200ton Tensile Test Machine adopt oil cylinder mounted under the host, mainly for metals, non-metallic tensile, compression and bending test.Used in metallurgy, construction, light industry, aviation, aerospace, materials, universities, research institutes and other fields.Test operations and data processing in line with GB228-2002 "metal material tensile test method at room temperature" requirements.

Tensile Test Machine Transmission system:

Down beam go up and down by the use of motor reducer, chain drive mechanism, vice screw drive, to achieve tensile, compression of space to adjust.

Tensile Test Machine Hydraulic System:

The hydraulic oil in the tank through motor drive high-pressure pump into the oil, flows through check, high pressure oil filters, differential pressure valve set, servo valves, into the oil cylinder.Computer control signals to the servo valve, the control and direction of the servo valve opening to control the flow into the cylinder to achieve constant test force, constant displacement control.

Tensile Test Machine Safety protection device:

a)When the test force more than 3% of the Max. test force, the overload protection, oil pump motor shut down.

b)When the piston rises to the upper limit position, stroke protection, pump motor shut down.

Overview of how a hydraulic steel tensile strength test machine typically works:

1. Test Specimen Preparation: The steel specimens are carefully prepared according to specific standards, such as ASTM or ISO, to ensure consistent dimensions and surface conditions.

2. Mounting the Specimen: The test specimen is securely clamped into the grips of the testing machine. The grips typically have serrated surfaces to prevent slippage during testing.

3. Applying the Force: The hydraulic system of the testing machine generates a controlled force. It uses hydraulic cylinders and pistons to apply tension to the specimen. The force is gradually increased until the specimen fractures or reaches the desired testing limit.

4. Measuring Deformation: During the testing process, the machine measures the elongation or deformation of the specimen. This is usually done using an extensometer, which is attached to the specimen and records changes in length.

5. Recording Load and Extension: The testing machine records the load or force applied to the specimen and the corresponding deformation or extension. This data is typically displayed on a digital screen or recorded by a computer software system.

6. Calculating Tensile Strength: The tensile strength of the steel specimen is calculated by dividing the maximum load applied to the specimen by its original cross-sectional area. This provides a measure of the material's resistance to being pulled apart.

7. Fracture Analysis: After the test, the fractured specimen is examined to analyze the mode of failure, such as ductile or brittle fracture. This analysis helps determine the material's suitability for specific applications
