As the core part of the Plastic Pump(KEXON) hydraulic end, the emulsion pump body bears great pressure. Therefore, the finite element analysis of the pump body is of great significance for improving the reliability and rationality of the product design. Because of the particularity of pump head structure, the key to reduce production costs and improve product competitiveness is to study its processing technology and improve processing efficiency. The motion law, fluctuating flow rate and pressure fluctuation caused by fluctuating flow rate of Lotion Pumps are analyzed, and the relevant factors causing pressure fluctuation are obtained, which provides theoretical basis for the design and improvement of plunger pump, as well as an important theoretical basis for the analysis of the stress state of the pump head.
The stress distribution rule and the fatigue life distribution state of the emulsion pump head under the maximum stress condition are analyzed, and the improvement measures of the pump head structure are put forward based on the analysis results. According to the working conditions and structural characteristics of the pump head body, the technological routes of the pump head body from a material, blank, large diameter hole sleeve processing, turning step hole, milling English thread, rolling to hydraulic self-strengthening are given. The characteristics of the sleeve drill are emphatically analyzed. The structure types of workpiece rotation and chip discharge are selected, and the drilling technology related to the sleeve drilling, such as cutting power and cutting parameters, are analyzed in detail. Selection, cooling and chip removal, and socket drilling are different from the auxiliary devices of common hole processing equipment.
