螺杆泵使用注意事项
下面介绍其它油泵不具备,而螺杆泵所*的特性。
(1)GD,(惯性力矩)小 ,螺杆泵的惯性力矩GDZ非常小。这是由于主动螺杆及从动螺杆的外径较小,对泵不必特别考虑动平衡问题。但是,由于电动机和联结器的GD“值为泵的数倍以上,因而在选定和加工泵时需充分注意这个问题。
(2)变频器驱动 螺杆泵为定容积型泵,所以近来多用变频器控制泵流量。特别是工艺流程中,采用了Pl及PID控制方式,这样可获得准确的流量.
在用变频器的场合,用于液压没备的螺杆泵所存在的问题是:泵在低速运转时噪声大。这是因为变频器产生的输入电流波形像商用电源那样不平滑,所以电动机转速发生变化,致使泵的排出压力脉功增大。
(3)汽蚀 泵的吸入压力降低会产生汽蚀,引起噪声和振动增大.这时不仅是排出端,吸入端的压力脉动波形也会大乱,排量随之减小。如果是液压用油.泵的吸入压力可达0.05MPa,所以吸入管路很容易渗入空气。因此在安装管路和过滤器时应特别注意密封问题。
人们一般不太了解螺杆泵,但实际上它的用途很广。今后液压设备还要向高压化发展,可能使用的液体种类也会增多,我们期待着螺杆泵的用途进一步扩大。
