Technical description and scope of use:

1. This machine is mainly used for testing the mechanical properties of rocks, including tensile testing (using Brazilian splitting disc test) and uniaxial pressure testing of soft rocks; Rock point load tests can also be completed. Point load tests involve placing rock specimens between two spherical conical pressure plates, applying concentrated loads to the specimens until they fail, and then calculating the point load strength of the rock based on the failure load; Equipped with anti shear tools (variable angle shear fixtures), rock variable angle shear tests can also be completed. This microcomputer controlUniversal rock testing machineIt has multifunctional rock testing equipment that is convenient, economical, and multifunctional scientific testing. It can be used for rock mechanics performance testing in engineering units such as coal mines, geology, water engineering, transportation, and construction.

2. The host adopts a high-strength framework structure, with a compact overall structure and reasonable layout The control unit adopts an AC servo speed regulation system to control high-precision and high-frequency AC servo motors, drive precision low-noise reducers, and drive precision ball screw pairs for testing. It can achieve a wide range of adjustment of testing speed (0.2-50mm/min), and the testing process is smooth. The experimental data can be accessed freely, and reanalysis of data and curves can be achieved. Local magnification and editing of data, samples, environment, and testing conditions can be performed, and complete experimental reports and curves can be printed out.

3. This series of products fully comply with GB/T16491-2008《Electronic universal testing machineय की मांभर JJF 1103 - 2003 यों की मौत के; JJF <NUM>#2 - <NUM>#3Universal Testing MachineEvaluation of Computer Data Acquisition System ", JJG139-1999" Tensile, Pressure and Universaltesting machineAccording to the requirements of the "Verification Regulations", rock tensile strength (Brazilian splitting), rock compressive strength, rock point load, shear strength (variable angle shear) and other tests can be completed in accordance with the requirements of standards such as GB/T50266-2013 "Test Methods for Engineering Rock Masses".
