Abstract

The invention relates to a friction coefficient measuring device. The device comprises a measuring system and a data collecting system; a heating pipeline is arranged in a test box to simulate the friction coefficient condition of a petroleum apparatus in an underground state, the temperature of the test box can be controlled by the heating pipeline, and an air compressor is used to simulate the atmospheric pressure in the box, so the device meets measuring requirements of the friction coefficient under multiple conditions, and has a high precision and a high efficiency; when a test workpiecea is in contact with a test workpiece b, a tension sensor is in a horizontal state, and a pressure sensor is in a vertical state, so a case that a displayed value is greater than the value of a practically applied force, caused by the angle difference of the connection of the tension sensor, the pressure sensor and the test workpieces, is avoided; and an electric cylinder is used to convert torqueinto a horizontal force participating in the test, so the size of friction force f and the test value of the tension sensor have a good stability, the fluctuation range is small, and the measuring precision is high.

Description

Technical field [0001] The invention relates to the field of friction coefficient testing, in particular to a friction coefficient measuring device. Background technique [0002] In the fields of petroleum exploration and development, it is necessary to develop different new materials to adapt to various harsh environments, especially the friction coefficient between layers in the environment is related to temperature, and its parameters are very important for the calculation of thermal stress, so the friction coefficient measuring instrument under the environment It is of great significance for testing product performance. At present, most of the instruments used in China to measure the coefficient of friction can only be measured at lower temperatures, and cannot be measured at higher temperatures, and the friction coefficient is measured by the formula of μ=F / f , So the F forward pressure value and the accuracy of the friction force are directly related to the measurement of ...
