Description
Technical field
The utility model relates to the technical field of membrane compressor, relates to particularly a kind of integrated part of cylinder block of membrane compressor of single cylinder 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 part is many and cost is high, arrange difficulty is installed.
Summary of the invention
The utility model purpose be to provide a kind of take up room little, sealing surface is few, the operation maintenance is convenient, part is few, the integrated part of cylinder block of membrane compressor of more compact structure, low cost of manufacture, single cylinder lid that discharge capacity is large.
To achieve these goals, the utility model adopts following technological scheme: the integrated part of cylinder block of membrane compressor of this single cylinder lid, it comprises a cylinder cap, left cylinder, right cylinder body, left cylinder, right cylinder body is connected to the left and right sides of cylinder cap by fastening piece, between left cylinder and cylinder cap, be provided with left diaphragm, between right cylinder body and right cylinder cap, be provided with right diaphragm, form left air cavity between left diaphragm and the cylinder cap, form left oil pocket between left diaphragm and the left cylinder, form right air cavity between right diaphragm and the cylinder cap, form right oil pocket between right diaphragm and the right cylinder body, left air cavity and right air cavity are communicated with admission line by first passage, left air cavity and right air cavity are communicated with exhaust duct by second channel, left oil pocket, right oil pocket is communicated with oil supply pipeline respectively.
When oil supply pipeline during to left and right the oil pocket fuel feeding, the oil in the left and right oil pocket drives diaphragm, and left and right air cavity volume-variation during the diaphragm resiliently deformable realize that the gas in the left and right air cavity compresses and conveying simultaneously, thereby air displacement is multiplied.Like this in the situation that only adopt a cylinder cap, two cylinder bodies just can reach the original air displacement that needs to adopt two cylinder caps, two cylinder bodies, a piston, thus take up room little, sealing surface is few, the operation maintenance is convenient, part is few, more compact structure, low cost of manufacture.
