Screw conveyor safe operation, easy maintenance, and screw conveyor can be sustained and stable delivery of materials. Screw conveyor, due to its length, the screw conveyor screw axis deflection very prone to screw conveyor screw axis bending phenomenon. The screw conveyor is used at both ends of the bearing support structure, prone to the use of the screw conveyor, screw conveyor blades and housing, screw conveyor bearings and screw conveyor end seal wear and tear, so the screw conveyor on the manufacture of the screw conveyor shaft and screw conveyor side of the gap is relatively large. 
 However, due to the screw conveyor shaft seal and the screw conveyor-side seat at the gap is relatively large, so the sealing effect of the screw conveyor is relatively poor, and with the tightness of the time the growth of the screw conveyor screw conveyor use is getting worse. Therefore, we need to improve the sealing system of the screw conveyor. 

 1, the shaft and screw conveyor screw conveyor's side seat sleeve the inside of the installation of a pair of seal ring, a fixed end sleeve on the screw conveyor, and the other loading screw conveyor shaft rotation . This improved the tightness of the screw conveyor to prevent the outflow of material from the screw conveyor. 

 2, longer screw conveyor end seal the size of the filler at the sleeve, through the enhancement of the number of turns of the screw conveyor packing to enhance the tightness of the screw conveyor. 

 Lubricating, and enhance the tightness of the screw conveyor, screw conveyor shaft contact surfaces and screw conveyor with packing packing.
