介绍应用单片机8098和“流量—压差变化—位移校正”原理控制比例溢流阀排油流量实现负载传感的方法。该方法使只能控制系统压力的比例溢流阀具有三通比例流量阀和比例溢流阀两个阀的功能,且比采用三通比例调速阀的系统节能效果更好。
Introduce the application of singlechip 8098 and “flow rate - differential pressure change - displacement correction” principle of proportional relief valve discharge flow control method to achieve load sensing. The method makes the proportional relief valve that can only control the system pressure have the functions of two valves of the three-way proportional flow valve and the proportional relief valve, and has better energy-saving effect than the system using the three-way proportional control valve.
