本文对目前市场上一些气控液压换向阀的液压工作原理进行了分析,对气控液压换向阀的一些具体细节问题进行了探讨,以此为自卸车液压系统设计者提供一些可供参考的思路。气控液压换向阀作为自卸车液压系统的一个重要组成部分,其性能的优劣决定了自卸车货箱的举升性能。尽管自卸车的液压系统与其他专用汽车相比较为简单,但是因其自身的一些工作特点决定了该液压系统不同于其他系统,其恶劣的工况易导致系统内压
In this paper, some working principle of the hydraulic control valve on the market is analyzed. Some specific details of the pneumatic control valve are discussed, which can be used as a reference for the hydraulic system designer of the dump truck Train of thought. As an important part of the hydraulic system of dump truck, the pneumatic control valve has its performance of determining the lift performance of the dump truck. Although the hydraulic system of Dump Truck is relatively simple compared with other special purpose vehicles, because of some of its own working characteristics, it determines that the hydraulic system is different from other systems, and its poor working conditions can easily lead to system internal pressure
