New improved seal designs of centrifugal machines and techniques their numeral and analytical calculation can be used by pump and compressor engineering companies at development of new and modernization of existing designs of centrifugal machines, that is used in gas-oil industry, thermal and atomic energy, rocket-space technology for increasing of their reliability, economy and ecological safety.5481 Product Description popup.authors Гудков Сергій Миколайович Дейнека Андрій Віталійович Загорулько Андрій Васильович Міщенко Светлана Олексіївна Орел Ольга Валентинівна Пилипенко Віктор Валерійович Савченко Євген Миколайович Терновський Сергій Анатолійович Халізева Альона Генадіївна popup.nrat_date 2020-04-02 Close
