One, Technical description and scope of use
1. This machine is mainly used for the determination of rock elastic modulus, Poisson's ratio, compressive strength and other mechanical parameters of the rock uniaxial compressive deformation and compressive strength tests. Highway, railway, bridge, construction, building materials, universities and colleges, Survey Institute industry laboratory of necessary equipment.
2. The host uses the high strength frame, the machine structure is compact, rational layout. Control unit by computer and a hydraulic system. Test data can be arbitrary access, and can realize the analysis of the data and curves of the, local amplification and data, specimen, the environment, the test conditions of re editing, and print out the complete test report and curve.
3. This series of products in full compliance with the GB/T2611-2007< testing machine general technical requirements of universal >JJF1103-2003< test machine computer data acquisition system assessment >JJG139 - 1999< tensile, compression and universal testing machine verification regulation of >GB/T16826-2008< electro hydraulic servo universal testing machine > requirements, in accordance with the requirements GB/T50266-2013< rock test method standard > and so on standard, rock uniaxial compressive deformation and compression strength test.
