无损检测(NDT)技术对维护矿井特大承重物的质量安全与应用发挥着不可或缺的功能。其方法有很多,如超声波测试、涡流测试、渗透测试、射线测试、磁粉测试、声发射测试等。在对煤矿重要设备核心配件进行检测时,可选择着色渗透测试法与超声波测试法,则能够真正地规避断轴、轴裂等风险,维护煤矿增强系统的安全应用。对于渗透测试法与超声波测试法来说,其优势包括:测试费用少、时间短、探测设备体积小、自重轻、现场操
Non-destructive testing (NDT) technology plays an indispensable role in maintaining the quality and safety of ultra large load-bearing products in mines. There are many ways, such as ultrasonic testing, eddy current testing, penetration testing, ray testing, magnetic particle testing, acoustic emission testing. When testing core components of important equipment in coal mines, coloration and penetration testing methods and ultrasonic testing methods can be selected to truly avoid the risks of broken shafts and shaft cracks and to maintain the safety and application of enhanced systems in coal mines. For the penetration test method and ultrasonic testing method, its advantages include: less testing costs, time is short, small detection equipment, light weight, on-site operation
