Abstract

The invention provides a fracturing truck displacement control method and a fracturing truck, and relates to the technical field of engineering machinery. The fracturing truck displacement control method comprises the following steps that a displacement value of a variable pump is set as a first displacement value and a displacement value of a motor is set as a second displacement value accordingto a target displacement value of the fracturing truck, wherein the second displacement value is greater than or equal to the first displacement value, so that when the variable pump is switched, impact is not prone to generation due to displacement mismatching when liquid arrives at the motor, and accordingly a hydraulic system is more stable when the whole fracturing truck is subjected to displacement control or adjustment; and the actual displacement value of the fracturing truck is obtained according to the first displacement value and the second displacement value, and the actual displacement value is adjusted to the target displacement value.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method for controlling the displacement of a fracturing vehicle and a fracturing vehicle. Background technique [0002] With the rapid development of the economy and the acceleration of infrastructure construction, construction machinery has played an indispensable role in it. Construction machinery is a large-scale machine that can significantly shorten the construction period, and the fracturing vehicle is one of them. It can inject high-pressure and large-volume fracturing fluid into the well, press the formation and squeeze the proppant into the well. Special purpose vehicles for cracks. It is mainly used for various fracturing operations of oil, gas, and water wells, and can also be used for hydraulic sand blasting, high-pressure hydraulic coal mining in coal mines, and high-pressure hydraulic rust removal for ships. The equipment can perform stand-alone an...
