我公司一台KA—300F型30t起重机,在油田的施工中,出现了底盘侧不能启动发动机、挂挡不能行走、故障灯闪烁、整机仅能用变速器紧急开关缓慢移动的故障。由于该机自动化程度高,原始资料缺乏,为此,我们对该机的结构、原理进行了详尽的分析,并使其在较短的时间内恢复了设备原有性能。 1.故障诊断分析 动力传动系统由机械控制机构、液力传动机构和电器元件控制三部分
A KA-300F 30t crane of our company appeared in the construction of the oilfield, the engine can not be started on the side of the chassis, the gear can not walk, the fault light flashes, and the whole machine can only move slowly by the emergency gearbox. Due to the high degree of automation of the aircraft, the lack of raw data, for which we have carried out a detailed analysis of the structure of the aircraft, and make it restore the original performance of the equipment in a relatively short period of time. 1. Fault diagnosis and analysis Power transmission system consists of mechanical control mechanism, hydraulic transmission mechanism and electrical components control three parts
