Problems solved by technology
[0002] At present, mud pumps or high-pressure water pumps are mostly driven by electric motors, and their performance testing is only independently aimed at parameters such as the maximum flow rate, maximum load, and volumetric efficiency of the pump, but cannot be used for comprehensive testing and reflection of their dynamic performance in working conditions. The characteristic curve directly reflects its performance and process adaptability
[0003] The mud pump truck solves the problem of poor adaptability to the drilling load of the traditional electric drive mud pump, and mainly provides driving force for the screw motor at the bottom of the hole used in horizontal directional drilling in coal mines. It can realize stepless speed regulation and provide variable flow for the screw motor. , the process adaptability is strong, but there is no detection method and device for the comprehensive dynamic performance of the mud pump truck that can simulate the load in the directional drilling hole
Therefore, there is a problem of not being able to fully test and reflect the dynamic performance and optimal working range of the pump truck under the load in the directional drilling hole

Embodiment
[0039] see figure 1 , a device and method for simulating the load in a directional drilling hole to detect the dynamic performance of a mud pump truck, comprising a pulse reducer 1, a first pressure gauge 2, a needle flowmeter 3, a digital display flowmeter 4, and an in-hole Load loading device 5, second pressure gauge 6, stop valve 7, water tank 8, stop valve 9, third pressure gauge 10, safety valve 11, fourth pressure gauge 12, thermometer 13.
[0040] Open the shut-off valve 9, and through the third pressure gauge 10 and temperature gauge 13, the pressure and temperature of the suction end of the water pump can be detected. Flow meter 3 and flow meter 4 display the flow rate of the output pipeline of the water pump, and pressure gauge 2 displays the pressure of the main output pipeline. The pulse reducer can reduce the pressure fluctuation output by the mud pump truck.
[0041] The safety valve 11 can set the maximum output pressure of the mud pump truck, unload when over...

The invention relates to a pump truck performance detection device and method, belonging to the technical field of pump truck detection, and in particular to a pump truck performance detection device and method based on load simulation in a directional drilling hole. The invention is composed of a high-pressure water pump, a dynamic performance loading part, a pulse reducer, a flow monitoring unit and a pressure monitoring unit. By adjusting the set pressure of different cut-off valves and sequence valves of the load loading device in the borehole, the required working pressure and flow rate of the loading screw motor under different working conditions and the pressure loss along the borehole with different hole depths are simulated. In order to detect the dynamic performance of the mud pump truck's work output.
