Technical specification and scope of use

1.Six the series products are 1 column type (four column, double screw), oil cylinder, double space frame structure, tension and pressure distance can be automatically adjusted, hydraulic automatic clamp, set manual, automatic control system, three kinds of control system. The control unit is composed of computer and electro-hydraulic servo control system. It has two kinds of closed loop control system.

2 this series of products are in full compliance with the requirements of <GB/T2611-2007>, <GB/T16826-2008>, <GB/T228.1-2010>, <GB/T232-1999> and so on.

3 control system:

A. adopts high precision amplifier and 24 bit high precision A/D converter, effective code + 120000, the test force measurement resolution of 1/120000, the measurement range of continuous measurement range, measurement accuracy of better than 1;

B. The displacement measurement resolution of  is 0.0025mm, which is used to measure and control the displacement of the piston;

C. The resolution of the deformation of the test machine is 0.00025mm, which is used to measure and control the deformation of the specimen;

D. use the digital servo valve as the control of the implementation of components, anti pollution ability, can achieve long-term failure free operation;

E. adopts PID control strategy to realize the control mode of constant speed, constant speed, constant velocity, constant velocity stress, etc.;

F. in order to manually, automatic two control test process, the test data of the test machine to complete the screen display, users can according to their own needs to design the test machine of the composite control mode;

G. measurement and control system software can work under the Windows98/2000/XP operating system, using standard database management test data, and provide networking data interface;

H. has the function of test force, peak value, deformation of specimen, displacement of piston, screen display function of test curve, real time display test curve, can choose the coordinates, such as stress, strain, load, load, load, load, time, displacement, time, and so on;

I. can meet the test method of tensile GB/T228-2002< material at room temperature > on the mechanical test and data processing, metal tensile test can automatically calculate the Fel, Feh, Fp, Ft, Fm, Rel, Reh, Rp, Rt, Agt, Z, A, Rm and other parameters, but also on the Fel, Fm etc. artificial recognition, and then print the results. According to the requirements can print different kind of report and curves. Using EXCEL form open, convenient user management; original test record value, report value according to the standard requirements of GB/T228 revision;

4 applicable standards and data processing:

A. users can be customized to meet the national standards or other standard data processing software;

B. The test procedure can be used to simulate the reanalysis of the data
