In the master’s thesis engineering simulations are applied to investigate the contact conditions in the pump during its operation. By setting up a contact simulation, we try to realistically estimate the locations and magnitudes of contact loads in the pump gearing and other sliding surfaces. The analysis is performed with the finite element method. We set up three simulations that differ in terms of time dependence and type of load. The first simulation is quasi-static with integrated loads. In the second simulation, the rotation of pumping elements with integrated loads is introduced. In the third simulation, the pump parts are exposed to the conditions resulting from the flow simulations on this pump. The results of the simulations show that the highest contact pressures occur on the 3D-gearing, the lower edge of the plain bearing and on the lines in the design connection. The contact locations in the simulations coincide well with the actual wear locations of the pump parts.
