最近,一种新型自动开门快速卸煤设备 MEC 风缸活门装置在美国投入运用,它为铁路煤车卸车操作提供了可变性和耐久性。这种由矿山部门制造的卸煤装置可在几秒钟内平行地打开每扇车门,用18s 将100 t 的煤全部卸干净,再用几秒钟的时间将每扇车门同时关好。MEC 自动开门卸煤装置的组成可分为三个主要组成部分:空气系统、车门机关和电气系统。空气系统由车门操纵风缸、园筒阀、滤尘器、储气罐和与车辆长度相当的4 cm 直径的供风管道所组成。从供风管道来的空气进入储气罐,再通过滤尘器
Recently, a new type of MEC automatic door opening and closing equipment was put into operation in the United States, which provided variability and durability for the unloading operation of railway coal cars. This unloading unit, made by the mines department, opens each door in parallel in seconds, removes 100 tons of coal in 18 seconds, and closes each door in seconds in a matter of seconds. MEC automatic door unloading unit can be divided into three main components: the air system, the door and electrical systems. The air system consists of a door-operated cylinder, a cylinder valve, a dust filter, a gas tank and a 4 cm diameter air supply duct of the same length as the vehicle. The air from the supply duct enters the gas tank and then through the dust filter
