Embodiment Construction

[0028] The screw drilling tool test bench is mainly used to test the screw drilling tool 12.

[0029] The basic principle of performance testing of screw drilling tools: under the premise of keeping the volume flow rate of the circulating liquid flowing into the screw drilling tool at a given value, by applying different torque loads at the power output end of the screw drilling tool, the drilling tool can be operated under different braking torques. Work stably under different working conditions, test the output torque T, output speed n, circulation flow Q1, drilling tool inlet pressure p1, outlet pressure p2 and other parameters of the drilling tool under different working conditions, and obtain the performance of the screw drilling tool after data processing Parameter tables and characteristic curves.

[0030] The screw drilling tool testing system is mainly composed of: power system, circulation system, test bench host, hydraulic system, measurement and control system and ...

Abstract

The invention discloses a combined vibration damper of a screw drill complete machine test-bed and a manufacturing method thereof. The combined vibration damper comprises a vibration attenuation base which comprises a loading system base, a first clamping system base and a second clamping system base, wherein the loading system base is arranged on an equipment foundation in a rigidity way; the first clamping system base and the second clamping system base are connected into a whole through a bolt and are arranged on the equipment foundation through a rubber vibration attenuation block; an interval of 30-50 mm is reserved between the loading system base and each clamping system base; the first clamping system base and the second clamping system base are respectively internally provided with a plurality of cubic cavities with an equal size; the volume of each cubic cavity is 0.1-0.2 cubic meter; discrete type balance weight sand is respectively filled into the cubic cavities, and the filling efficiency is 80-90 %; and the weight of the balance weight sand is 25-35 % of the total weight of the whole device. The test-bed is capable of restraining resonance and testing precisely in the testing process by the combined vibration damper, and the usage precision of surrounding working devices is not affected.

Description

technical field [0001] The invention relates to the technical field of a complete screw drilling tool test bench, in particular to the vibration reduction technology of a complete screw drilling tool test bench. Background technique [0002] The screw drilling tool test bench is a special test device for the input and output performance testing of the screw drilling tool as a whole. Large loading, circulation flow adjustment, collecting data such as torque, speed, pressure difference, flow rate, temperature, etc., output performance parameter tables and characteristic curves of screw drilling tools. [0003] Among them, the main engine of the test bench mainly implements the installation of the drilling tool, the clamping support, the loading of the output end of the screw drilling tool, and the output of torque and speed. [0004] In the existing screw drilling tool test bench, the host machine of the test bench vibrates greatly during the screw drilling tool testing proce...
