| Abstract: |
| Objective To simulate deep water pressure environment realistically and effectively. Methods A method for re-alizing the constant temperature in the pressure loading process of deepsea pressure test was proposed to simulate the temperature of deepsea pressure environment. A device with the function of pressure transmission and heat insulation for deepsea pressure test was designed, based on the study of structure design, sealability design and thermal conductivity of the bladder. The theoretical analysis and simulation calculations of the device were carried out. Results The device could achieve the basic constant temperature of the liquid for a long time, and had good pressure transmission and heat insulation performance. Conclusion The experimental research is carried out on the established test system to realize a small range of constant liquid temperature under the condition of pressure load synchronization in the deep water pressure environment simulation test. This technology provides technical reserves for related technical research in deep water pressure environmental test. |
