How to effectively solve the tightness of screw conveyor

How to effectively solve the airtightness of the screw conveyor? The screw loading conveyor is a very versatile conveying equipment. It has simple operation and can complete the conveying operation stably and continuously. It adopts a structure supported by bearings at both ends, and it is easy to cause blades and blades during use. The seals of the shell, bearing and end seat are worn away, and the gap between the shaft and the end seat is relatively large. Because the gap between the shaft and the end seat is relatively large, the sealing effect is relatively poor, and the increase in the use time will make the sealing performance worse and worse. Solution: Install a pair of sealing rings inside the end seat bushing, one is fixed on the end seat bushing, and the other loading shaft rotates with the screw conveyor shaft. This can strengthen the seal of the conveyor and prevent the material from flowing out. Lengthen the size of the shaft sleeve at the sealing packing of the end seat, and enhance the sealing performance of the equipment by increasing the number of turns of the packing. Lubricate the contact surface between the shaft and the packing and the packing to enhance the sealing performance of the equipment.

Knowledge of use and maintenance of screw conveyor

Screw conveyor is a very versatile conveying equipment, which can convey powdery materials, granular materials, and small pieces of materials. Because the use environment of conveyors is mostly dusty environments, each movable part is easy to cover dust, so The equipment is frequently maintained. The loading conveyor must be started without load when starting the conveyor, and the feeding can only be carried out after starting. The feeding must be even, otherwise it will cause material accumulation, overloading of the drive device will reduce the service life of the equipment, and stop feeding before stopping. Stop the machine after the material in the case is completely exhausted. There should be no hard and large materials in the material, otherwise the screw will be stuck. During use, pay attention to check whether the fasteners are loose. If there is looseness, tighten it in time. When the screws between the screw connection shafts are loose, stop and deal with them immediately. The moving parts should be lubricated frequently. The oil in the reducer should be changed every 3-6 months, and the bearing boxes at both ends should be filled with lubricant every half month. , Every 3-5 months, remove the suspension bearing body together with the suspension shaft, remove the sealing ring, immerse the suspension bearing in the melted lubrication and cool it together with the grease, and reinstall it for use.
