Problems solved by technology

However, since the engine is generally all speeded up and the hydraulic pump and hydraulic motor are adjusted at the same time, the standby power of the whole machine is relatively large when the maximum power is set, and the heat loss of the whole machine system is relatively large, which is a waste of resources.

Abstract

The embodiments of the present invention provide a fracturing vehicle control method and device and relates to the technical field of fracturing equipment control. According to the fracturing vehiclecontrol method and device, firstly a hydraulic motor, a hydraulic pump and an engine that need to be operated are selected through a preset pressure protection value and a preset construction displacement value such that the actual output total power of the hydraulic motor, the hydraulic pump and the engine are matched with a maximum output power which is determined through the preset pressure protection value and the preset construction displacement value, and the increase of extra work caused by excessive actual output total power is avoided. Based on an obtained current displacement value and the preset construction displacement value, the output current of the hydraulic motor or the hydraulic pump is adjusted, and thus the purpose of high vehicle utilization efficiency, small power loss and energy saving under different power is achieved.

Description

technical field [0001] The invention relates to the technical field of fracturing equipment control, in particular to a method and device for controlling a fracturing vehicle. Background technique [0002] The hydraulic fracturing truck is a kind of fracturing equipment in the production stimulation operation of fracturing construction, which is different from the conventional fracturing truck in the process of power transmission. The power system of hydraulic fracturing is composed of multiple engines, and the transmission chain system is a distributed hydraulic motor driving the fracturing pump to work. In the process of construction and use, different fracturing construction designs require that the output displacement of the large pump and the construction pressure are not necessarily the same, that is, the output power of the fracturing truck is not the same. Therefore, under the condition of a certain maximum output power (when the displacement and overpressure protec...
