BENCH FOR TESTING OF LOADING ARM NODES AND CONTROL SYSTEM FOR TESTING OF LOADING ARM NODES Russian patent published in 2022 - IPC G01M3/28 F01D3/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, in particular to test benches for loading arm nodes, and can be used to conduct a full range of tests of articulated joints of loading arm nodes, except for certification dynamic tests. The bench is a working platform with a fluid and pressure supply system, into which the test layout is installed and fixed on at least one side by means of a bolted connection. At the same time, the platform contains a support with a drive that makes it possible to set loads on the test layout, and the bench itself contains a test control system. The control system for testing the loading arm components contains a drive control unit and a strapping unit for the test layout of the bench and makes it possible to control the supply and release of fluid from the cavity of the test layout, control thermodynamic parameters in the test cavity, control the rotation parameters of the test layout, control the longitudinal, radial and axial loads acting on the test installation, provide signals to the drive system designed for testing the loading arm node in order to ensure load and rotation, to provide signals for the flow of fluid into the cavity of the test layout and the release of fluid from the cavity of the test layout, to create a vacuum in the test layout. For testing hinge joints, the bench can be equipped with a frame with a drive that makes it possible to set rotation, and an auxiliary frame with a counterweight.

EFFECT: simplifying the design and control of the bench, improving the accuracy of results and safety.
