Detailed Description
WAW-300B/600B/1000B Computer Control Electrohydraulic Servo Universal Testing Machine Ⅰ. Main functions & features: 1. This machine adopts computer controlled digital broadbrand electrohydraulic servo valve to drive precision hydraulic cylinder to perform automatic control to test force,displacement,deformation in many modes and thus finishes tests of tension,compression and bending.it accords with standard requirements of GB/T228-2002 Method for Tensile Test of Metallic Materials at Room Temperature and GB/T3159-92 Hydraulic Universal Testing Machine.if added with accessories,it can perfom mechanical performance tests for high strength bolt,chain and steel wire etc. 2. Utilizing downsetting hydraulic cylinder,and its power of adjusting test space and transmission mechanism are installed the bottom of machine,stable transimission.its upper and lower jaw bases are open,easy to install specimen and with good stability. 3. Independent hydraulic servo loading system,adopting high precision broadbrand electrohydraulic servo valve to make sure that system is high precision,high efficiency,low noise,fast response.and its independent hydraulic clamping system makes system low noise,smooth operation.during test,specimen is clamped tightly and nonslip. 4. Utilizing computer control,completely realizing three closed loops to test force,displacement,strain. With accurate and reliable test procedure control,data acquisition,processing,analysis(test data including: elasticity modulusE,tension strength Rm,Upper and lower yield points ReH,ReL etc.). Ⅱ.main technical parameters: Spec. WEW-300B WEW-600B WEW-1000B Max.test force(KN) 300 600 1000 Effective measuring range(KN) 6-300 12-600 20-1000 Indicating accuracy (better than indicating value) ±1% ±1% ±1% Max.distance between tensile jaws(mm) 600 650 650 Max.distance between upper and lower pressure plates(mm) 450 450 500 Size of upper and lower pressure plates(mm) Φ160mm Φ160mm Φ160mm Clamping range of round specimen(mm) Φ6-13; Φ13-26 Φ13-26; Φ26-40 Φ13-26; Φ26-40 Clamping range of flat specimen(mm) 0-15 0-15;15-30 0-15;15-30 Max.clamping width of flat specimen(mm) 70 70 70 Main machine(mm) 740×550×2000 740×550×2100 840×580×2200 Console(mm) 2000×500×1000 2000×500×1000 2000×500×1000
