摘要
针对煤矿现场大功率的自动钻机的需求,丰富自动钻机产品类型,基于ZYWL-4000SY型分体履带式自动钻机设计研发了ZYWL-6000Y型整体履带式自动钻机的动力总成。参照6000型钻机标准,完成了大、小泵及电动机的选型,并对系统发热量进行计算,选择合适的冷却器。通过实验表明:该动力总成的输出参数达到6000型钻机标准,并采用负栽敏感系统有效减少系统发热量,待机时间明显延长。
Aiming at the demand of high—power automatic drilling rigs in coal mines and increasing the product series of automatic drilling rigs,the power assembly of ZYWL-6000Y integral caterpillar automatic drilling rig was designed and developed on the basis of ZYWL-4000SY split caterpillar automatic drilling rig.According to the standard of 6000 type drilling rig,the selection of pumps and motors was completed,and the system calorific value was calculated,and the appropriate cooler was selected.Experiments show that the output parameters of the powert assembly are up to the 6000 drilling rig standard,and the load sensing system can effectively reduce the system calorific value and prolong the standby time.
