W1001型挖掘机主卷扬的两套脚踏油压制动机构,原来是用人工在脚踏油缸处加油的,排气和加油都比较麻烦,又影响生产。在不增加易损件的前提下,通过试验,在1973年的产品上设计了一个单向阀自动加油装置,安装在抱闸油缸的 G3/8″螺孔上,靠自重向低处流,空气沿管道向高处排出,效果很好。 The two pedal hydraulic brake mechanisms of the main winch of the W1001 excavator were originally used to refuel at the pedal cylinder. Exhaust and refuelling are bothersome and affect production. Under the premise of not increasing the wearing parts, through tests, a one-way valve automatic oiling device was designed on the 1973 product, which was installed on the G3/8′′ screw hole of the holding cylinder and flowed to its lower position by its own weight. Air is discharged high along the pipeline and works well.
