数字控制技术和总线技术都是信息技术（IT）知识范畴。技术应用拓展了液压机物理模型的深层次理解及微电子控制分析双动拉伸液压机。它不能改变液压机本身的特性单柱液压机，只是处理液压机参数更方便更容易。但是需要注意的关键是，液压机控制是专业性强的技术工作，现在以至将来仍然要靠液压机工程师而不是电工程师来完成。

第二拉伸液压机，用简单的辅助部件诊断液压机液压元件故障的辅助方法。阻止泄漏。如果液压阀元件的油出口和气缸出口被堵塞，则可以诊断这些液压元件的泄漏。如果液压阀元件被冲头反转，则可以诊断方向阀是否已经溢出，例如堵塞，并且阀芯就位。该方法可以在不拆卸液压部件的情况下诊断液压部件框架式液压机。它避免了过度拆卸工作，缩短了故障诊断时间，便于快速诊断，尤其适用于大型气缸密封等故障。
