GAS-PUMPING UNIT Russian patent published in 2018 - IPC F04D25/02 F16L3/22 

FIELD: gas industry.

SUBSTANCE: gas pumping unit contains technological units that have technological pipelines with detachable connection for external connection of process units to each other and/or the equipment of the gas pumping unit. In this case, the technological blocks contain means for interconnection and positioning of a group of pipelines for external connection of the technological unit. Device is made in the form of a plate rigidly connected to the frame and/or structural element of the technological unit, in which the inputs/outputs of process pipelines are rigidly fixed, provided with a detachable connection. Technological block is selected from the following: compressor block; gas turbine engine block; gas turbine unit; gas turbine engine oil supply unit; oil compressor unit; unit for flushing the gas-air path of the gas turbine unit; fuel gas preparation unit; buffer gas preparation unit; block preparation of the separation (barrier) gas; an exhaust gas heat recovery unit; the anti-icing system unit; block of the gas main control system; the block of apparatuses for air cooling of gas; block of gas separators. Plate can be made of metal, the plate can be made detachable in the plane of the inputs/outputs of the technological pipelines, can have the same size of holes for fixing the inputs/outputs of technological pipelines in it. Holes can be provided with an insert with an internal diameter corresponding to the diameter of the process pipeline. Insert can be integral or detachable and fastened in the hole by threading. Joint of the pipelines may be threaded nipple.

EFFECT: invention allows to increase the unification of technological blocks, as well as to shorten the period of installation and reconstruction of the gas pumping unit.
