产品简介

Bjsc-w300kn microcomputer controlled steel strand relaxation testing machine is designed according to GB/T 5224-2003 "steel strand of prestressed concrete", GB/T 10120-1996 "metal stress relaxation test method".The design of the main engine and auxiliary equipment of steel strand relaxation test machine draws on advanced technology at home and abroad, with beautiful appearance, convenient operation and reliable performance.Computer system by digital controller, the rotational speed control system control servo motor, the moving jaw, driven by gear system slowdown after complete the test, no pollution, low noise, stable and reliable.

执行标准

GB/T 5224-2003 "steel strand for prestressed concrete"

GB/T 10120-1996 "metal stress relaxation test method".


功能特点

1, the microcomputer control of steel strand relaxation testing machine adopts horizontal structure, beam through double support and workbench space of tensile testing, dynamic driving mechanism (by ac servo control motor, deceleration machine, screw pair) installed at one end of the table, the load around screw drive the jaw movement, so as to realize the sample loading.The testing machine has high stiffness to ensure the accuracy of the test results.

2, USES the lenovo brand computers, absorbing foreign advanced testing machine testing machine company control technology, according to the national standard GB/T5224-2003 prestressed concrete steel strand, GB/T10120-1996 "metal stress relaxation test method" to the requirements of the relevant test, according to the setting of test parameters, automated test process control, data acquisition, display and save (main parameters: the test force, relaxation, relaxation rate or logarithmic relaxation rate, temperature), after the completion of the test to analyze the data and processing, and print the user requirements of the test curve and test report.

3, microcomputer control of steel strand relaxation testing machine based on computer software Windows98 / Windows, Windows XP platform development, interface aesthetics, easy to operate;The test force and deformation display are displayed by the configuration instrument.Embedded database for data history tracing and networking requirements;The report adopts the template mode operation, the user needs simple training to master, the whole software package is strong, the operation is convenient, the function is comprehensive;Is equipped with standard test procedures, press the keyboard shortcuts, experimental system can be in accordance with the standards in 3-5 minutes will load to the breaking load of steel strand 70% or 80%, to keep 1 minutes automatically start recording test data, automatically terminate after arrived at set time test.

4, test curve and theoretical curve fitting of the correlation coefficient of 99% or more, so you can use work 1000 hours, 100 hours of test data of relaxation ratio, and recursive simulations show 1000 hours curve, shortened the time actual experiment.

5. The steel strand relaxation testing machine is equipped with a special sensor for steel wire, which has strong resistance to relaxation and creep, and has a long time force zero drift.
