Description
Technical field
The utility model relates to compressor field, especially a kind of compressor and inlet pipe connection thereof.
Background technology
At present idle call compressor is to adopt inlet pipe connection assembly (or claim inlet pipe connection, again or claim seat ring)Connect the housing of reservoir and compressor. This inlet pipe connection assembly is mainly by iron hoop and copper ring two parts groupBecome, iron hoop and copper ring are fixed by the mode of furnace brazing. Conventionally, compressor producer first passes through iron hoopThe pressure welding of inlet pipe connection assembly, on the housing of compressor, then is welded the bend pipe of reservoir by flameMode is welded in the copper ring of inlet pipe connection assembly.
Fig. 1 is the structural representation of the first inlet pipe connection in prior art, as shown in Figure 1, this enterThe welding of the housing of gas tube connector and compressor is the mode that adopts outer pressure welding. Fig. 2 is in prior art secondPlant the structural representation of inlet pipe connection, as shown in Figure 2, the housing of this inlet pipe connection and compressorThe mode of pressure welding in welding adopts. By contrast, from structure, the iron hoop 101 of the first inlet pipe connectionLength is shorter, and copper ring 102 length are longer, so relative the second inlet pipe connection slightly high on cost.In above-mentioned the first and the second inlet pipe connection assembly, copper ring 102 all needs interference fit with iron hoop 101,And conventionally adopt the mode of furnace brazing. The cost that adopts furnace brazing to weld is higher, and due to air-conditioningCompressor leakage rate requires high (normally PPM level), thereby the requirement of welding quality is also higher, instituteManagement and production cost with manufacturer are higher. Meanwhile, in follow-up use procedure, iron hoop 101 needsCarry out resistance pressure-welding with the housing of compressor, copper ring 102 need carry out flame welding with the bend pipe of reservoir.The weld defect of connecting pipe component soldering part is subject to can fully manifesting after above-mentioned heat affecting, thereby causes micro-letting outLeak.
For solving above-mentioned leakage problem, there is producer to propose the structure of the third inlet pipe connection, be commonly referred toBandaid tubular type sample, as shown in Figure 3, the matrix of this third inlet pipe connection is low carbon steel pipe, low carbon steel pipeOn there is copper plate 103, adopt the mode of copper coating to solve flame welding follow-up and copper pipe. This styleCan avoid above-mentioned leakage problem, but copper coating can, to environment, be unfavorable for environmental protection. And,For ensureing the stability of copper plate, very strict to copper-plating technique stability requirement accordingly. Although the thirdThe housing pressure welding of inlet pipe connection and compressor does not have problems, only can be disposable but weld with reservoir copper pipeWelding, replacing that cannot corresponding compressor liquid storage device.
