Title:
ELECTRO-HYDRAULIC HYBRID-DRIVEN SAND BLENDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/252906
Kind Code:
A1
Abstract:
An electro-hydraulic hybrid-driven sand blending apparatus, comprising a skid base (9), electric motors, a hydraulic pump, a discharge centrifugal pump (3), a suction centrifugal pump (4), a blending tank (5), a dry-material adding system (6), a liquid adding system (7), and a sand-conveying screw conveyor system (8). The electric motors, the hydraulic pump, the discharge centrifugal pump (3), the suction centrifugal pump (4), the blending tank (5), the dry-material adding system (6), the fluid adding system (7), and the sand-conveying screw conveyor system (8) are integrated and skid-mounted on the skid base (9). Two electric motors are provided, which are a first electric motor (1) and a second electric motor (2). The first electric motor (1) drives the discharge centrifugal pump (3), and the second electric motor (2) drives the hydraulic pump, thus driving the suction centrifugal pump (4), the blending tank (5), the dry-material adding system (6), the fluid adding system (7), and the sand-conveying screw conveyor system (8). Each of the electric motors is a variable-frequency integrated electric motor.
