Brief introduction: Slow tensile crack (constant load) beforehand stress corrosion testing machine is mainly used in testing and research of metal materials in a very slow tensile stress and corrosion medium environment under the dual function of mechanical properties. Can also be used to simulate the constant tensile force parts corrosion in the corrosive environment, for constant load to the crack stress corrosion test, test, research on metal materials in the constant tensile stress and corrosion medium under the dual role of environmental performance. The host machine loading frame adopts the TPHS type double column frame combination structure, stable transmission, responsive, very wide speed range, can not only realize at an extremely slow tensile sample loading speed, but also has faster speed, easy to adjust the test space the clamping piece. The whole machine adopts high precision electronic measurement, mechanical and electrical servo load, digital controller and computer control, with advanced technology, high precision, reliable performance, long stability, etc. Features: 1. It has good man-machine interface, timely according to parameters such as force, displacement, temperature, test time value and the related test curve. 2. Can test data for automatic acquisition of testing machine. 3. Strong image processing function. 4. Have overrun, super range, fault alarm and other security protection function; 5. The system has good maintainability; 6. According to the test cycle set, realize the test of time accumulated. Technical parameters: Most large residual: 10 kn; 30 kn. 50 kn. 100 kn; Test force measuring relative error: better than plus or minus 1% value (in the range of maximum range 1% ~ 100%) Slow stretching speed range: 0.000001 mm/s ~ 0.0001 mm/s stepless adjustable Tensile velocity error: plus or minus 1% (24 hours testing speed relative to the nominal value of the average relative error) Effective work space (the distance between the clamp up and down) : not less than 400 mm Test control mode: force, displacement, time, loading rate, and grading loading, unidirectional cyclic loading. Corrosive medium container: using water bath heating, temperature, environment temperature ~ 55 ℃ Corrosive medium temperature control volatility: plus or minus 2 ℃
