振动一般可以用以下三个单位表示:振幅mm、振动速度(振速)mm/s、振动加速度mm/s2。
mm振动位移:一般用于低转速机械的振动评定;mm/s振动速度:一般用于中速转动机械的振动评定;mm/s2振动加速度:一般用于高速转动机械的振动评定。
垂直,轴向,水平三个面对设备进行测振
振幅理解成路程,单位是mm;把振速理解成速度,单位是mm/s;振动加速度理解成运动加速度,单位mm/s2。
速度描述的是运动快慢;振速就是振动快慢,一秒内能产生的振幅。
振幅相同的设备,它的振动状态可能不同,所以引入了振速。
位移、速度、加速度都是振动测量的度量参数。就概念而言,位移的测量能够直接反映轴承固定螺栓和其它固定件上的应力状况。
不同转速的转机振动合格标准是什么?
额定转速750r/min的转机轴承振动值不超过0.12mm,额定转速1000r/min的转机轴承振动值不超过0.10mm,额定转速1500r/min的转机轴承振动值不超过0.085mm,额定转速1500r/min以上的转机轴承振动值不超过0.05mm。
窜轴值不超过4mm。
