振动压路机液压系统一般具有行走、振动和转向三个独立的系统。为使系统工作可靠,除了要保证液压元件本身的质量外,还必须解决液压系统及元件的污染控制问题。一、液压系统方案设计中的污染控制根据系统元件对污染控制的要求及振动压路机有关行业标准来制定切实可行的防污染措施。1.进行分级控制根据液压系统中三个系统元件的不同精度要求、系统的压力及控制精度来确定液压系统的污染控制等级,进行分级控制。由于行走系统采用的轴向柱塞泵和柱塞马达对污染很敏感,所以在该系统设置精度较高的过滤器,使油液
Vibratory roller hydraulic system generally has walking, vibration and steering three separate systems. In order to make the system work reliably, in addition to ensuring the quality of the hydraulic components themselves, it is also necessary to solve the pollution control problems of the hydraulic system and components. First, the hydraulic system design pollution control system components based on pollution control requirements and vibration roller roadmaps to develop practical anti-pollution measures. 1. Grading control According to the hydraulic system of the three system components of different accuracy requirements, the system pressure and control accuracy to determine the hydraulic system pollution control level, the grading control. Because of the axial piston pump and plunger motor used in the walking system, which are sensitive to contamination, a filter of high precision is set in the system so that the oil
