Maintenance should be checked after (a) every 50 hours lubrication, gearbox oil cup above shall not oil, pressing screw shaft bearings should be adjusted within the screw adjustment screw butter filling a hole in each class, non-dry grinding. (B) Run oil each site should prevent intrusion of dust and other impurities, the annual need to check the gearbox oil quality time, detect deterioration, replace all the oil. (C) when the press was reduced, a cake or the oil is not normal, should be squeezed out of the screw shaft, check pressing screw, cage bars, a cake ring wear, wear parts must be replaced. After the end of the (four) class work, the machine should be removed biscuit, clean the machine surface dust, grease. After long-term storage (five) production season, there should be a maintenance and pressing screw, cage bars, a re-oiled cake circle washable, dry place. How to use the correct speed is because the oil press and press the pressing screw diameter matched general smaller press, screw speed of 100-200 per minute, in turn, is a medium-sized oil press keep spiral per minute The speed in the range of 30-50 rpm, which means low speed press, production rate, long press time, the oil rate will be higher. A cake circle generally about 0.5-1.5 mm gap, little pressure, and will affect oil yield, but the size of the gap should have a certain limit, if the gap is too small, it will cause high pressure, fuel burned, broken shaft plug the other accidents. Before formally pressed into oil-bearing crops, should be allowed to press idling rotation for 3-5 minutes, then put the cake or even a small amount of feed material, the purpose is to improve the bombing bore through friction temperature, this should also be observed and adjust the cake mouth clearance. Avoid feeding uneven, so press the load suddenly rises, causing blockage. General body temperature at 60 degrees Celsius can be out of oil. Proper use of press equipment, you need to press the device model, performance, features, and press the principles have to understand.
