Abstract
The utility model provides a connection structure of cistern, it is shown like figure. 1-3, including cistern and compressor housing, set up the cistern iron pipe on the cistern, set up no reduction iron pipe on the cistern iron pipe, the cistern iron pipe passes through the welding of second flange together with no reduction iron pipe, set up the compresser cylinder in the compressor housing, set up the hole on the compresser cylinder, the last third flange that still sets up of compressor housing, set up the bump on the second flange, the electric current is convenient for concentrate by the bump when resistance welds, set up the bump on the third flange, the electric current is convenient for concentrate by the bump when resistance welds.
Description
Technical field
The utility model belongs to refrigeration accessory technical field, specifically relates to a kind of syndeton of liquid reservoir.
Background technology
Tube connector etc. in prior art on the bend pipe of giving vent to anger of sump assemblies, compressor case adopts copper pipe usually, and by high silver solder gas brazing or the welding manner such as high-frequency induction brazing or the soldering of argentiferous phos copper Manual flame.Because copper pipe and slice weldering, gas brazing mode etc. are with high costs, and this original connected mode needs to adopt multiple welding, therefore cause welding cost high, consume the energy mainly with and the slip of sump assemblies higher.
Summary of the invention
The utility model mainly solves the technical problem existing for above-mentioned prior art, a kind of syndeton of liquid reservoir is provided, by changing the escape pipe of original copper material into centreless grinding iron pipe, and adopt special second Flange joint, the method for attachment of sump assemblies and compressor body is welded and slice welds and changes electric resistance welding into by original flame.Therefore the cost of raw material only needs about 1/3 of original connected mode, and decreases twice naked light welding and a procedure; In quality, the welding of naked light flame welding has the slip of 100PPM, and resistance-welding process only has the slip of 1PPM, greatly improves the welding quality of product, and product appearance and cleannes also improve a lot.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of syndeton of liquid reservoir, comprise liquid reservoir and compressor housing, described liquid reservoir is arranged liquid reservoir iron pipe, described liquid reservoir iron pipe arranges centreless grinding iron pipe, and described liquid reservoir iron pipe and centreless grinding iron pipe pass through together with the second flange welding; In described compressor housing, compresser cylinder is set, described compresser cylinder arranges endoporus; Described compressor housing also arranges three-flange.
As preferably, described second flange arranges salient point, when described salient point is convenient to electric resistance welding, concentrates electric current.
As preferably, described three-flange arranges salient point, when described salient point is convenient to electric resistance welding, concentrate electric current.
As preferably, described centreless grinding iron pipe external diameter is processed through centerless grinder, and outer surface precision is higher, and outer diameter tolerance controls
As preferably, described compresser cylinder bore inner diameter is processed through centerless grinder, and inner surface accuracy is higher, and id tolerance controls
The beneficial effect that the utility model has: by changing the escape pipe of original copper material into centreless grinding iron pipe, and adopt special second Flange joint, makes the method for attachment of sump assemblies and compressor body be welded by original flame and slice welds and changes electric resistance welding into.Therefore the cost of raw material only needs about 1/3 of original connected mode, and decreases twice naked light welding and a procedure; In quality, the welding of naked light flame welding has the slip of 100PPM, and resistance-welding process only has the slip of 1PPM, greatly improves the welding quality of product, and product appearance and cleannes also improve a lot.Therefore the utility model has the features such as structure is simple, reasonable in design.
Accompanying drawing explanation
Fig. 1 is a kind of structure chart of the present utility model.
Fig. 2 is a kind of structure chart of the utility model second flange.
Fig. 3 is a kind of structure chart of the utility model three-flange.
In figure: 1, liquid reservoir; 2, liquid reservoir iron pipe; 3, the second flange; 4, three-flange; 5, endoporus; 6, centreless grinding iron pipe; 7, compresser cylinder; 8, compressor housing; 10, salient point.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of syndeton of liquid reservoir, as shown in Figures 1 to 3, comprise liquid reservoir and compressor housing, described liquid reservoir is arranged liquid reservoir iron pipe, described liquid reservoir iron pipe arranges centreless grinding iron pipe, and described liquid reservoir iron pipe and centreless grinding iron pipe pass through together with the second flange welding; In described compressor housing, compresser cylinder is set, described compresser cylinder arranges endoporus; Described compressor housing also arranges three-flange; Described second flange arranges salient point, when described salient point is convenient to electric resistance welding, concentrates electric current; Described three-flange arranges salient point, when described salient point is convenient to electric resistance welding, concentrates electric current; Described centreless grinding iron pipe external diameter is processed through centerless grinder, and outer surface precision is higher, and outer diameter tolerance controls
described compresser cylinder bore inner diameter is processed through centerless grinder, and inner surface accuracy is higher, and id tolerance controls
During welding, first centreless grinding iron pipe, liquid reservoir iron pipe and the second flange slice are welded together, then three-flange and compressor housing electric resistance welding are welded together, finally centreless grinding iron pipe is installed in compresser cylinder endoporus, and the second flange and three-flange electric resistance welding are welded together; By changing the escape pipe of original copper material into centreless grinding iron pipe, and adopting special second Flange joint, the method for attachment of sump assemblies and compressor body being welded by original flame and slice welds and changes electric resistance welding into.Therefore the cost of raw material only needs about 1/3 of original connected mode, and decreases twice naked light welding and a procedure; In quality, the welding of naked light flame welding has the slip of 100PPM, and resistance-welding process only has the slip of 1PPM, greatly improves the welding quality of product, and product appearance and cleannes also improve a lot.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
