Description
[technical field]
The present invention relates to have the positive displacement pump or the compressor field of slide plate, more particularly, relate to a kind of penetration type slip sheet mechanism that is applied to positive displacement compressor or decompressor.
[background technique]
Sliding-vane compressor is mainly used in minitype air conditioner refrigeration plant and the motorcar air conditioner at present, and it attracts attention with advantage such as simple in structure, easy to manufacture, that pressure pulsation is little, vibration is little.The sliding-vane compressor main structure comprises body, three parts such as rotor and slide plate are formed, and rotor is the parts of unique continuous operation, the groove that has several to cut along its length above, wherein be inserted with the slide plate that can slide on oil film, rotor rotates in the stator of cylinder.During rotation, centrifugal force throws away slide plate from groove, forms independent one by one pressing chamber.Rotation constantly reduces the volume of pressing chamber, and air pressure constantly increases, and controls the heat that compression produces by injecting compressed oil, and high-pressure air is discharged from relief opening, and wherein residual oil is removed by final oil separator.Rotor rotates a circle, and its unit volume is from leading to mutually to the steam-expelling port steam discharge with suction port, will experience by minimum to become gradually greatly, again the Changing Pattern that is diminished gradually by maximum.Thereby finish processes such as expansion, air-breathing, compression, exhaust.
The penetration type slide plate is made up of positive and negative two slide plates, compares with compressor sliding blade commonly used, and its slide plate is thick, stressed advantage such as big.Just slide plate is blocked up, and the centrifugal force that penetration slipping sheet is stretched to both sides is bigger, and the slide plate of stretching, extension directly contacts with stator inner wall, no matter is to contact with line or contact with face, all can not reduce the friction between slide plate and the stator inner wall.The quality of penetration slipping sheet is what times of slide plate in the slide vane compressor commonly used, and what doubly (quality of penetration slipping sheet and friction are directly proportional with the multiple of common slide vane compressor) its friction also is.The slide plate of penetration slipping sheet is to be contained in the groove of rotor to slidably reciprocate, since be the slide plate that slides, certainly exist the gap between slide plate and the rotor recesses, this gap is the direct access between high pressure and the low pressure, the height of slide plate is multiply by in the gap, be exactly the area that leaks, this gap is without any protective measures.When pressure reached 0.5m pa, leakage rate had surpassed velocity of sound, and under the effect of rotating force and leak pressure, the outer side surface of penetration slipping sheet and the inboard of rotor rollaway nest produce friction, cause power loss.The penetration slipping sheet compressor is still to rest on preliminary developing stage, not enough maturation till now.
For example: Chinese utility model patent ZL95100939.7 discloses the patent of a kind of " slide plate of positive displacement pump or compressor " by name, the main following technology of its technological scheme is formed: " slide plate (1) has two kinds of one chip and penetration type biplate combined types; at diameter of stator bore surface or the rotor diameter surface contacted end of slide plate (1) with pump or compressor; a floating seal bar (2) is arranged " ... " thickness of slide plate (1) is made stepped shaft " ... " between rotor (26) and the bearing (21); an elasticity compression ring (2) is arranged, the material of elasticity compression ring (2) has metal or polyurethane elastomer or rubber or plastics etc. to make " ...The purpose that floating seal bar (2) is set be " make the contacted end of slide plate and diameter of stator bore or rotor diameter; become the face contact by line contact; thus can reduce the contact stress of slide plate and diameter of stator bore greatly, and the usability and the life-span of raising pump that can be bigger or compressor ".
There is following some major defect in technique scheme: A. floating seal bar is processed by cylindrical body, the circular arc that equates with diameter of stator bore is cut in about 30% place, arc length is the length of sealing, and the surface of contact of floating seal bar and stator inner wall increases, and has also increased the area of friction simultaneously.The sub-fraction that cut on the opposite is oil storage, even floating seal bar translation-angle also can make oil circuit unimpeded.B. slide plate is formed by positive and negative two, utilizes centrifugal force that slide plate is stretched to both sides.Because the centrifugal force of slide plate is too big, practices well be with the thickness of slide plate do thin a bit, reduce the slide plate quality and reduce friction.C. between rotor and the slide plate without any sealing, fluid can leak from the crack between rotor and the slide plate, or directly pushed by fluid, and the frictional force of rotor and slide plate is increased, and influence slide plate mobile in rotor, and causes heat and power loss.
China utility model patent ZL200520101607.5 discloses the patent of a kind of " a kind of rotary positive displacement compressor " by name, the main following technical characteristics of its technological scheme is formed: " a kind of rotary positive displacement compressor; it comprises the cylinder that two ends are tightly connected with end cap (12); cylinder is provided with liquid; aspiration import (2) and exhaust port (11); be provided with the main shaft (3) of two ends with the bearing supporting in the cylinder; drive realization liquid by main shaft, aspiration advances and discharges, it is characterized in that eccentric setting of described main shaft and cylinder and motive sealing combine, be provided with the chute (8) that equates with the cylinder number in the main shaft, be provided with in the chute with its motive sealing can be toward the slide block (5) of polyslip, slide block is provided with gas pressure relief slot (7), the slide block end contacts with the cylinder bore motive sealing, makes the cylinder inner chamber be separated into hyperbaric chamber (9) and low-pressure cavity (4); On exhaust port (11), be provided with simultaneously the open and close valve (1) that is tightly connected ".
Equally there is similar problem: A in technique scheme with Chinese utility model patent ZL95100939.7.Slide block is that face contacts with the surface of contact of stator inner wall, has increased friction area, causes bigger heat and power loss.Without any sealing, fluid can leak from the crack between rotor and the slide plate, or directly pushed by fluid between B rotor and the slide plate, and the frictional force of rotor and slide plate is increased, and influences slide plate moving in rotor, and causes heat and power loss.
