Steps for using hydraulic universal testing machine, how should hydraulic universal testing machine be used

The single-space hydraulic universal testing machine is mainly used for tensile testing of metal, non-metallic materials or products, and is equipped with appropriate fixtures. The testing machine can also perform various tension and compression tests such as compression, bending, shear, and bolt tensile. At the same time, the testing machine can also obtain performance indicators such as tensile strength, yield strength, specified non-proportional extension strength, elastic modulus of the measured material, and can realize closed-loop control such as equal rate loading, equal rate deformation, equal rate displacement, and equal rate strain. It can conduct process qualification performance verification tests for materials or products.

Hydraulic universal testing machine refers to special equipment used for testing of tensile, compression, bending, shear, etc. of metal materials. The microcomputer screen display hydraulic universal test machine is a high-rigid main machine structure with a cylinder under-mounted high-rigidity main machine. The disc motor drives the turbocharger to move up and down along the screw to adjust the test space. The servo cylinder adopts gap sealing and static pressure support oil film frictionless guidance technology.

Disk selection: Before the test, the maximum load should be estimated and the corresponding measurement range should be selected so that the limit load during damage is controlled between 20 and 80% of the disc at this stage. Specifications and models: FULE4305D, FULE4605D, FULE4106D, FULE4206D

New test: Save the current test results and start a new test. The relative error of the test force display value: ≦±1% of the display value/±0.5% of the display value, 1/500000FS of the deformation amount, three closed-loop control and programming control for constant stress, constant deformation, and constant displacement.

After the test is over, check whether the machine is running normally. First exit the program, turn off the computer, and finally turn off the power supply of the industrial control box. And keep records of the equipment use.

The main cylinder of the single-space hydraulic universal test machine is placed on the upper part, and the main structure is composed of the base, oil cylinder, beam, upper and lower jaws, columns and other components. A sensor and a lower jaw are installed on the base, and the main oil cylinder is installed above the cross beam, which is rigidly connected to the base through two columns. The test space is adjusted by driving the upper jaws to walk in a given space by the stroke of the cylinder piston. The oil cylinder rises and drives the upper jaw upward movement by connecting flange to complete the tensile test, and the oil cylinder descends and pushes the upper jaw downward movement by connecting flange to complete the compression test.

The design is beautiful, convenient to operate and safe, and the jaw lift and lower buttons on the manual operation box are flexible in control, and the test space is easy to adjust and quick; the front-open semi-closed wedge-shaped jaws, the clamping force increases synchronously with the tensile force, and the clamping force is reliable and the cleaning jaws are convenient; the column surface is chrome-plated and polished, which is beautiful and rust-proof; a built-in small oil cylinder is installed at the upper and lower jaws, which is safer, reliable, has a longer life, is oil-free, has a beautiful appearance, and is convenient to operate than the external clamping oil cylinder.

The test software ensures simplicity and versatility of test operations, easy and convenient processing, storage, and transmission of test data, and the test process curve is displayed in real time on the monitor. Tests such as equal rate loading, equal rate deformation, equal rate displacement, equal rate strain can be realized, and segmented control of force, deformation, displacement and strain can be realized in one test, and the controls can be switched smoothly. Test parameters can automatically control the test process and automatically calculate the test results through computer acquisition and software processing. The test curve and test results are displayed in real time by the microcomputer screen, and the test report and test curve are printed by the printer.
