Problems solved by technology

The traditional sand mixing vehicle uses a diesel engine as a power source and completes the sand mixing work through a hydraulic system. This technical solution not only has high noise, large emissions, high energy consumption, and complicated control system, but also the sand density of the mixed liquid, the proportion of liquid additives, The accuracy of important parameters such as the proportion of dry powder additives is low, which directly affects the quality of fracturing construction

Abstract

The invention belongs to the technical field of petroleum drilling and recovery and particularly relates to an electric drive sand mixing truck. The electric drive sand mixing truck comprises a truck chassis, a control room, a transformer, an electric discharge pump, an electric suction pump, a mixing tank stirring device, a sand conveying auger, a dry feeding system, a liquid feeding system, a suction manifold and a discharge manifold. The control room comprises a sand mixing truck automatic control system and a motor drive device. The electric drive sand mixing truck has the advantages that a motor is used as power source; compared with traditional sand mixing trucks using diesel engines and torque converters as main power output, the electric drive sand mixing truck is simple in structure, novel and reasonable in design, low in cost, low in noise, low in discharge, simple to control, high in sand-liquid matching precision, and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling, in particular to an electrically driven sand mixing vehicle. Background technique [0002] Fracturing operation is one of the most effective measures to stabilize and increase production in oil fields. This operation is completed through a series of fracturing units. The main equipment includes fracturing trucks, sand mixing trucks, instrument trucks, manifold trucks and some supporting equipment Liquid tank trucks, sand trucks, etc. Among them, the sand mixer truck is one of the main equipment in the fracturing construction equipment, and its performance is one of the main factors that determine the success or failure of the fracturing operation. The sand mixing truck is mainly used for mixing, stirring, and transporting sand liquid and other media required for fracturing operations. The traditional sand mixing vehicle uses a diesel engine as a power source and completes the sand mix...
