Semitrailer-mounted turbine fracturing equipment

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.

Five-cylinder plunger pump with integral power end structure

The invention discloses a five-cylinder plunger pump with an integral power end structure. According to the five-cylinder plunger pump, an integral welding structure is adopted for a crankshaft box body and a crosshead box body in a five-cylinder plunger pump power end assembly, so that the structural strength of the power end assembly is higher, the supporting stability is better, and the whole pump vibration can be reduced; the cylinder spacing is 13-14 inches, the bearing area of connecting rods, crossheads and bearing bushes is increased, a guarantee is provided for the output of the high-power of the five-cylinder plunger pump, the high-power five-cylinder plunger pump can effectively solve the problem that the shale gas fracturing well site area is narrow and the required fracturingequipment is relatively large, the use of equipment can be reduced, and the wellsite arrangement is facilitated; the 11-inches long-stroke design can better realize large-displacement operation requirements and improve the operation efficiency; and according to the multi-point supporting design of crankcase bodies, crosshead box bodies and the hydraulic end assembly, the supporting strength of thefive-cylinder plunger pump can be improved, the vibration is reduced, the high-load operation is better guaranteed, and the operation is more stable.
