Product Description
The LSZ-1000 microcomputer controlled electro-hydraulic servo rock triaxial testing machine is currently an advanced and fully functional rock testing machine (hereinafter referred to as the testing machine).
The testing machine adopts advanced fully digital measurement and control technology, combined with an electro-hydraulic servo system and a computer, to accurately and perfectly achieve full closed-loop control of three states of test force (stress), deformation (axial strain, radial strain), and displacement (compression rate). Moreover, these three full closed-loop control methods can achieve smooth and impact free transitions during the testing process; At the same time, the entire process of the test is automatically controlled according to the programmed program, and the test status is displayed in real time. The stress-strain curves of the entire process of uniaxial compression and triaxial compression deformation of rock samples are drawn.
The testing machine is mainly used for uniaxial compression testing to determine the uniaxial compressive strength, elastic modulus, tangent modulus, secant modulus, Poisson's ratio, and softening coefficient; Triaxial compression test to determine the triaxial compressive strength, elastic modulus, shear strength, and Poisson's ratio.
Product features:
The testing machine is mainly composed of an integral frame type M-type high stiffness host, a three-axis pressure chamber, a booster, a servo oil source, a filling oil source, a servo valve oil distribution system, and an electrical control cabinet (which is equipped with a fully digital measurement and control device and an electrical drive distribution panel) computer system.
1 Host
The main structure type is an integral frame type, with a stiffness of over 11000kN/mm.
The working oil cylinder is placed in the center of the lower base of the main engine, with tracks arranged on both sides of the oil cylinder. A spherical support centering pressure plate is installed in the middle of the upper crossbeam, which can automatically level within a 360 ° range, making the pressure plate tightly contact the end face of the specimen (or three-axis chamber compression rod) and evenly apply force. Install a crane in the middle of the top surface of the upper crossbeam to facilitate the installation and disassembly of the three-axis pressure chamber.
1.1 The oil cylinder and piston surface are made of ultra precision machining, using a combination of clearance and packing for sealing, with good performance, low friction, and long service life.
1.2 The use of hydraulic sensor force measurement method has no effect on the stiffness of the main engine.
1.3 High stiffness, small deformation, conducive to the full process control of rock testing, and the mapping of stress-strain curves.
2. Self balancing triaxial pressure chamber
The triaxial pressure chamber adopts pressure self balancing technology to ensure that the axial test force and confining pressure do not interfere with each other and are independent of each other. The pressure chamber is made of high-strength alloy structural steel, and various rock sample pressure plates and pressure transmission piston rods are made of bearing steel after heat treatment and precision processing. Multiple electrical lead connections are reserved at the base to facilitate the expansion of testing types (and pore water pressure testing interfaces can be prefabricated according to user requirements, and the structural form of the rock sample pressure plate can be provided as a complete set according to testing requirements). The three-axis pressure chamber is fixed on a mobile car and can move along the track, making it extremely convenient for loading and unloading samples.
