Abstract

The invention discloses a power test valve block for a power matching test of a rotary drilling rig. The power test valve block comprises a pilot valve, stop valves, flowmeters and pressure sensors, wherein the stop valves comprise a first stop valve and a second stop valve; the pressure sensors comprise a first pressure sensor and a second pressure sensor; the flowmeters comprise a first flowmeter and a second flowmeter. The invention further discloses a power matching test device for the rotary drilling rig. The power matching test device comprises a pilot pump, overflow valves, main pumps,reversing valves, a power head motor and the power test valve block, wherein the reversing valves comprise a first reversing valve and a second reversing valve; the overflow valves comprise a first overflow valve, a second overflow valve and a third overflow valve; the main pumps comprise a first main pump and a second main pump. The power test valve block and the power matching test device are simple in structure and convenient to use, test cost is low, basis is provided for adjusting absorbing power of the pumps and output power of an engine, so that good matching of the absorbing power of the pumps with the output power of the engine is realized, fuel economy of the rotary drilling rig is guaranteed, and the service life of the rotary drilling rig is prolonged.

Description

technical field [0001] The invention relates to a power test valve block, a test device and a test method for a power matching test of a rotary drilling rig Background technique [0002] The rotary drilling rig has many advantages such as large output torque, fast drilling speed, flexible and easy operation, high hole quality, and convenient matching with various drilling tools. The rotary drilling rig is a fully hydraulically driven pile foundation construction machine. All its actuators are driven by the hydraulic system, and the hydraulic system absorbs the output power of the engine. Generally, the absorbed power of the hydraulic system of the rotary drilling rig should reach the total output power of the engine. The output power is about 85%. Only when the absorbed power of the hydraulic system is well matched with the output power of the engine can the fuel economy of the rotary drilling rig be improved. Otherwise, the fuel efficiency of the engine will not be high, an...
