Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides an electric drive mixing equipment, which solves the problem of the bulky volume of the existing mixing equipment for oil and gas fields. The common electric driving force unit occupies a large area, and the frequency converter and the motor are not used. Integrated together, a separate frequency conversion cabinet is required, 10m 3 / min or even 12m 3 Mixing equipment above / min will not be transported by vehicle

Abstract

The invention discloses an electric-drive mixing device, and relates to the technical field of mixing equipment. The electric-drive mixing device comprises a motor power unit, a mixing tank, a discharge centrifugal pump, a suction centrifugal pump, a powder tank, a control chamber, a drainage manifold, a water-powder mixing manifold, a chemical adding pump and a suction header. The mixing tank is fixedly mounted on one side of the motor power unit, and the control chamber is fixedly mounted on one side of the mixing tank. The electric-drive mixing device has the advantages that a selected motor is a variable-frequency all-in-one machine, that is to say, a frequency converter is integrated with the motor, and there is no independent frequency conversion cabinet, so that the occupied space is remarkably saved, and the device is suitable for vehicle transportation; the variable-frequency all-in-one machine has much lower heat than the motor, a radiator is integrated to a cabinet casing of the motor and the frequency converter, and no plate-fin radiating holes are provided; a large-channel air duct is arranged at a motor and frequency converter casing position of a fan, and accordingly, blockage is avoided.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to an electric drive mixing equipment. Background technique [0002] Fracturing is the main measure to increase production in oil and gas fields. Currently, fracturing operations at home and abroad, especially shale gas fracturing construction sites, require a large amount of fracturing base fluid. The application of fracturing fluid mixing vehicles is becoming more and more extensive, but with the increase of fracturing scale, the volume of fluid distribution is increasing, and the demand for mixing equipment is also increasing. [0003] In China's oil and gas field fracturing operations, the configuration of the power transmission system used in the mixing equipment is that the diesel engine is connected to the transfer case to drive the hydraulic system to work. That is to say, the power source is the diesel engine, which drives the execution components through the hydra...
