Embodiment Construction

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] Such as figure 1 As shown, the hydraulic system of the fracturing vehicle in the embodiment of the present invention includes an engine 1, an oil pump 2, a hydraulic motor 3 and at least one accumulator 4. The oil circuit and the low-pressure oil circuit are connected with the hydraulic motor 3, the hydraulic motor 3 is suitable for drive connection with a fracturing pump (not shown in the figure), the accumulator 4 is connected to the oil pump 2 and the The high-pressure oil circuit between the hydraulic motors 3.

[0034] Specifically, the solid line between the oil pump 2 and the hydraulic motor 3 in the figure, that is, the upper part represents the high-pressure oil circuit, and the dotted line between ...

Abstract

The invention relates to a fracturing truck hydraulic system and a control method thereof. The system comprises an engine, an oil pump, a hydraulic motor and at least one energy accumulator, the engine is in driving connection with the oil pump, the oil pump is connected with the hydraulic motor through a high-pressure oil way and a low-pressure oil way, the hydraulic motor is suitable for being in driving connection with a fracturing pump, and the energy accumulators are connected into the high-pressure oil way between the oil pump and the hydraulic motor. According to the technical scheme, the operation stability of the fracturing truck hydraulic system can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a hydraulic system of a fracturing vehicle and a control method thereof. Background technique [0002] Fracturing vehicles are increasingly used in the field of oil exploration, and the fracturing pump of the fracturing vehicle is its core component. The fracturing pump is usually driven by a hydraulic system. However, changes in the corresponding working conditions of the fracturing pump usually cause large pressure fluctuations in the hydraulic system, which will affect the normal use and life of the fracturing truck. Especially for fracturing vehicles that need to change the working environment frequently, the working conditions change more frequently, and the impact on the fluctuation of the hydraulic system will be greater. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a hydraulic system of a f...
