空压机高压缸振动故障原因分析及处理

摘要

For the air compressor high pressure cylinder(101-JHP)for US-type 300,000 tons per year ammonia plant, as the increas-ing of speed, load and operating time, the value of shaft vibration at suction end gradually rising after a overhaul. Operating nearly a year later, the vibration value of measuring point of its vertical direction (1V7XHPS) had reached 62 μm before the overhaul again. The paper analyzed the vibration fault and intruded the final treatments.%30万t/a合成氨装置空气压缩机高压缸(101-JHP)在某次大修后运行时,随着转速和负荷的增加以及运行时间的增长,入口端轴振动值逐渐上涨,运行近一年后,再次大修前其垂直方向(1V7XHPS)测点振值已达62μm,就该振动故障原因进行分析,并介绍最终的处理办法.
