Simple self-analysis about slurry pump

The casting of each slurry pump can only be formed through extremely strict quality control. From the casting of slurry pumps, it can be roughly divided into two modes, lost foam casting and sand casting. The casting material is usually high chromium alloy or rubber. and other wear-resistant materials. In the casting process, it is necessary to control the casting temperature and cooling rate to ensure the quality and performance of the casting. At the same time, processes such as dimensional inspection and surface cleaning are also required to ensure the accuracy and appearance quality of the casting.

During this period, the Cr content of high chromium cast iron is also the only test item to verify the specific wear resistance of a product

Including the application composition of ductile iron and gray iron castings, the shape of iron molecules, and the best products must pass metallographic testing.

Every checkpoint in the process of design and casting and post-inspection process cannot be flawed

Design----manufacturing----core-making---core casting----casting heat treatment----machining----grinding----blank inspection----surface coating-- --assembly

A good core-making link will greatly reduce the roughness and defects of the cast product blank, the surface is smooth, the product structure is stable and wear-resistant, and the later heat treatment makes the product toughness, including wear resistance, hardness greatly improved, and the product quality is greatly improved. service life.

The machining of the precision lathe makes the product more accurate and more perfect, and the probability of leakage during product transportation is greatly reduced.

Post-processing blank inspection, grinding, surface anti-rust and anti-corrosion coating increase the service life of the pump body, making it difficult to replace the pump body after casting the foundation, and reducing the frequent downtime of the mine for maintenance
