引言我所研制的WLF106A 型电液伺服阀在国家重点工程和一些重要的工业部门进行过大规模的工程应用试验,并取得了重要的成果。本文利用这项典型产品的工程应用试验数据,参照“航空机载设备技术寿命和可靠性评估的一般程序和方法”对伺服阀的技术寿命进行评估,初步确定了该阀的技术寿命的平均值,同时对电液伺服阀在工业应用中的失效准则和失效模式作了一些探讨。WLF106A 电液伺服阀简介该产品是一种力反馈型流量控制电液伺服阀。主要用于武钢1700轧钢机液压压下控制系统,也可用于其它工业部门。其结构原
Introduction WLF106A electrohydraulic servo valve developed by me has carried out large-scale engineering application tests in key national projects and some important industrial sectors and has achieved important results. Based on the engineering application test data of this typical product, the technical life of the servo valve is evaluated with reference to the “General Procedures and Methods of Airborne Equipment Technical Life and Reliability Assessment”. The average technical service life of the valve is initially determined At the same time, the failure criterion and failure mode of electro-hydraulic servo valve in industrial application are discussed. WLF106A electro-hydraulic servo valve Introduction This product is a force feedback type flow control electro-hydraulic servo valve. Mainly used in Wuhan 1700 rolling mill hydraulic pressure control system can also be used for other industrial sectors. Its original structure
