The invention discloses an impact-resistant high-pressure rubber hose. The impact-resistant high-pressure rubber hose comprises an inner rubber layer, a middle rubber layer, an enhancement layer and an outer rubber layer which are sequentially connected; a filling layer is further arranged between the outer rubber layer and the enhancement layer, and fillers of the filling layer are yellow sand or a mixture of yellow sand and calcium carbonate or sponges; the enhancement layer is a multi-layer steel wire weaving or winding layer; and a plurality of protrusions are further arranged outside the outer rubber layer and are irregularly arranged on the outer rubber layer. According to the impact-resistant high-pressure rubber hose, the position between the outer rubber layer and the enhancement layer is filled with the yellow sand or the mixture of the yellow sand and the calcium carbonate or the sponges, when it is hot, the temperature in the high-pressure rubber hose can drop, the effect of buffering the high-pressure rubber hose is achieved, when the high-pressure rubber hose is collided or frequently collided, the collision force can be buffered, the situation that outside collision force enables the high-pressure rubber hose to directly burst or crack is avoided, the anti-collision performance of the high-pressure rubber hose is strengthened, the better anti-collision effect can be achieved, the quality of the high-pressure rubber hose is effectively improved, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to high-pressure rubber pipe technical field, particularly relate to a kind of shock-resistant high-pressure rubber pipe.
Background technique
High-pressure rubber pipe is mainly used in carrying in mine hydraulic support, oil field development, engineering construction, lifting transport, metallurgical forging and stamping, mining equiment, boats and ships, injection machine, farm machinery, various lathe and each industrial department mechanization, automatic liquid pressing system the pipeline of the petroleum base (as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricant oil) with certain pressure and temperature and water fluid (as emulsified liquid, oil-water emulsion, water) etc. and liquid transmission.
High-pressure rubber pipe in use, although under the guaranteed prerequisite of quality, if improper use, also can shorten widely sebific duct ground working life.In real work, most of high-pressure rubber pipe ground damages all because improper use causes.Main cause has: (1) is by frequent, violent compression shock.There is explosion in high-pressure rubber pipe, be not generally because of bear static pressure too greatly caused by, but relevant with number of times with the severe degree of compression shock.When operation, can there is the unexpected rising of oil pressure or the situation of reduction in engineering machinery, thus form repeatedly to oil pipe compression shock frequently in oil pipe, cause that the oil sealing in each portion damages aggravation, bubbling and breaking and the loose leaky phenomenon of pipe joint appears in sebific duct.Therefore, when operating, pulling of valve rod can not be too quickly, must be mild.(2) serviceability temperature of fluid is too high.During engineer machinery operation, hydraulic system makes fluid generate heat because of power loss, adds the impact (especially in summer) of outside air temperature, oil temperature can be made sharply to raise.Fluid serviceability temperature is higher, and rubber is more aging, and elasticity is deteriorated, and intensity and sealability decline, and sebific duct will burst very soon.Therefore, in operation, when hydraulic system occurs that temperature rise is too high, too fast, should ascertain the reason in time, be got rid of; Operation in summer, when particularly working continuously, should take necessary cooling measure.(3) sebific duct select, install unreasonable.When changing high-pressure rubber pipe, the length of selected sebific duct, the steel wire number of plies, joint geometry and size are all wanted rationally, and should reduce sebific duct degree of crook as far as possible; When tightening Female connector fittings, do not make sebific duct produce distortion, excessive bending and distortion can reduce the working life of sebific duct greatly; Should protective measures be taked to the position that friction easily occurs for some, burst because of wearing and tearing to prevent sebific duct.Above-mentioned fault, makes high-pressure rubber pipe when routine use, and the comparatively easy working environment because of high/low temperature uses and causes aging, and the life-span is lower, changes comparatively frequent, affects the development progress of mine, oil field, engineering construction etc., reduce working efficiency.
