Influence of leakage on characteristics of the vacuum transport unit based on the water-ring pump
Vladimir Naumov
Abstract
Abstract The mathematical model of the liquid pumping process using the autonomous vacuum transport unit based on the water-ring pump is proposed. Such units are used, in particular, for pumping aggressive liquids. The performance characteristics of ERSTVAK’s ELRS-2 water-ring vacuum pump were used in the calculation. The system of differential equations was solved numerically. An increase in the leakage coefficient leads to a raising the absolute pressure in the tank at the end of the first stage. As a result, the volume of liquid pumped in one cycle is noticeably reduced. Therefore, the average performance and efficiency of the unit is significantly reduced. The duration of one cycle changes slightly
