在天然气长输管道、站场放空、紧急切断等场景中,气液联动执行机构是保障管线安全运行的核心设备之一。其驱动方式的核心逻辑是“气为动力源,液为传动介质”:
这种设计不依赖外部电源,特别适合野外无市电、环境恶劣的长输管道站场;液压油缸的引入也让阀门开关过程更加平稳可控,避免了纯气动执行器在大扭矩场合下冲击大、精度低的问题。
相比传统活塞式(拨叉式)结构,叶片式气液联动执行机构优势可量化:
产品背后的制造与技术根基
江苏兰格特可为PNG长输管网、CNG高压场站、LNG低温气化站等燃气工况提供一站式扭矩匹配定制服务。
气液联动执行机构的结构选型与厂商的工程落地能力,直接关系到管网的本质安全与长期运维成本。叶片式结构凭借更短的传动链、恒定的扭矩输出和更高的机械效率,正成为行业内值得关注的选型方向。
如果您正在为天然气、石化管网项目寻找扭矩匹配精准、交付稳定可靠的执行机构合作伙伴,欢迎随时联系江苏兰格特——我们期待与您携手,为您的项目提供更优的扭矩解决方案。
