Abstract: The present invention discloses a semi-trailer-loaded turbine fracturing equipment, which adopts a linear connection of the whole equipment and a special chassis design, so that the center of gravity is double lowered to guarantee its stability and safety, the structure is simpler, the investment and operation costs are decreased, the risk of total breakdown of the fracturing site is reduced, and the equipment has a good transmission performance and is suitable for continuous operation conditions with long time and heavy load. The plunger pump is improved in that the distance between the center of rotation of the bellcrank and the center of rotation of the crankshaft is optimized so that the rated input power is increased to 5000-7000 hp, the transmission ratio of the reduction gearbox integrated on the plunger pump is optimized so that the maximum input speed can reach 16000 rpm, the superhigh speed allows the reduction gearbox to be connected directly to the turbine engine to address the problem that the turbine fracturing equipment is decelerated through two reduction gearboxes, thus decreasing the weight of the vehicle and reducing the overall size of the equipment.
