Problems solved by technology

Domestic and foreign experts have done a lot of research on the water body prediction of the water-bearing structure in mines, but there is still no relevant system applied to the characteristic test of the temperature field of the water-bearing structure. In actual engineering, water body pressure and water body temperature are easily affected by geological conditions, such as geothermal heat will lead to abnormal rise in water body temperature, etc., affecting the accuracy of the test

Abstract

The invention discloses a constant temperature and constant pressure circulating water automatic control system for fluid-solid coupling model tests, and relates to the technical field of geological condition model tests. The invention includes a water tank, a pressurized pump, a heat exchange device, a pressure sensor, a temperature sensor and a controller. The water tank, the pressurized pump, and the heat exchange device communicate with the built-in water body in the model test frame through a circulating water pipeline to form a closed water circulation loop. The device is connected with the booster pump, heat exchange device, pressure sensor, and temperature sensor to keep the circulating water at constant temperature and constant pressure. The invention can automatically control and adjust the temperature and pressure of the water body, keep the constant temperature and pressure of the water body, and improve the accuracy of the simulation test.

Description

technical field [0001] The invention relates to the technical field of geological condition model tests, in particular to an automatic control system for constant temperature and pressure circulating water used in fluid-solid coupling model tests. Background technique [0002] With the development of our country's social economy and the take-off of transportation, the construction of infrastructure and the development and utilization of space are gradually expanding underground. With the continuous increase in the number of underground engineering construction, the scale is increasing, the scope is expanding, and the difficulty of engineering construction is also increasing. For underground engineering, a prominent feature is that buildings have been under the coupling effects of multiple media such as rock (soil), groundwater and gas for a long time. The research on the mechanism of fluid-solid coupling in underground engineering has become a hot spot. Research methods exp...
