【本刊讯】根据煤炭、一机两部下达的任务,洛矿所与兖州煤矿设计院、平顶山选煤所和开栾煤研所一起承担了35米~2大型筛下空气室跳汰机的试验研究任务。为赶超西德先进水平,在35米~2筛下空气室跳汰机上采用了新型的数控电磁风阀来替代卧式机械风阀装置,经过两年多的试验研究,取得了试验室单缸带负荷试验和工厂空负荷联动试验的初步成功。数控电磁风阀,是利用数控电子装置通过十个电磁阀分别控制十个气缸来完成
According to the tasks assigned by coal and one unit and two units, Luoyang Coal Mine and Yanzhou Coal Mining Design Institute, Pingdingshan Coal Preparation Plant and Kuan Luan Coal Research Institute jointly undertake a 35m ~ 2 large-scale air chamber jigger Experimental research task. In order to catch up with the advanced level in West Germany, a new type of electromagnetic electromagnetic air valve was adopted instead of the horizontal mechanical air valve device in the air chamber jig of 35m ~ 2 sieve. After more than two years of experimental research, Initial success of the joint test of cylinder load test and factory empty load test. NC electromagnetic damper is the use of digital electronic devices through the ten solenoid valves were controlled by the ten cylinder to complete
