Petrus' V. Hydraulic impulsive drive of membrane pumping unit for high-viscosity, corrosive and abrasive-carrying mediums pumping

Object of research - processes taking place in а impulsive drive and membrane pumping unit. Subject of research - hydraulic impulsive drive of membrane pumping unit for high-viscosity, corrosive and abrasive-carrying mediums pumping. Aim of research - making of a hydraulic impulsive drive of membrane pumping unit for high-viscosity, corrosive and abrasive-carrying mediums pumping with maximum productivity and head of the pumping unit having high overall efficiency. For analysis and solving of assigned tasks such research methods are used: method of mathematical modeling with the use of mechanics of solid laws, hydraulic drive theory and hydroautomatics theory, theory of the systems modeling and analysis; numerical methods of the systems of linear and nonlinear differential equalizations decision; method of fuzzy sets; methods of mathematical statistics and regressive analysis. A scientific novelty is that: first a mathematical model of working process of membrane pumping unit hydraulic impulsive drive is developed for defining of rational design parameters of a pumping unit and combined automatic hydrodistributor as like as drive hydrosystem capabilities; new regressive dependences are got for defining of hydraulic impulsive drive and membrane pumping unit optimal constructive and working parameters; the admissible speed value of pump executive device is set during time of suction, that allows to provide noncavitation work of pump; the mathematical model on the basis of fuzzy logic for membrane hydraulically driven pumps diagnosis is developed; working parameters, capabilities and optimal operating conditions of the hydraulic impulsive drive with combined automatic distributor and membrane pumping unit which is driven by this drive are scientifically based. A practical value consists in development of hydraulic impulsive drive of membrane pumping unit which allows to provide the set law of motion of membrane pumping unit working organ and smooth change of its initial parameters and operating capabilities; in development of design procedure and recommendations relative to the choice of rational operating parameters and exploitation modes of hydraulic impulsive drives of membrane pumping units. Degree of introduction - introduced in military department A2783, OC "Vinnyfruit" and PEF "Kastor" and also introduced in educational process of Vinnytsia National Technical University. Sphere (industry) of the use - in subsections of Ministry of emergency measures, manufacturing environments of heat power engineering, oil, chemical and food industry.
