电液伺服机构贮存延寿技术研究

The Research of Electro-hydraulic Servo Mechanism Storage Life Extension

电液伺服机构是控制系统的执行机构,其可靠性和寿命既关系到产品在贮存期内能否有效投入使用,又关系到产品的不合理报废造成的经济损失。电液伺服机构主要由电机、油泵、伺服阀、电位计、压力传感器、各类活门、金属结构件、密封件组成。由于其复杂的结构组成,对整机的加速贮存方法无法获得准确的影响因子,以往较多的是对个别元组件的加速贮存方法研究,以此推算出整机的贮存年限。本次技术研究工作基于自然贮存的电液伺服机构整机,通过试验摸清其元组件在规定贮存条件下质量变化规律,确定其贮存延寿方案,最后进行方案的实施及试验验证工作。研究成果可为同类产品的加速贮存技术提供宝贵信息,为同类产品性能变化规律的研究进行有益的探索。

Electro-hydraulic servo mechanism is the actuator of the control system,its reliability and longevity are not only related to the workability of the missile in its specified storage time,but also the economical loss caused by the unreasonable scraping of product.The electro-hydraulic servo mechanism is mainly composed of motor,oil pump,servo valve,feedback potentiometer,pressure sensor,all kinds of valve,metal structures,seal.Due to its complex structure,it is difficult to obtain accurate impact factor with the acceleration of the whole machine storage methods,and it is ever more research accelerated degradation for individual components,to calculate the storage life of the machine.This technical research work is based on the whole machine of electro-hydraulic servo mechanism in natural storage,through testing to find out the quality change rule of its component under the specified storage conditions,determine its storage life extension program,and finally carry out the implementation of the program and test verification.The research results can provide valuable information for the accelerated storage technology of the same kind of products and make a beneficial exploration for the study of the performance change of the same kind of products.
