摘　　要：钻井液中含有的研磨性固相颗粒,会对泥浆泵凡尔及凡尔座产生侵蚀性磨损。凡尔总成的耐久度取决于其材质、结构和泥浆流速。文中分析了几种提升泥浆泵凡尔总成耐久度的方法,包括根据工况选用合适设计的凡尔,凡尔座基底选用推荐的合金材料,使用特定的接触面表面硬化工艺。The abrasive solid particles contained in the drilling fluid will cause erosive wear to the valve and valve seat of the mud pump.The durability of the valve assembly depends on its material,construction and mud flow rate.This paper analyzes several methods for improving the durability of the valve assembly of the mud pump,including selecting a valve with a suitable design according to the working conditions,selecting the recommended alloy material for the valve seat base,and using a specific surface hardening process for the contact surface.
