The Plastic Pump (KEXON) head body is the core component of the hydraulic end of the plunger pump, under great pressure, Therefore, the finite element analysis of the pump head body is of great significance for improving the reliability and rationality of the product design. Due to the particularity of the pump head structure, researching its processing technology and improving processing efficiency are the key to reducing production costs and improving product competitiveness. The movement law of the plunger pump, the pulsating flow rate and the pressure fluctuation caused by the pulsating flow are analyzed, and the relevant factors causing the pressure fluctuation are obtained, which provides a theoretical basis for the design and improvement of the plunger pump, and also analyzes the pump head body. The stress state provides an important theoretical basis.

The stress distribution law and the distribution of fatigue life of the plastic pump head under the maximum stress condition are analyzed, and the improvement measures of the pump head structure are proposed based on the analysis results. According to the working condition and structural characteristics of the pump head body, the process route of the pump head body from the material, blank, large-diameter hole-nesting, stepped hole, milling inch thread, rolling to hydraulic self-enhancement is given. The characteristics of the nesting drill, the structure type of the workpiece rotation and the external chip removal are selected, and the related processes of the casing drilling and drilling are analyzed in detail, such as the cutting power, the selection of the cutting amount, the cooling and chip removal, and the nesting drill different from the ordinary hole. Auxiliary device for processing equipment.
