Description
Technical field
The present invention relates to the technical field of membrane compressor, relate to a kind of integrated part of cylinder block of membrane compressor of single cylinder lid particularly.
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 made up 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 up to 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 big discharge capacity, just need break through from structure so will realize the big 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 big discharge capacity by two cylinder bodies of three passbands.The membrane compressor of this structure takes up room greatly, and sealing surface is many, and operation maintenance inconvenience, is arranged difficulty is installed the many and cost height of part.
Summary of the invention
The object of the invention 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 big.
To achieve these goals, the present invention 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 side diaphragm and the cylinder cap, form left oil pocket between left side 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 side air cavity and right air cavity are communicated with admission line by first passage, left side air cavity and right air cavity are communicated with left oil pocket with exhaust duct by second channel, right oil pocket is communicated with oil supply pipeline respectively.
When oil supply pipeline during to left and right 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.Under the situation that only adopts a cylinder cap, two cylinder bodies, just can reach the original air displacement that need to adopt two cylinder caps, two cylinder bodies, a piston like this, thus take up room little, sealing surface is few, the operation maintenance is convenient, part is few, more compact structure, low cost of manufacture.
