The PV2R series vane pump is a type of hydraulic pump widely used in industrial machinery, construction equipment, and mobile hydraulics due to its reliable performance and adjustable displacement. Its manufacturing process involves material selection, precision machining, assembly, and testing to ensure efficiency and durability.

Material Selection and Component Preparation

The production begins with selecting high-quality metals, typically alloy steel or cast iron, for components such as the rotor, vanes, and housing. These materials provide strength, wear resistance, and corrosion resistance. Raw materials are inspected and prepared through cutting, casting, or forging processes to achieve the initial shape and size required for machining.

Precision Machining

Critical components of the PV2R vane pump, including the rotor, cam ring, and vanes, are machined with high precision. CNC machines, grinders, and lathes are used to achieve tight tolerances and smooth surfaces. Accurate machining ensures the pump operates efficiently, maintains consistent pressure, and minimizes internal leakage.

Assembly and Component Fitting

After machining, the components are cleaned, inspected, and assembled. The rotor is fitted with vanes, and the cam ring and end plates are positioned in the housing. Proper alignment and fit are crucial to ensure smooth rotation and consistent hydraulic performance. Lubrication may be applied during assembly to reduce initial friction and wear.

Testing and Quality Control

Once assembled, the PV2R vane pump undergoes rigorous testing. Performance parameters such as flow rate, pressure, efficiency, and noise level are measured to confirm compliance with design specifications. Any deviations are addressed, and pumps passing all tests proceed to final finishing, labeling, and packaging.
