Description
Technical field
The present invention relates to high-pressure rubber pipe technical fields, more particularly to a kind of from cooling high-pressure rubber pipe.
Background technology
High-pressure rubber pipe is mainly used for mine hydraulic support, oil field development, engineering construction, lifting transport, metallurgical forging and stamping, mine
It is conveyed in equipment, ship, injection machine, agricultural machinery, various lathes and each industrial department mechanization, automation hydraulic system
Petroleum base with certain pressure and temperature（Such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil）And water fluid（Such as
Emulsion, oil-water emulsion, water）Deng the pipeline with liquid transmission.
When in use, inner glue layer will appear following failure to high-pressure rubber pipe：(1) hose inner glue layer is hard, and has crackle：It is main
It wants, the reason is that since plasticizer is added in rubber product, to keep hose flexible plastic.But hose overheats, and plasticizer can be made to overflow.(2)
Hose inner glue layer critical deterioration, hence it is evident that swell：Hose inner glue layer critical deterioration, hence it is evident that the reason of swelling be in hose glue material matter with
Hydraulic system oil is incompatible, and hose is gone bad by chemical action.Above-mentioned failure so that high-pressure rubber pipe in routine use,
Be relatively easy to lead to aging because the working environment of high/low temperature uses, the service life is relatively low, replace it is more frequent, influence mine, oil field,
The development progress of engineering construction etc., reduces working efficiency.
In addition, high-pressure rubber pipe ruptures, nearby braided steel wire gets rusty hose fracture cut, peels off outer glue-line inspection, finds broken
Braided steel wire gets rusty near mouthful.This is mainly due to this layers caused by by moist or corrosive substance effect, and it is strong to weaken hose
Degree, causes to rupture when high pressure.(2) hose enhancement layer does not get rusty, but irregular fracture of wire phenomenon occurs in enhancement layer.Hose fracture, stripping
Go outer glue-line not find that enhancement layer gets rusty, but irregular fracture of wire occurs in enhancement layer length direction, the main reason is that hose by
The effect of high-frequency percussion power.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, high-pressure rubber pipe is cooled down certainly the present invention provides a kind of, its object is to
Improve high-pressure rubber pipe high and low temperature resistance and its anti-aging property, and be effectively reduced high-pressure rubber pipe inner glue layer corrosion and
Abrasion avoids the corrosion of enhancement layer steel wire and causes the lower possibility of hose strength, to improve the service life of high-pressure rubber pipe, into
And improve its performance.
The technical solution adopted in the present invention is：A kind of certainly cooling high-pressure rubber pipe, including sequentially connected inner glue layer, middle glue
Layer, enhancement layer and outer glue-line, enhancement layer are filled layer, and the interior filler of filled layer is the mixture of yellow ground and calcium carbonate.This
The steel wire reinforcement layer of the winding of multilayer in the prior art alternating or braiding is changed to object by invention from cooling high-pressure rubber pipe
Expect filled layer, and the mixture of yellow ground and calcium carbonate is added as filler in enhancement layer.When in high-pressure rubber pipe in high temperature ring
In use, the yellow ground in filler and calcium carbonate, can absorb the temperature of high-pressure rubber pipe release, and slowly first outer glue-line in border
Release continues the heat that release is stored in filler, plays the work of buffering high temperature heat after high-pressure rubber pipe is stopped using
With directly being discharged by inner glue layer and outer glue-line so as to avoid the heat at high-pressure rubber pipe release, alleviate the internal glue of high temperature
The thermal damage of layer and outer glue-line, extends the service life of high-pressure rubber pipe；When high-pressure rubber pipe works at low temperature, due to carbonic acid
The performance with hygroscopicity and Exotherm of calcium, yellow ground have heat-insulating property, place the frostbite of inner glue layer and outer glue-line, in turn
Improve the resistance to low temperature of high-pressure rubber pipe.
Preferably, the fineness modulus range of the yellow ground of filler is between 3.7-1.6, and the packing ratio of calcium carbonate and yellow ground
Example is 1:8 to 1:20, it is preferable from cooling and storage temperature performance to ensure that high-pressure rubber pipe has.
Preferably, the outer glue-line of high-pressure rubber pipe is silicone sealant, and several uniform cloth of circle are provided on inner glue layer inner wall
The cylindrical protrusion set either each circle cylindrical protrusion of hemispherical protrusion or the hemispherical protrusion of each circle by several cylinders
Either several hemispherical protrusions are equably arranged in each two cylindrical protrusion or spherical on the inner wall of inner glue layer to shape protrusion
Gap between protrusion is not more than each cylindrical protrusion or the radius of each bulbous protrusion；Each cylindrical protrusion
Or the height of hemispherical protrusion must not exceed the half of outer glue-line thickness.Cylindrical protrusion or hemispherical protrusion are in high pressure
It is distributed as continuous arrangement in sebific duct or is only distributed at crooked position.Outer glue-line is SS weather proofing sealants.It ensure that cylinder
The density of shape protrusion or bulbous protrusion is larger, and then the highly pressurised liquid for inner glue layer trickling provides enough cushion effects, mitigates
The friction and corrosion of highly pressurised liquid and the inner wall of high-pressure rubber pipe inner glue layer, and then improve the service life of high-pressure rubber pipe, and
High-pressure rubber pipe is further improved and is built using the mine of high-pressure rubber pipe, oil field, engineering in use, its replacement frequency can be reduced
The development efficiency built etc..
Compared with prior art, the beneficial effects of the invention are as follows：The certainly cooling high-pressure rubber pipe of the present invention, will in the prior art
Multilayer alternately wind or the steel wire reinforcement layer of braiding, be changed to material filled layer, and yellow ground and carbon are added in enhancement layer
The mixture of sour calcium is as filler.When in high-pressure rubber pipe in the high temperature environment in use, the yellow ground in filler and calcium carbonate,
The temperature of high-pressure rubber pipe release, and slowly first outer glue-line release can be absorbed, after high-pressure rubber pipe is stopped using, continues to discharge
The heat being stored in filler plays the role of buffering high temperature heat, straight so as to avoid the heat at high-pressure rubber pipe release
Inner glue layer and outer glue-line release were connected, high temperature is alleviated to the thermal damage of inner glue layer and outer glue-line, extends high-pressure rubber pipe
Service life；When high-pressure rubber pipe works at low temperature, due to the performance with hygroscopicity and Exotherm of calcium carbonate, yellow ground
With heat-insulating property, the frostbite of inner glue layer and outer glue-line is placed, and then improves the resistance to low temperature of high-pressure rubber pipe.
The high-pressure rubber pipe of the present invention improves the high and low temperature resistance and its anti-aging property of high-pressure rubber pipe, and effectively
The corrosion and abrasion for reducing high-pressure rubber pipe inner glue layer avoid the corrosion of enhancement layer steel wire and cause the lower possibility of hose strength,
To improve the service life of high-pressure rubber pipe, and then improve its performance.
