HSW-1000B
Microcomputer-controlled electro-hydraulic servo dynamic rock triaxial instrument
Brief Introduction:
This rock triaxial instrument is developed and manufactured according to the following standards:
SL264-2020: Code for rock tests in water and hydro power projects;
GB/T 50266-2013: Standard for test methods of engineering rock mass;
GB/T23561.9-2009: Methods for determining physical and mechanical properties of coal and rock.
Main Features:
The rock triaxial instrument is mainly composed of high rigidity host, pressure self-balancing triaxial pressure chamber, supercharger, servo hydraulic source, servo valve, air compressor unit, measurement and control system, computer system and other parts.
1. The high-rigidity main engine is a portal frame-type high-rigidity structure. The working oil cylinder is placed in the middle of the lower beam of the frame, and rails are arranged on both sides to facilitate the installation and removal of the triaxial pressure chamber. A spherical pressure plate is installed in the middle of the upper beam of the frame, which can automatically adjust the center so that the pressure plate is in close contact with the end of the compression rod.
2. The pressure self-balancing triaxial pressure chamber adopts pressure self-balancing technology and is made of high-strength alloy structural steel. Each pressure plate and pressure transmission piston rod are made of bearing steel after heat treatment and precision machining. The pressure chamber is placed on the mobile trolley, which can move along the track, and it is convenient to load and unload the sample.
3.
The supercharger is an ultra-high-pressure oil source that amplifies the pressure of the working oil of the system and outputs it. The ultra-high-pressure oil is supplied to the three-axis pressure chamber. As lateral pressure (i.e. confining pressure).
4. The servo servo-hydraulic is composed of the confining pressure booster system and the servo oil circuit system is composed of a high-pressure plunger pump set, an overflow valve, a precision oil filter, a temperature sensor, and a cooler.
5. Drain assembly: used to remove the medium in the pressure chamber.
6. The measurement and control system in the microcomputer-controlled electro-hydraulic servo rock triaxial instrument is composed of axial force sensor, confirming pressure sensor, axial deformation sensor, radial deformation sensor, displacement sensor, all-digital controller, servo valve and other parts.
6.1 There are 12 measurement channels. Among them, there are 2 force channels; 1 axial and radial deformation channel; 2 displacement channels.
6.2 High measurement resolution, change in the whole range, no division between inside and outside
6.3 With automatic zero clearing, calibration, and automatic storage function
6.4 It has the control functions of constant test force, constant deformation, constant displacement, uniform test force rate and uniform deformation rate
6.5 It has protection functions such as overload, over range, oil blockage, over-oil temperature, and specimen fracture.
