Abstract

The invention provides a flexible connection device performance test system and method, and aims to solve the problem of lack and imperfection of test means of flexible connection device performance test, realize simulation and examination of the working state of a flexible connection device on a rack, and perform deep and accurate test research on the use performance and characteristics of the flexible connection device. The device can make up for the deficiency and imperfection of the conventional flexible connection device test means, simulates the rotation and swing of the flexible connection device under the real working condition on the bench test, and collects the rotation torque and swing thrust of the flexible connection device in the movement process and the pressure and temperature of the sealing medium in the flexible connection device. The working performance of the flexible connecting device is evaluated based on the collected working parameters, and the sealing and friction characteristic research and performance evaluation of the flexible connecting device under the actual use condition are achieved.

Description

technical field [0001] The invention relates to a performance testing system and method of a flexible connection device. Background technique [0002] Flexible joints are often used to provide relative rotational and oscillating motion between adjacent parts of a fluid pipeline, in pipelines that convey fluids at high temperature or pressure, while allowing continuous fluid to pass through the pipeline to accommodate expansion and contraction of the pipeline. The flexible connection device is also widely used in the connection of the thermal pipes of the trough solar thermal power plant. The flexible connection device is installed between two heat collection pipes or between the heat collection pipe and the main pipe to realize the sun tracking system. The axial rotation between the heat collection pipe and the fixed pipe, as well as the long heat collection circuit of the solar thermal power generation, the displacement change of the axial pipe due to the high and low tempe...
