[Abstract]:Diaphragm pump is based on reciprocating piston pump at the end of 1970s, which is evolved by adding diaphragm chamber to realize the separation between piston and transport medium, thus creating a new advanced transportation equipment and technology. It not only has the advantages of strong and durable piston pump, large transportation flow rate and high conveying pressure, but also has the advantages of high temperature resistance, high corrosion resistance, convenient maintenance, long life of easily damaged parts, low operating cost and high continuous operation efficiency. High-efficiency, energy-saving, environmental protection and many other new advantages and new features. In this paper, "diaphragm pump crankshaft bearing replacement" as the main research content, "connecting rod big end and small end bearing and crankshaft main bearing from rolling bearing to plain bearing" as the expected effect. The bearing capacity of diaphragm pump crankshaft bearing is analyzed comprehensively. In this paper, the working principle and structural characteristics of diaphragm pump are analyzed firstly, and the mathematical model of crank and slider mechanism is established, and the kinematics and dynamics equations are solved by MATLAB software, and the three dimensional model of diaphragm pump transmission system is built by means of Pro-e software. On the basis of analyzing the motion mechanism and force law of diaphragm pump, a virtual prototype is constructed by using the mechanical system dynamics simulation software Adams, and the kinematics and dynamics parameters of diaphragm pump drive system are determined by prototype simulation. Compared with the established mathematical model, the data are used to provide the load basis for the finite element calculation. The static analysis of crankshaft under rolling bearing condition is carried out by HyperMesh and Workbench finite element software, and the stress and deformation law of crankshaft under single and multiple crank are determined, and the position of crankshaft under maximum stress and strain is determined. The contact analysis of the crankshaft and the sliding bearing is carried out at this position to determine the stress strain and contact stress of the crankshaft. At last, the static analysis of the connecting rod is carried out, and the optimum design is carried out.
