Description
Technical field
The invention belongs to technical field of hydraulic equipment, 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, such as: diaphragm accumulator energy absorption system is pulsed, but its working pressure is low, capacity is little; Bladder type hydropneumatic accumulator energy absorption system is pulsed, working pressure is high, capacity is large, but discharge capacity little (instantaneous power is little), and must vertically install and use; 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 absorption system pulsation.Therefore, there is the incompatible defect of dissimilar performance in conventional hydraulic accumulator, can not meet absorption system pulsation simultaneously, working pressure is high, capacity is large, discharge capacity large (instantaneous power is large) and can the usage requirement of any position installation.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, the 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 comprising housing and the installation of housing two ends is stifled stifled with oil, gas blocks and is provided with suction valve, and oil blocks and is provided with oil outlet, and housing cavity is provided with sliding piston, inflatable chamber is formed between sliding piston and gas block up, form oil-filled chamber between sliding piston and oil block up, described sliding piston offers the through hole being communicated with inflatable chamber and oil-filled chamber, 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 the stifled the inner of oil is provided with interior concaved circular cambered surface.
Described through hole is axially arranged.
Compared with prior art, advantage of the present invention is:
1, the gas that the present invention includes housing and the installation of housing two ends is stifled stifled with oil, gas blocks and is provided with suction valve, oil blocks and is provided with oil outlet, housing cavity is provided with sliding piston, inflatable chamber is formed between sliding piston and gas block up, oil-filled chamber is formed between sliding piston and oil block up, described sliding piston offers the through hole being communicated with inflatable chamber and oil-filled chamber, on sliding piston, the stifled end of nearly oil is provided with elastic diaphragm, its structure is simple, effectively can solve the problem that the dissimilar performance of conventional hydraulic accumulator is incompatible, absorption system pulsation can be met simultaneously, working pressure is high, capacity is large, discharge capacity large (instantaneous power is large) and can the usage requirement of any position installation, equipment compatibility is good.
2, sliding piston is provided with elastic diaphragm one end and is provided with interior concaved circular cambered surface, and the stifled the inner of oil is provided with interior concaved circular cambered surface, and interior concaved circular cambered surface and interior concaved circular cambered surface can available protecting elastic diaphragm ultimate deformations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Hydraulic accumulator as shown in Figure 1, it comprises the gas stifled 2 of housing 1 and the installation of housing 1 two ends and oil stifled 3, and gas stifled 2 is provided with suction valve 5, and oily stifled 3 are provided with oil outlet 6.Housing 1 inner chamber is provided with sliding piston 4, forms inflatable chamber 7 between sliding piston 4 and gas stifled 2, forms 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, sliding piston 4 offer the through hole 9 being communicated with inflatable chamber 7 and arranging with the axis of elastic diaphragm 10.Nearly oil-filled chamber 8 end face of sliding piston 4 is provided with interior concaved circular cambered surface 11, and elastic diaphragm 10 is positioned at concaved circular cambered surface 11, and stifled 3 the inners of oil are provided with interior concaved circular cambered surface 12, and interior concaved circular cambered surface 11 can available protecting elastic diaphragm 10 ultimate deformation with interior concaved circular cambered surface 12.
Working principle of the present invention is: housing 1 is isolated into inflatable chamber 7 and oil-filled chamber 8 two-part by sliding piston 4, and sliding piston 4 is provided with through hole 9, is provided with elastic diaphragm 10, elastic diaphragm 10 left end and inflatable chamber 7 with pressing, right-hand member and oil-filled chamber 8 press together; Utilize the compressive characteristics of gas, store hydraulic energy when hydraulic system pressure raises, discharge hydraulic energy when hydraulic system pressure reduces, when oil-filled chamber 8 pressure changes, this part energy of elastic diaphragm 10 Absorbable rod pressure change, makes system pulse and reduces or eliminate; When hydraulic system pressure change little be not enough to the surface friction drag overcoming sliding piston 4 time, then utilize the elasticity of elastic diaphragm 10 to increase or reduce gas volume and reach storage or release hydraulic energy, now, the sensitivity of elastic diaphragm 10 pairs of pressure changes is utilized to eliminate system pressure pulsation; When hydraulic system pressure change is greater than the surface friction drag of sliding piston 4, then sliding piston 4 seesaws the volume increasing or reduce gas, to reach the object storing or discharge hydraulic energy, now, the pressure of the displacement distance bucking-out system Large Copacity of sliding piston 4, huge discharge is utilized to change.
When the present invention uses, need the resistance to motion of testing sliding piston 4, guarantee that the resistance to motion of sliding piston 4 is less than the ultimate deformation of elastic diaphragm 10.
