Experimental study of a vacuum fluid transportation system

The authors proposed a method of calculation the main parameters of a vacuum fluid transportation system. In this paper a designed experimental stand for verification of the proposed method was proposed. Selection of the required equipment including vacuum pumps, differential pressure sensors and control valves was made. The body and covers of the pumped vacuum chamber were made using additive manufacturing techniques. A subsequent identification of the selected vacuum pumps' characteristics was carried out taking into account the conductivity of the connecting pipelines. The pressure difference established in the chamber was calculated taking into account the relationship between the pumping speed and the pressure obtained during the experiment. As a result of the experiment, the pressure values in the mechanical and hydraulic compartments of the chamber, the volume of liquid pumped by the vacuum system were obtained.
