摘　　要：研究影响三螺杆泵使用寿命的本质因素,优化结构设计,并能为后续的深入研究建立合理的理论基础,对螺杆与介质间的互作用进行了较透彻地分析,并给出了基本的求解公式,设计者可以根据此分析结果进行螺杆结构的优化设计。The essential factors affecting the life span of the three screw pump are researched, optimize the structural design and establish the rational theoretical basis for the future research by analysing clearly and objectively the mechanical influnce from the interating between the three screw rod and the transport mediator in the three screw pump. On the other hand , the basic solution formula was given which the designer of the three screw pump can design the proper structure of the screw rod in the pump by applying it.
