单纯用动力制动下放位能负载及其调速

Power Brake Falling Load and Speed Regulation

矿井单滚筒提升绞车或双滚筒用做单钩提升下放重物时,原TKD电控系统不能满足其要求。为此,利用动力制动直接下放位能负载使其控制更加趋于合理,保护得到很好的利用。

When hoisting falling weight in mine shaft applying single barrel hoist or double barrels single hook hoist, the original electric control system TKD can not satisfy the requirement,so applying power directly brake falling load with potential energy,which makes control more reasonable and protectional function better used.
