HYW-500 Microcomputer control rock triaxial apparatus

Equipment function
HYW-600 Microcomputer control triaxial apparatus，completely in accordance with the provision of GB/T 50266-2013,it can dothe test of Rock triaxial compression test automaticly under computer controlling.And it can show axial test force, confining pressure test the whole process.It also can acquisition, storage, handling, display, test data and test curve immediately.
Composition profile
1. Host 
Host a modular high-rigidity double-thrust frame；
The working oil cylinder is arranged on the upper end of the frame, and the bottom of the test space is arranged in the track, which is convenient for the pressure chamber to move and install. A spherical pressure plate is arranged on the top of the oil cylinder, which can automatically adjust the heart, so that the pressure plate is closely contacted with the end of the compression rod.。
2. Three-axis
Three axis chamber for the realization of the confining pressure of rock.In the pressure chamber, the pressure self balancing technology is used, so that the axial force and the confining pressure can not interfere with each other, and are independent of each other. Made of high strength alloy structure steel, the pressure plate and pressure piston rod is made of bearing steel after heat treatment and precision machining. The pressure chamber is arranged on the movable trolley, and can move along the track, and the loading and unloading sample is convenient.
3. Axial loading system
The hydraulic servo control system, composed of servo circuit system of high-pressure plunger pump, relief valve, precision filter, oil filter, temperature sensors, such as composition and low pressure gear pump the oil filling system two parts combination of axial loading system in the computer under the control of axial as actuator accurate pressure and precise loading. Test oil and servo oil are separated from each other, non pollution, improve the service life.
4. Confining pressure loading system
The high pressure loading system is used to press and protect the three shaft chamber. The system"s working fluid after pressure amplification and the output of the ultra-high pressure oil source, ultra-high pressure oil supply three axis pressure chamber. As lateral pressure (i.e., confining pressure)
5. Rapid filling system
Fast full working medium for axial actuator and three shaft chamber.
6. Rapid drainage system
After the end of the trial chamber triaxial working medium is discharged, in order to dismantle the specimen。
7. Microcomputer measurement and control system
The measuring control system consists of axial force sensor, confining pressure sensor, axial deformation sensor, radial deformation sensor, displacement sensor, digital control device, servo valve and so on.
   
    7.1 has a number of measurement channels, of which 2 channels; one axial and radial deformation of the channel; displacement of 2 channels.
    7.2 measuring high resolution, full range internal changes, inside and outside are not graded.
    7.3 automatic zeroing, automatic calibration, automatic memory function.
    7.4 with constant force, permanent deformation, constant displacement rate, test rates, uniform deformation control function.
    7.5 with overload, overrange, oil plug, oil temperature, specimen protection.
