The compression section of traditional diaphragm type compressor is mainly added oil distribution casing by cylinder body and adds diaphragm and add cylinder cap and form, oil distribution casing and cylinder cap are sealed the curve-surface cavity formed and are divided into high-voltage oil cavity and high pressure air cavity by diaphragm, cylinder cap end face side arranges the air inlet of air cavity, venthole, cylinder body and cylinder cap to bear significantly high pressure, so the comparison done is thick and heavy, make the compressor of huge discharge, usually strengthen cylinder body, oil distribution casing, the diameter of diaphragm and cylinder cap realizes, at the container bearing same pressure, diameter is more big, thickness is also more big, complete machine is heavy, cost of manufacture and difficulty increase.
Additionally, curve-surface cavity is divided into high pressure air cavity and high-voltage oil cavity by diaphragm by existing diaphragm type compressor, the oil distribution casing of oil pocket side arranges oil guiding hole, air cavity side cylinder cap arranges air inlet/outlet, existing this structure, owing to oil gas two ends exist pressure reduction, the moment that diaphragm contact with hole when reciprocal concussion is often made to produce impulsive force, therefore in oil distribution casing oil guiding hole and the especially easy damage in diaphragm position being positioned at corresponding to the air inlet/outlet of cylinder cap.
Summary of the invention
The present invention provides a kind of superposing type huge discharge diaphragm type compressor, this superposing type huge discharge diaphragm type compressor one of solves the technical problem that and can increase discharge capacity in certain volume, thus reducing manufacture difficulty and reducing cost, two solved the technical problem that are able to avoid being positioned at oil distribution casing oil guiding hole and the problem of the damage of the diaphragm position corresponding to air inlet/outlet being positioned at cylinder cap.
In order to solve above-mentioned technical problem, the superposing type huge discharge diaphragm type compressor of the present invention, including cylinder body, it is arranged on the cylinder cap on cylinder body, from bottom to up at least provided with two groups of compression mechanisms being overlapped mutually between cylinder body and cylinder cap, often group compression mechanism all includes the oil distribution casing and gas distribution plate that are arranged in pairs, it is provided with diaphragm between every pair of oil distribution casing and gas distribution plate, oil distribution casing is provided with the oil guiding hole being positioned at oil pocket side, each oil distribution casing arranges repairing fuel feed hole and the superpressure spout hole of the oil pocket leading to oil distribution casing, slippage pump is connected on repairing fuel feed hole after in line check valve, the outlet of superpressure spout hole connects a fuel tank after an overflow valve, each group is compressed and is respectively provided with air inlet and steam vent on the gas distribution plate in mechanism.
The orlop that is positioned at arranged in described cylinder body compresses the piston below mechanism, and the power end of piston connects flywheel by toggle, and the slippage pump that the side of described flywheel is arranged is a repairing plunger displacement pump.
In each group described compression mechanism the repairing fuel feed hole of oil distribution casing parallel with one another after connect in line check valve, connect overflow valve after the superpressure spout hole outlet of each described oil distribution casing is parallel with one another.
The air inlet total breather check valve of rear connection parallel with one another on the described gas distribution plate compressed in mechanism of each group, the venthole total exhaust check valve of rear connection parallel with one another on the described gas distribution plate compressed in mechanism of each group.
High-voltage oil cavity that the oil distribution casing being arranged in pairs and gas distribution plate are divided into by described diaphragm and high pressure air cavity, the end face of described high-voltage oil cavity is provided with oil pocket shoulder hole, described oil guiding hole is the soft oil-hole plug being placed in oil pocket shoulder hole, being provided with air cavity shoulder hole on the end face of described high pressure air cavity, described air inlet and venthole are respectively placed in the soft air inlet stopple in air cavity shoulder hole and soft stopple of giving vent to anger.
It is provided with sealing ring between described oil distribution casing and gas distribution plate.
After adopting above-mentioned structure, due in cylinder body from bottom to up at least provided with two groups of compression mechanisms being overlapped mutually, oil distribution casing and gas distribution plate pressure at both sides is made to cancel out each other by the mode being overlapped mutually, so gas distribution plate and oil distribution casing all can reduce thickness, to saving material, reduce difficulty of processing and have positive role, additionally can easily change discharge capacity when not changing support by the mode of increase and decrease superposition quantity, avoid the present situation that traditional compressor different displacements support model is all different, make production cost reduce further;Additionally, due to the oil pocket shoulder hole of pyramidal structure arranged and air cavity shoulder hole and the soft oil-hole plug, soft air inlet stopple and the soft stopple of giving vent to anger that coordinate with oil pocket shoulder hole and air cavity shoulder hole respectively, thus when oil gas two ends exist pressure reduction, diaphragm can play cushioning effect when reciprocal concussion, is positioned at oil distribution casing oil guiding hole thus avoiding and is positioned at the problem generation that the diaphragm position corresponding to air inlet/outlet of gas distribution plate is damaged.
