POWER UNIT OF A PUMPING UNIT FOR DEEP-PENETRATING HYDRAULIC FRACTURING OF BRIDGES IN ISOLATED CAVITIES OF OIL AND GAS FORMATIONS Russian patent published in 2024 - IPC F04B47/00 

FIELD: oil and gas industry.

SUBSTANCE: units for hydraulic fracturing of oil and gas formations. The technical result is achieved in the power unit of a pumping unit for deep-penetrating hydraulic fracturing of bridges in isolated cavities of oil and gas formations, containing an internal combustion engine with an effective power of 2000 to 3000 hp, a hydraulic pump and a two-shaft, two-flow, multi-speed, high-speed gearbox, made with three gears with friction clutches in the additional power flow and with two gears with friction clutches in the main power flow, the intermediate shaft of which is connected to the internal combustion engine through a planetary gearbox that increases the speed, and the load shaft is equipped with a disc brake and through a speed-reducing planetary gearbox it is connected to the cylinder-planetary reduction gearbox of the hydraulic pump.

EFFECT: increased operational reliability, simplified layout and reduced size along the length of the gearbox, ensuring its effective use for deep-penetrating hydraulic fracturing of oil and gas formations.
