The invention belongs to the technical field of fracturing construction
mechanization, and particularly provides a full-automatic liquid adding device for fracturing construction and an adding calibration method. The full-automatic liquid adding device comprises a prying frame, an engine, a
transfer case, a hydraulic device, a liquid adding pump, a metering calibration tank, a liquid additive tank, a liquid supply pump and a
control unit, wherein the input ends of the engine, the
transfer case and the hydraulic device are sequentially connected; the output end of the hydraulic device is connected with the liquid supply pump and the liquid adding pump; the liquid supply pump is connected with an inlet of the liquid additive tank; an outlet of the liquid additive tank is sequentially connected with inlets of the metering calibration tank, the liquid adding pump and the liquid additive tank; the
control unit is electrically connected with the engine, the
transfer case, the hydraulic device, the liquid adding pump, the metering calibration tank, the liquid supply pump and the liquid additive tank; and the current situation that in the fracturing construction process, the liquid additive adding precision is large in adding difficulty and discontinuous is avoided, the
mechanization and
automation degree of fracturing construction is improved, meanwhile, the construction quality and potential safety hazards are effectively eliminated, and the construction success rate is increased.
