Description
Technical field
The utility model relates to a kind of technical field of membrane compressor, relates to particularly a kind of integrated part of cylinder block of membrane compressor with single cylinder twin-tub lid.
Background technique
Membrane compressor has ad hoc diaphragm because of it, and compressed gas was gained the name with extraneous the separation.Membrane compressor also claims " diaphragm type compressor ".In the membrane compressor, the function of cylinder is finished by a film chamber.The cavity that so-called film chamber is comprised of the cylinder cap with vaulted profile and oil distribution casing (or cylinder body), the diaphragm periphery is fastened between cylinder cap and the oil distribution casing (or cylinder body).When the diaphragm deflection deformation, the volume in the film chamber changes thereupon, plays the effect that sucks and compress, and the folded cavity of cylinder cap and diaphragm is air cavity, and the folded cavity of oil distribution casing (or cylinder body) and diaphragm is oil pocket.Because the film chamber does not need to lubricate, sealing is fine, and gas does not contact with any oiling agent, so the clarity of pressurized gas is high, is specially adapted to compression, conveying or the bottling of some precious rare gas.In addition, for strong, poisonous, the explosive gas of corrosivity, also should adopt diaphragm type compressor.The pressure range that diaphragm type compressor can provide is wider, can be from very low pressure until 200MPa, it is widely used in experimental research department of petrochemical industry, Coal Chemical Industry, metallurgy, defence and military, Aero-Space, new energy, nuclear power, gas filling and modern science and technology etc.
Diaphragm is the vital part of membrane compressor, the size of diaphragm raw material size has determined the overall dimensions that the single cylinder body of membrane compressor can be accomplished, also just limited the membrane compressor design of large discharge capacity, just need to break through from structure so will realize the large discharge capacity of membrane compressor.
At present, membrane compressor commonly used is single piston twin-rotor housing structure, and it comprises a piston, a threeway, two cylinder bodies, two cylinder caps, and a piston reaches the demand of large discharge capacity by two cylinder bodies of three passbands.The membrane compressor of this structure takes up room greatly, and sealing surface is many, operation maintenance inconvenience, and in the backhaul of piston two cylinder caps the not in running order utilization ratio of membrane compressor that causes is low.And can only realize single stage compression, just also need a piston, two cylinder bodies, two cylinder caps if realize two stage compression.
Summary of the invention
The utility model purpose is to provide a kind of always has cylinder cap in running order and increase operation rate, can realize single-stage or two stage compression, more compact structure, low cost of manufacture, the integrated part of cylinder block of membrane compressor that sealing surface is few, the operation maintenance has single cylinder twin-tub lid easily in each stroke of piston.
To achieve these goals, the utility model adopts following technological scheme: this integrated part of cylinder block of membrane compressor with single cylinder twin-tub lid, it comprises cylinder body, upper cylinder cover, lower cylinder cap, piston, upper oil distribution casing, lower oil distribution casing, upper cylinder cover, lower cylinder cap is connected to cylinder body by fastening piece, piston side-to-side movement and cylinder body is divided into left chamber and right chamber in the cylinder body that is filled with oil, upper at cylinder body, lower surface is respectively equipped with oil distribution casing, lower oil distribution casing, between upper cylinder cover and upper oil distribution casing, be provided with upper diaphragm, between lower cylinder cap and lower oil distribution casing, be provided with lower diaphragm, form upper gas chamber between upper diaphragm and the upper cylinder cover, form upper oil cavitie between upper diaphragm and the upper oil distribution casing, form lower air chamber between lower diaphragm and the lower cylinder cap, form lower oil cavitie between lower diaphragm and the lower oil distribution casing, left chamber or right chamber one is communicated with upper oil cavitie and another of left chamber or right chamber is communicated with lower oil cavitie.
When piston during to left movement, the oil in the left chamber of cylinder body is pressed into lower oil cavitie or the upper oil cavitie that is communicated with it through the piston promotion, thereby drive the gas in diaphragm compression lower air chamber or the upper gas chamber, when piston moves right, the oil in the right chamber of cylinder body is pressed into upper oil cavitie or the lower oil cavitie that is communicated with it through the piston promotion, thereby drive the gas in diaphragm compression upper gas chamber or the lower air chamber, so just realized always having in each stroke (left and to the right) of piston cylinder cap in running order and increase operation rate; Just can not realize two stage compression simultaneously when the area of upper diaphragm and lower diaphragm, just realize single stage compression when identical; Owing to cancelled threeway and a cylinder cap, so more compact structure, low cost of manufacture, sealing surface is few, the operation maintenance is convenient.
