我所广大革命职工在毛主席“独立自主,自力更生”的方针指引下,为国产年产30万吨合成氨厂氮氢气离心式压缩机的浮环密封技术试验而建立的高压浮环密封试验台,已于1973年底建成。经过了一段时间的调试和运转试验,取得了初步成果。 Under the guidance of Chairman Mao’s principle of “independence and self-reliance”, the vast majority of our revolutionary workers have set up high-pressure floating ring seal test rigs for the test of the floating ring seal technology of an annual output of 300,000 tons of ammonia nitrogen centrifugal compressor in an ammonia plant. Built in late 1973. After a period of commissioning and operation test, and achieved initial results.
