1. Система откачки газа из компрессоров газоперекачивающих агрегатов компрессорного цеха магистрального трубопровода, содержащая трубопроводы с запорными кранами, компрессоры, эжектор, всас которого сообщен с отключаемыми участками трубопроводов, содержащих компрессоры и ограниченных запорными кранами перед каждым компрессором и за каждым компрессором, а вход и выход эжектора сообщены соответственно с коллектором нагнетания за компрессорами и коллектором всасывания перед компрессорами, к которым посредством трубопроводов выхода и входа в компрессор с запорными кранами подключены все компрессоры цеха, отличающаяся тем, что система снабжена только одним эжектором, позволяющим обеспечить откачку газа из нескольких компрессоров одновременно, тем самым сокращая время откачки и решая заявленную задачу.1. A system for pumping gas from compressors of gas pumping units of the compressor shop of the main pipeline, comprising pipelines with shut-off valves, compressors, an ejector, the suction of which is connected to disconnectable sections of pipelines containing compressors and limited by shut-off valves in front of each compressor and behind each compressor, and the input and output the ejectors are respectively communicated with the discharge manifold behind the compressors and the suction manifold in front of the compressors, to which all the compressors of the workshop are connected via the outlet and inlet pipes to the compressor with shut-off valves, characterized in that the system is equipped with only one ejector, which allows pumping gas from several compressors at a time, thereby reducing pumping time and solving the stated problem. 2. Способ откачки газа из компрессоров газоперекачивающих агрегатов, включающий остановку одного или нескольких компрессоров, перекрытие посредством запорных кранов участков входных и выходных трубопроводов компрессоров, открытие кранов входа, выхода и всаса эжектора, поступление газа из участков входных и выходных трубопроводов и собственно компрессоров на всас эжектора, эжектирование в эжекторе газа из компрессоров активным газом из коллектора нагнетания и откачивание его в коллектор всасывания, отличающийся тем, что эжектированный газ направляют в коллектор всасывания, из одного или нескольких компрессоров, в том числе одновременно, с помощью одного эжектора.2. A method of pumping gas from the compressors of gas pumping units, including stopping one or more compressors, shutting off the sections of the compressor inlet and outlet pipelines with shut-off valves, opening the inlet, outlet and suction valves of the ejector, supplying gas from the sections of the inlet and outlet pipelines and the compressors themselves to the suction ejector, ejecting gas from the compressors in the ejector with active gas from the discharge manifold and pumping it to the suction manifold, characterized in that the ejected gas is sent to the suction manifold from one or more compressors, including using one ejector at the same time.
