1. Functions and features:
1. The microcomputer screen display hydraulic universal testing machine (bolt tension testing machine ) adopts manual oil return valve control, hydraulic loading, electronic measurement, and computer data automatic processing. It mainly completes the stretching, compression and bending of metal and non-metal materials. test. The upper and lower yield forces can be obtained, and various material mechanical properties such as non-proportional elongation strength, total elongation strength, tensile strength, and elastic modulus can be specified. Add special auxiliary tools for bolts, which can complete the tensile test of various bolts such as long bolts, short bolts, single-thread bolts, double-wire bolts and high-strength bolts (level 12.9); other auxiliary tools can be used to complete the testing of steel wire ropes, welding rods and components Various performance tests can also be used for compression tests of non-metallic materials such as plastics, concrete and cement.
2. The main machine of the testing machine adopts the hydraulic cylinder under-mounted type; the tensile space is located above the main machine, and the compression and bending test space is located between the lower beam of the main machine and the workbench. The power and transmission device for adjusting the test space is installed at the bottom of the lower testing machine, and the transmission is stable; the upper and lower jaw bases are fully open structure, which is convenient for clamping samples, good stability, beautiful appearance, low height, and easy operation. It is suitable for industrial and mining enterprises and scientific research. Ideal testing equipment for units, colleges and universities, engineering quality supervision stations and other departments.
3. The computer is used to complete the test parameter setting, test data and test curve acquisition, processing, analysis, storage and display (including: elastic modulus E, tensile strength, upper and lower yield point and other indicators).
4. Equipped with special software for Windows microcomputer screen display testing machine, it can measure the performance parameters of various materials according to national standards or standards provided by users, and perform statistics and processing of test data, output and print various required test curves and test reports.
5. Adopt the latest control cabinet developed by the company: the oil source, control cabinet and computer desk adopt an integrated design. The oil source, strong electric board, and computer host are installed in the control cabinet.On the control counter are monitors and printers. This not only ensures the stability of the hydraulic system, but also has a good overall effect. The humanized appearance design of the control cabinet console is convenient for operation and novel appearance. The integrated oil source control cabinet can be used for microcomputer screen display universal testing machines with different tonnages from 100kN to 2000kN .
