Problems solved by technology

[0003] At present, the rotation speed of the fracturing pump motor cannot be adjusted during the opening of the fracturing pump unit. Only the mechanical hydraulic transmission can be used to realize the speed change of the fracturing pump motor according to the set gear, which has low efficiency and poor precision. Moreover, the fracturing pump After the group is injected, the pressure in the injection hole continues to rise, and the rise is large, which may easily cause the pressure in the injection hole of the coal seam to be too high after the fracturing is completed, resulting in low safety of the fracturing operation

Abstract

The invention provides a fracturing pump set control system and method, and the system comprises a central control unit which is used for receiving a target pressure value of a fracturing pump; the fracturing pump sensor group is used for detecting the actual pressure value of the fracturing pump; the fracturing pump controller is electrically connected with the central control unit and the fracturing pump sensor set and used for comparing the target pressure value with the actual pressure value and judging whether the actual pressure value suddenly drops or not; the frequency converter is electrically connected with the fracturing pump controller; compared with the prior art, the coal seam fracturing system has the advantages that the rotating speed of the fracturing pump motor can be rapidly and continuously adjusted, the automation degree is high, the coal seam fracturing efficiency is effectively improved, and the safety of coal seam fracturing operation is higher.

Description

technical field [0001] The present application relates to the technical field of fracturing pump sets, in particular to a control system and control method for fracturing pump sets. Background technique [0002] Coal mine underground fracturing technology is a coal mine surrounding rock control technology. This technology is mainly used in the weakening of hard roof and pressure relief of high stress roadway surrounding rock. The implementation method of this technology is to use fracturing pumps to inject High-pressure water or other fracturing media can cause cracks in the coal seam to develop and grow, thereby effectively promoting the prevention and control of rock burst, pressure relief in dynamic pressure roadways, weakening of the roof of the island working face, improvement of hard top coal cavitation and stagnation of the roof of the working face Regional fracturing modification, etc. [0003] At present, the rotation speed of the fracturing pump motor cannot be ad...
