The invention relates to the technical field of fracturing equipment, and provides a power end assembly, a fracturing pump and an operation vehicle, the power end assembly comprises a shell, an input shaft, a crankshaft and a connecting rod mechanism; an input hole is formed in one side of the shell in the first direction, and a sliding rail through hole is formed in one side of the shell in the direction opposite to the first direction. The input shaft is rotationally connected to the input hole; the connecting rod mechanism comprises a small connecting rod and a crosshead, the small connecting rod is connected with the crosshead, the crosshead is slidably connected to the sliding rail through hole, and the small connecting rod is suitable for being connected with a plunger at the fluid end. According to the power end assembly, the fracturing pump and the operation vehicle, the input shaft and the small connecting rod are arranged on the opposite side of the first direction of the shell, the input shaft and the small connecting rod are parallel to each other, and then the axis direction of the input shaft can be parallel to the movement direction of the plunger. The fracturing pump adopting the power end assembly can be arranged in the length direction of a vehicle, and enough space can be provided for operation and maintenance of the fracturing pump.
Description
technical field [0001] The invention relates to the technical field of fracturing equipment, in particular to a power end assembly, a fracturing pump and an operating vehicle. Background technique [0002] In the process of oil and gas development, fracturing pumps are widely used, such as oil and gas field fracturing water injection, acid fracturing, etc., and are important measures to improve oil recovery, gas recovery, water injection and recovery. [0003] The mechanical fracturing pumps widely used in the market can only be arranged horizontally on the vehicle under the influence of the direction of plunger movement and the direction of input shaft when they are arranged on the equipment. Due to the limitation of the width of the vehicle body, the operation and maintenance are difficult convenient. Moreover, the existing mechanical fracturing pump deceleration mechanism is one-stage deceleration. In order to achieve a suitable deceleration ratio, the volume of the dece...
