Description
Technical field
The utility model relates to compressor field, particularly relates to
OnePlant compressor suction duct.
Background technique
Compressor, be that a kind of low-pressure gas is promoted is the fluid machinery of pressurized gas, 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 suction tude, after cylinder compresses it, from the refrigerant gas of outlet pipe discharge High Temperature High Pressure, for refrigeration cycle provides power, thus the refrigeration cycle of realization compression → condensation → expansion → evaporation.Because in system's operation process, can't guarantee that refrigeration agent can vaporize fully at evaporation stage, having liquid refrigeration agent for fear of the refrigeration agent that comes out from vaporizer enters cylinder and causes liquid hammer, need between cylinder and vaporizer, liquid-storage container be set, cylinder mainly is communicated with by the compressor suction duct assembly with liquid-storage container, and the compressor suction duct assembly comprises pipe in compressor air suction outer tube and the compressor air suction.
General whole copper pipe or the copper facing pipe of adopting of pipe in traditional compressor air suction outer tube and the compressor air suction, and the compressor air suction outer tube adopts silver solder gas brazing or high frequency brazing to be welded on the housing of compressor, the method not only makes the processing cost height, but also can produce great amount of carbon dioxide because using scolder, so that befouling environment; Concrete, adopt the bearing capacity of gas brazing joint of above-mentioned tape welding material relevant with joint junction surface size.Therefore, methods such as gas brazing certainly will need to adopt that lap joint and external member are spliced are to increase joint junction surface area, to remedy the deficiency of soldering strength, but also can produce great amount of carbon dioxide because using scolder, so that befouling environment, the above-mentioned compressor outlet pipe causes cost to improve because adopting a large amount of copper materials simultaneously.Adopt above-mentioned high frequency brazing, its electrical efficiency is lower, and operating voltage is too high, and Security is relatively poor, fragility is bigger, and is easy to crack, and working life is short, and air-conditioning producer is when welding again, cause the secondary fusion of scolder easily, make inferior quality, be not easy to the welding of outlet pipe in the compressor field.
Notification number is that the Chinese utility model patent of CN 202215860 U discloses " the air-breathing outer tube on a kind of air condition compressor ", its technological scheme comprise " comprise copper inner sleeve (1) and iron outer sleeve (2), described iron outer sleeve (2) welding is sheathed on copper inner sleeve (1) outside; The tube wall (3) of described iron outer sleeve (2) bottom is the capable setting of the Eight characters to the outer exhibition, make tube wall (3) with along being the setting of α angle between the exhibition portion tube wall (4), the α angle is 80-160 ° of angles." copper pipe of this air-breathing outer tube and the Placement between the iron pipe be after the socket again by being welding along exhibition portion of splayed shape setting, so just caused the complexity of linkage structure between copper pipe and the iron pipe; And, because copper pipe and iron pipe are the stove weldering (may also be referred to as is caulk weld) excessively of socket joint type, when welding, vibration and cracking can be produced, industry can not be satisfied for the requirement of the clean dynamics of copper pipe, and when air-conditioning producer welds again, cause the secondary fusion of scolder easily, make inferior quality; Moreover, because copper pipe and iron pipe are the Spielpassung of socket joint type, filled scolder in the gap before welding, the welding back also will be carried out weld defects and detect for being prevented defectiveness between weld seam.Simultaneously, also because having used scolder, not environmental protection becomes.
To sum up, for the cost pressure that alleviates compressor manufacturer and the complexity of avoiding the structure of pipe in compressor air suction outer tube and the compressor air suction and the CO 2 waste gas problems such as pollution to environment, research and develop a kind of simple in structure, the production process environmental protection, compressor suction duct cheap for manufacturing cost has very far-reaching and significant meaning.
