Description
Изобретение относитс к компрессоре строению и может быть использовано в винтовых холодильных компрессорал с регулируемой производительностьюThe invention relates to a compressor structure and can be used in screw refrigeration compressor with adjustable performance.
Цель изобретени - повышение надежности и долговечностиThe purpose of the invention is to increase reliability and durability.
На чертеже изображена схема винтового компрессорного агрегата.The drawing shows a diagram of a screw compressor unit.
Винтовой компрессорный агрегат содержит корпус 1 с размещенными в нем взаимодействующими роторами 2. На конце вала каждого ротора 2 закреплен поршень 3, расположенный в разгрузочной камере 4 корпуса 1. В расточке корпуса 1 расположен золотниковый регул тор 5 производительности с приводным штоком 6 и дополнительным штоком 7. К разгрузочной камере 4 подсоединена лини 8 разгрузки с маслонз- сосом 9 и регулируемым дросселем 10 Ci толкателем 11. Дроссель 10 установлен сThe screw compressor unit includes a housing 1 with interacting rotors 2 placed at it. At the end of the shaft of each rotor 2, a piston 3 is fixed, located in the discharge chamber 4 of housing 1. In the bore of the housing 1 there is a spool capacity regulator 5 with a drive rod 6 and an additional stem 7 A discharge line 8 is connected to the unloading chamber 4 with an oil tank 9 and an adjustable 10 Ci throttle pusher 11. The throttle 10 is installed with
возможностью взаимодействи толкател 11 с дополнительным штоком 7 регул тора 5 и расположен после маслонасоса 9.the possibility of interaction of the pusher 11 with the additional stem 7 of the regulator 5 and is located after the oil pump 9.
Винтовой компрессорный агрегат работает следующим образом.Screw compressor unit works as follows.
Вращение роторов 2 приводит к всасыванию , сжатию и нагнетанию газа в компрессоре При уменьшении производительности компрессора регул тор 5 перемещаетс вправо. Осевое усилие на роторах 2 от газовых сил при этом уменьшаетс . Дополнитель ный шток 7 соприкасаетс с толкателем 11 и перемещает его вправо, уменьша проходное сечение дроссел 10. Давление в линии 8 и разгрузочной камере 4 уменьшаетс , уменьша усилие разгрузки роторов 2. При увеличении производительностиThe rotation of the rotors 2 leads to suction, compression and gas injection in the compressor. When the compressor capacity decreases, the regulator 5 moves to the right. The axial force on the rotors 2 is reduced by gas forces. The additional rod 7 contacts the pusher 11 and moves it to the right, reducing the throttle flow area 10. The pressure in the line 8 and the discharge chamber 4 decreases, reducing the unloading force of the rotors 2. As the output increases
компрессора регул тор 5 перемещаетс влево. Осевое усилие на роторах 2 от газовых сил при этом увеличиваетс . Шток 7compressor 5 adjusts to the left. The axial force on the rotors 2 from the gas forces increases. Stock 7

перемещаетс влево. Толкатель 11 под действием пружины возврата также перемещаетс влево за штоком 7, увеличива проходное сечение дроссел 10. Давление в камере А увеличиваетс , увеличива усилие разгрузки роторов 2.moves to the left. The pusher 11 under the action of the return spring also moves to the left behind the rod 7, increasing the flow area of the throttles 10. The pressure in chamber A increases, increasing the unloading force of the rotors 2.
Таким образом, при регулировании производительности винтового компрессора усилие разгрузки роторов 2 всегда соответствует усилию от газовых сил, что позвол ет разгрузить опоры роторов, повысить их долговечность. Снижение усилий на опорах повышает надежность винтового компрессора.Thus, when adjusting the performance of a screw compressor, the unloading force of the rotors 2 always corresponds to the force from the gas forces, which makes it possible to unload the rotor bearings and increase their durability. Reducing the effort on the supports increases the reliability of the screw compressor.
