The compound spring of metal rubber adopts the metallic disc little gasbag of form and becomes integrative elastic element with the rubber complex, has advantage in an organic whole of metal spring and rubber concurrently, overcomes shortcoming between them, and performance is stable, can hold loading lotus and great deflection, have advantages such as vibration isolation the noise reduction effect is good, weak point of steady resonance region time of work simultaneously.
Description
Technical field
The utility model belongs to technical field of hydraulic pressure, particularly relate to a kind of metal rubber composite spring separated accumulator, the utility model belongs to technical field of hydraulic pressure, particularly relate to a kind of metal rubber composite spring separated accumulator, for having higher temperature, limited space system and the occasion being not easy to safeguard.Its structure is unique, easy to maintenance, has excellent damping.Stainless steel spring humidity, corrosion-resistant long service life can be replaced.Do not produce spark with metal bump, be suitable for inflammable, explosive environments work.There is the characteristic working curve of similar pneumatic spring, but without gas leakage.
Background technique
Accumulator is a kind of energy savings device in hydropneumatic system, it is in due course the energy conversion in system is that compression energy or potential energy store, when system needs, again compression energy or potential energy changed into the energy such as hydraulic pressure or air pressure and discharge, again supply system is mended, when system instantaneous pressure increases, it can absorb this part energy, ensures that whole system pressure is normal.Accumulator has two kinds of purposes: the flow that load needs when low-speed motion is less than oil hydraulic pump flow, and the unnecessary flow of oil hydraulic pump stores up into accumulator, and when loading demands flow is greater than oil hydraulic pump flow, liquid is released from accumulator, with the deficiency of fluid infusion press pump flow; When shutdown but still when need maintain certain pressure, can stop solution press pump and by the leakage of accumulator bucking-out system, with the pressure of keeping system.Accumulator also can be used to the hydraulic shock pressure produced in the pressure pulsation of absorption liquid press pump or absorption system.Pressure in accumulator can produce with pressurized gas, weight or spring, and correspondingly accumulator is divided into gas type, heavy hammer type and spring.Existing spring loaded accumulator weight is heavy, and volume is large, and noise is large, and amplitude is unstable, needs piston to carry out seal isolation, once seal failure, just can not work.
Model utility content
The utility model provides a kind of metal rubber composite spring formula accumulator, to solve the problem proposed in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of metal rubber composite spring separated accumulator, for having higher temperature, limited space system and the occasion being not easy to safeguard, it is characterized in that: comprise cylindrical shell, gas end end cap, oil end end cap, blind plugging, metal rubber composite spring and guide piston, described cylindrical shell and the gas end end cap being positioned at its two ends, oil end end cap coordinates composition outer casing container, gas end end cap is provided with blind plugging, metal rubber composite spring and guide piston is provided with in described cylindrical shell, described metal rubber composite spring is positioned between the gentle end end cap of described piston.
Some ballonets arranged in parallel are provided with in described metal rubber composite spring.
Described guide piston is provided with wear ring.
Described gas end end cap, be respectively arranged with O shape and enclose and F4 ring washer between oil end end cap and described cylindrical shell.
Described housing and described gas end end cap, oil hold end cap to be connected by the mode of flange, screw thread or welding.
Metal rubber composite spring be with airtight round metal plate-like air bag with rubber combined become a columniform object, described ballonet stainless steel material manufacture, internal inflatable, also can not inflate.It is interior together with rubber combined that ballonet is rotated in rubber.
The beneficial effects of the utility model are:
1. the technical program is by metal rubber composite spring, and accumulator has the feature of simple, the safe and reliable life-span length of structure, and eliminate the shortcoming of the accumulator mentioned in background, maintenance is very little.The isolated component of accumulator adopts metal-rubber to make complex spring, has the advantage of both rubber and spring concurrently, has the elasticity required by accumulator.Its structure is unique, easy to maintenance, has excellent damping.Stainless steel spring humidity, corrosion-resistant long service life can be replaced.Do not produce spark with metal bump, be suitable for inflammable, explosive environments work.There is the characteristic working curve of similar pneumatic spring, but without gas leakage.
2. accumulator can in larger temperature range work.
3. housing and metal rubber composite spring adopt stainless steel, and antiseptic property is good, and the difference according to medium can select corresponding material, to ensure most effectively and the compatibility of medium, can be used in the system of high corrosion.The structure of accumulator, elastic element adopts metal rubber composite spring, and metal spring can be various elastic element, can be made into various suitable shape.
4. metal rubber composite spring is connected with guiding element, effectively can keep metal rubber composite spring, ensures the life-span of product.
5. because ballonet can make various structures and size, the characteristic of accumulator can be changed with job requirement, air bag can not inflate work simultaneously.As inflation, its corresponding speed is also accelerated thereupon.
6. metal rubber composite spring element can bear multidirectional pressure, and direct and fluid contact, completed the function of accumulator, therefore maintenance is few by controlled Volume Changes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure: 1-blind plugging, 2-gas end end cap, 3-O shape is enclosed, 4-F4 ring washer, 5-cylindrical shell, 6-compounded rubber spring, 7-guide piston, 8-wear ring, 9-ballonet, 10-oil end end cap
Above is a kind of assembling mode, also can adopt the method for flange or welding (no longer describing in detail).
Cylindrical shell 5 holds end cap 10 to coordinate composition outer casing container with gas end end cap 2 and oil.Gas end end cap 2,5 be respectively arranged with O shape and enclose 3 and F4 ring washer 4 between oil end end cap 10 and cylindrical shell.Gas end end cap 2 has been opened a hole, for installing blind plugging 1, blind plugging 1 is for accumulator exhaust use, and the perforate of oil end end cap 10 is used for being connected with the working line of system.Multiple ballonets 9 in metal rubber composite spring 6 arrange on request, be combined with each other and form the elastic element of accumulator together with rubber.The gas end end cap 2 of complex spring 6 contacts.Cylindrical shell 5 inner diameter is greater than the external diameter of wear ring 6, and the external diameter of wear ring 6 is greater than the external diameter of piston 7.The internal thread of cylindrical shell 5 and the outside thread of end cap 2,10 match.Piston 7 external diameter is greater than the external diameter of metal rubber composite spring 6.
Metal rubber composite spring under pressure in ballonet gas and rubber all compressed, whole complex spring smaller volume, store fluid in accumulator.When the pressure drop of system, ballonet and rubber all start to expand, the fluid expulsion of accumulator.Different structures and size, and selected material is different, can obtain different characteristic curves.Metal rubber composite spring be connected with guide piston, guide piston is for limiting complex spring and playing the guiding role.
Utilize technological scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technological scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
