工业用电液伺服阀故障统计分析和使用维护建议

Fault Statistical Analysis and Maintenance Suggestions of IndustrialElectro-hydraulic Servo Valve

在工业领域中,常用的电液伺服阀主要有直驱式伺服阀、喷嘴挡板两级伺服阀、射流管两级伺服阀以及三级伺服阀。根据伺服阀维修业务中收集到的1176例伺服阀故障,对常见电液伺服阀故障原因进行了分析、归类统计和研究。为工业用电液伺服阀的选型提供了参考,也针对电液伺服阀的使用维护提出了建议。

In the industrial field,the commonly used electro-hydraulic servo valves include direct-drive servo valve,nozzle flapper two-stage servo valve,jet pipe two-stage servo valve and three-stage servo valve.According to the 1176 cases of servo valve failures collected in the service of servo valve,the causes of common servo valve failures are analyzed,classified and statistically studied,which provides a reference for the selection of electro-hydraulic servo valves in the industrial field,and also puts forward suggestions for the use and maintenance of electro-hydraulic servo valves.
