Test device and method of performance of screw drill motor

Abstract

The invention relates to a test device and a test method of performance of a screw drill motor. The test method of the performance of the screw drill motor includes: testing hydraulic characteristics of a rotor of the screw drill motor under external power drive according to a reversibility principle of positive displacement hydraulic machinery, and thereby simply, comprehensively and effectively testing and evaluating various performance indexes of the screw drill motor. The test device of the performance of the screw drill motor comprises a base seat, a drive unit arranged on one side of the base seat, a fixing unit arranged on the other side of the base seat and used to fix the screw drill motor to be tested, a water tank arranged on the outer side of the base seat, a circulating pipeline used to respectively communicate an outlet and an inlet of the screw drill motor with the water tank, a throttle control unit arranged on the circulating pipeline and used to control flow rate of the screw drill motor and a detection unit used to test various basic parameters of the screw drill motor, wherein an output end of the drive unit is connected with a rotor of the screw drill motor, and drives the rotor of the screw drill motor to rotate.

Description

technical field [0001] The invention relates to a device and a method for testing the performance of a screw drilling tool, in particular to a device and a method for testing the performance of a screw drilling tool motor. Background technique [0002] At present, there are two commonly used test methods for the performance of screw drilling tools: [0003] One is the screw drilling tool test method: this method tests the output torque of the drilling tool under different simulation conditions by applying different displacement media at the drilling tool inlet and applying different counter torque loads to the drilling tool output part , output speed, circulation flow, inlet and outlet pressure and other drilling tool performance parameters. The advantage of this method is that the working mode is similar to the actual working conditions, and the test results are closer to the actual performance of the screw drilling tool; the disadvantage is that the test equipment is comp...

For example, the application number is: 201120334569.3, and the utility model patent with the invention name: "A screw drilling tool motor test bench" belongs to this method. Although this method realizes the detection of the sealing performance of the motor, the disadvantage is the pressure difference of the test. Single-point data cannot comprehensively analyze the dynamic performance of screw drilling tools
