提高混凝土泵车液压传动效率与控制精度的方法

On the Method to Improve the Hydraulic Transmission Efficiency and Controling Precision of Concrete Pump Car

针对混凝土泵车的液压传动系统与液压控制系统中存在的传动效率问题及液压控制精度问题展开讨论,分析出液压传动中影响传动效率的主要原因是液压系统的泄漏问题,并分析了泄漏发生的原因,提出防止泄漏的解决办法;指出了采用电液比例阀与电液伺服系统来提高控制精度是混凝土泵车液压控制系统的发展方向。

The problems of the hydraulic transmission efficiency and the hydraulic control precision for conrete pump car are discussed . The study shows that the main reason of the influence hydraulic transmission efficiency is the leakage of hydraulic system and put forward the solution to prevent leakage. It pointed out the development direction of the hydraulic control system of concrete pump car.
