The process of water pump processing

Preparation of raw materials: The structure of water pump parts is complex, with castings accounting for over 80%, mainly consisting of cast iron, cast steel, and cast stainless steel parts; There are few shaft components, mainly high-quality carbon steel, chromium steel or stainless steel parts. Select the appropriate blank manufacturing process based on the shape and material characteristics of the parts, such as casting, forging, or welding.
Mechanical processing: Turning, milling, drilling and other mechanical processing of the blank to form the basic shape and size of the water pump. During the processing, it is necessary to strictly control the dimensional accuracy and surface roughness to ensure the quality of the parts.
Heat treatment: Heat treatment is carried out on key parts, such as carburizing, quenching, etc., to improve the hardness, wear resistance, and corrosion resistance of the parts.
Cleaning and rust prevention: Clean the oil stains, iron filings and other impurities on the surface of the parts, apply rust prevention oil to prevent rusting of the parts.
Assembly: Assemble the processed qualified parts according to the design requirements to form a complete water pump product. During the assembly process, it is necessary to ensure the precision of the fit and sealing between the parts.
