The working information stored in the identification unit 20 changes every time the fluid end 320 is replaced, and the working information identified by the detection unit 10 changes accordingly, so that the accumulated working time of each fluid end 320 and the replacement frequency of the fracturing pump replacing the fluid end 320 can be counted according to the working information, and thus, the accuracy of calculating the accumulated working time of the fluid end 320 and the replacement frequency of the fracturing pump replacing the fluid end 320 is improved.
For convenience and brevity of description, the types of the specific components included in the method described above may refer to the corresponding descriptions in the foregoing system, and are not described in too much detail here.
