摘　　要：设计一套微小流量电磁先导阀综合性能试验装置液压控制系统,实现对微小流量电磁先导阀单独进行液压测试,解决以往该阀必须与主阀组合测试的技术难题。可按照国家标准GB25974.3-2010《煤矿用液压支架第3部分:液压控制系统及阀》的要求,对电磁先导阀进行强度、寿命、背压安全性等性能试验。并利用蓄能器代替传统液压泵为先导阀测试提供动力,提高了测试效率,降低能源消耗。Designed small flow electromagnetic pilot valve hydraulic test control system, it could test comprehensive performance of small flow electromagnetic pilot valve individually based on GB25974.3- 2010“Powered support for coal mine-Part3： The hydraulic control system and valves”. It avoided the illness that this valve must be tested with main valve together in the past, it realized to test electromagnetic pilot valve performance individually. It could test electromagnetic pilot valve performance such as strength, durability, back-pressure safety. And it the used accumulator instead of traditional pump to provide power for the pilot test, improved test efficiency and greatly reduce energy consumption.
