摘要
针对在LNG接收站中螺杆式空压机组出现多种不同复杂因素导致的温度异常情况,为了提高空压机组的运行可靠性,有必要对其温度参数进行深入分析。对螺杆式空压机的基本构造及排气原理进行了介绍,系统性地分析了排气温度异常增高、天气炎热排气温度增高、天气寒冷排气温度低于联锁值3种温度异常现象的影响,并通过制定针对性的故障处理及维护措施以解决空压机出现的各种温度异常情况。
In many LNG receiving terminals, screw air compressors often appear abnormal temperature due to various complexities. So, it is necessary to implement a further analysis on temperature parameters. In this paper, the basic structure and exhaust theory of air compressors are illustrated; and then, the factors affecting three abnormalities are analyzed, containing abnormal increase of exhaust temperature, exhaust temperature increase due to hot weather, and exhaust temperature less than interlock value owing to cold weather; in addition, some improvement and maintenance measures are made to solve temperature abnormality.
