挖掘机用高压多路阀研制的关键技术

Developed Key Technologies for High-pressure Valve in Excavator

随着工程机械挖掘机行业的飞速发展,作为挖掘机液压系统的主要核心液压元件,高压多路换向阀研制的关键技术得到了越来越多的重视。结合某公司生产的中型挖掘机用高压多路换向阀,从设计、铸造、加工3方面阐述多路阀研制过程中的关键技术。

With the rapid development of construction machinery excavator, as the main core of excavator hydraulic system hy- draulic components, developed key technologies of high pressure directional valve are getting more and more attention. Combining with a high-pressure directional valve used in medium-sized excavator, from design, casting, processing three aspects, the key techniques in multi-way valve development were elaborated.
