Beschreibung
Zusammenfassung:	The present invention discloses a double-motor double-pump electric drive fracturing semi-trailer, including a semi-trailer, plunger pumps, radiators, and an electrical control cabinet, and further including electric motors and an inversion unit. The plunger pumps, the radiators, the electrical control cabinet, the electric motors, and the inversion unit are integrated in the semi-trailer. There are two electric motors, two plunger pumps, and two radiators. The inversion unit is disposed on a gooseneck of the semi-trailer. An output terminal of the inversion unit separately drives the two electric motors. The other end of each of the two electric motors is connected to the plunger pump. The radiators cool the lubricating oil in the plunger pump. The electrical control cabinet is used to implement local manipulation of the double-motor double-pump electric drive fracturing semi-trailer. Beneficial effects: An electric motor is used to drive a plunger pump through a transmission shaft, to achieve a small volume, economy, energy conservation, and environmental friendliness. The plunger pumps have improved power compared with a single-pump, and a design of double pumps driven by double electric motors is adopted in entire fracturing equipment, thereby significantly improving the output power of the fracturing equipment and better satisfying the use requirements.
