摘要
对护顶机支臂缸的受力情况进行了计算,并对其结构特点进行分析,总结了常用平衡回路的特点与不足。同时,介绍了FD平衡阀的特点,针对护顶机支臂缸的受力特点设计了具有FD平衡阀的平衡回路。实践证明,该回路能够满足设计要求,实现设计目的。
Calculating forces of the supporting cylinder in the roof-protecting machine and analyzing its structural characteristics the article summarizes characteristies and insufficiencies of the common balance circuit. Meanwhile, it introduces features of FD balance valve and designs the balance circuit with FD balance valves according to the force characteristics of the cylinder. The practice proves that the circuit could satisfy the design requirements and realize the design goal.
