Abstract
A double-oil-pump oil supply system for a large diaphragm compressor comprises an oil tank, the oil tank is connected with a first-stage oil replenishing pump and a second-stage oil replenishing pump through hydraulic pipes respectively, the first-stage oil replenishing pump is connected with a first-stage air cylinder through a first-stage check valve, the first-stage air cylinder is provided with a first-stage pressure regulating valve to be connected with an oil cylinder, the second-stage oil replenishing pump is connected with a second-stage air cylinder through a second-stage check valve, the second-stage air cylinder is provided with a second-stage pressure regulating valve to be connected with the oil cylinder, and a first-stage piston and a second-stage piston are arranged in the oil cylinder. Through the adoption of the technical scheme, when the diaphragm compressor is used, the two oil pumps supply oil to the two stages of air cylinders at the same time, and the efficiency is high; meanwhile, the pressure on a diaphragm can be timely adjusted through the pressure regulating valves, and thus the service life of the compressor is prolonged.
Description
Technical field
The utility model relates to a kind of diaphragm type compressor oil supply system, particularly the two oil pump feed systems of a kind of large-scale diaphragm type compressor.
Background technique
Membrane compressor is a kind of positive displacement compressor of special construction, has compression ratio large, good airproof performance, the feature that pressurized gas is not polluted by lubricant oil and other solid impurities.Therefore be applicable to compress high-purity, rare valuable, inflammable and explosive, poisonous and harmful, there is the gases such as corrosivity and high pressure, be widely used in the fields such as medical science, chemical industry.Existing diaphragm type compressor adopts single oil pump feed, and stroke is longer, and oil refluxes slow, and the frequency of compressor is difficult to accomplish very large, and efficiency is lower.
Model utility content
Goal of the invention of the present utility model is a kind of two oil pump feed systems that can significantly increase diaphragm type compressor efficiency of design, and its concrete technological scheme is:
The two oil pump feed systems of a kind of large-scale diaphragm type compressor, comprise fuel tank, fuel tank connects one-level slippage pump and secondary slippage pump by hydraulic tube respectively, one-level slippage pump connects one-level cylinder by one-level one-way valve, one-level cylinder is provided with one-level pressure regulator valve and connects oil cylinder, secondary slippage pump connects secondary cylinder by two-stage unidirectional valve, and secondary cylinder is provided with second voltage regulation valve and connects oil cylinder, is provided with first stage piston and second piston in oil cylinder.
Adopt technique scheme, when using diaphragm type compressor, two oil pumps carry out fuel feeding to two-stage cylinder simultaneously, and efficiency is higher, and pressure regulator valve can be adjusted barrier film pressure in time simultaneously, has increased the working life of compressor.
Accompanying drawing explanation
The two oil pump feed system schematic of the large-scale diaphragm type compressor of Fig. 1.
Wherein, 1 fuel tank, 2 one-level slippage pumps, 3 secondary slippage pumps, 4 one-level one-way valves, 5 two-stage unidirectional valves, 6 one-level cylinders, 7 secondary cylinders, 8 one-level pressure regulator valves, 9 second voltage regulation valves, 10 first stage pistons, 11 second pistons.
Embodiment
The embodiment who sets forth below represents and allows those skilled in the art to put into practice necessary information of the present utility model, and illustrates and put into practice best mode of the present utility model.Once read with reference to the accompanying drawings following description, those skilled in the art just will understand design of the present utility model and will recognize the application of these designs of not illustrating especially herein.Should be appreciated that these designs and application fall into the scope of disclosure and the accompanying claims book.
With reference to the two oil pump feed systems of a kind of large-scale diaphragm type compressor shown in accompanying drawing 1, comprise fuel tank 1, fuel tank connects one-level slippage pump 2 and secondary slippage pump 3 by hydraulic tube respectively, one-level slippage pump 2 connects one-level cylinder 6 by one-level one-way valve 4, one-level cylinder 6 is provided with one-level pressure regulator valve 8 and connects oil cylinder, secondary slippage pump 3 connects secondary cylinder 7 by two-stage unidirectional valve 5, and secondary cylinder 7 is provided with second voltage regulation valve 9 and connects oil cylinder, is provided with first stage piston 10 and second piston 11 in oil cylinder.Because first stage piston 10 and second piston 11 are not synchronized with the movement, thus one-level slippage pump 2 and secondary slippage pump 3 fuel feeding respectively, can effectively reduce oil circuit and form, accelerate the operation frequency of piston.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all mode of executions.And these belong to apparent variation that spirit of the present utility model extended out or variation still among protection domain of the present utility model.
