It can realize the automatic operation of the test process, display the test force value, loading rate change and test curve dynamically, use microcomputer to analyze and process the data, judge a group of test results, and automatically store and print

 Product Feature

●Tester Host
● Host USES integral cast steel frame structure, high strength, good rigidity, design maximum bearing capacity is 2600 kn, to ensure that under the effect of 2000 kn tension frame body extension deformation is less than 0.1 mm.
● Host within the framework of width of 480 mm, so that the installation of various test fixtures, maximum distance of 300 mm between upper and lower pressure plate. The upper and lower pressure plate movement guide and limit switch are installed in the frame of the main engine to ensure the stability and safety of the test operation.
● The preset screw adjusting mechanism adopts rectangular screw with large bearing capacity and high precision. It is driven by sprocket and equipped with clearance nuts to ensure the stability of the machine under stress and the real data of stable loading and unloading.
● With two-way oil cylinders, cylinder piston effective stroke 100 mm, with quick return valve, such rapid adjustment, is advantageous to the different height of sample for rubber and plastic deformation such as larger materials testing, to shorten the test cycle.
● Host using arc floating head clamp mechanism, combined with the framework and precision machining, testing and assembly of cylinder, to ensure that in the load test specimen compression centerline and machine the overall stress axis coaxial, samples to uniform compression.
