Single-tube screw conveyor cement sealed manhole pipe-type screw conveyor, Daily maintenance management:During the use of the screw conveyor, it is essential to pay attention to daily maintenance to maximize coordination with the sand dryer, ensuring production capacity and efficiency, and also extending the service life of the equipment.(1)Lubricating oil should be regularly applied to transmission parts such as bearings, gears, and chains.(2)After the conveyor is shut down, check the wear of the screw blades; if severely worn, perform repair welding.(3)Do not overload the conveying capacity, as it may prevent material discharge, causing bending of the screw shaft and damage to the casing.(4)When conveying materials at high temperatures, ensure the casing expands and contracts freely without any obstruction; if issues arise, resolve them promptly.(5)If the conveyor emits harsh noise during operation, open the cover for inspection and troubleshoot the issue.

Application scope and characteristics: (1) The screw conveyor is widely used in chemical, building materials, grain, and other sectors as a conveying device, mainly for transporting powdered, granular, and small lump materials. It is not suitable for conveying perishable, sticky, or easily agglomerated materials. (2) The operating environment temperature for Naixin screw conveyors is -20°C to 50°C; the conveyor's inclination angle β ≤ 20°; the conveying length is generally less than 40m, with a maximum of 70m. (3) Compared to other conveying equipment, Cangzhou screw conveyors offer advantages such as simple structure, small cross-sectional dimensions, good sealing performance, the ability to load and unload at multiple points along the length, safe and convenient operation, and low manufacturing costs. Their drawbacks include severe wear of components, relatively low conveying capacity, high power consumption, and the tendency for materials to break during transportation.Single-tube screw conveyor cement sealed manhole pipe-type screw conveyor.
