Core Summary of Overall Quality Control

Closed-loop Control

Factory Appearance Protection Control

Performance Verification Control

Core Assembly Control

Incoming Raw Material Quality Control

The material of core wear parts and pressure-bearing components directly determines the service life of slurry pumps. Raw material quality control eliminates unqualified materials and material mixing issues, serving as the foundation of overall product quality.

Casting Blank Quality Control (Core Wear Parts Control)

Core flow components of slurry pumps such as impellers, pump bodies, front guard plates, rear guard plates and protective sleeves are all castings. Defects in casting blanks are the main causes of rapid wear, cracking and leakage during operation. Strict control shall be implemented throughout the casting process and blank inspection.

Machining Quality Control (Precision Control)

Machining determines the fitting precision, coaxiality and sealing performance of components, which is the key link to ensure stable operation, low vibration and zero leakage of slurry pumps. All machined parts undergo self-inspection, patrol inspection and final inspection during processing.

Heat Treatment Quality Control (Performance Enhancement Control)

Wear parts and stressed parts of slurry pumps require heat treatment to improve hardness, wear resistance and impact resistance. Improper heat treatment will cause component brittleness, insufficient hardness and shortened service life. Process parameters must be strictly controlled.

Pre-assembly Control

Component screening and cleaning before assembly are critical to avoid assembly impurities, jamming and wear. Early pump wear and seal damage are mostly caused by assembly impurities.
