Before using screw chain conveyors, we will study the relevant instructions and acquire some knowledge on their maintenance, as well as methods for addressing any difficulties or defects that may arise. In addition to being aware of such unexpected issues that may arise during operation, it is also important to pay attention to the maintenance tips and methods for screw chain conveyors in daily use, in order to extend their service life. Since the price of screw chain conveyor systems is much higher than that of ordinary conveying machinery, maintenance of such systems becomes particularly important. When maintaining a screw chain conveyor, it is not only necessary to take care of the hardware components; attention must also be paid to the maintenance of the software aspects. By software maintenance, what is meant is that operators must get rid of the bad habits and practices they employ when operating the equipment. First, the maintenance of the reducer box for the screw chain conveyor. Three months after the initial use of the screw chain conveyor, it is necessary to drain the oil from the engine’s gearbox, clean it thoroughly, and use diesel or automotive gasoline to clean the interior of the gearbox. After cleaning, new lubricant must be added up to the middle of the sight gauge immediately. It must be replaced every year thereafter, but it is important to note that too much lubricant can cause the gearbox to overheat, while excessive load on the motor can lead to the overload protector shutting down. Too little lubricant as well can cause the gearbox to overheat, resulting in increased noise. Subsequently, the maintenance of the drive chain of the screw chain conveyor is also essential. Excessive use of the drive chain can cause the original lubricant to heat up and evaporate, leading to common problems such as imbalance and excessive noise during operation. If faced with such a problem, it is possible to activate the linkage for the rudder, and use unsalted butter or a thicker lubricant. Another aspect is the maintenance and repair of the engines and transformers for screw chain conveyor systems. Water must not penetrate inside the motor, including any organic substances such as diesel or liquids that are used in the motor. If water gets in, it can damage the motor’s insulation layer, leading to malfunctions in the equipment. Shanghai Yuyin Machinery ultimately aims to establish operating standards for the personnel who actually operate spiral chain conveyor systems. It is essential to keep in mind the strict adherence to all safety procedures; actual operations must be carried out by trained staff or workers with experience, so that potential safety incidents can be addressed promptly and prevented in advance. To more effectively reduce the costs associated with the disassembly, maintenance, and repair of screw chain conveyor systems, it is essential to provide relevant training for the operators on the skills needed to operate and maintain such equipment.
