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 with single cylinder multi-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.
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 can only be to two cylinder cap effects.
Summary of the invention
The integrated part of cylinder block of membrane compressor with single cylinder multi-cylinder lid that the utility model purpose is to provide a kind of more compact structure, low cost of manufacture, sealing surface is few, the operation maintenance is convenient, realize modular design and layout.
To achieve these goals, the utility model adopts following technological scheme: this integrated part of cylinder block of membrane compressor with single cylinder multi-cylinder lid, it comprises cylinder body, oil distribution casing, n cylinder cap, many siphunculus with n+1 passage, wherein n is the integer more than or equal to 2, each cylinder cap is connected to cylinder body by fastening piece, oil distribution casing is between cylinder cap and cylinder body, between cylinder cap and oil distribution casing, be provided with diaphragm, form air cavity between diaphragm and the cylinder cap, form oil pocket between diaphragm and the oil distribution casing, a channel connection oil supply pipeline and other passage of many siphunculus are communicated with respectively an oil pocket.
When the passage of oil supply pipeline by many siphunculus during to each oil pocket fuel feeding, the oil in the oil pocket drives diaphragm, and each air cavity volume-variation during the diaphragm resiliently deformable realize that the gas in each air cavity compresses and conveying simultaneously, thereby air displacement is multiplied.So more compact structure, low cost of manufacture, few, the operation maintenance convenience of sealing surface; And can require to design and arrange cylinder cap according to user's process parameter.
Description of drawings
Fig. 1 is the structural representation according to a preferred embodiment of the integrated part of cylinder block of membrane compressor with single cylinder multi-cylinder lid of the present utility model;
Fig. 2 is the structural representation according to another preferred embodiment of the integrated part of cylinder block of membrane compressor with single cylinder multi-cylinder lid of the present utility model.
Embodiment
Shown in Fig. 1-2, this integrated part of cylinder block of membrane compressor with single cylinder multi-cylinder lid, it comprises cylinder body 1, oil distribution casing 7, n cylinder cap 2, many siphunculus 3 with n+1 passage, wherein n is the integer (n=2 among Fig. 1 more than or equal to 2, n=3 among Fig. 2), each cylinder cap is connected to cylinder body 1 by fastening piece, oil distribution casing is between cylinder cap and cylinder body, between cylinder cap and oil distribution casing, be provided with diaphragm 4, form air cavity 5 between diaphragm and the cylinder cap, form oil pocket 6 between diaphragm and the oil distribution casing, a channel connection oil supply pipeline and other passage of many siphunculus are communicated with respectively an oil pocket.
When the passage of oil supply pipeline by many siphunculus during to each oil pocket fuel feeding, the oil in the oil pocket drives diaphragm, and each air cavity volume-variation during the diaphragm resiliently deformable realize that the gas in each air cavity compresses and conveying simultaneously, thereby air displacement is multiplied.So more compact structure, low cost of manufacture, few, the operation maintenance convenience of sealing surface; And can require to design and arrange cylinder cap according to user's process parameter.
Preferably, be assigned to equably on the diaphragm in order to make the oil in the oil pocket, be provided with oil distribution casing 7 in the position of oil pocket contact cylinder body.
Preferably, cylinder cap is connected to cylinder body by nut 9 and flush type double-screw bolt 8.Perhaps, cylinder cap by nut and penetration type Stud connection to cylinder body.
Preferably, oil distribution casing is inner sunken face near the surface of diaphragm, and cylinder cap is inner sunken face near the surface of diaphragm.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment all still belong to the protection domain of technical solutions of the utility model.
