As the core component of the hydraulic end of the plunger pump, the emulsion pump head body bears great pressure. Therefore, the finite element analysis of the pump head body is of great significance to improve the reliability and rationality of product design. Due to the particularity of the pump head body structure, researching its processing technology and improving processing efficiency are the keys to reducing production costs and improving product competitiveness. The movement law of the plunger pump, the pulsating flow 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 provides a theoretical basis for the analysis of the pump head body. The stress state provides an important theoretical basis.
Using the analysis of the stress distribution law and fatigue life distribution state of the emulsion pump head body under the maximum stress condition, the improvement measures of the pump head structure are proposed according to the analysis results. According to the working conditions and structural characteristics of the pump head body, the process route of the pump head body from material, blank, large-diameter hole nesting, turning step hole, milling inch thread, rolling to hydraulic self-enhancement is given. The characteristics of the nesting drill, the structure type of workpiece rotation and external chip removal is selected, and the related technology of the nesting drill is analyzed in detail, such as cutting power, the selection of cutting amount, cooling and chip removal, and the nesting drill is different from ordinary holes. Auxiliary devices for processing equipment.
Tool parameters are an important factor affecting the machining efficiency and service life of the tool. Since the nesting drill works in a confined space, while satisfying the machining efficiency, the determination of chip breaking and chip removal is the key to the design of the nesting drill. The influence of the tool axial vibration on the cutting angle during the hole process is analyzed, and the theoretical basis for the influence factors of the hole axis deflection is given. The inch thread is processed by milling, and the application of macro program improves the efficiency of thread milling. In order to increase the strength and service life of the pump head body, the inner cavity is prestressed by the hydraulic self-enhancing method of the inner hole.Yuyao Shinri Sprayer Co., Ltd. is leading China ODM mist sprayer pumps manufacturers, has 16000 square meters of scale, including 10000 square meters of Nozzle Factory (YSR: Yuyao Shinri Sprayer Co.
