现将WJD-0.75型铲运机几年来出现的典型故障、故障原因、排除方法及经验教训加以总结,从而有利于提高铲运机作业量和延长设备寿命。1.转向失灵在垦利黄河河务局工程处使用的几台铲运机中,都出现过转向失灵故障,方向盘转不动,或者用力才能转动一点。转向是由液压转向器控制的,先以为液压转向器内部机械卡死,拆开转向器,没有发现任何零件脱落卡住现象。再检查发现转向器阀块的进油口有许多小块颗粒
The WJD-0.75 scraper now typical faults, failure causes, troubleshooting methods and lessons learned are summarized, which will help improve the scraper operation and extend the life of equipment. 1. Turn failure In Kenli Yellow River Works Bureau Engineering Agency several scraper, there have been failure to turn the steering wheel, the steering wheel can not move, or force can be rotated a little. Steering is controlled by the hydraulic steering gear, first think that the hydraulic steering internal mechanical stuck, open the steering gear, did not find any parts off the stuck phenomenon. Then check the steering valve block has many small particles into the oil inlet
