Abstract
A hydraulic energy accumulator comprises a shell body, an air plug and an oil plug, wherein the air plug and the oil plug are arranged at two ends of the shell body, the air plug is provided with an air valve, the oil plug is provided with an oil outlet, an inner cavity of the shell body is provided with a sliding piston, an inflation cavity is formed between the sliding piston and the air plug, an oil filling cavity is formed between the sliding piston and the oil plug, the sliding piston is provided with a through hole communicating the inflation cavity with the oil filling cavity, and an elastic diaphragm is arranged on the sliding piston close to the oil plug end. The hydraulic energy accumulator is simple in structure, can effectively solve the problem that different types of traditional hydraulic energy accumulators are not compatible in performance, can meet use requirements of system pulse absorbing, high work pressure, large capacity, large discharge capacity (large instantaneous power) and installation at any position, and is good in equipment compatibility.
Description
Technical field
The invention belongs to the hydraulic equipment technical field, particularly a kind of hydraulic accumulator.
Background technique
At present, conventional hydraulic accumulator A wide selection of colours and designs, but dissimilar hydraulic accumulator respectively has its deficiency, and for example: diaphragm accumulator can be pulsed by absorption system, but its working pressure is low, capacity is little; Bladder type hydropneumatic accumulator can absorption system pulsation, working pressure is high, capacity is large, but discharge capacity little (instantaneous power is little), and must vertical installing and using; The working pressure of sliding piston formula accumulator is high, capacity is large, discharge capacity large (instantaneous power is large), also can install and use any position, but can not the absorption system pulsation.Therefore, there is the incompatible defective of dissimilar performance in the conventional hydraulic accumulator, can not satisfy simultaneously absorption system pulsation, working pressure is high, capacity is large, discharge capacity large (instantaneous power is large) and usage requirement that can the installation of any position.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, compatible good hydraulic accumulator of performance.
For achieving the above object, technological scheme of the present invention is: a kind of hydraulic accumulator, the gas that comprises housing and housing two ends installation is stifled stifled with oil, gas blocks and is provided with suction valve, and oil blocks and is provided with oil outlet, and the housing inner chamber is provided with sliding piston, consist of inflatable chamber between sliding piston and gas are stifled, consist of oil-filled chamber between sliding piston and oil are stifled, offer the through hole that is communicated with inflatable chamber and oil-filled chamber on described sliding piston, on sliding piston, the stifled end of nearly oil is provided with elastic diaphragm.
Described sliding piston is provided with elastic diaphragm one end and is provided with interior concaved circular cambered surface, and oil blocks up the inner and is provided with interior concaved circular cambered surface.
Described through hole axially arranges.
Compared with prior art, advantage of the present invention is:
1, the gas that the present invention includes housing and housing two ends installation is stifled stifled with oil, gas blocks and is provided with suction valve, oil blocks and is provided with oil outlet, the housing inner chamber is provided with sliding piston, consist of inflatable chamber between sliding piston and gas are stifled, consist of oil-filled chamber between sliding piston and oil are stifled, offer the through hole that is communicated with inflatable chamber and oil-filled chamber on described sliding piston, on sliding piston, the stifled end of nearly oil is provided with elastic diaphragm, it is simple in structure, can effectively solve the incompatible problem of the dissimilar performance of conventional hydraulic accumulator, can satisfy simultaneously the absorption system pulsation, working pressure is high, capacity is large, discharge capacity large (instantaneous power is large) and usage requirement that can the installation of any position, equipment compatibility is good.
2, sliding piston is provided with elastic diaphragm one end and is provided with interior concaved circular cambered surface, and oil blocks up the inner and is provided with interior concaved circular cambered surface, and interior concaved circular cambered surface and interior concaved circular cambered surface can effectively be protected the elastic diaphragm ultimate deformation.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Hydraulic accumulator as shown in Figure 1, it comprises that gas stifled 2 of installing in housing 1 and housing 1 two ends and oil are stifled 3, and gas stifled 2 is provided with suction valve 5, and oil stifled 3 is provided with oil outlet 6.Housing 1 inner chamber is provided with sliding piston 4, consists of inflatable chamber 7 between sliding piston 4 and gas stifled 2, consists of oil-filled chamber 8 between sliding piston 4 and oil stifled 3.Be provided with elastic diaphragm 10 at stifled 3 ends of the nearly oil of sliding piston 4, offer the through hole 9 of the axial setting that is communicated with inflatable chamber 7 and elastic diaphragm 10 on sliding piston 4.Be provided with interior concaved circular cambered surface 11 on nearly oil-filled chamber 8 end faces of sliding piston 4, elastic diaphragm 10 is positioned at concaved circular cambered surface 11, and oil blocks up 3 the inners and is provided with interior concaved circular cambered surface 12, and interior concaved circular cambered surface 11 can effectively be protected elastic diaphragm 10 ultimate deformations with interior concaved circular cambered surface 12.
Working principle of the present invention is: sliding piston 4 is isolated into inflatable chamber 7 and oil-filled chamber 8 two-part with housing 1, and sliding piston 4 is provided with through hole 9, elastic diaphragm 10 is installed, and elastic diaphragm 10 left ends and the same pressure of inflatable chamber 7, right-hand member and oil-filled chamber 8 are with pressing; Utilize the compressive characteristics of gas, storage hydraulic energy when hydraulic system pressure raises discharges hydraulic energy, when oil-filled chamber 8 pressure change when hydraulic system pressure reduces, but this part energy that elastic diaphragm 10 absorption pressure change makes system's pulsation reduce or eliminate; When hydraulic system pressure changes little when being not enough to overcome the surface friction drag of sliding piston 4, utilize the elasticity of elastic diaphragm 10 to increase or reduce gas volume and reach storage or discharge hydraulic energy, at this moment, the sensitivity of utilizing 10 pairs of pressure of elastic diaphragm to change is eliminated the system pressure pulsation; When hydraulic system pressure changes surface friction drag greater than sliding piston 4, sliding piston 4 seesaws to increase or reduce the volume of gas, to reach the purpose of storage or release hydraulic energy, at this moment, utilize the large capacity of displacement distance bucking-out system of sliding piston 4, the pressure of large discharge capacity to change.
When the present invention uses, need the resistance to motion of test sliding piston 4, guarantee that the resistance to motion of sliding piston 4 is less than the ultimate deformation of elastic diaphragm 10.
