300kn 600kn 1000kn WAW-B Series Computerized Hydraulic Control Universal Tensile Straction Yield Strength Testing Machine for Steel Rebar
1. Actual Appliance
This machine adopts microcomputer control digital broadband, digital valve drive precision hydraulic cylinder, the test force, displacement and deformation for a variety of automatic control mode, complete the specimen tensile, compression, bending test, accord with national standard GB/T228.1-2010 "metallic materials tensile testing at" requirements and other requirements.His host machine adopts hydraulic cylinder underneath type; Adjustment test space power and transmission device installed at the bottom of the tester is stable; Upper and lower jaw to the full open structure, automatic hydraulic press system, convenient clamping sample, stability is good.Lenovo brand computer, performing the experiment parameters setting, in the process of process control, data acquisition, processing, analysis, storage and display (test data including: material tensile strength, elastic modulus, elongation, yield strength and extension strength, etc.), control and measurement precision and accuracy.
2. Control Parts
Amplifier and 24 high precision AD converter with high precision, efficient code: + 300000; Test force resolution 1/350000.Load is realized by using PID control, constant speed control, speed range: 0.2 to 5% FS/S with functions of load.Displacement is realized by using PID control, constant speed control, speed range: 0.6 to 60 mm/min with displacement function.Strain is realized by using PID control, constant speed control, speed range: 0.00025 / S - 0.0025 / S with functions of strain to keep.
