Pressing screw screw bottom diameter and pitch circle diameter change form stepped screw shaft, otherwise, the step of forming a non-helical axis. The pressing screw pitch of the screw shaft pusher will change the speed change. Several screw bottom diameter and pitch different from the ring and pressing screw together, set in a pressing shaft to fight the system to become a gradually decreasing pitch, screw bottom diameter of the screw shaft increases. It consists of pressing the shaft and shaft sleeve in pressing section seven pressing bolts and pitch circle of six components. The first section is headed pressing screw thread, its role is to accelerate the advance of the preform; pressing the end of the second quarter tapered screw press Nanyang Which is good, it tapered end of the first paragraph squeeze cage phase fit, thus composed the first pressing system. Section VII from pressing screw to screw the screw pressing base diameter gradually increases, forming a second press systems. The first five laps from the pitch circle of flat, second, third, fourth, six from the pitch circle of the cone ring. Before using a hydraulic press, the first should be ready all the aids and containers, check and adjust the belt tightness. Then start the motor, the machine idling about 15min, check the speed of pressing screw shaft. Usually the speed should be around 33dmin. Do you want to pay attention to when the idle gear box gear meshing and sound normal, whether the individual bearing parts and motor properly. When press idle, the motor current should be around 3A. The current high price of oil press Nanyang, should immediately stop checks, adjustments and then boot. After the load is normal, about ready 50kg rapeseed or soybeans, ready to put into the hopper. Note: When you press the feed can not start too fast, otherwise the sudden increase pressure inside the chamber pressing, pressing screw shaft rotation does not move, causing blockage virgin bore, and even squeeze cage fracture, a major accident. So at the beginning of compression, the feed should be evenly slowly put into the hopper, so press were running together. So repeatedly, continuing more than 3 ~ 4h, so press the temperature was gradually increased, and even the risk of smoke (which is normal). At the beginning of the press virgin bore temperature is low, slowly twist the handle withered section Nanyang press studs on how much to increase the thickness of the cake Nanyang press, pressed into the billet while increasing moisture, temperature bore to be squeezed . Rose to about 90 ℃, normal operation after the press, the cake thickness can be adjusted to 1.5 ~ 2.5mm, and tighten the nut tightened.
