Abstract

The invention discloses a seawater seal circulating device. The seawater seal circulating device comprises a leakage-proof tray, an environmental box, a swing arm, a water suction pump and a circulating seawater box. Seawater is contained in the environmental box, the seawater can circularly flow in the parts such as the environmental box, the water suction pump and the circulating seawater box, and it is guaranteed that in the metal material fatigue test, a sample is always in the flowing seawater environment; in addition, seal design of multiple positions is conducted on the seawater seal circulating device, multiple protective measures are designed, and the situation that seawater leaks to damage an expensive dynamic fatigue testing machine is avoided.

Description

technical field [0001] The present application relates to the technical field of testing mechanical properties of metal materials, in particular to a seawater sealed circulation device. Background technique [0002] Ships and marine structures exposed to seawater will inevitably be corroded by seawater and cause corrosion fatigue. Corrosion fatigue can accelerate crack growth, reduce the fracture toughness of materials, and reduce the critical crack size, which greatly shortens the structural crack formation life and crack growth life, resulting in a significant reduction in the service life of ships and marine structures. In order to estimate the strength reduction of ships and marine structures over time and the service life of structures, it is essential to carry out research on the corrosion fatigue performance of steels used in ships and marine structures. [0003] The national standard GB / T15248-2008 "Metallic Material Axial Equal Amplitude Low Cycle Fatigue Test Meth...
