Embodiment three
Embodiment one defines under four kinds of different situations with embodiment two, and jet channel 8 is offered the scope of puff prot on upper flange, and present embodiment three provides concrete setting scheme in a kind of puff prot position and air injection enthalpy-increasing process thereof.As shown in Figure 6; In order to express the position of relative slide plate 7 of the puff prot of being offered and intakeport 21 better; Among the figure with mode intuitively in the upper end of cylinder 2 the drawn position at jet channel 8 places of direct with dashed lines, and the position at a puff prot 811 places that had of jet channel 8.In order to let puff prot 811 in time open, increase the enthalpy amount, puff prot 811 can be set to the half moon shape, also can adopt circular puff prot.
In conjunction with Fig. 6 to Fig. 9; The air injection enthalpy-increasing process of the compressor that embodiment three provides is following: 1. roller 6 peaks are through slide plate 7, and during no show intakeport 21 right hand edges 211, air aspiration cavity is in suction condition; The interior gas pressure of compression chamber this moment is lower, and puff prot 811 is in closed condition; 2. bent axle 5 drive rollers 6 are rotated counterclockwise; When roller 6 peaks pass through intakeport 21 right hand edges 211; Puff prot 811 is progressively opened, inject high pressure, high enthalpy gas (because slide plate 7 separates compression chamber and air aspiration cavity, the gas that spray enthalpy this moment can not influence normal suction) in compression chamber; 3. bent axle 5 drive rollers 6 continue to be rotated counterclockwise, and puff prot 811 is all opened, and the puff prot area increases, and gas pressure improves constantly in the compression chamber simultaneously; 4. bent axle 5 continuation drive rollers 6 are rotated counterclockwise; Gas pressure improves constantly in the compression chamber, and when the progressively approaching spray enthalpy of gas pressure in compression chamber pressure, puff prot 811 is closed gradually; The compression intracavity gas begins to discharge to compressor through flange, repeats afterwards 1. extremely 4..
In the present embodiment, the particular location of said puff prot need be provided with according to spray enthalpy pressure, and the puff prot position is the closer to slide plate, and puff prot is opened more lately, and it is big more that puff prot can be done, and requires spray enthalpy pressure also high more; Puff prot is offered the position the closer to the air-breathing low pressure chamber of cylinder, and puff prot is opened more early, and spray enthalpy effect is obvious more, but the puff prot area that can design is more little.For the area that increases puff prot can adopt half moon shape puff prot, adopt powder metallurgy flange and the dividing plate can the rheo-die-casting moulding, do not need to process.To increase the enthalpy amount and can on upper and lower flange and dividing plate, process simultaneously and increase the enthalpy hole in order to improve.As adopt the puff prot of non-one-way valve, after spray enthalpy set positions, system need adjust the secondary structure of damming, and makes spray enthalpy pressure be higher than puff prot and closes front air cylinder compression chamber pressure, avoids spraying enthalpy and flows backwards.As adopt the puff prot of one-way valve, then need not consider backward flow problem.
Embodiment four
Embodiment four is with embodiment three difference: shown in figure 10, jet channel 8 has been offered first puff prot 801 and second puff prot 802 on upper flange, and present embodiment also is provided with an one-way valve at second puff prot, 802 places.
In conjunction with Figure 10 to Figure 13; The air injection enthalpy-increasing process of the compressor that embodiment three provides is following: 1. roller 6 is through intakeport 21 right hand edges 211; The interior gas pressure of compression chamber this moment is lower; (this moment, second puff prot 802 also was in closed condition), inject high pressure, high enthalpy gas in compression chamber are progressively opened in 801 beginnings of first puff prot; 2. bent axle 5 drive rollers 6 are rotated counterclockwise, and begin compression compression intracavity gas, and gas pressure improves constantly, and first puff prot 801 continues the spray enthalpys, and second puff prot 802 is progressively opened and begun to compression chamber inject high pressure, high enthalpy gas; 3. bent axle 5 drive rollers 6 continue to be rotated counterclockwise, and gas pressure further improves in the compression chamber, before the compression chamber internal pressure is higher than first puff prot, 801 pressure, closes first puff prot 801 through roller 6 end faces, avoids increasing enthalpy and flows backwards; When the compression chamber internal pressure was not higher than second puff prot, 802 pressure as yet, second puff prot 802 continues to increase enthalpy to compression chamber, and was suitable up to pressure, during this period of time because second puff prot, 802 places are provided with one-way valve structures, can not cause equally to increase the enthalpy refluence; 4. bent axle 5 drive rollers 6 continue to be rotated counterclockwise; Second puff prot 802 will progressively be closed; First puff prot 801 and second puff prot 802 were in closed condition all the time after exhaust was accomplished, and closed next circuit compression chamber until roller 6, repeated afterwards 1. extremely 4..
Among the embodiment four,, cause spray enthalpy pressure also to change and change along with operating conditions because air-conditioning system running environment can change; In order to improve spray content; Can avoid spraying enthalpy again and flow backwards, so adopt two above puff prots, two puff prots can be progressively opened, successively closed in the roller rotation.The morning that first puff prot 801 is opened, the also morning of closing, inner pressure of air cylinder is less when opening, and it is better to increase the enthalpy effect, but first puff prot 801 is positioned at the tip of the scope of offering, and is difficult to do big; The ratio that second puff prot 802 is opened is later, close also than later, and spray enthalpy pressure is bigger, is positioned at the middle part of the scope of offering, and can do bigger.Pressure when embodiment four both can guarantee that first puff prot 801 is closed in the compression chamber does not reach puff prot pressure, increases the enthalpy amount in order to improve again, prolongs and increases the enthalpy time, utilizes second puff prot 802 to continue to increase enthalpy up to closing.But in order to prevent to flow backwards, second puff prot 802 initiatively is provided with one-way valve.
Above embodiment is merely fully open and unrestricted the present invention it is understandable that: just above-mentioned jet channel and puff prot are arranged on lower flange and the twin-tub dividing plate, and its principle is identical with above embodiment with working procedure; In addition, also can offer fumarole at upper and lower flange, dividing plate simultaneously in order to increase the enthalpy amount.In addition, because the beginning air injection enthalpy-increasing needs a period of time to the enthalpy gases affect that increases that spirt goes to air-breathing, so in the actual production, puff prot can be opened in the edge in embodiment one and embodiment two said zones, also can not influence air-breathingly, and the enthalpy amount is sprayed in increase simultaneously.
