High temperature and high press water loop environmental fatigue test machine

摘要

The invention is by installing a mechanism for measuring the deformation inside the chamber , strain controlled environment under high temperature and water pressure in carrying out fatigue tests of the method of measuring the amount of change of the gauge length of the specimen from outside the chamber to act as a high-pressure chamber and that measured directly from the inside to improve the reliability of a test result by increasing the measurement accuracy significantly excel , relates to a high-temperature and high-pressure environment fatigue testing machine , ; and equipped with a high temperature vessel (autoclave) to maintain the environment of the pressure , strain measurement mechanism of a jig (jig) for fixing a test piece and the test piece is in the inner chamber the lower part of the structure (lower structure) , and the load cell (loadcell), limit sensor , actuator (actuator) is attached comprises a body (main frame) that can support the entire test device .
