Description
(54) ВИНТОВОЙ КОМПРЕССОР(54) SCREW COMPRESSOR
1one
Изобретение относитс к энергетическому машиностроению, в частности к винтовым компрессорам.The invention relates to power engineering, in particular to screw compressors.
Известен винтовой компрессор, содержащий корпус, всасывающие и нагнетательные патрубки, установленные на опорах и вход щие в зацепление между собой роторы, каждый из которых состоит из двух участков с одинаковым профилем зубьев, сопр женных между собой по торцовым поверхност м 1 .A screw compressor is known, comprising a housing, suction and discharge nozzles, mounted on supports and interlocking rotors, each of which consists of two sections with the same tooth profile that are coupled to each other along face surfaces 1.
Недостатком его вл етс неорганизованный процесс всасывани газа, что вызывает ухудшение энергетических показателей компрессора. Плоха обтекаемость зубьев винтов на входе в полости и отсутствие необходимой направленности потока газа вызывает удары и завихрени , повышенные потери.Its disadvantage is an unorganized gas suction process, which causes a deterioration in the energy performance of the compressor. Poor streamlining of the teeth of the screws at the entrance to the cavity and the lack of the necessary directionality of the gas flow causes shocks and turbulence, increased losses.
Цель изобретени - уменьшение потерь на входе.The purpose of the invention is to reduce losses at the entrance.
Указанна цель достигаетс тем, что участок каждого ротора, расположенный со стороны всасывающего патрубка, выполнен пр мозубым .This goal is achieved by the fact that the section of each rotor, located on the side of the suction nozzle, is made straight.
Кроме того, отношение длины пр мозубого участка каждого ротора к общей длинеIn addition, the ratio of the length of the bore section of each rotor to the total length
нарезной части каждого ротора составл ет не более 1:3.The rifled portion of each rotor is no more than 1: 3.
На фиг. 1 изображен компрессор, продольный разрез; jpa фиг. 2 - винты, поперечное сечение; на фиг. 3 - ротор, разрез.FIG. 1 shows a compressor, a longitudinal section; jpa of FIG. 2 - screws, cross section; in fig. 3 - rotor, cut.
Винтовой компрессор состоит из корпуса I, всасывающего 2 и нагнетательного 3 патрубков, установленных на опорах 4 и вход щих в зацепление между собой ведущего 5 и ведомого 6 роторов, каждый из которых состоит из участков 7-9 с одинаковым профилем зубьев, сопр женных между собой по торцовым поверхност м 10, причем участок 7 каждого ротора 5 и 6, расположенный со стороны всасывающего патрубка 2, выполнен пр мозубым.A screw compressor consists of a case I, a suction 2 and an injection 3 nozzles installed on supports 4 and the driving 5 and the follower 6 rotors intermeshing among themselves, each of which consists of sections 7–9 with the same tooth profile that are interconnected on the face surfaces 10, wherein the section 7 of each rotor 5 and 6, located on the side of the suction nozzle 2, is made annular.
Отношение длины t пр мозубого участка 7 к общей длине L нарезной части каждого ротора 5 и 6 составл ет не более 1 :3. Угол от начала сжати до замыкани линии зацеплени обозначен через щ.The ratio of the length t of the annulus 7 to the total length L of the threaded part of each rotor 5 and 6 is not more than 1: 3. The angle from the beginning of compression to the closure of the line of engagement is denoted by u.
