本文叙述了水轮发电机组检修期间,在对承压设备进行严密性耐压试验的过程中,由于检修现场缺少试压泵,且电站技术供水和消防水压力不能满足耐压试验要求,检修人员巧妙的利用电站压缩空气系统,在现场没有试压泵的情况下,巧妙的用气源压力实现了水压试验的效果,顺利完成了承压设备的严密性耐压试验,缩短了检修周期,大大节约了人力和物力。 This article describes the turbine generator overhaul, pressure equipment in the process of tight pressure test, due to the lack of test site pressure test pump, and power station water and fire water pressure can not meet the pressure test requirements, maintenance personnel Clever use of compressed air power plant system, the scene without test pump case, the clever use of air pressure to achieve the effect of hydrostatic test, the pressure equipment to complete the tightness of the pressure test, shorten the inspection cycle, greatly Save manpower and material resources.
