摘要:

盘车装置是裂解气压缩机组的安全保护装置。某乙烯装置裂解气压缩机组汽轮机在单试期间,盘车装置运行正常,当汽轮机与压缩机通过联轴器组合后进行盘车时,盘车装置出现反复抖动,压缩机组转子不能正常旋转,盘车装置无法满足压缩机组盘车要求。文中针对乙烯装置中裂解气压缩机组盘车装置在启动过程存在的问题进行了深入分析,通过降低转速、提高扭矩的方法,确保压缩机组盘车装置正常运转。

Abstract:

Turning gear is a safety protection device for cracking gas compressor unit. During the single test of the steam turbine of a cracking gas compressor unit of an ethylene plant, the turning gear was operated normally. When the compressor unit was turned up after the combination of steam turbine and compressor through the coupling, the turning gear shook back and forth, and the compressor rotor could not rotate normally. The turning gear could not meet the turning requirements of the compressor unit. In this paper, the problems in the starting process of the turning gear of cracking gas compressor unit in ethylene plant are analyzed in depth, and a corresponding solution is put forward. By lowering the rotating speed and increasing the starting torque, the normal operation of the turning gear of compressor unit can be ensured.
