Virgin material in advance of the actual state of motion is very complex. It has received a lot of resistance acts. These resistance comprising: an inner friction between the friction surfaces of virgin aggregate particles squeeze cage and screw shaft between the outer surface of the virgin material relative to the movement; the pressing screw interrupt, washer shape bore scraper and other mutations or squeezed for juice resistance material is formed; compression resistance when pressing bore space narrowing (including adjusting the resistance caused cake ring) and the like. The role that the actual result of the resistance movement in the virgin material virgin bore no longer as to promote uniform like screw conveyor, its speed of movement not only numerically, but also the direction of the different sections are constantly changing. Measured by scratches cage bars of each section, or with a wooden model of X-ray photography Xinxiang press equipment, have confirmed the trajectory of virgin material particles is an ever-increasing spiral pitch, it is precisely the pressing screw pitch Variation opposite. This shows the result of resistance from axial differentials getting bigger Xinxiang press, and the radial differentials getting smaller. The length of the press but also because of the press of time varies newness pressing screw. The new assembly pressing screw thread edges complete press Xinxiang brand, promoting strong material back less embryo, squeeze time will be shorter. And when the old pressing screw badly worn advance weak back embryos increases, squeeze some time president. When replacing the pressing screw it can be used along with the old and new, in order to maintain proper press time Xinxiang press manufacturer, so that the material is pushed forward speed appropriate to maintain the normal position of the oil. In addition, reduced feed press strength, wear, abrasion blade cage bars will result in extended press time. Structure and the structure of virgin material virgin bore - all affect the mechanical properties of varying degrees of press time; Xinxiang press manufacturers _ Goodwin machinery (certified) _ press the Nanyang Xinxiang City, Qi Feng Machinery Co., Ltd. provided.
