Problems solved by technology

[0003] In related technologies, high-pressure water and compressed air are mainly used to pressurize the interior of the pressure-bearing device. Due to the limitation of the pressurization method, it is difficult for the simulation device to reach a high internal pressure, and the depth of the deep-water environment that can be simulated is limited.

Abstract

The invention provides a pressure environment simulation system and a pressure environment simulation method, and the system comprises a pressure-bearing device which is internally provided with an inner cavity which is used for placing a tested device; a first rodless cavity, a first rod cavity and a first piston are arranged in the first supercharging device, the first piston is arranged in thefirst rod cavity, and the first rodless cavity is communicated with the inner cavity; and the first power device is connected with the first rod cavity. The first power device provides power for the first piston of the first supercharging device, so that the inner cavity of the pressure bearing device reaches the corresponding high pressure, and the pressure environment simulation system can simulate the high-pressure environment. Then the first power device drives the first piston to move from the first rod cavity to the first rodless cavity, at the moment, fluid media preloaded in the firstrodless cavity and the inner cavity are compressed, and the pressure of the first rodless cavity and the pressure of the inner cavity are increased accordingly.

Description

technical field [0001] The invention relates to the technical field of simulating the construction environment, in particular to a pressure environment simulation system and a pressure environment simulation method. Background technique [0002] With the development and utilization of resources such as oil, gas and minerals, more and more equipment needs to work underground, even in areas with very complicated working environments such as the bottom of deep wells. When drilling or tunneling equipment is operating underground or on the seabed, the groundwater or seawater acting on the equipment will exert a certain pressure on the operating equipment, and the pressure will increase with the increase of the operating depth. Therefore, the reliability of working equipment is particularly important for the smooth progress of the project. [0003] In related technologies, high-pressure water and compressed air are mainly used to pressurize the interior of the pressure-bearing de...
