Wherein negative electrode is positioned at the suction hole of case inside, the 3rd flange is placed at the suction hole of the hull outside, positive electricity
Pole presses from the outside of housing towards the 3rd flange, is powered the 3rd flange welding in the outside of housing；
(2) compressor bank is installed whole；
(3) the first mounting O-shaped rings on the detent of iron pipe, have then been completed the insertion of iron pipe Jing suction holes
In compression case body, and it is further inserted in compresser cylinder hole.
(4) second flange is attached with the 3rd flange by electric resistance welding；Whole compression during due to welding sump assemblies
Machine installation, so during using electric resistance welding sump assemblies, electrode cannot be placed in housing, if by negative electrode
It is clamped in the outer surface of housing, then electric current can be made not concentrate and cannot weld.Therefore the 3rd flange on the outside of suction hole is negative electricity
Pole provides the position of clamping, and during welding, negative electrode holds the 3rd flange tightly, and anelectrode is from the outside of second flange towards the second method
Orchid pressure；After energization, to carrying out electric resistance welding between second flange and the 3rd flange；So as to complete sump assemblies and compressor housing
Connection.
Preferably, arrange salient point in the second flange, the welding of the salient point and tapered slope of the prior art
Surface is compared, and is prevented from affecting welding when centreless grinding formed pipe is not coaxial with cylinder-bore, can more neatly adjust welding table
Docking mode between face and compressor case, it is to avoid accurate alignment and must easily let out when face of weld is tapered slope
The problem of leakage.
Preferably, arrange salient point on the 3rd flange, the welding of the salient point and tapered slope of the prior art
Surface is compared, and is prevented from affecting welding when centreless grinding formed pipe is not coaxial with cylinder-bore, can more neatly adjust welding table
Docking mode between face and compressor case, it is to avoid accurate alignment and must easily let out when face of weld is tapered slope
The problem of leakage.
The device have the advantages that：By the way that the escape pipe of original copper material is changed to into iron pipe, and set on iron pipe
Some O-rings are put, and is connected using special second flange, make the method for attachment of sump assemblies and compressor body by original fire
Flame is welded and slice weldering is changed to electric resistance welding.Therefore the cost of raw material only needs to 1/3 or so of original connected mode, and reduces two
Secondary naked light welding and one procedure；The welding of naked light flame welding has the slip of 100PPM in quality, and resistance-welding process only has
The slip of 1PPM, greatly improves the welding quality of product, also improves a lot in product appearance and cleannes.

Specific embodiment
Below by embodiment, and accompanying drawing is combined, technical scheme is described in further detail.
Embodiment：A kind of method of attachment of sump assemblies, as shown in figures 1-4, including liquid reservoir and compressor housing, institute
Setting liquid reservoir iron pipe is stated on liquid reservoir, iron pipe is set on the liquid reservoir iron pipe, the liquid reservoir iron pipe and iron pipe are by the
Two flange weldings together, arrange some detents on the iron pipe, on the detent O-ring is arranged；The compression
Compresser cylinder is set in casing body, the 3rd flange is set on the compressor housing.
A kind of method of attachment of sump assemblies is comprised the following steps：
(1) at the suction hole on the outside of the compressor housing of non-installing machine core on weld the 3rd flange with electric resistance welding mode；
Wherein negative electrode is positioned at the suction hole of case inside, the 3rd flange is placed at the suction hole of the hull outside, positive electricity
Pole presses from the outside of housing towards the 3rd flange, is powered the 3rd flange welding in the outside of housing；
(2) compressor bank is installed whole；
(3) the first mounting O-shaped rings on the detent of iron pipe, have then been completed the insertion of iron pipe Jing suction holes
In compression case body, and it is further inserted in compresser cylinder hole.
(4) second flange is attached with the 3rd flange by electric resistance welding；Whole compression during due to welding sump assemblies
Machine installation, so during using electric resistance welding sump assemblies, electrode cannot be placed in housing, if by negative electrode
It is clamped in the outer surface of housing, then electric current can be made not concentrate and cannot weld.Therefore the 3rd flange on the outside of suction hole is negative electricity
Pole provides the position of clamping, and during welding, negative electrode holds the 3rd flange tightly, and anelectrode is from the outside of second flange towards the second method
Orchid pressure；After energization, to carrying out electric resistance welding between second flange and the 3rd flange；So as to complete sump assemblies and compressor housing
Connection；Salient point is set in the second flange, the salient point compared with the face of weld of tapered slope of the prior art, energy
Welding is affected when enough preventing centreless grinding formed pipe not coaxial with cylinder-bore, can more neatly be adjusted outside face of weld and compressor
Docking mode between shell, it is to avoid must accurate alignment and the easy problem of leakage when face of weld is tapered slope；Institute
State and salient point is set on the 3rd flange, the salient point is prevented from nothing compared with the face of weld of tapered slope of the prior art
Welding is affected when reduction formed pipe is not coaxial with cylinder-bore, can more neatly be adjusted between face of weld and compressor case
Docking mode, it is to avoid must accurate alignment and the easy problem of leakage when face of weld is tapered slope.
The method of attachment of sump assemblies by the escape pipe of original copper material by being changed to iron pipe, and if arranging on iron pipe
Dry O-ring, and connected using special second flange, the method for attachment of sump assemblies and compressor body is made by original flame welding
Connect and be changed to electric resistance welding with slice weldering.Therefore the cost of raw material only needs to 1/3 or so of original connected mode, and reduces bright twice
Fire welding and one procedure；The welding of naked light flame welding has the slip of 100PPM in quality, and resistance-welding process only has 1PPM
Slip, greatly improve the welding quality of product, also improve a lot in product appearance and cleannes.
Finally it is pointed out that above example is only the more representational example of the present invention.It is clear that the invention is not restricted to
Above-described embodiment, can also there is many deformations.Any letter that every technical spirit according to the present invention is made to above example
Single modification, equivalent variations and modification, are considered as belonging to protection scope of the present invention.
