1玻璃球喷头无损检测技术1.1概述成都微巨科技有限责任公司(原成都玻璃研究所)采用的玻璃球喷头无损检测技术(见图1)是利用玻璃应力检测仪目视比较测量玻璃球在受力(装配压力)状态下应变图案的异同。该项技术需用设备有:玻璃应力检测仪、压力检测仪和专用压力检测装置。1.2基本原理玻璃球喷头无损检测技术基本原理是:①常温下的玻璃在持续外力作用下会产生应力,作用力越大(至玻璃裂碎前),应力越大。玻璃体应力的大小,可
1 glass ball nozzle nondestructive testing technology 1.1 Overview Chengdu micro giant technology limited liability company (formerly Chengdu Glass Research Institute) used glass ball nozzle nondestructive testing technology (see Figure 1) is the use of glass stress detector visual comparison of glass ball in the subject Similarities and Differences of Strain Patterns in Force (Assembly Pressure). The technology required equipment are: glass stress detector, pressure detector and special pressure testing device. 1.2 Basic principles Glass ball nozzle nondestructive testing technology basic principles are: ① room temperature glass under continuous external force will produce stress, the greater the force (to the glass before the crack), the greater the stress. The size of the vitreous stress can be
