LNG增压输送模块性能试验及其研究

以天然气为燃料的环保发动机,如天然气的气体机,以及天然气和柴油的双燃料机等,近年来得到迅速发展。作为这些发动机燃料供给系统中的重要一环,液化天然气(LNG)增压输送模块是影响发动机运行性能的关键设备。文章针对LNG增压输送模块的性能试验进行了相关研究,阐述了试验方法、试验场地、试验设备、试验数据分析和试验注意事项等。整个试验方法在真实反映模块和潜液泵实际工作性能的同时,或可使生产厂家以及用户快速、经济地进行该LNG增压输送模块的性能测试。

Performance Test and Research on LNG Pressurized Transport Module

Environment-friendly engines fueled by natural gas,such as gas engines powered by natural gas and dual-fuel engines powered by natural gas and diesel,have developed rapidly in recent years.As an important part of the fuel supply system of these engines,the LNG pressurized transport module is a key equipment that affects the engine performance.In the paper,the performance test of LNG pressurized transport module is studied,including the test method,test site,test equipment,test data analysis and test matters needing attention.The whole test method can not only reflect the actual working performance of the reflecting module and submerged pump,but also enable manufacturers and users to quickly and economically test the performance of the LNG pressurized transport module.
