Description
Technical field
The present invention relates to compressor field, particularly relate to a kind of compressor and manufacture method thereof and application.
Background technology
Compressor, it it is a kind of fluid machinery that low-pressure gas is promoted to gases at high pressure, it it is the heart of refrigeration system, the enclosure interior of compressor is provided with cylinder, and during work, the refrigerant gas of low-temp low-pressure enters cylinder from air inlet pipe, after it is compressed by cylinder, discharge the refrigerant gas of High Temperature High Pressure from exhaustor, provide power for kind of refrigeration cycle, thus realize the kind of refrigeration cycle of compression → condensation → expansion → evaporation.
Due in system operation process, it is impossible to ensure that cold-producing medium can completely vaporize at evaporation stage, enter cylinder cause liquid hammer in order to avoid having the cold-producing medium of liquid from vaporizer cold-producing medium out, need between cylinder and vaporizer, arrange reservoir.
Compressor liquid storage device, is used for storing coolant, and compressor liquid storage device Main Function includes that realizing air-liquid separates, and removes foreign body, also carries out the control of recirculating oil quantity.
Existing compressor case and liquid reservoir shell typically use ferrous material to make, and how to be welded to form by least two parts.Due to compressor in the running, the vibration of axial cyclic will be there is, and the part of its most fragile will be welding position, and compressor and reservoir are all fully closed, in order to ensure that coolant and lubricating oil do not leak, compressor case and liquid reservoir shell must have good welding quality, therefore the intensity and quality to welding position has strict demand, and otherwise during vibration of compressor, welding position easily occurs crackle to cause leakage.
The Chinese invention patent of the applicant's early stage application Publication No. CN102699504A discloses " the open manufacture method of a kind of compressor liquid storage device ", its technical scheme includes that " reservoir has sealing dissolved samples and is combined on sealing dissolved samples connection welded pipe within sealing dissolved samples; described sealing dissolved samples uses ferrous material to make; described welded pipe uses copper plated material or copper material to make, and welding between welding and sealing dissolved samples with the welded pipe of described sealing dissolved samples self is both the solderless resistance welding of employing and realizes." this liquid reservoir shell includes the cylinder of a hollow, and be bonded respectively to upper end cover and the bottom end cover at cylinder two ends, the combination between cylinder and up and down end cap uses solderless resistance welding.This welding method requires that the welding ends of each ingredient of this reservoir must be provided with flange, welding between each ingredient is the welding of its flange surface, increase these flanges and be to ensure that quality and the intensity of welding, in case welding position generation crackle causes leakage during vibration of compressor, but add usage amount and the weight of material the most simultaneously, cause manufacturing cost to improve, and be easier to around the nugget of welding ends form angle, cause the tensile strength of solder side and fatigue strength relatively low.The welding process of above-mentioned electric resistance welding is first to apply upsetting force (10～15MPa), the butt welding face making workpiece is in close contact, electrified regulation is to mecystasis, then upsetting force (30～50MPa) is applied, power-off simultaneously, makes weldment contact position produce plastic deformation under stress and seam.This resistance welding is normally only used for the workpiece that weld diameter is less than 20mm, cross section is simple and stress is little, although operating easier, but the processing of butt-welding fitting end face and cleaning require higher, contact surface heating otherwise can be caused uneven, produce oxide be mingled with, the defect such as not weld penetration；And also lacking reliable lossless detection method at present, welding quality can only lean on the destructive testing of technique sample and workpiece to check.
It is faced with huge cost pressure instantly in compressor manufacturer, it is provided that one has a manufacturing cost relative moderate, and the technology of the high compressor case of welding quality and the compressor of liquid reservoir shell and manufacture method thereof is particularly important.
