SEMITRAILER HYDRAULIC FRACTURING PUMP UNIT Russian patent published in 2025 - IPC F04D13/02 E21B43/26 F04B53/08 

FIELD: mining.

SUBSTANCE: invention relates to oil and gas production plants, in particular, to a plant intended for injection of process liquids, proppant material, liquid-sand mixtures when performing operations to stimulate formation productivity using tubing or flexible tubing as part of a mobile hydraulic fracturing system, as well as autonomous performance of works on well flushing, hydro-sandblasting of bottom-hole zone and pressure testing of wells. Result is achieved when implementing a pumping station for hydraulic fracturing, mounted on a three-axle semitrailer, and comprising a power plant installed by means of a front bracket and a rear support, a transmission, radiator unit installed by means of L-shaped bracket, high pressure pump, two fuel tanks and a hydraulic system, which includes a lubrication tank of the mechanical part of the pump, a hydraulic tank of a radiator fan, a pump for driving a radiator fan and a fan drive motor, at that, the fan pump drive is installed by means of a trapezoidal bracket, the unit is also equipped with a pre-start independent heating, including a diesel heater of the power plant and a heater in the lubrication tank of the mechanical part of the pump, and the radiators fan hydraulic tank is located above the radiator fan drive hydraulic pump level, which excludes the possibility of pump starvation and its failure, lubrication tank of the mechanical part of the pump is made with possibility of preventing formation of a funnel and air suction and is located above the lubrication pump of the mechanical part; convenient brackets for transportation of hoses are mounted on the semitrailer.

EFFECT: implementation of the purpose of the pumping station for hydraulic fracturing on the semitrailer.
