The shaftless screw conveyor can help us realize the transfer of powder or granular materials. The use of this equipment saves our labor costs and improves our work efficiency. But any equipment has requirements during use, today I will tell you about its use requirements. Do a good job in the daily maintenance of the conveyor. During use, check the working status of each part of the screw machine and pay attention to whether the fasteners are loose. If the parts are found to be loose, tighten the screws in time to make them firm again. The cover of the screw machine should not be removed when the machine is running, so as to avoid accidents.
Before the shaftless screw conveyor is started, the material cannot be discharged into the feed port. The screw conveyor should be started when there is no material in the casing, and the no-load start can make the equipment meet the performance. In order to meet the requirements of the no-load start of the screw machine, the conveyor should stop feeding before stopping, and stop running after the material in the casing is exhausted. During the initial feeding, the feeding speed should be gradually increased until it meets the rated conveying capacity, and the feeding should be uniform, otherwise it will easily cause the accumulation of conveyed materials and overload of the driving device, thus affecting the service life of the screw conveyor. The material to be conveyed cannot be mixed with hard bulk materials, so as to avoid screw jamming and damage to the screw machine.
The structure of the shaftless screw conveyor is simple, but in the process of specific operation, several problems are often encountered. In addition to improper human operation, the machine is damaged, and the equipment itself also has a wear cycle. Reasons for the sudden stop of the conveyor:
1. The material to be conveyed is too large, and the material cannot pass through the hanging bearing in the middle smoothly, and the resistance of the material at the middle bearing is too large. Cause the screw conveyor to stop suddenly.
2. The blockage of materials in the conveyor can also cause the motor to overload and cause the machine to stop. At this time, the material in the screw conveyor must be cleaned.
3. The resistance at the intermediate bearing is too large and the seal is damaged. Materials entering the bearing cause the bearing not to rotate or the bearing to be damaged.
4. The bearing of the reducer is burned. At this time, a new part needs to be replaced.
