爆破试验台：常用的胶管检验方法

常用的胶管检验方法Hose test methods in common use许多国家的橡胶通用试验标准都规定了一套检验各类橡胶管使用可靠性的方法，另在一些产品标准中也有不少专用试验方法逐渐被广泛采用。这些方法有：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. 胶管尺寸测量内径外径增强层外径壁厚同心度内外层胶厚组合件内径，新的国标和ISO增加了长度和测量点标志，规定了无管接头和有各种管接头的胶管长度的测量方法。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. 液压试验2. The hydraulic pressure test—验证压力试验：检验软管和组合件在验证压力下持续30s-60s是否产生泄漏，变形和破坏。- verify the pressure test: test under validation pressure hose and assembly for 30 s to 60 s produce leaks, deformation and failure.—承压变形试验：在规定的压力（工作压力验证压力或其他低于验证压力的压力）下保持1分钟，测量胶管的长度和外径变化及扭转角度和弯曲。- 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.—在爆破试验台http://www.xinmingte.com/中进行爆破压力试验：测定在规定的升压速度下，胶管发生爆破时的压力。- in blasting test bench blasting pressure test: determination under prescribed booster speed, pressure hose blasting occurs.—泄漏试验：在最小爆破压力的70%的静压下保存5min，反复一次，检查是否泄漏或破坏。由于试验往往用水，与实际使用液体的粘度不同，常温下测定的爆破压力和泄漏压力可能稍低。- 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.(通常胶管设计的工作压力就是可供使用的最大压力，为了验证胶管牢固性进行的非破坏性试验的压力叫验证压力，通常为工作压力的1.5—2倍，胶管产生爆破时的压力称爆破压力，为工作压力的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.)
