The situation considered here is that the surface of the spool of jet pipe servo valve is a conical surface that with a certain taper caused by the machining error and the spool mounting with the valve sleeve eccentrically. The models of the contamination wear and the durability life of jet pipe servo valve are established by using the theory of abrasive wear, the maximum allowable leakage of jet pipe servo valve and the distribution of the pollution particles in the hydraulic system. At last the models are verified by an example and the influencing factors of the servo valve contamination wear are analyzed. Results show that mathematical models are well agreed with wear processes, and durability life meets the national standard. At the same time, the durability life of jet pipe servo valve is longest when the spool has no eccentricity and taper. While the surface of the spool of jet pipe servo valve has a certain taper caused by the machining error and the spool mounting with the valve sleeve eccentrically, the durability life of jet pipe servo valve is the shortest. The results are useful for the prediction and calculation of wear and durability life of jet pipe servo valve and have an important role on the anti-wear design of jet pipe servo valve.
