爆破試驗(yàn)臺(tái)：常用的膠管檢驗(yàn)方法

常用的膠管檢驗(yàn)方法Hose test methods in common use許多國家的橡膠通用試驗(yàn)標(biāo)準(zhǔn)都規(guī)定了一套檢驗(yàn)各類橡膠管使用可靠性的方法，另在一些產(chǎn)品標(biāo)準(zhǔn)中也有不少專用試驗(yàn)方法逐漸被廣泛采用。這些方法有：Rubber universal test standard in many countries have stipulated a series of inspection of all kinds of rubber and the reliability of the method is used, the other in some product standards there are many special test method is widely used gradually. These methods are:1. 膠管尺寸測量內(nèi)徑外徑增強(qiáng)層外徑壁厚同心度內(nèi)外層膠厚組合件內(nèi)徑，新的國標(biāo)和ISO增加了長度和測量點(diǎn)標(biāo)志，規(guī)定了無管接頭和有各種管接頭的膠管長度的測量方法。1. The hose size measuring inside diameter enhancement layer outside wall thickness layer thick glue assembly concentricity inside and outside diameter, the new national standard and ISO increased the length and the measurement point mark, no pipe joint and have all kinds of pipe joint hose length measurement method.2. 液壓試驗(yàn)2. The hydraulic pressure test—驗(yàn)證壓力試驗(yàn)：檢驗(yàn)軟管和組合件在驗(yàn)證壓力下持續(xù)30s-60s是否產(chǎn)生泄漏，變形和破壞。- verify the pressure test: test under validation pressure hose and assembly for 30 s to 60 s produce leaks, deformation and failure.—承壓變形試驗(yàn)：在規(guī)定的壓力（工作壓力驗(yàn)證壓力或其他低于驗(yàn)證壓力的壓力）下保持1分鐘，測量膠管的長度和外徑變化及扭轉(zhuǎn)角度和彎曲。- pressure deformation test: the pressure of regulation (work pressure test pressure or other below validation) keep 1 minute, measuring the changes of the length and diameter of hose and torsion Angle and bending.—在爆破試驗(yàn)臺(tái)http://www.jujiaso.cn/中進(jìn)行爆破壓力試驗(yàn)：測定在規(guī)定的升壓速度下，膠管發(fā)生爆破時(shí)的壓力。- in blasting test bench blasting pressure test: determination under prescribed booster speed, pressure hose blasting occurs.—泄漏試驗(yàn)：在最小爆破壓力的70%的靜壓下保存5min，反復(fù)一次，檢查是否泄漏或破壞。由于試驗(yàn)往往用水，與實(shí)際使用液體的粘度不同，常溫下測定的爆破壓力和泄漏壓力可能稍低。- leakage test: 70% of the minimum burst pressure under the static pressure of 5 min, over and over again once, check whether leakage or damage. Because of its water, often differs from the actual use of the viscosity of the liquid, burst pressure of temperature measurement and leak pressure may be slightly lower.(通常膠管設(shè)計(jì)的工作壓力就是可供使用的最大壓力，為了驗(yàn)證膠管牢固性進(jìn)行的非破壞性試驗(yàn)的壓力叫驗(yàn)證壓力，通常為工作壓力的1.5—2倍，膠管產(chǎn)生爆破時(shí)的壓力稱爆破壓力，為工作壓力的3—10倍。)(usually the hose design maximum pressure, working pressure is available to test for a hose firmly non-destructive test pressure is called validation, usually 1.5-2 times for work pressure, the pressure of the blasting according to blasting pressure hose, 3-10 times of working pressure.)
