Abstract

The invention relates to an electric high-temperature friction system measuring device, including a test system and a data analysis system; by setting a heating pipeline in the test box, the friction coefficient of petroleum equipment under high-temperature conditions can be simulated, and the test box is controlled by the heating pipeline At the same time, the atmospheric pressure in the box is simulated by the air compressor to meet the measurement of the friction coefficient under multiple working conditions, with high precision and fast efficiency; when the test workpiece a is in contact with the test workpiece b, the tension sensor is in a horizontal state, and the pressure sensor It is in a vertical state; avoiding the angle difference between the tension sensor and the pressure sensor and the test workpiece, resulting in the displayed value being greater than the actual value of the applied force; using an electric cylinder to convert the torque force into a horizontal force for testing, friction The magnitude of the force f, the test value stability of the tension sensor is better, the fluctuation range is small, and the measurement accuracy is higher.

Description

technical field [0001] The invention relates to the field of friction coefficient testing, in particular to an electric high-temperature friction system 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 in high-temperature environments. The friction coefficient between layers is related to temperature, and its parameters are very important for thermal stress calculations. Measuring instrument is of great significance to test the high temperature performance of products. At present, most of the instruments used to measure the friction coefficient in China can only be measured at lower temperatures, and cannot measure the friction coefficient at higher temperatures, and the friction coefficient is measured using the formula μ=F / f , so the accuracy of F positive pressure value and f friction force is directly related to the...
