Description

(54) РОТОР ВИНТОВОЙ КОМПРЕССОРНОЙ МАШИНЫ(54) ROTOR SCREW COMPRESSOR MACHINE

Изобретение относитс  к компрессоростроению , а именно к конструкци м роторов винтовых компрессорных машин.The invention relates to a compressor industry, namely to the designs of rotors of screw compressor machines.

По основному авт.св. № 883558 известен -ротор винтовой компрессорной машины, содержащий винт с охлаждаемой полостью, закрепленный на валах , имеющих осевые каналы, и расположенный в полости вытеснитель, имеющий форму, соответствующую конфигурации полости, причем на внешней поверхности вытеснител  выполнен винтовой канал 1.According to the main auth. No. 883558 is known a rotor of a screw compressor machine, containing a screw with a cooled cavity, mounted on shafts having axial channels, and a propellant located in the cavity, having a shape corresponding to the configuration of the cavity, with the screw channel 1 being made on the outer surface of the displacer.

Однако в указанном роторе не обеспечиваетс  достаточно эффективное охлаждение.However, cooling in the indicated rotor is not sufficiently efficient.

Целью изобретени   вл етс  интен .сификаци  охлаждени .The aim of the invention is to intensify cooling.

Указанна  цель достигаетс  тем, что впс1дины винтового канала вытеснител  имеют зубчатую поверхность .This goal is achieved in that the vsp1 of the screw channel of the displacer have a serrated surface.

На фиг.1 изображен ротор, продольный разрез; на фиг.2 - разрез А-А на фиг.1.Figure 1 shows the rotor, a longitudinal section; figure 2 - section aa in figure 1.

Ротор винтовой компрессорной машины содержит винт 1 с охлаждаемой полостью 2, закрепленный на валах 3 и 4, имеющих сорсные каналы 5 и 6,The rotor of the screw compressor machine contains a screw 1 with a cooled cavity 2, mounted on shafts 3 and 4, having sour channels 5 and 6,

и расположенный в полости 2 вытеснитель 7, имеющий форму, соответствующую конфигурации полости 2, причем на внешней поверхности вытеснител  7 выполнен винтовой канал 8, впадины которого имеют зубчатую поверхность 9,and located in the cavity 2, the displacer 7, having a shape corresponding to the configuration of the cavity 2, and on the outer surface of the displacer 7 there is a screw channel 8, the depressions of which have a serrated surface 9,

При вращении ротора охлал аквдгт жидкость перекачиваетс  с помощью As the rotor rotates, the akdgt cooled liquid is pumped through

10 вытеснител  7 с винтовым каналом 8 из кансша 5 вала 3 в канал 6 вала 4, охлажда  винт 1. Благодар  тому, что впадины винтового канала вытеснител  7 имеют зубчатую поверхность 10 displacer 7 with a screw channel 8 from shaft 5 of shaft 3 into channel 6 of shaft 4, cooling screw 1. Due to the fact that the depressions of the screw channel of displacer 7 have a serrated surface

15 9, поток охла щакцей жидкости в полости 2 турбулизируетс , сксррсть его возрастает, и, следовательно, интенсифицируетс  охлаждение ротора.15 9, the flow of the cooled liquid in the cavity 2 is turbulized, its efficiency increases, and, consequently, the cooling of the rotor is intensified.
