Abstract

PURPOSE:To prevent fatigue rupture due to the generation of repetitive stress of a testing tank by applying constant static pressure to the testing tank. CONSTITUTION:The pressure in the testing tank 1 is held invariably equal to maximum pressure as to a test by a pressure device 9 and a control board 8. Then, the pressure impressed into a body 2 to be tested is varied according to a set program by switching pressure generated by a pump unit 4 through a selector valve 3 controlled by the operation control board 5. Consequently, specific pressure is applied repeatedly to the body 2 to be tested.

[Prior Art] Parts of submarines, deep-sea diving equipment, etc. are subjected to large water pressure every time they dive (1). There are also devices that are located inside a high-pressure container or the like and receive the high pressure as external pressure. Among these items that are repeatedly subjected to high external pressure, for items that are important or that involve human life, the quality must be completely guaranteed in accordance with the actual conditions of use. Therefore, a normal static pressure test alone is insufficient, and pressure resistance and safety must be guaranteed by repeatedly applying a predetermined external pressure for a predetermined number of repetitions.
