近年来,在公路、市政建设、铁路、水利和林业等部门开始广泛采用振动压路机来进行振动压实工作。振动压路机在行走系统中,广泛采用了斜盘式轴向变量泵和马达组成的闭式静液压传动系统。这套系统经常处在较高压力下工作,元件的精度高,对液压油的污染比较敏感。从主机厂的生产和施工用户的使用情况来看,这套系统因存在液压油的污染问题而经常出故障。因此,解决振动压路机液压系统的污染控制问题,已成为压路机行业的一项攻关项目。为有效地滤除液压系统的污物,保护液压
In recent years, vibratory rollers have been widely used in highway, municipal construction, railway, water conservancy, and forestry departments for vibration compaction. Vibratory roller In the walking system, a closed hydrostatic transmission system consisting of a swashplate axial variable displacement pump and a motor is widely used. This system is often operated at higher pressures, with high component accuracy and sensitivity to hydraulic oil contamination. From the use of the production and construction users of the main plant, this system often fails due to the contamination problem of hydraulic oil. Therefore, solving the problem of pollution control of the vibratory roller hydraulic system has become a key project for the roller industry. To effectively filter the dirt from the hydraulic system and protect the hydraulic pressure
