Description

(54) ВИНТОВОЙ КОМПРЕССОР(54) SCREW COMPRESSOR

Изобретение относитс к компрессоростроению , а именно к винтовым компрессорам;This invention relates to a compressor industry, namely to screw compressors;

Известен винтовой компрессор, содержапщй корпус с рабочей полостью, камерами всасывани и нагнетани , установленные в рабочей полости взаимодействующие винтовые роторы, кахцщй из кото;ж1х имеет внутреннкно полость, сооб14енную с каналом дл подвода охлаждающей жидкости, выполненным в роторе со стороны камеры всасывани , и св занную через радиальные отверсти в теле последнего с рабочей полостью, и патрубок дл подвода газа ij A screw compressor is known, a housing with a working cavity, suction and discharge chambers, interacting screw rotors installed in the working cavity, each of which has a cavity internally connected to a coolant channel in the rotor from the suction chamber side, and tied through the radial holes in the body of the latter with the working cavity, and a pipe for supplying gas ij

Недостатком известного компрессора вл етс плохбе охлаждение при его вертикальном юполнении.A disadvantage of the known compressor is poor cooling with its vertical completion.

Цель изобретени - улучшение охлёикдени при вертикальном выполнении компрессора и расположении камеры всасывани в верхней части корпуса.The purpose of the invention is to improve the cooling of the air when the compressor is vertical and the suction chamber is located in the upper part of the housing.

Указанна цель достигаетс тем, что компрессор снабжен вторым патрубком дл подвода газа, каждый пат|рубок расположен в канале дл подвада охлаждающей жидкости и сообщен с внутренней полостью, а последн соединена с камерой всасывани .This goal is achieved by the fact that the compressor is equipped with a second gas inlet, each patch is located in the channel for the coolant basement and communicates with the internal cavity, and the latter is connected to the suction chamber.

В теле каждого ротора выполнены каналы с входными отверсти ми в нижней и выходными fe верхней части внутренней полости, причем в выходных отверсти х установлены распылители.In the body of each rotor, channels with inlets in the lower and outlet fe of the upper part of the internal cavity are made, and sprayers are installed in the outlet openings.

На чертеже представлен предлагае- мый винтовый компрессор, продольный разрез.The drawing shows the proposed screw compressor, longitudinal section.

Компрессор содержиткорпус 1 с The compressor contains a casing of 1 s

10 рабочей полостью 2, камерами 3 и 4 всасывани и нагнетани , установленные в рабочей полрсти 2 взаимо- действующие винтовые роторы 5, каждый из которлх имеет энутреннк о полость 6, сообщенную с каналом 7 дл подвода охлаждающей жидкости, выполненным в роторе 5 со стороны камеры 3 всасывани , и св занную через радиальные отверсти 8 в теле 9 10 working cavity 2, chambers 3 and 4 suction and discharge, installed in the working shelf 2, interacting screw rotors 5, each of which has an internal cavity 6 connected to channel 7 for supplying coolant made in the rotor 5 from the chamber side 3 suction and connected through radial holes 8 in body 9

Claims

20 last with a working cavity 2, and a branch pipe 10 for a supply. The compressor is provided with a second pipe 11 for supplying gas, each pipe 11 is located in the channel 7 for supplying coolant and communicates with the internal cavity 6, and the latter is connected to the suction chamber 3. In addition, channels 12 are provided in the body 9 of each rotor 5 with 13 holes in the bottom 14 and output 15 in the upper 16 part of the internal cavity b, and nozzles 17 are installed in the outlet holes 15, Rotors 5 are provided with holes 18. When During the compressor operation, the cooling fluid through the channel 7 enters the cavity b of each rotor 5, from where it enters through the openings 8 into the working cavity 2 and cools not only the rotor 5, but also the housing 1, In addition, suction through the inlet Ii {1gas enters b and when leaving it through the hole and 18 into chamber 3 is cooled with liquid coming from nozzles 17. Thus, supplying the compressor with additional nozzles for supplying gas and feeding it into the internal cavities of the rotor connected to the suction chamber, as well as connecting channels to the body of each rotor. The lower and upper parts of the internal cavities and equipped with the latest sprays improve cooling when the compressor is vertical. Claim 1. Screw compressor, co-assembled case with working cavity, suction and discharge chambers, interacting screw rotors installed in the working cavity, each of which has an internal cavity connected to the coolant supply channel executed in the rotor from the suction chamber side, and connected through the radial holes in the body of the latter with the working cavity, and a gas supply nozzle, characterized in that, in order to improve cooling during the vertical implementation of the compressor and enii suction chamber in the upper housing portion, a compressor provided with a second conduit for conveying gas, each nozzle arranged in the duct for supplying cooling fluid and communicates with an internal cavity, and the latter is connected to the suction chamber ..

2. Compressor pop. 1, characterized in that in the body. Each rotor has channels with inlets in the bottom and outlets in the upper part of the inner cavity, with sprayers installed in the outlets.
