Introduction: WAW-C series of computer-controlled electro-hydraulic servo universal testing machine is mainly used for metal materials such as tensile, compression, bending, cutting and other tests, adding simple accessories and devices, but also wood, cement, concrete, rubber and products experimenting. The host adopts oil cylinder under the structure, stretching space is located above the host, compression, bending test space is located below the host under the beam and the table, through the lower beam to adjust the test space movement, the lower beam lifting motor, worm, nut Turn to move the beam up and down. The measurement and control system adopts the computer-controlled electro-hydraulic servo measurement and control system independently developed by the company. The sensor force measurement and the microcomputer screen display the test force, deformation and various test curves to realize the constant speed test force, constant velocity deformation, constant velocity displacement, Displacement and other control methods to maintain, in accordance with the GB / T228-2002 automatically calculate a variety of values, and can print a variety of test reports (requires special customization), users can edit their own test report format. Technical Parameters: The maximum test force kN: 300 Test force shows the relative error: ≤ ± 1% of indication Test force measurement range: 2% of the maximum test force to 100% Constant speed stress control range (N / mm2 • S-1): 2 ~ 60 Stress rate error: ≤ ± 5% Constant velocity strain control range: 0.00025 / s ~ 0.0025 / s Strain rate error: ≤ ± 5% Isokinetic displacement control range (mm / min): 0.5 ~ 50 Displacement speed relative error: ≤ ± 5% Clamping method: hydraulic clamping Circle sample holding diameter range mm: Φ10 ~ Φ32 Flat sample holding thickness range mm: 0 ~ 15 Flat specimen holding width mm: 78 Maximum tensile test space mm: 600 Maximum compression test space mm: 500 Control cabinet dimensions mm: 600 × 480 × 960 Host Dimensions mm: 1000 × 600 × 2365 Motor power kW: 3.8 Host quality kg: 2300 Pillar net spacing (mm): 530 Upper and lower plate size mm: Φ125 Curved stick spacing mm: 350 Curved stick width mm: 140 Permissible bending mm: 100 Shear specimen diameter mm: Φ10 Maximum piston stroke mm: 250 Piston maximum moving speed mm / min: about 70 Test space adjustment speed mm / min: about 120
