Abstract

The invention discloses a radial and circumferential deformation measuring method and a system for a high-temperature and high pressure working cylinder. The radial and circumferential deformation measuring method includes the following steps: sampling marks on the high-temperature and high pressure working cylinder to acquire first information; analyzing the first information to acquire second information; analyzing stress on the high-temperature and high pressure working cylinder to acquire third information; processing the second information and the third information to acquire fourth information; and storing and outputting the second information and the fourth information. The radial and circumferential deformation measuring method and the system for the high-temperature and high pressure working cylinder have the advantages that radial and circumferential deformation measurement on the high-temperature and high pressure working cylinder can be detected in real time, evaluation on the service life of the high-temperature and high pressure working cylinder from radial deformation and circumferential deformation can be carried out sequentially, potential safety hazards when the high-temperature and high pressure working cylinder works can be effectively solved, and accumulated experience and actual use effects can be provided for designers when the designers improve or optimize design of the high-temperature and high pressure working cylinder.

Description

technical field [0001] The invention relates to a high-temperature and high-pressure working cylinder of a high-temperature and ultra-high-pressure thermoisostatic press, in particular to a method and system for measuring radial and circumferential deformation of a high-temperature and high-pressure working cylinder. Background technique [0002] The main body of the high-temperature ultra-high-pressure thermoisostatic press is a high-temperature and high-pressure working cylinder, which is a closed container. When working, the medium oil with a certain temperature is filled into the high-temperature and high-pressure working cylinder to form a mold with a specific temperature and pressure that meets the molding requirements. Working chamber: the maximum temperature of the high-temperature and high-pressure working cylinder is 300°C, and the maximum working pressure is 200MPa. However, the radial and circumferential deformation of the high-temperature and high-pressure worki...
