1、煤矿液压钻机试验台 中文摘要 本设计是为了满足普通煤矿用液压钻机出厂时进行参数检测而制作。用于检测出厂钻机的动力头实际输出功率以及实际的工作效率。本设计中采用转矩转速仪进行测量,由于所测量的钻机为低速大扭矩液压马达,转速太低,所以其驱动负载能力不够,因此,本设计专门为其设计了一个增速装置,用来提高其对所驱动液压的输入转速。由于转速转矩仪不能承受轴向力,因此本设计将增速器固定,使其承受所有的轴向力,其他装置也固定于实验台架上。本装置采用节流阀调速加载,结构简单,操作方便。输出系统采用8255并行接口电路连接打印机,可直接打印数据。关键词:煤矿,钻机,液压试验台Experiment the set
