液压万能试验机液压元件安装
液压万能试验机是一种载荷大、实用性高的万能试验机，其液压系统的液压元件在安装时要注意以下四个方面。
第一，液压万能试验机的液压元件在安装之前，要用煤油清洗，试验压力可取工作压力的两倍，或取最高使用压力的一点五倍。试验时要分级进行，不要一下子就升到试验压力，每升一级检查一次。
第二，检查进出油口处的密封圈是否合乎要求，安装前密封圈应突出安装平面，保证安装后有一定的压缩量，以防泄漏。
第三，方向控制阀（用以改变管道内气体或液体流向的控制元件叫方向控制阀）应保证轴线呈水平位置安排。
第四，液压万能拉力试验机液压系统的各固定螺钉的拧紧力要均匀，使元件的安装平面与元件底板平面很好的接触。
