摘要
针对EBZ-200掘进机在使用过程中出现的发热量高、损耗大和液压油大量流失等状况,对冷却系统和马达、马达座进行改进。现场应用表明:改进后解决了液压系统持续高温和星轮马达掉落的问题,验证了改造的合理性。
In view of the high power consumption,high loss and large loss of hydraulic oil in the use of EBZ-200 roadheader,the cooling system and motor and motor base are improved.Field application shows that the improved hydraulic system solves the problems of continuous high temperature and star wheel motor dropping,which verifies the rationality of the transformation.
