Claims (2)

1. Способ откачки природного газа из отключаемого участка газопровода в действующий газопровод при необходимости производства планово-профилактических и ремонтных работ газоперекачивающими агрегатами компрессорных цехов газокомпрессорной станции, отличающийся тем, что, с целью снижения давления перед стравливанием в атмосферу в отключаемом участке газопровода и на входе компрессорного цеха компремирующего этот газопровод, указанный компремирующий цех должен быть первым по ходу газа при последовательном включении других компрессорных цехов, где газ с выхода указанного компремирующего цеха подают на вход других компремирующих цехов для увеличения общей степени повышения давления последовательно работающих компремирующих цехов, исключающего явления помпажа на газоперекачивающих агрегатах из-за снижения давления и расхода газа на входе первого по ходу газа компрессорного цеха.1. A method of pumping natural gas from a disconnected section of a gas pipeline into an existing gas pipeline, if necessary, for scheduled maintenance and repair work by gas pumping units of the compressor shops of a gas compressor station, characterized in that, in order to reduce pressure before venting to the atmosphere in the disconnected section of the gas pipeline and at the compressor inlet Compressing workshop for this gas pipeline, the specified compression workshop should be the first along the gas during the subsequent switching on of other compressors workshops, where the gas from the outlet of the said compression shop is supplied to the input of other compression shops to increase the overall degree of pressure increase of the sequentially working compression shops, eliminating the phenomenon of surge on gas pumping units due to the decrease in pressure and gas flow rate at the inlet of the first compressor gas passage along the gas. 2. Устройство для осуществления способа по п. 1, отличающееся тем, что на линии межцеховой перемычки, соединяющей входные контура компрессорных цехов последовательно к установленным на них кранам, устанавливают дополнительный кран, а между последовательно установленными кранами врезают перемычку с кранами, соединяющую входную межцеховую перемычку с выходными коллекторами аппаратов воздушного охлаждения газа соседних цехов. 2. A device for implementing the method according to claim 1, characterized in that on the line of the inter-shop jumper connecting the input circuits of the compressor shops in series to the cranes installed on them, an additional crane is installed, and a jumper with cranes is connected between the series-installed cranes connecting the input inter-shop jumper with output collectors of gas air coolers of neighboring workshops.
