Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] In the field application process of the equipment, the actual underlying structure and the actual displacement of the input are different, and the output power of the whole machine is also different. Therefore, in the actual use of the fracturing truck, when the net output power of the whole machine is constant, the more useless work the whole machine does, the lower the efficiency of the whole machine. The power source engine has different efficiencies in different speeds and load operating ranges. The power transmission components hydraulic pump and motor have different efficiency and speed of heat loss under different flow rates during the energy transmission process. The normal operation of the whole machine is mainly due to the...

Abstract

The invention discloses a fracturing truck control method and device and a fracturing truck. The fracturing truck control method comprises the steps that current working condition parameters are obtained, wherein the current working condition parameters comprise the current actual displacement and the actual pressure; an optimal operation state database is queried based on the current working condition parameters to obtain matched operation parameters of the current working condition parameters; and the fracturing truck is controlled based on the current working condition parameters and the matched operation parameters. The control speed is high, and the whole machine energy efficiency is high.

Description

technical field [0001] The invention relates to the technical field of fracturing vehicle control, in particular to a fracturing vehicle control method and device and a fracturing vehicle. Background technique [0002] The fracturing vehicle is a special vehicle used to inject high-pressure and large-volume fracturing fluid into the well, press the formation and squeeze the proppant into the fracture. It is mainly used for various fracturing operations of oil, gas and water wells. It plays an important role in oil, gas and other energy extraction operations. [0003] In the existing fracturing vehicle control method, the engine speed is usually increased to the maximum, and the hydraulic pump and the hydraulic motor are adjusted and controlled at the same time. This control method may cause the engine to fail to run in the best state at the set power, and the hydraulic system may also be in a subnormal state, resulting in a large amount of energy that cannot be output as us...
