Flange.
A kind of connection method of device for storing liquid comprises 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 set is installed whole；
(3) the first mounting O-shaped rings on the detent of iron pipe, then insert what is be completed by iron pipe through suction hole
In compression case body, and it is further inserted into compresser cylinder hole.
(4) second flange is attached with the 3rd flange by argon arc welding；The tungsten electrode diameter of argon arc welding：1~2mm, weldering
Connect electric current：10~100A, straight polarity direct current：4~5L/min, exchanges 6~8L/min.
Preferably, salient point is set in the second flange, the salient point and the welding of tapered slope of the prior art
Surface is compared, and can prevent that influence is welded when centreless grinding formed pipe and not coaxial cylinder-bore, can more neatly adjust welding table
Docking mode between face and compressor case, it is to avoid accurate alignment and must easily be let out when face of weld is tapered slope
The problem of leakage.
Preferably, salient point is set on the 3rd flange, the salient point and the welding of tapered slope of the prior art
Surface is compared, and can prevent that influence is welded when centreless grinding formed pipe and not coaxial cylinder-bore, can more neatly adjust welding table
Docking mode between face and compressor case, it is to avoid accurate alignment and must easily be 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 into iron pipe, and set on iron pipe
Some O-rings are put, and using the connection of special second flange, make the connection method of device for storing liquid and compressor body by original fire
Flame is welded and slice weldering is changed to argon arc 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 a procedure；The welding of naked light flame welding has 100PPM slip in quality, and resistance-welding process only has
1PPM slip, greatly improves and is also improved a lot in the welding quality of product, product appearance and cleannes.
