Abstract
Изобретение позвол ет упростить монтаж и повысить надежность работы компрессора. Разгрузочный поршень (РП) 4 установлен с образованием камер 8 и 9 высокого и низкого давлени коаксиально торцовому уплотнению, выполненному в виде подпружиненного уплотнител 5 и кольца 6. Стык уплотнител и кольца расположен внутри РП 4 в камере 9, РП 4 закреплен на кольце 6 с противоположной от ротора 2 стороны. Подшипник 10 вала 3 разгружаетс от действующих на него усилий за счет подачи разгружающей среды в камеру 8, что приводит к осевому воздействию РП 4 через кольцо 6 на подшипник 10. 1 ил.The invention allows to simplify installation and increase the reliability of the compressor. The discharge piston (RP) 4 is installed with the formation of chambers 8 and 9 of high and low pressure coaxial to the mechanical seal, made in the form of a spring-loaded seal 5 and ring 6. The joint of the seal and ring is located inside RP 4 in chamber 9, RP 4 is fixed on ring 6 s opposite to the rotor 2 side. The bearing 10 of the shaft 3 is discharged from the forces acting on it by supplying the unloading medium into the chamber 8, which leads to the axial action of the RP 4 through the ring 6 on the bearing 10. 1 sludge.

Изобретение относитс к компрес- соростроению и касаетс винтовых ком прессоров.The invention relates to compressor building and concerns screw compressors.
Цель изобретени - упрощение мон тажа и повышение надежности работы.The purpose of the invention is to simplify installation and increase reliability.
На чертеже изображен винтовой ком прессор, продольный разрез,The drawing shows a screw compressor, a longitudinal section,
Винтовой компрессор -со держит корпус 1 с установленным.в нем ведущим ротором.2, вал 3 которого снабжен разгрузочным поршнем 4 и торцовым уплотнением, выполненным в виде подпружиненного уплотнител 5 и кольца 6, закрепленных доответственгго на противоположной от ротора 2 стенкеThe screw compressor holds the body 1 with the leading rotor installed in it.2, the shaft 3 of which is equipped with a discharge piston 4 and a mechanical seal made in the form of a spring-loaded seal 5 and a ring 6 fixed to the wall opposite to the rotor 2
7корпуса 1 и валу 3, Поршень 4 уста новлен с образованием камер высокого7cases 1 and shaft 3, Piston 4 is installed with the formation of high chambers
8и низкого 9 давлени коаксиально торцовому уплотнению и закреплен на кольце 6 с противоположной от ротора 2 стороны, причем стык подпружиненного уплотнител 5 и кольца 6 расположен внутри поршн 4 в камере 9 низ кого давлени . Вал 3 установлен на подшипниках 10, а в стенке 7 корпуса 1 выполнено отверстие 11 дн подвода разгружающей среды в камеру 8 высо- .кого давлени .8 and low pressure 9 are coaxial to the mechanical seal and fixed on the ring 6 on the side opposite to the rotor 2, the joint of the spring-loaded seal 5 and ring 6 located inside the piston 4 in the low pressure chamber 9. The shaft 3 is mounted on bearings 10, and in the wall 7 of the housing 1 a hole 11 days is made to supply unloading medium to the high pressure chamber 8.
Винтовой компрессор работает следующим образом.Screw compressor works as follows.

При вращении ведущего ротора 2, взаимодействующего с ведомым ротором (не показан) происходит всасывание, г сжатие и нагнетание газа. Возникающие при этом усили действуют на подшипник 10, который разгружаетс от них за счет подачи разгружающей среды через-отверстие 11 в камеру 8 вы- 10 сокого давлени , что приводит к осевому воздействию разгрузочного поршн 4 через кольцо 6 на подшипник 10.During the rotation of the leading rotor 2, interacting with the driven rotor (not shown), suction occurs, g is compressed and gas is injected. The forces that arise in this case act on the bearing 10, which is discharged from them by supplying the unloading medium through the orifice 11 to the high pressure chamber 8, which leads to the axial effect of the unloading piston 4 through the ring 6 on the bearing 10.
