Description

technical field [0001] The invention relates to the field of performance testing of a hydraulic percussion drilling tool, in particular to a performance testing device and a testing method for a horizontal directional drilling traversing percussion drilling tool. Background technique [0002] At present, the performance test of hydraulic percussion drilling tools mainly includes the measurement of parameters such as impact energy measurement, impact frequency calibration, working flow rate and rated working pressure, among which the most important is the impact energy test. Common test methods mainly include impact velocity method and dynamic method. The impact velocity method is divided into contact method, electromagnetic induction method and high-speed camera method, while the dynamic method for measuring impact energy includes stress wave method and impact force method.

AI Technical Summary

Problems solved by technology

[0004] Most of the conventional testing methods for percussion drilling tool performance parameters are contact testing systems, such as the contact method, stress wave method and impact force method to measure impact energy. They are all directly contacted between the impacting body and the impacted body, so the testing device must be built in In the percussion drilling system, the difficulty of sensor arrangement and test device design is increased, and the test accuracy is reduced

[0005] Although the electromagnetic induction method and the high-speed camera method are non-contact measurement methods, they need to destroy the structure of the percussion drilling tool. At the same time, the accuracy of the test data is difficult to control, which will easily lead to the destruction of the test system, and the frequency of update and maintenance is high.

Moreover, this type of impact energy test method has its own limitations. It also faces problems such as high sensor layout difficulty and difficult data collection. The impact energy parameters cannot be accurately measured, or the test device cannot work stably due to the influence of the drilling tool structure, resulting in Difficult to obtain results and complex testing process

The complexity of the test device structure also increases the difficulty and cost of equipment maintenance
