Description

II

Изобретение относитс  ;с гакз.т чомз и компрессорному машиностроешю.The invention relates to a chamze.t chomz and a compressor machine tool.

Известен способ работы жиг1костнокольцевой машины путем введени  в рпбочуто жидкость присадок с малым упельньгм весом и о азовани  пленки на поверхности колыю l ,There is a known method of operating a ganglone-ring machine by introducing a liquid with additives with a low actual weight and introducing a film on the surface of the cola into the liquid.

Однако в известном способе работы при откачке паров криогенных жиакостей происходит подогрев их на всасывании и снижение КПД за счет весогюй производительности.However, in a known way of working when pumping out vapors of cryogenic fluids, they are heated by suction and the efficiency is reduced due to the high productivity.

Цель изобретени  - повьаиение КПД при откачке паров криогенных жидкостей.The purpose of the invention is to improve the efficiency when pumping out vapors of cryogenic liquids.

Это достигаетс  тем, что в качестве присадок используют порошковые теплоизолирующие материалы, например вспученный перлитовый песок.This is achieved by using heat insulating materials, for example expanded perlite sand, as additives.

На чертеже схематически изображена жидкостно-капьиева  машина дл  реализа1ШИ предложенного способа, продольнь й разрез.The drawing shows schematically a liquid-capia machine for realizing the proposed method, a longitudinal section.

Машина содержит корпус I с эксцентрично устаноЕэтв ным в нем ротором 2,The machine includes a housing I with an eccentric rotor 2 installed in it,

Ek) всасывающей полости 3 размещен трубопровод 4 дл  подачи присадок и образовани  пленки 5 на поверхность кать- да G.Ek) to the suction cavity 3 a conduit 4 is placed for supplying the additives and forming a film 5 on the surface of the cathode G.

При откачке паров криоген1гых жидкостей пленка 5 из теплоизолирующего материала уменынает теплообмен между всасываемым гааом во всасьшаюитей полости 3 и жидксстньа кольцом 6, что no№imaет КПД за счет увеличени  весовой производительности .When pumping out the vapors of cryogenic liquids, the film 5 from the heat insulating material decreases the heat exchange between the inhaled gas in the intake of cavity 3 and the liquid ring 6, which noo means efficiency due to an increase in weight performance.
