Problems solved by technology

[0002] Existing creep fatigue testing machines are mainly used for tension, compression durability, creep, relaxation tests and low cycle fatigue and creep fatigue tests of metal and non-metallic materials, but in the actual industrial production environment, the parts are in the surrounding Under the action of medium (the most common are gases and liquids), due to a period of chemical changes, electrochemical changes or physical dissolution, damage will occur and corrosion will occur. When performing fatigue tests, due to the time consumed by actual experiments compared with manufacturing The time required for parts to corrode is much shorter, and corrosion is difficult to form, so the existing fatigue test equipment cannot simulate the tensile, compression and creep fatigue tests of parts under corrosion conditions.

Description

technical field [0001] The invention belongs to the field of creep fatigue test equipment, in particular to a creep fatigue test system with sodium automatic circulation under high temperature environment. Background technique [0002] Existing creep fatigue testing machines are mainly used for tension, compression durability, creep, relaxation tests and low cycle fatigue and creep fatigue tests of metal and non-metallic materials, but in the actual industrial production environment, the parts are in the surrounding Under the action of medium (the most common are gases and liquids), due to a period of chemical changes, electrochemical changes or physical dissolution, damage will occur and corrosion will occur. When performing fatigue tests, due to the time consumed by actual experiments compared with manufacturing The time required for parts to corrode is much shorter, and corrosion is difficult to form. Therefore, the existing fatigue test equipment cannot simulate the tens...
