Description
Technical field
The utility model relates to the syndeton of a kind of cooling system knockout and compressor, belongs to knockout syndeton technical field.
Background technology
The cooling system of the refrigerating plants such as air-conditioning is mainly by the liquid reservoir connecting in turn, knockout and compressor form, in conjunction with Fig. 1, knockout is mainly by upper end cover 2a, middle cylinder body 3a and bottom end cover 4a form, in installation process, upper end cover 2a place connects by air inlet pipe 1a and liquid reservoir, bottom end cover 4a place passes through escape pipe 5a(also referred to as " liquid reservoir bend pipe 5a ") connect with compresser cylinder hole 8a, air inlet pipe 1a, upper end cover 2a, middle cylinder body 3a, bottom end cover 4a, after escape pipe 5a and cylinder-bore 8a are communicated with smoothly, only at large parts as middle cylinder body 3a and upper end cover 2a, between bottom end cover 4a, adopt stove sealed with brazing, and between air inlet pipe 1a and upper end cover 2a, between bottom end cover 4a and escape pipe 5a, all adopt brass solder sealing, welding between escape pipe 5a and cylinder-bore 8a is more loaded down with trivial details: because cylinder-bore 8a is positioned at compressor case 9a, during welding, need first by taper copper pipe 6a(also referred to as " cylinder tube connector 6a ") be pressed in cylinder-bore 8a, for transition, connect, after gas brazing is closely knit, at compressor case 9a place flame welding, connect copper pipe 7a(also referred to as " shell copper pipe 7a " again), finally escape pipe 5a is inserted to taper copper pipe 6a, now, be followed successively by from outside to inside compressor case 9a, shell copper pipe 7a, cylinder-bore 8a, cylinder tube connector 6a and escape pipe 5a, by compressor case 9a, shell copper pipe 7a, cylinder tube connector 6a and liquid reservoir bend pipe 5a carry out gas brazing simultaneously, by liquid reservoir, knockout and compressor hold together, the defect that above-mentioned syndeton exists is:
(1) junction of each transition conduit such as liquid reservoir, air inlet pipe 1a, upper end cover 2a, middle cylinder body 3a, bottom end cover 4a, escape pipe 5a, compressor case 9a, cylinder-bore 8a and cylinder tube connector 6a all needs to carry out multiple welding, especially: air inlet (copper) pipe and liquid reservoir, (copper) pipe of giving vent to anger even all need to add transition conduit with compressor and assist naked light to weld between bottom end cover and escape pipe, complex operation, complex structure, manufacturing cost is higher, is unfavorable for producing.
(2) because each connecting portion is all welded by open-flam soldering (brass solder, gas brazing), in welding process, the heated time of knockout is long, in knockout escape pipe, air inlet pipe and middle cylinder body, all can produce a large amount of oxide skin, impurity also increases thereupon, increased the resistance in separatory passage, the inequality of having aggravated separatory.
(3) cooling system of employing prior art moulding, each knockout only can be applicable to a kind of liquid reservoir and compressor of model specification, thereby compatibility is poor.
Utility model content
In order to overcome the above-mentioned connection complexity, the irregular defect of separatory that exist in prior art, the utility model provides a kind of cooling system knockout easy to process, simple for structure and the syndeton of compressor.
For achieving the above object, the technical scheme that the utility model is taked is as follows:
The syndeton of cooling system knockout and compressor, comprise knockout and compressor, knockout comprises air inlet pipe, upper end cover, middle cylinder body, bottom end cover and escape pipe, described knockout escape pipe interference fit is pressed into the cylinder-bore of compressor, the first flange is sleeved between escape pipe and compressor case, adopts welding manner that the first flange is connected with compressor case and escape pipe.
For realizing better result of use, further arranging of technique scheme is as follows:
Described interference fit refers to that escape pipe carries out precision truing processing, and its external diameter is controlled at cylinder-bore internal diameter and differs 0.005-0.01mm, to coordinate interference to install.Preferably, the external diameter of escape pipe, compared with the large 0.01-0.005mm of the internal diameter of cylinder-bore, is directly squeezed into escape pipe in cylinder-bore, and pressurization can adopt the mechanical systems such as hydraulic pressure, punching press to carry out.
Described welding adopts the non-naked light mode of electric resistance welding or slice weldering.Preferably, can first the first flange and escape pipe be welded to one welding by slice, then the first flange and compressor case are adopted to electric resistance welding.
Between described escape pipe and bottom end cover, by the second flange, be connected, between the second flange and escape pipe, bottom end cover, adopt electric resistance welding or stove brazing mode to be connected.Preferably, the second flange adopts slice weldering and escape pipe to be welded to connect together with the first flange, can one-shot forming, save operation, and between the second flange and bottom end cover, adopt electric resistance welding.
The syndeton of knockout and compressor in the cooling system of employing technique scheme gained, its operation principle and beneficial effect are as follows:
(1) between the cylinder-bore of escape pipe and bottom end cover, escape pipe and compressor, all adopt flange to be connected, the first flange adopts the mode of interference fit to be pressed into cylinder-bore, component surface fineness is higher, avoided the use of transition conduit, in the effect of guaranteeing to be tightly connected, the cost that has also reduced manufacturing procedure, transition fitting drops into.
Between (2) first flanges, the second flange and escape pipe, all adopt the mode of slice weldering to be connected, this integral type welding manner can greatly be accelerated working (machining) efficiency, and between the first flange and compressor case, the second flange and bottom end cover, all adopt electric resistance welding, because the slice weldering and the electric resistance welding that adopt are non-naked light welding manner, non-naked light welding manner can be avoided forming oxide skin in the separatory pipelines such as middle cylinder body, bottom end cover, escape pipe, guarantee separatory passage circulate, be conducive to the interior gas-liquid mixed of knockout even.
(3) in the syndeton that the utility model adopts, transition fitting is few, welding sequence is few, all less to pipeline and compressor injury, its flange connection adopting can be changed fast, easily, just can realize the replacing of compressor and the liquid reservoir of different model, thereby application is comparatively flexible, both can meet the user demand of different processing occasions, improved again the service efficiency of the parts such as knockout.
