Characteristics of High Temperature And High Pressure Testing Machine

The key of the high temperature and high pressure testing machine is to simulate the ultra-high pressure and high temperature working natural environment under oil and gas wells, and test the high temperature and compression resistance of mine special tools and experimental instruments. The system is mainly composed of high-pressure vessels, pipeline system and electrical control system. Among them, the pipeline system includes pressure charging system, temperature raising and desuperheating system, auxiliary pneumatic valve system and other subsystems.

The high temperature and high pressure testing machine is divided into four systems as a whole: server test system, high temperature triaxial working pressure chamber and temperature control system, boiler auxiliary discharge and return system and its detection system. High Temperature Triaxial working pressure chamber and temperature control system are the organization of setting coal / rock sample temperature and in-situ stress natural environment at the same time; The discharge and return system of boiler auxiliary equipment is a professional machine and equipment suitable for the installation and disassembly of coal / rock samples in high-temperature triaxial working pressure room; The detection system is used to detect the temperature, load, deformation, occupation rate, acoustic emission and other technical parameters of coal / rock samples in the whole process of the test.

(1) The testing machine is the only high-temperature and high-pressure rock mechanics testing machine published in China at present. It has large bending stiffness and can simulate the bearing capacity of a 10000 meter deep underground rock stratum, including different coupling fields of axial pressure, confining pressure and ground heating temperature.

(2) Sample selection of the testing machine Φ 200  mm × 400  The large sample of MM is 64 times that of the general sample, which can fully reflect the actual situation of the original rock, especially the harm of cracks to the mechanical characteristics of rock.

(3) The confining pressure of the testing machine is filled with loose industrial salt, which is more stable than the popular liquid pressure transmission, without leakage. At the same time, it can be heat-resistant. The higher the temperature, the better the actual effect of pressure transmission.
