Pe Tubes Factory introduced that the emulsion pump head body, as the core component of the hydraulic end of the plunger pump, 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.

The stress distribution law and fatigue life distribution state of the emulsion pump head body under the maximum stress condition are analyzed, and 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 stepped holes, milling inch threads, rolling to hydraulic self-enhancement is given. The characteristics of the nesting drill, selecting the structure type of workpiece rotation and external chip removal, and analyzing the related drilling process of the nesting drill in detail, such as cutting power, selection of cutting amount, cooling and chip removal, and the difference between the nesting drill and 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 processing is carried out by means of milling, and the application of macro programs 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.

Through the above introduction, Mist Pump Factory hopes that you can simply refer to the content of this article in future use.
