安全阀装在压缩机每级排气管道上,限制气体压力过分的升高的一种装置。为了避免这种装置因不经常工作而被锈蚀卡住,因此,每年都定期验证一次,但验证后常出现漏气现象,轻者放入水中试验密封性,胃气泡的数量超过说明书要求;重者在设备运行时用手触及或用肥皂水,都有风的感觉和大量气泡冒出。尤其是氢压机安全阀泄漏出的氢气与操作间空气混合,达到一定百分比的体积,就形成爆鸣气,在有静电与火星的作用下,即刻发生爆炸,很不安全。为此,我们在多年的实践运行中,作了专门的探讨与相应的治理,达到了预期的目的,现将我们的治漏办法归纳如下:
Safety valve mounted on each stage of the compressor exhaust pipe, limiting the gas pressure is too high a device. In order to avoid this device due to infrequent work was rust stuck, therefore, regularly verified once a year, but often leaks after verification, the light into the water test seal, the number of gastric bubbles in excess of manual requirements; weight When the device is in operation touch or with soapy water, have the feeling of the wind and a large number of bubbles emerge. In particular, the hydrogen compressor safety valve leaks out of the hydrogen mixed with the operating room air to reach a certain percentage of the volume, the formation of blasting gas, in the presence of static electricity and Mars, the immediate explosion, it is not safe. For this reason, we have made special discussions and corresponding governance in many years of practical operation and achieved the intended purpose. Now we can summarize our omission measures as follows:
