Emulsion Pump Hydraulic Part Dynamic Analysis And Structural Optimization

Coal mining mechanization, especially the mechanized technology widely used, requires coal mining emulsion pump can provide higher pressure and flow rate. In order to meet the production requirements, need to design out more excellent emulsion pump. Following to the traditional design method, only using the experience design method and experimental method, change the parameters or conditions of pump is difficult, and it is difficult to improve performance, and to parametric design.In this paper, the method of using software modeling and simulation to design before production is used in analysis and adjustment, in order to achieve the purpose of improving and optimizing parameter and structure of the pump. Through the application of computer simulation for dynamic simulation and optimization design method, provides a new way of thinking to solve practical design problems. Using the simulation software to design is easy to change the parameters, and easy to realize the parametric design, and be with the objective conditions good consistency. So, using the software to simulate comes to be a trend in the optimization of the design and quality control.In this paper Author combine traditional design and simulation in structure and system to generalize a series of method of emulsion pump dynamic characteristics analysis and optimization design. System simulation model is established by AMEsim, analyze the relationship between intake and exhaust valve work in progress and design parameters, analyze motion curve of the dynamic motion of the suction drain valve. Analyze the relationship of the inlet valve open retarded angle, volumetric efficiency and to the valve parameters derived the relationship between the parameters of the spring and open the retarded angle and a volumetric efficiency. Author use three-dimensional modeling method to establish the contact stress analysis of the situation suction valve, checking the strength of the suction valve.To further study the impact of the force of the valve and fluid valve seat valve plate, as the research object to the conical valve cone valve gap model in FLUENT, and its flow field simulation. Explore the impact of poppet valve apex angle and service life of the valve. Draw a conclusion the impact of cone the valve apex angle to valve life on and off sealing. Though study the plunger reciprocates pressures and changes, the relationship between the pressure change with the crank angle of rotation is obtained. Draw the parameters of the maximum pressure point pressure and crank angle, and provides a guideline for the plunger checking and optimization.
