|
摘要
针对煤矿井下行走工况条件恶劣,煤矿用履带设备行走时经常存在发热的问题,设计了一种行走功率损失试验系统。介绍了液压系统的基本组成和控制特点,通过对功率损失的理论分析,给出功率损失的主要影响因素,并通过对主要参数进行监测,得到各项行走功率损失的实际影响程度,与理论分析进行对比,得到测试数据和理论计算一致。设计的行走功率损失试验系统可有效地反映出设备的实际功率损失,为煤矿用履带设备行走液压控制系统的设计提供了参考。
In view of the bad working conditions of the coal mine,the coal mine crawler equipment often has the problem of overheating when walking,and a walking power loss test system has been designed. The basic composition and control characteristics of the hydraulic system are introduced. Through the theoretical analysis of the power loss,the main factors affecting the power loss are given. Through the monitoring of the main parameters,the actual influence degree of various walking power loss is obtained. Compared with the theoretical analysis,the test data is consistent with the theoretical calculation. The designed walking power loss test system can effectively reflect the actual power loss of the crawler equipment,and provide reference for the design of the hydraulic control system for the walking equipment of the coal mine.
