Description

technical field [0001] The present invention relates to the technical field of deep-sea environment simulation devices, in particular to a frame-type ultra-high pressure environment simulation device and test method, specifically to a device capable of efficiently simulating a deep-sea ultra-high pressure environment and realizing temperature simulation and control, mainly for deep-sea science and technology. The test equipment provides pressure test support and an in-situ monitoring simulation platform for deep-sea geological and biological research. Background technique [0002] The influence of hydrostatic pressure must be taken into account in the development and application of deep-sea exploration and delivery instruments and equipment. This requires the use of special pressure test equipment to simulate the deep-sea environment. Various performance index tests such as compressive strength, watertight performance, fatigue resistance or functionality under high pressure ...

[0004] Patent 201410157296.8: Deep sea ultra-high pressure environment simulation and detection device, which discloses an ultra-high pressure, large-volume deep sea high pressure simulation detection device, but the patent fails to realize the function of temperature simulation; patent 201610407281.1: Deep sea high temperature and high pressure environment simulation device, through the A jacket is added outside the pressure cylinder to realize the heating of the outer wall of the cylinder by the temperature-regulating medium, and then transfer the heat through the cylinder wall to the working medium in the cylinder to achieve the purpose of heating the internal working medium. This heating method, Although the structure and operation are relatively simple, the efficiency of temperature adjustment is relatively low, and if it involves simulating ultra-high pressure cylinders, the thickness of the cylinder wall 14 is often relatively large, so if this method is used alone, the temperature adjustment efficiency It will be lower, and even this heating method is not feasible on the pressure cylinder with a relatively large wall thickness. At the same time, using this method will lead to uneven distribution of medium temperature between the middle position inside the pressure cylinder and the vicinity of the cylinder wall
