product name：WAW-B series Microcomputer controlled electro-hydraulic servo universal testing machine
Product introduction
This series of products for the high strength double space frame structure, the cylinder clearance seal, spherical support underneath type structure, tension and compression distance can be adjusted automatically, manually setting the automatic hydraulic clamp, automatic control mode of the two. The control unit adopts computer and electro-hydraulic servo control system, with stress and strain. Three types of displacement closed-loop control method. The test data can be arbitrary access, then analyze and realize the data and curves, local amplification and data editing, sample, test environment, conditions of programming, can automatically find the stress of materials science performance index, and print the test report and complete curve. This series of products mainly used for metal, non-metallic materials tensile, compression, bending, shearing, peeling, tearing and other mechanical properties test
Technical specification and scope of use
1. this series of products are in full compliance with the requirements of .
2. 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 the test machine 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 Win7 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. artificialrecognition, and then print the results。 Can print different kind of report and curves according to the requirements。Using EXCEL form open, convenient user management; original test record value, report value according to the standard requirements of GB/T228 revision;
3. applicable standards and data processing：
A. users can be customized to meet the national standards or other standard data processing software
B. test procedure can be used to simulate the re analysis of the data.
