Waw-B Series Microcomputer Control Electro-Hydraulic Servo Universal Testing Machine

Main uses and introduction:
It can perform tensile, compression, bending, shear, peeling, tearing and low cycle tests on metals, non-metals and components, and meets the requirements of GB/T 228-2010 "Room Temperature Tensile Test Methods for Metallic Materials", ISO and ASTM.
Functional characteristics:
1, the test machine cylinder down, using two columns and two screws, double-space frame structure, with a large stiffness and good stability, fixture clamping mode for the hydraulic automatic clamping, clamping reliable and convenient;
2,Configuration of high toughness protection net, in the test space and the operator between the formation of isolation, can effectively guarantee the safety of the operator;
3, the use of the latest servo pump control technology, the system has low noise, strong anti-pollution ability, long-term trouble-free operation;
4, the use of high-precision amplifiers and 24-bit high-precision A/D converter, the effective internal code ± 200000, test force measurement resolution of 1/200000, if the use of high-precision load cell, can ensure that the maximum test force in the range of 0.4% to 100% of the continuous measurement of the range of non-split, the accuracy of the measurement is better than 1 level;
5,Adopting high-performance proportional servo valve or digital valve group as the control execution element, with strong anti-pollution ability, it can realize long-term trouble-free operation;
6,Adopting PID control strategy to realize three closed-loop control of load, displacement and deformation, and can smoothly switch between the three kinds of control, which can realize the control functions of constant-speed loading, load holding, constant-speed unloading, constant-speed displacement and displacement holding;
7, can easily add or delete a test standard, control steps can be freely edited according to the test requirements;
8, real-time display of the test curve, the curve coordinates can be freely selected, in the same interface can simultaneously display three different curves, the test curve can be locally enlarged display;
9,Communicate with PC through Ethernet communication interface, adopt standard database to manage test data, and provide networking data interface;
10, the use of open EXCEL report form, the user can choose the built-in report or customize the report format;
11, can automatically obtain the maximum force, tensile strength, yield strength, non-proportional elongation strength, modulus of elasticity, elongation after break and other parameters, and can print out a complete test report;
