Cyclic deformation of separating tape in electromagnetic rolling pump

Abstract

Abstract The purpose of the paper is to justify a substantiation of the possibilities of trouble-free operation of de-axial pump based on the Rolamite mechanism with rolling bodies. The use of an electromagnet as a drive makes it possible to transfer the rotation into a closed space as well as abandon bearings and seals. The flexible tape allows reducing the slip friction and getting separate cameras with the possibilities to pump two substances at a time. The structure of the strain cycle of combined stretching and bending during rotation is investigated in details for the separating tape. The thickness of the tape which provides the specified durability of operation is determined.
