of compressor assembly, especially relates to a kind of compressor and uses the 3 stops inlet pipe connection.
Background technique
What the rotary compressor fit was comparatively general has two kinds, specific as follows:
Fit one: housing hot jacket [with stator] → pump assembly input → inlet pipe connection [or lined duct] is pressed into → and lower cover is pressed into → three spot welding [six spot welding] → lower cover circumference weldering →;
Fit two: stator and pump assembly prepackage → housing hot jacket → inlet pipe connection [or lined duct] be pressed into → three spot welding [six spot welding] →.
As shown in Figure 1, in the existing design, common inlet pipe connection 4 generally all is designed to two-part, the suction port interference fit of diameter little a section and cylinder 1, one section and air-breathing seat ring 2 Spielpassung that diameter is big.Under the perfect condition; When common inlet pipe connection 4 is pressed into; The center of the suction port of cylinder 1 and common inlet pipe connection 4 and pressure head 3 coexists on the axis, can guarantee that at this moment the outer wall of common inlet pipe connection 4 and suction port hole wall interference fit get better, and sealing is guaranteed.
But in the practical set process; Because common inlet pipe connection 4 is pressed into front case and the pump housing not welding as yet, and has certain clearance between upper cylinder cover [or cylinder] external diameter and the housing internal diameter, so upper cylinder cover [or cylinder] can rotate in housing; Carry out common inlet pipe connection 4 and be pressed into this moment; Because the spigot shaft coaxle degree of suction port center and common inlet pipe connection 4 and pressure head 3 relatively poor [especially fit two, lower cover welded when making owing to frame set, can't fix the pump housing behind the hot jacket]; Monolateral stressed when causing connecting tube to be pressed into easily; Cause the sealing state variation of itself and suction port, cause when serious that inlet pipe connection comes off in the subsequent handling, as shown in Figure 2.
The model utility content
The purpose of the utility model is exactly to provide a kind of compressor that reduces monolateral stressed situation to use the 3 stops inlet pipe connection in order to overcome the defective that above-mentioned existing technology exists.
The purpose of the utility model can realize through following technological scheme:
A kind of compressor is used inlet pipe connection; Be used to connect cylinder suction port, air-breathing seat ring and liquid-storage container bend pipe; Be three stage structure; First section external diameter is slightly less than the aperture of cylinder suction port, the suction port interference fit of second section external diameter and cylinder, the 3rd section external diameter and air-breathing seat ring internal diameter Spielpassung.
Described first section length is desirable greater than 0 arbitrary value, but effect can be better during greater than 1.0mm.
First section, second section and the 3rd section of this connecting tube is coaxial configuration.
Compared with prior art; When the utility model guarantees that from structure inlet pipe connection is pressed into; Suction port, inlet pipe connection and pressure head three's center is coaxial as far as possible, to reduce in the batch production process monolateral stressed situation about coming off with later process connecting tube when inlet pipe connection is pressed into.
Description of drawings
Fig. 1 is the mounting structure schematic representation of common inlet pipe connection;
Fig. 2 is the pressurized schematic representation of common inlet pipe connection;
Fig. 3 is the structural representation of the utility model;
Fig. 4 is the mounting structure schematic representation of the utility model.
Among the figure, 1 for cylinder, 2 to be second section, 53 be the 3rd section for 3 stops inlet pipe connection, 51 is first section, 52 for common inlet pipe connection, 5 for pressure head, 4 for air-breathing seat ring, 3.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of compressor is with 3 stops inlet pipe connection 5; Its structure is as shown in Figure 3, is three stage structure, and first section 51 external diameter is slightly less than the aperture of cylinder suction port; The suction port interference fit of second section 52 external diameter and cylinder 1, the 3rd section 53 external diameter and air-breathing seat ring 2 Spielpassung.First section length can be set arbitrarily, but effect can be better during greater than 1.0mm.First section 51, second sections 52 and the 3rd sections 53 of connecting tube is coaxial configuration.
The utility model in the compressor assembly process, carries out before inlet pipe connection is pressed in use; First section 51 less manual in advance prepackage of diameter gets into the suction port of cylinder 1, and be as shown in Figure 4, can guarantee the coaxial of suction port and connecting tube 5 like this; And then carry out connecting tube and be pressed into, monolateral stressed situation in the time of can effectively improving connecting tube and be pressed into, first section 51 length is long more; Then both coaxalitys are good more, and it is also good more that connecting tube is pressed into state.
The problem that piece of writing head is described has been run into by Rili Electric Appliance Co Ltd, Shanghai in CSA series compressor assembly process, after adopting newly-designed inlet pipe connection, significantly improved the monolateral stressed connecting tube obscission that causes when inlet pipe connection is pressed into.
