Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] Such as figure 1 As shown, after the refrigerating fan 1 passes through the ventilator 2, one way is connected to the upper end of one side of the test chamber 9 through the exhaust duct 6, and the other is connected to the lower end of one side of the test chamber 9 through the air inlet duct 21. The ventilator 2 The air outlet temperature sensor 5 is connected to the air cooling subsystem; or one end of the cooling tower 13 is connected to the inner bulkhead 10 at the upper end of the other side of the test chamber 9 through the chiller 12, the valve and the water inlet pipe 11. , the other end of the cooling tower 13 is accessed from the inner bulkhead 10 at the lower end of the other side of the test chamber 9 through a water pump 14, another valve 15, a water collecting tank 16 and a drain pipe 18, and the water collecting tank 16 is connected with a water c...

Abstract

The invention discloses a temperature control device and control method for a large arm type centrifuge test chamber. After a refrigeration fan passes through a ventilation fan, one path of the refrigeration fan is switched on from the upper end at one side of the test chamber by virtue of an exhaust passage, another path of the refrigeration fan is switched on from the lower side at one side of the test chamber by virtue of an air intake passage, and the ventilation fan is connected with a temperature sensor, thus an air cooling subsystem is formed; or one end of a cooling tower is switched on from the upper end at the other side of the test chamber by virtue of a cooling water machine, a valve and a water inlet pipe, the other end of the cooling tower is switched on from the lower end at the other side of the test chamber by virtue of a water pump, another valve, a water tank and a drainage pipe, and the water tank is connected with a temperature sensor, thus a water cooling subsystem is formed; and the test chamber is internally connected with a temperature sensor. According to the invention, the two subsystems are switched into the test chamber at the same time, and water-air combined cooling aim and effect can be achieved by virtue of a programmable controller; the two systems have the characteristic of independently or combinedly running, thus effect of the temperature control device is the best; and temperature in the test chamber can be regulated, and reliability and accuracy of a centrifuge test can be improved.

Description

technical field [0001] The invention relates to a temperature control method and device, in particular to a temperature control device and a control method for a test chamber of a large-arm centrifuge. Background technique [0002] A geotechnical centrifuge is a large-scale high-speed rotating mechanical device. The centrifugal acceleration generated by the centrifuge is used to simulate the acceleration of gravity, and the centrifugal force field simulates the earth's gravity field. It is an effective method for geotechnical testing to reproduce the self-weight stress of the prototype structure in the model. [0003] The geotechnical arm centrifuge is generally composed of main components such as a turntable, a rotating arm and a hanging basket, among which the rotating arm and the hanging basket are rotating parts. The space where the above components are placed is collectively called the test chamber, which is a cylindrical building with a diameter of 6-20m and a height o...
