【本刊讯】由洛矿所、洛矿工人大学和洛阳气动元件厂共同奋战,经过两年的试验室和工厂样机试验研究,克服了不少困难,第一次将膜片式气动元件应用于跳汰机,取得了初步成功。跳汰机是选煤厂的主要选煤设备之一,过去一直采用卧式机械风阀,这种阀体积大、重量重、加工复杂,对水流脉动的频率和周期只能进行有限地调节。国外
【News from】 Luo mine, Luo mining workers University and Luoyang Pneumatic components plant to work together, after two years of laboratory and factory prototype test study, to overcome a lot of difficulties for the first time the diaphragm pneumatic components application In the jig, made initial success. Jig is one of the main coal preparation equipment in the coal preparation plant. In the past, the horizontal mechanical damper had been used. The valve is large in volume, heavy in weight and complicated in processing. It can only regulate the frequency and period of the pulsation of water in a limited way. foreign
