Автомат реверсу для поршневих насосів із гідроприводом

Abstract

The known structural performances of pumps and their drives are analyzed. The efficiency of application of pumps with the hydraulic drive that is controlled by means of hydraulic automaton of reverse – self-vibrating two-way sliding valve is justified. The analysis of approaches to creation of bases of analytical calculation of piston pumps - converters with drive, which showed the actuality of the development of adequate mathematical model of pump, that allow to carry out researches and calculations in the general formulation is carried out. The mathematical model of work of hydraulic drive of pumping unit is offered and its experimental verification is carried out. The model gives possibility of choice of rational parameters and performances which will provide the optimum modes of liquids’ pumping.
