Development of Protection Equipment for Lost Power of Certain Electro-hydraulic Servo System

针对泵控马达位置伺服系统断电保护难题,确定了组合阀式断电保护装置技术方案,完成了该装置的生产、装配,并对其功能、性能进行实验。结果表明:该装置技术方案设计合理,各项指标达到设计要求,工作稳定可靠,有较大的推广价值。

Aimed at difficult problem of lost power of pump-control-motor hydraulic position servo system for being out of control, the technical scheme of protection equipment for lost power was designed with combinational valves. The manufacture and assembly of this equipment, and test of its performance and function were completed. The results show that the design scheme is reasonable, every index meets the design request, and the new equipment works reliably and stably, which is worth being promoted to society.
