3、GNFThick stainless steel pump一、 原理和特点One、Structure and features我厂生产的CNF系列单螺杆浓浆泵属于容积式泵，它的主要工作部件是偏心螺旋体的螺杆（称转子）和内表面呈双线螺旋面的螺杆衬套（称定子）。其工作原理是：当电动机带动泵转动时，螺杆一方面绕本身的轴线旋转，另一方面它又沿衬套内表面滚动，于是形成泵的密封腔室，螺杆每转一周，密封腔中的液体向前推进一个螺距，随着螺杆的连续转动，液体以螺旋形式从一个密封腔压向另一个密封腔，最后挤出泵体。I plant the CNF series single screw pumps are conce
4、ntrated pump, its main component is the eccentric helical screw body (called the rotor) and the inner surface of double helical screw bushing (called the stator). Its working principle is: when the motor drives the pump rotation, the screw will rotate around its own axis, on the other hand it rollin
