Description

A kind of scroll type air compressor

Technical field

The utility model relates to a kind of air compressor, particularly a kind of scroll type air compressor.

Background technique

Existing scroll type air compressor, as application number be 201120143080.8 and the Chinese patent of 201120143104.X as described in scroll type air compressor, the suction valve that its intakeport is installed, be common one-way valve, see Fig. 1, this suction valve only allows air-flow unidirectional movement, during namely this scroll type air compressor work, due to the effect of negative pressure, the piston of suction valve is opened, as Fig. 1 a, air after filtration sucks and coils by movable orbiting scroll and quiet whirlpool the compression chamber complementing each other to form through suction valve, along with movable orbiting scroll moving relative to quiet whirlpool dish, compression chamber also changes its volume in corresponding movement, thereby complete air-breathing, compression, the pressurized air process of exhaust, when this scroll type air compressor is shut down, the piston of suction valve is closed, as Fig. 1 b, air in compression chamber can not be discharged through suction valve.Because suction valve only has opening and closing two states, therefore assemble the scroll type air compressor of this suction valve, can only carry out work (namely load operating) and shut down two actions, cannot meet the no-load running of actual demand.When this scroll type air compressor is shut down, suction valve cuts out, air in compression chamber can not be discharged through suction valve, the pressure of the gas that is compressed to half in each compression chamber is different, namely the interior pressure of machine is unbalanced, this unbalanced interior pressure-volume easily causes compressor reverse rotation, can directly affect the working life of machine; When this scroll type air compressor is shut down; in oil gas tank, pressure must be unloaded and be put; in order to unload the interior pressure of the gas tank of draining the oil; must on oil gas tank, add handling and put valve; by unloading, put valve gas in tank is unloaded and put; if directly discharge the gas in oil gas tank, can produce very large noise, therefore must install silencing apparatus additional to alleviate harsh noise.Adopt above-mentioned two kinds gas in oil gas tank is unloaded to the mode of putting, not only many one operational sequences, have also increased user cost.

Existing scroll type air compressor, the anti-Moving plate free-wheeling system of scroll type air compressor as described in the application number Chinese patent that is 201220128199.2, part is more, structure is more complicated, it is also more difficult to load and unload, cost of production is higher, scroll type air compressor described in the Chinese patent that and for example application number is 200910209386.6, its anti-rotation mechanism is by cross slip-ring, movable orbiting scroll and support composition, see Fig. 2 a, Fig. 2 b and Fig. 2 c, the structure schematic diagram that wherein Fig. 2 b is movable orbiting scroll, Fig. 2 c is the structural representation of cross slip-ring, protruding key a and groove a on cross slip-ring match, protruding key b and groove b on cross slip-ring match, the rigidity of this cross slip-ring is poor, in using process, easily produce bending, distortion, working life is shorter, and process the special frock clamping of the essential making of this cross slip-ring, a pair of protruding key a on processing cross slip-ring, during with protruding key b on cross slip-ring another side, to carry out multiple clamping, more during machining work consuming, remove material also more, not only cost is higher, and be not easy realize produce in enormous quantities.

[0004]existing scroll type air compressor, its main frame lubricating and cooling system is shown in Fig. 3, during machine work, main oil circuit is divided into branch road a and branch road b after entering main frame.Branch road a lubricating bearings c12 ＇, then through oil circuit e, export the intakeport that is back to main frame; Branch road b by the through hole a on the dish of quiet whirlpool and the little branch road of through hole b two to quiet whirlpool coil, movable orbiting scroll carries out cooling and lubricating, then by through hole c and the little branch road of through hole d two, bearing a10 ', bearing b11 ＇ carried out to cooling and lubricating.The deficiency that this lubricating and cooling system exists is: one, through hole a and through hole b lead to two different compression chamber inside, because the interior pressure of these two compression chambers is different, can make the oil of main oil circuit can not be distributed in equably through hole a and the little branch road of through hole b two, thereby affect the lubrication effect of quiet whirlpool dish, movable orbiting scroll; Two, through hole c and through hole d two ramuscule roads ejections is not lubricant oil but the gas mixture that forms in compression chamber, therefore can not effectively bearing a10 ', bearing b 11 ＇ be lubricated, also can increase the interior pressure at movable orbiting scroll back simultaneously, reduce the working life of distal portion oil sealing.Described in the Chinese patent that and for example application number is 201020215393.5, there is above-mentioned deficiency in the main frame cutting oil oil channel structures of scroll type air compressor too.For another example application number be 201010523165.9 and the application number Chinese patent that is 201210259934.8 described in the lubricating and cooling system that more generally uses such as scroll type air compressor, adopt built-in oil line structure, because oil circuit is placed in frame, oil circuit hole is elongated, bring difficulty to processing, cleaning oil circuit, also make the form structure of frame more complicated,, there is above-mentioned deficiency in this built-in oil line structure too.
