How To Maintain The Impeller When Using The Slurry Pump To Reduce Wear?

The use of slurry pumps is becoming more and more widespread, and inevitably, accessories usually wear during operation, and are often used to improve the internal flow state of the pump, improve the wear resistance of the runner material, and improve the surface finish of the runner to reduce wear.According to tribological classification, wear belongs to two body wear, namely, corrosive hard solid particles and the surface of the runner component constitute friction.Their respective characteristics and contact surfaces determine the type and degree of wear of the runner component. Therefore, the main factors that cause wear of the accessories impeller can be summarized as follows.　　1. Properties of solids in slag and slag.2. The movement characteristics of the solid and liquid phases in the pump, that is, the contact between the solid and liquid phase and the liquid phase and the surface of the flow path component.3. Material characteristics of the pump's runner component.In order to maintain good working efficiency of the slurry pump, this is closely related to the maintenance of accessories. So what should we pay attention to in processing?1. When rotating the impeller, the gap between the machine tool, tool holder and tool holder should be adjusted to the smallest position as possible to ensure that the entire machine tool processing system has sufficient rigidity.The chamfer of the workpiece should be as large as possible so that the turning tip can be cut in and out smoothly during the turning process, thereby minimizing the impact on the tool tip and the cracks in the workpiece as much as possible.2. A reasonable cutting tool geometric angle is conducive to improving the durability of the slurry pump.The grinding wheel should be stable and sharp during grinding, and the saw blade should be ground into a straight line without sawing teeth.
