OIL PUMPING STATION FOR UNINTERRUPTED OPERATION Russian patent published in 2016 - IPC F17D1/08 

FIELD: oil industry.

SUBSTANCE: invention relates to oil pipeline equipment, specifically to oil pumping stations (OPS) of main oil pipelines having tank farms. OPS for uninterrupted operation, connected through a connection unit with a main oil pipeline, comprises equipment linked to a network of pipelines: strainer unit whose input is connected to connection unit, tank farm whose input is connected to output of strainer unit, booster station whose input is connected to output of tank farm, main pump station, connected to output of booster station, wherein output of main pump station via a pressure control unit is connected to connection unit, wherein output of strainer unit is connected via a check valve to input of main pump station, on pipeline connecting output of booster station to input of main pump station, after point of connection of output of check valve there is a unit of spring-loaded dump safety valves, whose output is connected to an emergency discharge reservoir, and on pipeline connecting output of strainer unit to input of tank farm, there is a disconnecting valve.

EFFECT: technical result is providing uninterrupted operation and increased safety of oil pumping station by using a check valve to switch flow of pumped oil supplied from main oil pipeline to input of main pump station during disconnection of tank farm.
