Implementing of a DC-Motor Model into a Simulation Tool for Diaphragm Pumps
DC-Motors are commonly used in diaphragm pumps. Understanding the dynamics of the drive-pump system and modelling of such a system is the key task of this project.
Keywords: - Strong interests in mechanics (dynamics)
- Interest in modelling and programming (Matlab)
- Interest in experimental work
- Self-initiated way of working
DC-motors together with an eccentric and a connecting rod are commonly used to drive the working diaphragm of liquid diaphragm pumps. The torque which the motor has to provide and the force which acts on the ball bearing between the eccentric and the connecting rod depend on the pressure in the working chamber and the position of the eccentric. These quantities are essential for the layout of the DC-motors and the ball bearings. Furthermore the moment of inertia of the eccentric and the whole drive mechanism causes vibration in the pump, which we try to understand.

This project will be realized in cooperation with KNF Flodos, a global supplier of liquid diaphragm pumps. The main goal is the implementation of a drive model (angular momentum principle) into an existing simulation environment (Matlab) for the hydraulic network of the pump. Measurements of torque and force which are acting on the motor or the bearing can be conducted at KNF in Sursee. Analysing, interpretation and reporting the simulation and measurement results are the final steps of this project.
