Information × Registration Number 0214U006941, 0111U002407 , R & D reports Title Engineering of highly power rare magnets producing technology and development at this base of physics-technical principles of creation of magnetically-mechanical constructions with improved power characteristics for catchers of ferromagnetic wreckages in wells, magnetic springs and other devices. popup.stage_title Head Milman Yulii Viktorovich, Доктор фізико-математичних наук Registration Date 10-04-2014 Organization Frantzevich Insitute for Materials Science Problems of the Ukranian National Academy of Sciences popup.description2 Four fundamentally new constructions of well magnetic grab (WMG) were elaborated for cleaning and emergency renewal of oil and gas wells in a to 4000-5000 m depth from ferromagnetic wreckages. The full-scale WMG were made. The tearing effort of 857.3 kG was achieved at the full-scale WMG with diameter 100 mm witch exceed the analogues. The constructions of WMG with adjusting magnetic-field were elaborated, that allows to prevent sealing of device in the column of oil-well. The fundamentally new constructions of two types magnetic springs were elaborated, equalizations for determination of force of involvement were worked out. Magnetic springs are used in a reverse valves in oil-wells, in stepping motors and door closers.
