When press the maintenance of normal oil, feed must be kept evenly, not too little or too much material off idle. At this point the machine load to normal, smooth, rhythmic sound. The cake and smooth, low segment almost no residue, a small amount of high-pressure diesel segment, but the proportion of oil residue is not more than 10%, extra virgin bore a temperature of up to 120 ℃ -180 ℃, the cake mouth emitting smoke should discharged from the smoke pipe through the shroud. Squeeze the hot cake to promptly spread out, do not rush to beat heap or shipment, otherwise it will produce a natural phenomenon. When the continuous working time is longer, machine temperature is too high, it should be taken, such as electric fan blowing cooling measures. Press operating essentials required to check all parts of filling oil all parts are tightened Henan spiral press, operating handle is flexible flapper moving large pulley by hand, check the machine for loose or stuck phenomenon . If abnormal loosen and remove the lock nut, the pressing screw shaft screwed to the dead point, and then return 3-4 laps, then a half circle forward, in order to maintain the gap pressing screw with a cake circle. Adjust the belt tension. Dial material driven pulley shaft rotation is a bivalent sheaves, if available slag serious small sheaves. Open the electrical box door, the air inside the power switch in the close position, start the motor, check the direction of rotation of large sheaves is consistent with the direction of the mark. Adjust the temperature controller: adjust to press the desired temperature 150-200. C (based on oil may be). Host twist heating switch the machine to heat up, then the temperature controller on the green light, red light is off, when the engine temperature rises to a set temperature, the red light, green light is off. The temperature of the machine is automatically controlled and maintained at a set temperature 150-200. C, low winter temperatures, the heating switch is turned to the oil pan, the oil pan temperature, easy oil shed. After feeding should be turned slowly and evenly, the feed can not start too fast, or more, when the little spiral press, or may cause blockage and stuck virgin bore other machinery accidents. Start feeding the cake should be thicker, after a normal cake, machine temperature reaches 150-200. C before the embryo into the feed hopper normal press. After the machine run out of cake to observe the situation, such as no cake can be pressed again to exit l screw a 2 laps, as not a cake, you should stop to check, remember to prevent backsliding. Hand moving large pulley Hubei spiral press manufacturers, reversing a few laps and then boot. Troubleshooting and then be pressed. L during normal operation of a 2 mm thick cake and a tile-like, pinching sticky, wrinkled outer surface with no traces of oil. Spiral press principle, screw press, Goodwin machinery provided by Nanyang City Goodwin Machinery Co., Ltd. Nanyang City Goodwin Machinery Co., Ltd.
