Description
Technical field
The present invention relates to compressor field.
Background technique
The present invention is the manufacture method of relevant scroll compressor and scroll compressor, the assembling method of gas outlet pipe, pressure cover and the upper housing of the relevant scroll compressor of more detailed finger and the scroll compressor that utilizes assembling method to make.
Compressor is the compression energy that mechanical energy is converted to compressible fluid generally speaking, is divided into reciprocal operation type, eddy type, centrifugal and blade type usually.
Scroll compressor is different from the straight-line reciprocal operation form of utilizing piston, is to utilize the swiveling body of center of circle form or blade shape to compress discharge gas.
Fig. 1 is the longitudinal section that shows existing scroll compressor.
Illustrating existing scroll compressor comprises: the casing 10 that possesses gas suction pipe (SP) and gas outlet pipe 80, the inner peripheral surface of casing 10 is fixing separately main structure 2 and the auxiliary structure (not shown) in both sides up and down, the drive motor 3 of assembling between main bearing 2 and the supplementary bearing (not shown), be pressed into the center of drive motor 3 and connect the running shaft 4 that the rotating force of drive motor 3 is passed in main bearing 2 backs, be combined in running shaft 4 and be placed on the top movable orbiting scroll 5 of main bearing 2, be fixed on the top static vortex disk 6 of main bearing 2 in order to combine and form a plurality of pressing chambers with movable orbiting scroll 5, be combined in the back side of static vortex disk 6 and the internal separation of casing 10 is sucked the pressure cover 70 in nip territory and discharge nip territory, be combined in the hardboard portion back side of static vortex disk 6 and prevent to discharge the reverse valve assembly body 8 of the adverse current of gas.
In addition, casing 10 is by the lower casing 10a by dress drive portion and main bearing 2, and the top upper housing 10b that is combined in lower casing 10a and is arranged on pressure cover 70 constitutes.
Existing scroll compressor carries out following action, the power supply of connecting causes that running shaft 4 is with drive motor 3 revolutions, movable orbiting scroll 5 is turned round by eccentric distance, meanwhile form a plurality of pressing chamber p between blade part 5a, the 6a between movable orbiting scroll 5 and the static vortex disk 6, this pressing chamber P is that the circumnutation of the persistency of movable orbiting scroll 5 causes the process that reduces volume and pressurized gas in the moving process of center.
At this moment, the pressurized gas part of the normal exhaust port 6f periphery in service of compressor flow into the inboard of blade by the gas gap between blade front end and blade space groove 5c, the 6c front end and the base plate face of the blade space groove 5c, the 6c that join therewith between and release blade, blade is compressed the 5b of hardboard portion, 6b plane one side that gas is released whirlpool, opposite dish, prevents that from then on pressurized gas from leaking between the plane.
Below, the associated methods of scroll compressor discharge portion is described.
Fig. 2 and Fig. 3 are by the illustrated drawing of stage difference the associated methods of discharge portion.
As illustrating among Fig. 2, upper housing 10b is arranged to overburden pressure lid 70, inserts in the exhaust port 12 of upper housing 10b and has fixed gas outlet pipe conduit 11.Gas outlet pipe conduit 11 is that the part 13 that gas outlet pipe 11 contacts with upper housing 10b is welded fixedly upper housing 10b.Weld best circumferential section integral body and carry out the line welding the part 13 of contact.
Illustrate among Fig. 3, gas outlet pipe 80 is to make with the material of plastically deformable, is pressed in the exhaust port 72 and gas outlet pipe conduit 11 that is arranged on pressure cover 70.
After being pressed into, fixing with the part 14 places welding that contacts of gas outlet pipe conduit 11 at gas outlet pipe 80.
But gas outlet pipe 80 is pressed into the distortion that the manufacture method that is arranged on pressure cover and upper housing 1b may cause upper housing 1b, and leaking may appear in poorly sealed between pressure cover 70 and the gas outlet pipe 80, causes the efficient of compressor to reduce.
Summary of the invention
Technical problem to be solved by this invention is, the manufacture method of a kind of scroll compressor and scroll compressor is provided, and prevents the inefficiency of the compressor that the distortion of upper housing causes.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the manufacture method of scroll compressor comprises that the gas outlet pipe that inserts fixed gas discharge tube one end in the exhaust port of pressure cover is in conjunction with the stage, the other end of gas outlet pipe inserts the gas outlet pipe conduit and makes upper housing be arranged on the pressure upper part of the cover casing assembling stage by the inner side surface of upper housing, discharge the soldered elements of the soldered elements that inserts cylindrical shape between conduit and the gas outlet pipe in conjunction with the stage at gas, the welding stage of the part that part that the welding gas discharge tube contacts with soldered elements and welding gas discharge conduit contact with soldered elements.
The manufacture method of described scroll compressor, gas outlet pipe is the position that the inlet of welding fixation pressure lid exhaust port contacts with gas outlet pipe in conjunction with the stage
Described scroll compressor is the scroll compressor of making according to above-mentioned scroll compressor manufacture method.
The invention has the beneficial effects as follows: the present invention is weldingly fixed on gas outlet pipe on pressure cover and the upper housing, prevents because of upper housing is pressed into the distortion that causes, prevents efficient low of compressor.
And gas outlet pipe is to carry out the line welding with pressure cover, also carries out the line welding with the gas outlet pipe guide rod, and double seal prevents the leakage of gas.
