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。
