The invention discloses semitrailer-mounted
turbine fracturing equipment. Straight-line connection and special
chassis design of the whole equipment can double reduce center of gravity of the equipment, stability and safety are better ensured, the structure is simpler, the
investment cost and the operation cost are lowered, risks of the whole breakdown of fracturing sites are reduced, transmissionis better, and the semitrailer-mounted
turbine fracturing equipment is suitable for
continuous operation working conditions with long time and large load. By improving a
plunger pump, optimization ofrotating center distances of a
crank throw and a
crankshaft makes rated power input of the
crank throw and the
crankshaft increase to 5000-7000 hp, optimization of the
transmission ratio of an integrated reduction gearbox on the
plunger pump makes the maximum input speed of the integrated reduction gearbox reach 16000 rpm, and ultra-high speed enables reduction gearboxes to be directly connectedwith a
turbine engine so as to the solve the problems that turbine fracturing equipment slows down depending on the two reduction gearboxes, and weight of the whole semitrailer is reduced, and boundary dimension of the semitrailer-mounted turbine fracturing equipment is reduced.
