Abstract
The utility model discloses a piston type energy accumulator manufacturing technology which overcomes the existing defects of the same kinds of products whose thickness of the body case makes the whole weight of accumulator products heavier. The utility model comprises a cylindrical shell and covers at both ends of the shell, wherein the centre of one end of cover is provided with an aerated port, while the centre of the other end of cover is provided with a liquid inlet or outlet port. The internal cavity of the cylindrical shell is provided with a piston that is matched with the inner wall. The cylindrical shell is made of thin walled aluminum alloy materials and the outer surface of the shell is covered with a carbon fiber winding layer. The outside surface of the circumference of the piston is provided with a plurality of sockets which are inserted with the sealing ring. The aluminum alloy shell of the utility model just plays a role of finalizing the outline design and being taken as the skeleton of the carbon fiber winding layer and The high pressure of the liquid and gas cavities is completely supported by the carbon fiber winding layer and has advantages of high pressure resisting features, corrosion resistance and light in weight and meeting the requirements of special application fields such as aviation, war industry, vehicle transportation etc.
Description
Technical field
The utility model relates to a kind of inner piston accumulator product manufacturing technology that plays auxiliary energy-storage, noise reduction and buffering function of hydraulic system that is installed on, and especially refers to the housing manufacturing technology of piston accumulator.
Background technique
Accumulator is a kind of at the inner auxiliary device that plays accumulation of energy, noise reduction and buffering function of hydraulic system.At present, the accumulator product category is various, mainly comprises rubber capsule diaphragm type, piston type and spring or the like.The rubber capsule diaphragm accumulator has simple in structure, easily manufactured because of it and steady performance is widely used, but the gas compression of this series products restricts than the performance that is subjected to rubber capsule, the gas discharge capacity is little, and the easy temperature influence of rubber capsule and limited its application area.For this reason, the colleague technician has invented a kind of piston accumulator product, for example as far back as on September 2nd, 1992 Chinese Patent Office disclose the patent No. and be called " a kind of isolated piston accumulator of protecting against shock " product for the ZL92205555.6 name, it is applicable to the hydraulic system of various variable working condition, is suitable for the hydraulic system of short period feed flow especially.It has the accumulation of energy body, piston, and liquid-storing cavity, pressure chamber is connected with the push rod housing of seal and pressure bearing on pressure chamber top, push rod is housed in it, and Returnning spring is contained in the magnetic on push rod top and is contained in hall magnetic sensor on the push rod housing.In time unload by this sensor control power source, not only saved the energy but also reduce piston with the accumulation of energy body between bump, improve the functional reliability of accumulator, prevented the system's hydraulic shock that causes owing to piston motion inertia.But along with The development in society and economy, operating air pressure in the accumulator housing is more and more higher, bring the increase of thickness of shell thereupon, the overall weight of accumulator product is significantly improved, and it is required in the application of space flight, aviation, military project and special dimension such as vehicle-mounted to have restricted the piston accumulator product thus greatly.For this reason, people's expectation has the novel piston formula accumulator that a kind of product overall weight is light, accumulation of energy pressure is high to come out.
The model utility content
The technical problems to be solved in the utility model is to overcome that thickness of shell that existing like product exists increases and defective and deficiency that the overall weight of accumulator product is significantly improved, provide the novel piston formula accumulator product that a kind of overall weight is light, accumulation of energy pressure is high to society, it is required to satisfy its application at space flight, aviation, military project and special dimension such as vehicle-mounted.
The technological scheme that its technical problem that solves the utility model adopts is: twine and reinforce the capping that piston accumulator comprises cylindrical housings and is located at the housing two ends, one end capping center is provided with the inflation interface, the other end capping center is provided with the liquid in-out interface, described shell circular cylindrical shell intracoelomic cavity is provided with the piston that matches with its inwall, described cylindrical housings is made by the thin-wall aluminum alloy material, and external layer has wrapped the carbon fiber winding layer.
The circumferential outer surface of described piston is provided with the multiple tracks groove and is embedded with seal ring.
The utility model twines reinforces piston accumulator, substitutes traditional heavy wall alloyed steel housing with the thin-wall aluminum alloy housing, and entire product weight declines to a great extent; With respect to the integral body of product, Al-alloy casing only is to play profile typing and as the skeleton of carbon fiber winding layer, the high pressure of liquid container and air chamber then relies on the carbon fiber winding layer to support fully.Because carbon fiber itself has lightweight and corrosion resistant characteristic, produced like this piston accumulator has also just possessed high pressure resistant, corrosion-resistant and lightweight advantage, can satisfy space flight and aviation, military project, special dimension such as vehicle-mounted is used required.
Description of drawings
Fig. 1 is the utility model product structure schematic representation.
Embodiment
As shown in Figure 1, the utility model twines reinforces the piston accumulator product, comprises that cylindrical housings 4 and capping 2,6, one end cappings 2 centers of being located at housing 4 two ends are provided with inflation interface 1, and the other end capping 6 centers are provided with liquid in-out interface 7.Described cylindrical housings 4 inner chambers are provided with the piston 5 that matches with its inwall, and the circumferential outer surface of described piston 5 is provided with the multiple tracks groove and is embedded seal ring 8.For weight reduction, described cylindrical housings 4 is made by the thin-wall aluminum alloy material, and columniform outer surface has wrapped carbon fiber winding layer 3.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.During use, pressurized gas are charged into the air chamber 9 of housing 4 inner chambers between inflation interface 1 and piston 5 by inflation interface 1; Simultaneously, described liquid in-out interface 7 is connected hydraulic circuit, make hydraulic oil enter the liquid container 10 of housing 4 inner chambers between piston 5 and liquid in-out interface 7.When pressure moment of hydraulic system rises, hydraulic oil enters liquid container 10, meanwhile described piston 5 is subjected to the pressure effect of hydraulic oil to air chamber 9 one side shiftings, realizes absorbing the function of impacting, eliminating pulsation, vibration damping noise reduction, stored energy and steady pressure.Otherwise described piston 5 goes out liquid container 10 with hydraulic oil pressure and enters hydraulic circuit to liquid container 10 1 side shiftings.Compared with prior art, the utility model substitutes traditional heavy wall alloyed steel housing with the thin-wall aluminum alloy housing, and entire product weight declines to a great extent.The carbon fiber winding layer is because of having lightweight characteristic, can adopt the multi-lay winding mode to improve the withstand voltage properties of housing 4, has high pressure resistant, corrosion-resistant and lightweight advantage simultaneously, can satisfy space flight and aviation, military project, special dimension such as vehicle-mounted is used required.
