YAW-30T microcomputer controlled rock elasticity modulus tes


Product name: YAW-30T microcomputer controlled rock elasticity modulus testing machine
I, Technical specification and scope of application
1. This machine is mainly used for mechanical property tests of rock: uniaxial compression test of rock tensile (using Brazil Split disk for test) soft rock; it can also complete uniaxial compression deformation and compression strength tests of rock, and measure elasticity modulus, Poisson’s ratio, compressive strength and other mechanical parameters of rock. The test instrument is a convenient, economical and quick multi-functional scientific test instrument and it can be used for mechanical property tests of rock by coal mine, geology, water conservancy, traffic, building and outer engineering units.
2. The host uses the high strength frame, the machine structure is compact, rational layout. Control unit adopts AC servo control system, high control precision, high frequency response AC servo motor, driving precision low noise reducer, precision ball screw drive pair test, test speed adjustment (0.2 - 50mm / min), test process is stable and efficient. Test data can access arbitrary, and can realize the analysis of the data and curves of the, local amplification and data test environment, test conditions and editing, and print out the complete test report and curve.
3. This series of products in full compliance with the GB/T16491-2008< electronic universal testing machine >JJF1103-2003< universal testing machine computer data acquisition system evaluation >, the force of the JJG139-1999<, compression and universal testing machine verification regulation >, can be in accordance with the requirements GB/T50266-2013< engineering rock mass test method standard > and so on standard.Completing uniaxial compression strength test of rock.
