Described the first metal section and described the second metal section are the dissimilar metal pipeline section.Can be the copper pipe section with described the first metal section in the present embodiment, described the second metal section be the iron pipe section.
with described air-breathing inner tube, described outlet pipe, described suction tude and described steam outlet pipe subsection setup, be set to the copper pipe section being connected the part that needs copper with the outside, all the other pipeline sections can be set to other lower metal section combination of cost of material, can reduce the use amount of copper like this, reduced the cost of compressor pipe fitting, thereby finally make the holistic cost of compressor be well controlled, adopt simultaneously the docking welding between pipeline section, operate simple and easy and need not to increase the auxiliary welding block of extra welding etc., simultaneously can not produce the CO 2 waste gas befouling environment in production process, above-mentioned so-called docking welding is namely that butt end with the butt end of described the first metal section and described the second metal section is mutually to supporting, here be different from the mode of socket, the mode of only having docking to arrange, the welding effect of two metal sections in guarantee the present invention, welding quality is good, and weld simple and easy, need not to increase welding block.
The second metal section 41 of described outlet pipe is connected with described compressor housing 1 by resistance welding, the second metal section 71 of described air suction outer tube is connected with described compressor housing by resistance welding, the second metal section 51 of described suction tude is connected by the shell of resistance welding with liquid-storage container 2, and the second metal section 61 of described steam outlet pipe is connected by the shell of resistance welding with liquid-storage container 2.Not only technique is simple to adopt the method, and has omitted scolder, further reduces manufacture cost.
In butt-welded described the second metal section, the butt end of described the first metal section is concordant setting with the butt end of described the second metal section or is to tilt to be equipped with described first metal section of arbitrary group with it.
The butt end of described the first metal section is concordant setting with the butt end of described the second metal section, can directly the first metal section or the second metal section directly be cut off by cutting equipment in production process and get final product, can not cause the waste of material, be convenient to simultaneously manufacture.
And, the butt end of the butt end of the first metal section and described the second metal section is to tilt to be equipped with as described, can increase the area of contact between described the first metal section and described the second metal section, increase friction, make the better effects if of friction welding.And this angle of inclination preferably is set to become with the pipe fitting direction 80 degree～90 degree.
At described first metal section of arbitrary group with it in butt-welded described the second metal section, the internal diameter of the butt end of described the first metal section is less than the external diameter of the butt end of described the second metal section, and the external diameter of the butt end of described the first metal section is greater than the internal diameter of the butt end of described the second metal section; Can be also that described first metal section of arbitrary group is with it in butt-welded described the second metal section, the internal diameter of the butt end of described the second metal section is less than the external diameter of the butt end of described the first metal section, and the external diameter of the butt end of described the second metal section is greater than the internal diameter of the butt end of described the first metal section.
Therefore, in the present embodiment compressor preferably, at arbitrary group of described the first metal section with it in butt-welded described the second metal section, the internal diameter of the butt end of described the second metal section equals the internal diameter of the butt end of described the first metal section, and the external diameter of the butt end of described the second metal section equals the external diameter of the butt end of described the first metal section, the identical area that can take full advantage of the docking end face in docking operation of the thickness of pipe of described the first metal section and described the second metal section, be convenient to welding, improve welding quality.
Concrete, air-breathing inner tube described in the present embodiment compressor, described air suction outer tube, described outlet pipe, described suction tude and described steam outlet pipe can also include respectively the multistage metal section, carry out segmentation with the user demand according to reality.
Concrete, the first metal section described in the present embodiment compressor can be the metal section of the same race of metal section of the same race or different thicknesss of pipe wall from described the second metal section, selects pipeline section with the use according to reality, is finally the purpose of saving cost for reaching.
The pipe fitting of above-mentioned compressor, namely the manufacturing concrete steps of described air-breathing inner tube, described air suction outer tube, described outlet pipe, described suction tude and described steam outlet pipe are as follows:
A. clamp: described first metal section of arbitrary group and described the second metal section are individually fixed in rolling clamp and movable clamp;
