我们试制了排出压力250～350大气压的高压离心压缩机,并对其油膜密封机构进行了严格的机械振动试验。曾在轴振动75μ、压缩机内压250大气压、转数14600转/分的条件下进行了100小时的耐久性试验。此外,根据API标准617,在该转数下允许振幅为23μ,试验 We have tried out a high-pressure centrifugal compressor with a discharge pressure of 250 to 350 atmospheres and conducted rigorous mechanical vibration tests on its oil-film sealing mechanism. The durability test was carried out for 100 hours under the conditions of a shaft vibration of 75 μ, a compressor internal pressure of 250 atm and a number of revolutions of 14,600 rpm. In addition, according to API standard 617, an amplitude of 23μ is allowed at this number of revolutions and the test is carried out
