In steps of 5, slush pump 1 is opened, first progress low pressure trial operation, checked again in low pressure operation stage, test
The each connecting interface position of device whether good seal, if it is unobstructed；Check each biography in control unit and data acquisition unit
Whether sensor has signal fluctuation, and whether signal transmission is normal.
In step 6, flow divider 2 is adjusted using control unit 14, acquires the number that each sensor obtains under different displacements
According to thus the running parameter and characteristic of comprehensive analysis drilling tool 8 to be measured.
In step 7, slush pump 1 is closed, is successively removed according to the order of connection of experimental provision, experimental provision is put after dismounting
Origin-location is gone back to, is put neat；When sensor is removed, pays attention to handling with care, keep properly, in order to avoid influence its measurement accuracy.
In step 8, under the conditions of choosing different displacements, the data that the discharge capacity metastable stage collects are carried out at analysis
Reason, finally obtains running parameter and working characteristics of the drilling tool 8 to be measured under the conditions of different displacements.
The above, only specific embodiments of the present invention cannot limit the range that invention is implemented with it, so it is equivalent
The displacement of component, or according to equivalent variations made by the invention patent protection scope and modification, should all still fall within what this patent was covered
Scope.In addition, between technical characteristic and technical characteristic in the present invention, between technical characteristic and technical solution, technical solution with
Use can be freely combined between technical solution.
