●在冶金钢铁厂行业用作润滑系统润滑泵,在液压系统中作循环泵、冷却泵、供油泵、液压泵,在燃烧系统中作喷燃泵,在油库作输送倒灌泵。
●在油轮、货油船舶、商船和许多战斗舰艇的轮机舱上,港口码头原油管道服务以及驳船与船舶的采集、增压和装载中,用做输送、增压、燃油喷射和主机润滑泵、主机滑油泵、润滑油泵以及船用液压装置泵、船用液压泵、锚机液压绞车驱动泵等也广泛使用三螺杆泵,
●在油田以及海洋平台等工业领域也有广泛的应用,输送原油,乳胶液等,
三螺杆泵选型时,要尽可能详尽地了解泵的使用条件,除运行参数,如流量、压力须要弄清楚之外,输送的介质的特性如介质的腐蚀性,含气量含固溶物的比率及固体颗粒的大小以及介质的工作温度、粘度、比重对泵内过流元件的腐蚀性等和泵装置的吸入条件,安装条件均要了解。
