Background technique is current, along with hydraulic system is to high speed and high pressure future development, hydraulic system vibration problem is day by day serious, and the rate of fault brought and failure rate also significantly promote, and it has become and limits one of its Main Bottleneck to high speed and high pressure future development.Axial piston pump is the heart of hydraulic system, pump discharge flow pulsation is one of main source of hydraulic system vibration, and propagated by pipeline, cause down-stream system judder, absorbing pumping hole flow pulsation is the effectively mode of one reducing hydraulic system vibration, but, absorb the vibration control effect of flow pulsation, than after flow pulsation excites solid liquid interation, go to control vibration more more direct effectively, therefore, pumping hole pipeline plays vital effect in the pulsation reducing pump.Such as, the effective measures that damping larynx is the weakening of most of high-pressure hydraulic main pump outlet are installed, this mode reduces the harm that pumping hole flow pulsation brings to a certain extent, with regard to structure, damping larynx is the hydralic hose that a kind of inside is integrated with multilayer steel wire, and the elastic performance that rubber material and steel wire have can absorb vibrational energy better.In addition, hydraulic system in the course of the work, be subject to extraneous load disturbance, forced vibration can be formed in the actuator such as oil hydraulic cylinder, oil hydraulic motor, and then judder is formed in pipe-line system, be the common measures taken reducing this part vibration at actuator's high-pressure mouth installation hydralic hose and pipe attenuator.Because the material of existing hydralic hose and structure are " rigid material and elastic material intersect mixed weaving ", main dependence elastic material vibration damping, be subject to structural strength restriction, the rigidity of elastic material is larger, Absorbing Fluctuation and vibration limited in one's ability, pipe attenuator generally wraps on steel pipe or high strength sebific duct outer surface, its material and structure are " rigid material is interior; elastic material outside ", the work essence that this vibration absorber absorbs is vibrated by rubber material absorbing structure, instead of directly absorb flow pulsation, vibration control limited efficiency.
At present, the braided steel wire flexible pipe being widely used in hydraulic system is made up of inner glue layer, mesoglea, one to four layer of braided steel wire enhancement layer and outer glue-line, and steel wire winding layer by layer number is more, and caliber is less, and the compression resistance of sebific duct is higher.Existing design, such as: Chinese invention patent CN1786541A discloses a kind of pressure resisting Silicon rubber hose, the material of main part of inner glue layer and outer glue-line is all silicone rubber, manufacturing process is improved by prevulcanization process, obtain the rubber hose that resistance to pressure is good, but inner diameter is little, and is suitable only for and is applied in food, pharmaceutical industry.Chinese patent CN1995791A discloses a kind of silastic hose, and this flexible pipe adopts stainless steel coil to reinforce, and hose strength is strengthened, but therefore the elasticity of flexible pipe is inhibited, and Absorbing Fluctuation is poor.US granted patent US4285534 discloses a kind of flexible pipe of Absorbing Fluctuation, these flexible pipe two ends arrange throttling material, and are provided with throttling arrangement in pipe, thus flow pulsation is inhibited, but fluid, by causing energy loss during restriction, affects efficiency.
Summary of the invention the object of the present invention is to provide a kind of copy cheetah heart to export that blood vessel structure makes is not only high pressure resistant but also can absorb the bionic type hydraulic tube of flow pulsation.
Concrete technological scheme of the present invention is as follows:
A kind of bionic type hydraulic tube, this hydraulic tube is the pipe of four layers, and it is radially followed successively by internal layer, middle level A, middle level B and skin from inside to outside, and adjacent two layers is mutually bonding; Wherein internal layer is nitrile butadiene rubber pipe; Described middle level A is the braiding webmaster become with weft knit by warp, and it is centered around and coexists in a plane with the warp on central axis parallel and center line; Described middle level B is steel wire network pipe; Described skin is rubber pipe.The braiding webmaster of described middle level A, it takes satin weave mode to make by warp and parallel, and its middle longitude is polyester thread, and its parallel is polyurethane line; The steel wire network pipe of described middle level B, its steel wire is stainless steel steel wire or aluminum alloy steel wire or titanium alloy steel wire; The steel wire network pipe of above-mentioned middle level B can be 1 layer of steel wire, also can be the 1-4 layer steel wire be woven into from inside to outside.The skin be wrapped in outside the B steel wire network pipe of middle level is preventing rubber layer; Or outside the A of middle level, be provided with the common rigidity hydraulic pipe line replacing middle level B and preventing rubber layer, as Stainless Steel Alloy, aluminum alloy, titanium alloy pipeline.In addition, each layer of the present invention adopts has that certain viscoelastic glue is bonding to be formed, and makes each layer become as a whole, has better overall performance.
Hydraulic tube body of the present invention can have the external diameter of 8mm to 70mm and the thickness of 2mm to 10mm.Selecting of flexible pipe can be selected by the selecting method of general flexible pipe.
Cheetah can only need 4 second time in moment from the static state to 70 kilometers per hour of speed per hour, and in this process, cheetah heart outlet blood vessel subjects the blood flow pressure pulsation of high-frequency and high-voltage.Why cheetah heart outlet blood vessel can bear the blood flow pressure pulsation of high-frequency and high-voltage, is because cheetah heart outlet blood vessel is made up of inner membrance, middle film, adventitia three layers.Inner membrance is made up of endothelium, subendothelial layer and internal dielectric membrane.Subendothelial layer is thicker, wherein containing collagenous fibres, elastomeric fiber and a small amount of smooth muscle, and the active receiving extrinsic innervation of each cell or by the impact of hormone being diffused into each cell.Internal dielectric membrane is mutually bonding with the elastic membrane of middle film.Middle film has 40 ~ 70 layers of elastic membrane.Each layer elastic membrane is connected by elastomeric fiber, has annular smooth muscle between elastic membrane, a small amount of collagenous fibres and elastomeric fiber etc.Adventitia is relatively thin, is made up of connective tissue, and major part is collagenous fibres, also has a small amount of elastomeric fiber.Research finds, just because of this structure of blood vessel, cheetah is when strenuous exercise, although blood pressure raises suddenly in body, pulsation amplitude and frequency increase rapidly, but due to the slickness of endangium and the good viscoelasticity in middle level, make in blood flow process, on-way resistance is little, and Absorbing Fluctuation ability is strong, simultaneously when blood vessel dilatation, blood pressure raise rapidly, collagenous fibres produce very big tension force line artery and expand further, and blood vessel can not be able to be broken when pressure raises suddenly.So, the bionical hydraulic tube internal layer of the present invention copying cheetah heart to export blood vessel structure making selects nitrile butadiene rubber (NBR) material being easy to be processed into smooth surface, this layer of inwall can be made to have higher smoothness, on-way resistance when hydraulic oil flows through can be reduced, reduce turbulent flow to produce simultaneously, reduce the possibility that turbulent flow excited vibrational produces; The elasticity Absorbing Fluctuation layer that middle level A is become with weft knit by warp, it can flow pulsation to a great extent in suction line, warp selects polyester material, the advantage of polyester material is that intensity is higher, resilience is comparatively strong, and can resist the distortion of pipeline inner wall in a big way, parallel selects polyurethane material, the advantage of polyurethane is that elasticity is strong, effectively can absorb flow pulsation, above-mentioned graticule is woven together, and can ensure that this middle level A has enough resiliences and high-selenium corn pulsation performance; Middle level B and skin select steel wire and rubber material respectively, and steel wire is wrapped up by rubber, similar to conventional hydraulic sebific duct, make rubber hose have enough intensity, and steel wire can not expose in atmosphere, avoid corrosion.
