Item Trouble free use and stabilization of pipeline systems(Sumy State University, 2014) Kuguk, V.A.; Ткачук, Юрій Якович; Ткачук, Юрий Яковлевич; Tkachuk, Yurii YakovychThe control of fluid dynamics is essential to ensure efficient, reliable and safe operation of pumping systems. A pump puts fluid in motion by adding energy to it. This kinetic energy, observed as pressure, is carried in the fluid and slowly lost to friction in the piping system. Uncontrolled fluid in motion can physically destroy the pump, piping, valves, meters and other system components.Item Graphic-analytical method of defining pressure characteristics of centrifugal-vortex pumps(Sumy State University, 2014) Ткачук, Юрій Якович; Ткачук, Юрий Яковлевич; Tkachuk, Yurii Yakovych; Найда, Максим Васильович; Найда, Максим Васильевич; Naida, Maksym VasylovychCentrifugal-vortex pumps are usually adopted for a small boiler feeding of a hot-water heating system and also in the water-supply system, in the food and oil industry. Centrifugal-vortex pumps have rather good operating showings in the results of successful using of the positive qualities if the centrifugal working wheel and vortex one. They are fixed on the common shaft.Item Antiturbulence influence of small fractions soluble gas in liquid(Сумський державний університет, 2013) Ткачук, Юрій Якович; Ткачук, Юрий Яковлевич; Tkachuk, Yurii Yakovych; Naida, M.V.One of the most famous ways of increasing the oil pipe-line capacity and extension of common pipe-effective pipe-lining transport is usage of antiturbulence additive (ATA). ATA – antiturbulence additive – a reagent for the reduction of hydraulic resistance are some materials that are soluble in the following liquid, reducting stipulated with friction of loss pressure when liquid flows in channel or pipe-line.
