First, the main purpose
Jinan Shisha WAW-C series microcomputer controlled electro-hydraulic servo universal testing machine is
mainly used for testing mechanical properties of metal materials such as tensile, compression and bending. Adding simple accessories can test cement, concrete, brick, tile, rubber and other Products are tested.
WAW-C series microcomputer controlled electro-hydraulic servo universal testing machine is composed of worm gear and worm-type bottom host and piano-type oil source control cabinet. The tensile space is located above the main unit, and the compression and bending tests are located below the main unit, that is, between the middle beam and the table. The adjustment of the test space is realized by moving the middle beam, and the middle beam is lifted by a worm gear. Computer fully-automatic closed-loop control high-performance electro-hydraulic servo valve completes tensile, compression, bending and other tests on various materials. After the test, the test results such as FM, REH, REL, RPO.2, RP1, RM, and elastic modulus E are automatically taken.
1.Abrasion-resistant lining is added between the jaw base and the jaw clamp plate to prevent the scale from falling during the metal stretching process, which causes the bevel of the jaw base to be scratched, making the clamping process smoother and the addition more reliable.
2. It has a variety of control modes such as constant velocity stress, constant velocity strain, constant velocity displacement, stretching control, program editor, etc. The various control modes can be switched smoothly and arbitrarily during the test.
3. The measurement and control software is based on the Chinese Windows XP operating system platform. It has fast running speed, mild interface, menu prompts, mouse operation, multiple sample information input modes, and can meet the test of different materials. Automatically generate batches of samples that have already entered the same conditions at one time, and can also create condition templates.
4. After the test is completed automatically, the sample information, test data, and test curve are automatically stored.
5. Automatically switch to the appropriate range according to the test force or material deformation to ensure the accuracy of the test data measurement.
6. The test data (test force, displacement, deformation) loading state and test curve are displayed in real-time on the screen during the test.
7. According to actual needs, stress-strain, force-displacement, force-time, displacement-time and other curves can be selected for display, analysis, and printing.
8. It has two modes of automatic and manual analysis of test results. Only the mouse can be used to find relevant corresponding points of test results on the test curve.
9. The user can arbitrarily edit the standard text report format or EXCEL text report format according to the requirements of the testing machine.
10.When the load exceeds 2% -5% of full scale, the automatic overload protection stops.
11.Automatically query all relevant historical records according to sample conditions, test date and test data
12. The software reserves the database interface, which is convenient for local area networking between laboratories and experimental data management.
