1. The screw conveyor should be started without load, that is, when there is no material inside the casing, it can only be fed to the screw conveyor after starting.
During the initial feeding of the spiral conveyor, the feeding rate should be gradually increased until it reaches the rated conveying capacity. The feeding should be uniform, otherwise it may cause material accumulation and overload of the driving device, leading to early damage to the entire machine.
3. In order to meet the requirement of starting the screw conveyor without load, the conveyor should be stopped from adding materials before stopping, and the operation can only be stopped after the materials inside the casing are completely emptied.
4. Strong large pieces of material must not be mixed into the transported material to prevent the screw from getting stuck and causing damage to the screw machine.
5. Regularly inspect the working status of various parts of the screw conveyor during use, carefully check whether the fastening parts are loose. If the invention parts are loose, immediately tighten the screws and re tighten them.
6. It is necessary to carefully check whether the screws between the spiral tube and the connecting shaft are loose. If this phenomenon is discovered, it should be immediately stopped and corrected.
7. The machine cover of the spiral conveyor should not be removed during mechanical operation to avoid disorder.
Any abnormal phenomena that occur during the operation of the spiral conveyor should be checked and eliminated, and forced operation is not allowed.
9. The moving parts of the spiral conveyor should be regularly lubricated with oil.
① The reducer of the driving device should be lubricated according to its instructions.
② Lithium based grease is used in the bearing boxes at both ends of the spiral conveyor, with approximately 5 grams injected every two weeks.
③ The spiral conveyor suspension bearings are of M1 type. Among them, the 80000 type bearings are immersed in melted lubricating grease, cooled together with the grease, and reused after reinstallation; If the sealing ring is damaged, it should be replaced in real time. After one year of use, the above methods should be used again for maintenance, which can achieve excellent results.
④ The spiral conveyor suspension bearings should be of M2 type, and lubricating grease should be added to each shift. Each suspension bearing pad should be lubricated with about 5 grams of grease. High temperature materials should use ZN2 sodium based grease, and self-lubricating bearing pads should also be included in a small amount of lubricating grease.
