【 摘 要 】

The design of a vacuum pumping system based on the principle of the displacement membrane was proposed. This principle does not imply contact of the working metal surfaces with the transported liquid. This article presents a calculation method of the main parameters of the proposed vacuum fluid transportation system. As a result of the calculation, the values of the pumping speed, the dimensions of the displacement membrane, the required chamber height, the pressure drop in the chamber, required to ensure the deflection of the displacement membrane, were obtained. Based on the proposed method, a program for calculation the main parameters of a liquid transfer system based on the mathematical software MathCAD was developed.
