Lubrication Analysis Of Driving System And Alternate Material In Diaphragm Pump

Reciprocating piston pump and diaphragm pump is a rugged pressure pumps, etc., to overcome the pump seal wear and other shortcomings developed an ideal reciprocating feed pump. It is simple, efficient and reliable transmission can be high temperature, high-abrasive materials and solid-liquid two-phase media of high viscosity of the fluid delivery of long-distance high-lift. The thesis of "different oils on ZA303zinc-based alloys and aluminum bronze wear analysis of two materials slide rod bearing and replace" as the main research around the "skateboard, lubricating guides and materials substitution, and diaphragm force terminal size reduction "as the desired effect, a more comprehensive analysis of key components of the diaphragm.The first analysis of the diaphragm structure, the use of Pro/E software for three-dimensional modeling in the analysis of the diaphragm movement mechanism and the force law, based on the established mathematical model of slider-crank mechanism, the use of MATLAB software to solve kinematics dynamics equation. Second, the use of mechanical system dynamics simulation software ADAMS build virtual prototypes, and analyze the movement of the prototype and the force, and comparing the established mathematical model validation, using the kinematic analysis of the data speed to provide a basis for the trial, the use of analysis of kinetic data to provide for the finite element load basis.By ANSYS finite element software for skateboards and guide the contact stress analysis to determine the maximum contact stress for the wear test to provide load data. Explore the use of preliminary calculations for the crankshaft bearing with the possibility of rolling, and the strength of linkage analysis.Finally, according to previous experimental results of the analysis as the basis of load factors than the variable pressure experimental study to simulate normal operating conditions using different factors for long-wear lubricant for the experimental study to simulate the machine off the oil for the lubrication of different factors agent under the lack of oil wear experiments.
