前进化工厂年产三十万吨乙烯装置中的裂解气压缩机(设计位号为GB—201)、乙烯压缩机(位号为GB—601)和丙烯压缩机(位号为GB—501),是由汽轮机直接驱动的离心式压缩机(简称“三机”)。是生产过程中的关键设备。因此在一年一度的三机大检修中,联轴器的对中找正工作就成为十分重要的环节。通过联轴器的对中找正,使机组的各轴中心达到对中同轴的要求,从而消除轴在联轴器处不应有的机械成力,使机组运转时各轴能保持合理的对中状态,以保证长期平稳正常地连续运转。实践证明联轴
The precursor chemical plant produces cracked gas compressor (GB-201), ethylene compressor (GB-601) and propylene compressor (GB-501) with an annual capacity of 300,000 tons of ethylene unit. , Is a centrifugal compressor directly driven by steam turbine (referred to as “three machines”). Is the key equipment in the production process. Therefore, in the annual maintenance of the three aircraft, the coupling alignment work to become a very important part. Through the alignment of the coupling, the center of each shaft of the unit achieves the requirements of the coaxial center, thus eliminating the unforgettable mechanical force of the shaft at the coupling, which makes the shafts maintain a reasonable In the state, in order to ensure long-term stable and normal continuous operation. Practice proved that coupling
