大庆油田化工有限公司的醋酸生产装置中,罗茨风机为系统提供物料煤气(含高浓度一氧化碳)。由于一氧化碳气体剧毒,对罗茨风机的密封性能有很高的要求,因此我单位采用双端面四口机械密封对其密封,机体的长期运转与杂质对机封的侵害,势必造成机械密封的磨损,为了罗茨风机能够长期安全,高稳定,高性能地运转,我单位要求对罗茨风机定期进行检修与更换机械密封的工作。经过不断的学习和实际工作中的摸索,设备维修专业掌握了罗茨风机的检修技术。介绍了罗茨风机的检修过程中的运输与拆装,几个自行研究的较为实用的工具。
Daqing Oilfield Chemical Co., Ltd. acetic acid plant, Roots blower for the system to provide material gas (including high concentrations of carbon monoxide). Due to the highly poisonous carbon monoxide gas, there is a high demand for the sealing performance of Roots blower. Therefore, our unit adopts a double-end, four-port mechanical seal to seal it. The long-term operation of the airframe and the impurity encroachment on the airframe inevitably result in the mechanical seal Wear and tear, in order to Roots blower can be long-term safety, high stability, high performance operation, my unit requires regular Roots blower maintenance and replacement of mechanical seal work. After continuous learning and exploration of the actual work, equipment maintenance professionals master the Roots blower maintenance technology. The paper introduces the transportation and disassembly of Roots blower in the overhaul process, and several practical tools for self research.
