我国早期生产的W501挖掘机和波兰海鸥牌挖掘机液压操纵系统都使用蓄油器。由于保养不好,用油未经净化处理,常常造成不正常磨损,影响施工进度。我们采用6120Q-1发动机气缸套代用的办法,可以收到较好的效果。先将蓄油器拆下,再把蓄油器下部的缸体拆下,取出活塞与皮碗,便能很清晰地看出磨损程度。磨损较轻时,更换干净的油仍可继续使用;严重磨损时,活塞与缸壁处会被拉出多条纵向沟槽,皮碗也被拉破。此时,可将被拉
Both the W501 excavator and the Polish Seagull excavator hydraulic control system produced in China used oil accumulators. Because of poor maintenance, the oil is not purified, often causing abnormal wear and affecting the progress of construction. We use the 6120Q-1 engine cylinder liner replacement method to receive better results. Remove the oil reservoir first, remove the cylinder from the lower part of the oil reservoir, remove the piston and the bowl, and you can clearly see the degree of wear. When the wear is light, the replacement oil can still be used; when it is severely worn, multiple longitudinal grooves will be pulled out of the piston and the cylinder wall, and the leather cup will be broken. At this point, it can be pulled
