【摘要】 某炼化公司临氢装置的机泵设备采用皮带传动方式，不满足GB 50160—2008(2018版)《石油化工企业设计防火标准》相关要求，存在安全隐患，基于安全要求必须对该类机泵设备传动方式进行改造，以确保企业生产依法合规。文章针对不同结构的转动设备，选择不同的传动方式，借助于SolidWorks软件对皮带轮进行建模，构造新的飞轮结构，同时结合生产实际需要修正了机泵设备的部分技术参数。改造后的机泵设备经过几个月的运行，结果显示：机泵振动、轴承温度、噪音满足相应规范要求；流量、扬程、电流、电压等技术性能达到使用要求，并能充分满足生产需求。上述结果表明，改造彻底清除了该类设备的安全隐患，同时还提高了机泵的运行效率，使其更加节能且安全可靠，达到了预期目的。该案例可为其他危险化学品企业同类安全隐患的治理整改提供借鉴。更多还原

【Abstract】 The compressor & pump equipment of the units in hydro-processing service of a refining and chemical company adopts the belt transmission mode,which does not meet the relevant requirements of GB 50160-2008Standard for fire prevention design of petrochemical enterprises(2018 edition) and there are safety risks.Based on the safety requirements,the transmission mode of the compressor & pump equipment must be revamped to ensure that the production of the enterprise complies with the law.In this paper,different transmission modes were selected for rotating equipment with different structures.And a new flywheel structure was constructed by modeling the pulley with the aid of Solidworks software.And some technical parameters of the compressor & pump equipment were corrected according to the actual production needs.After several months of operation of the revamped compressor & pump equipment,the results showed that the compressor & pump vibration,bearing temperature and noise met the requirements of the corresponding specifications;the techoical performance such as flow,head,current and voltage met the use requirements and could fully meet the production requirements.These results indicated that the revamp had completely eliminated the safety hazards of this type of equipment and improved the operation efficiency of the compressor & pump,making it more energy-efficient and safe and reliable,which achieved the expected purpose.This case study can provide reference for the management and rectification of similar safety hazards in other hazardous chemicals enterprises.更多还原
