Description
(54) ДВУХРОТОРНЫЙ ВАКУУМ-КОМПРЕССОР(54) DUAL TORCH VACUUM COMPRESSOR
1one
Изобретение относитс к области компрессоростроени .The invention relates to the field of compressor engineering.
Известны двухроторные вакуум-компрессоры , содержащие корпус с установленными в нем роторами первой и второй ступеней 1.Known two-rotor vacuum compressors, comprising a housing with rotors of the first and second stages 1 installed in it.
Известна конструкци вакуум-компрессора не позвол ет использовать его дл откачки паров криогенных жидкостей.The known construction of a vacuum compressor does not allow it to be used for pumping out vapors of cryogenic liquids.
Цель изобретени - повышение надежности при откачке паров криогенных жидкостей .The purpose of the invention is to increase reliability when pumping out vapors of cryogenic liquids.
Указанна цель достигаетс тем, что втора ступень выполнена в виде двух секций, а перва ступень размещена между последними и отделена от них вакуумируемыми камерами .This goal is achieved in that the second stage is made in the form of two sections, and the first stage is located between the latter and is separated from them by vacuumized chambers.
На чертеже изображен продольный разрез вакуум-компрессора.The drawing shows a longitudinal section of a vacuum compressor.
Вакуум-компрессор . содержит корпус 1 с установленными в нем роторами 2, 3 первой и второй ступеней. Втора ступень выполнена в виде двух секций 4, 5, а перва ступень 6 размещена между ними и отделена от них вакуумируемыми камерами 7. Роторы 2, 3 установлены в подщипниках 8, 9.Vacuum compressor. It includes a housing 1 with rotors 2, 3 of the first and second stages installed in it. The second stage is made in the form of two sections 4, 5, and the first stage 6 is placed between them and separated from them by vacuum-evacuated chambers 7. The rotors 2, 3 are installed in sub-supports 8, 9.
При откачке паров криогенных жидкостей температура их при сжатии в первой ступени повышаетс и во вторую ступень пары поступают с более высокой температурой , что вместе с вакуумируемыми камерами 7 обеспечивает нормальную работоспособность подшипников 8,,9, что обеспечивает повышение надежности работы вакуум-компрессора при откачке паров криогенных жидкостей .When pumping out vapors of cryogenic liquids, their temperature during compression in the first stage rises and the second stage comes with a higher temperature, which, together with evacuated chambers 7, ensures normal operation of the bearings 8, 9, which improves the reliability of the vacuum compressor when pumping vapor cryogenic liquids.
