If the virgin material virgin material internal friction and particle-particle friction and squeezed between the outer surface of the shaft between the particles and the friction material than virgin pressed cage between the surface, then the virgin material generated with the shaft rotation. When screw press work, pressing material rotates with the shaft movement is not normally allowed. In pressing cage surface resistance Henan new press, squeeze and squeeze cage material particle surface to offset the large rotating with the shaft to force weeks, but in the middle layer, pressed material particles depends mainly on the role of the internal friction of Henan oil extraction machine equipment, the resistance is small, especially in the feed zone, the internal friction between loose particles virgin material smaller Henan oil press factory, then it is easy to produce virgin material rotating with the shaft phenomenon. In addition, the friction of virgin and extra virgin material between the shaft surface is also prone to rotating with the shaft. Thus, each radial layer of virgin material with the rotation of the shaft is inconsistent. In order to prevent the phenomenon of virgin material with the shaft in the screw press means pressing a blade bore and shaft surface finish, and when squeezed juice bar cage surface means it has a "spine sex." Automatic press protection: 1, lasting downtime, should wipe the dull, oiled, and close the shield. 2, the pressure oil necessary automatic oil pump on the filter, the concentration is not too large, the best animal oil, to stop the use of gasoline, kerosene and other flammable oil. 3, automatic oil pump and the handle adjacent the pin, to always add lubricating oil, reducing wear and tear. 4, automatic oil should be used indoors as much as possible, in order to avoid the wind and sun, causing oil pollution. 5. To link within the automatic oil tank clean, about three months to a clean tank, and replace with new oil, or pull out the filter box before use, impurities in the oil pump wear will cause the oil infarction, dull things affect performance.
