开发一种在核心技术上具有自主知识产权的H型偏零开口液脉冲控制伺服阀,利用结构设计和液压油路控制,实现高效节能液控振动挖掘机的振动挖掘方式,将传统的静态挖掘力变革为动态瞬间大的冲击挖掘力,目的是解决挖掘机在硬地面、矿山碎石地面、山石地震等复杂地面施工中出现的效率低、耗能高等问题,同时克服传统伺服阀的加工困难、造价高、抗污染能力差、滤油回路设计复杂、滤油器制造困难等问题。
Development of a H-type zero-opening liquid pulse control servo valve with independent intellectual property rights in the core technology, the use of structural design and hydraulic circuit control to achieve high-efficiency energy-saving vibration-controlled hydraulic excavator excavation method, the traditional static excavation The purpose of the force change is to solve the problems of low efficiency and high energy consumption in complex ground construction of hard ground, mine gravel, rock and earthquakes, etc., and to overcome the processing difficulties of traditional servo valves , High cost, poor anti-pollution ability, complex design of oil filter circuit, difficulties of oil filter manufacturing and other issues.
