The invention relates to a multifunctional blending and liquid supplying vehicle, which comprises a
chassis, wherein an operation platform, a hydraulic
oil tank, a
dry powder feeder, an operation box for an
electrical control system, a lorry-mounted crane and a liquid adding tank are fixedly arranged above the main beam of the
chassis, wherein a
centrifugal pump, an
exhaust manifold and a suction manifold are arranged on each of two sides of the middle part of the main beam of the
chassis, the
exhaust manifold is communicated with the water outlet of the
centrifugal pump, and the suction manifold is communicated with the water inlet of the
centrifugal pump; the liquid adding pump is fixedly arranged on the side wall of the liquid adding tank, the water inlet of the liquid adding pump is communicated with the liquid adding tank, and the water outlet of the liquid adding tank is communicated with the
exhaust manifold; a
discharge opening in the lower end of the
dry powder feeder is communicated with the exhaust manifold; the engine of the chassis is connected with a
hydraulic pump, and the
hydraulic pump is connected with the centrifugal pump, the lorry-mounted crane, the liquid adding tank and the liquid adding pump through a hydraulic multiway valve; the
electrical control system is connected with the engine of the chassis, the
hydraulic pump and the hydraulic multiway valve. The multifunctional blending and liquid supplying vehicle provided by the invention is low in cost, high in working efficiency, and can achieve various
oil field operation functions.
