Computer Controlled Relaxation Testing Machine SL series
Product introduction
Microcomputer control relaxation testing machine is prestressed concrete steel wire and PC steel bar and steel strand relaxation testing new equipment. Using computer to control the test process, automatic data acquisition and automatic processing, reduce the labor intensity of the workers, increase the accuracy of the experiment, is the enterprise, Scientific Research Institute of the ideal test equipment. The device is configured with the appropriate attachments can also do other specimen tensile and compression tests.
operative norm
The GB/T5224-2003< prestressed concrete strand.
The GB/T10120-1996< metal stress relaxation test.
The main function of product characteristics
1 The test machine adopts a vertical structure, beam work station by a double column and constitute a tensile test space, power transmission mechanism (by AC servo motor, reducer, screw to form) is installed below the working in Taiwan, loading screw under moves to drive the lower jaw movement, in order to achieve the sample loading; force measuring sensor is installed on the beam and with the upper jaw connection. Testing machine with a very high stiffness, ensure the accuracy of the results of testing machine;
2 The use of industrial control computer, high anti-interference ability, suitable for long-term work.
3 Based on Windows98/Windows2000/WindowsXP platform computer special software to fully absorb the advanced experience of similar foreign products, according to the national standard GB/T5224-2003< prestressed concrete strand >, metal GB/T10120-1996< should stress relaxation test > the relevant requirements of the design, perfect function:
4 The is equipped with standard test procedures, press the shortcut key, the test system can be in accordance with the standard requirements in 5 minutes will be loaded to the steel strand breaking load of 70% or 80%, keep the automatically start recording data within 2 minutes, arrive at the automatic termination of the trial after the set period of time.
5 The correlation coefficient of 3.2 test curve and theoretical fitting reached more than 99%, so it can be used for the calculation of test data of 72 hours 1000 hours of relaxation rate, shorten the experimental time.
6 testing machine with special steel wire sensor, has the very strong strong ability of relaxation and creep resistance and long time by force of zero drift and sensitivity coefficient can be assured in the permitted range.
7 The steel cable anchor with special material special process, long service life, reliable clamping.
