SCW-300 Microcomputer Controlled Tensile Stress Relaxation Testing Machine

The SCW-300 Microcomputer Controlled Tensile Stress Relaxation Testing Machine is a professional mechanical testing device developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. It is primarily used to test the tensile stress relaxation mechanical properties of metallic materials (such as steel strand, PC steel rod, steel wire, etc.) at room temperature. This device adopts a horizontal structure design and, combined with microcomputer control technology, provides high-precision data support for materials research and quality inspection.

Core Design and Functional Advantages

High-Rigidity Horizontal Frame:

• The main unit of the equipment adopts a horizontal four-column high-rigidity reaction frame, ensuring structural stability under heavy load testing.
• The loading beam is guided by a smooth rod, exhibiting excellent loading linearity, ensuring a smooth and accurate testing process.

Independently Developed Software System:

• The equipment is equipped with a independently developed testing software package from Yiyu, capable of easily completing testing tasks for different types of materials and meeting different standards.

Extremely High Measurement Accuracy:

• The equipment achieves an accuracy class of 0.5, with the relative error of the test force indication controlled within ±0.5%.
• Constant Resolution Throughout the Testing Process: The force resolution reaches 1/±300,000 of the maximum test force and remains constant throughout the entire testing process.

Compliant with International and Domestic Standards:

• The design strictly adheres to standards such as GB/T 10120 "Metallic Materials - Stress Relaxation Test Method" and ASTM E328 "Materials and Structures - Stress Relaxation Test Method".

Convenient Interaction:

• As shown in the image, the equipment is equipped with an independent computer workbench, facilitating data monitoring and software operation for operators.

Frequently Asked Questions (FAQ)

Q1: ​​What materials does the SCW-300 primarily test?

A: This equipment is mainly used to test the tensile stress relaxation properties of metallic materials at room temperature. Typical applications include steel strands, prestressed concrete steel bars (PC steel bars), and steel wires.

Q2: What are the special features of this equipment's structural design?

A: It adopts a horizontal four-column design. This horizontal structure is more suitable for tensile testing of long metal samples, and the high-rigidity reaction frame and smooth rod guide ensure extremely high loading linearity and stability.

Q3: Does it support automated testing?

A: Yes. Through a microcomputer control system and supporting self-developed software, it can achieve various control modes such as constant velocity displacement or constant velocity load, with a high degree of automation and simple operation.

Q4: Does its installation have special requirements for laboratory power supply?

A: The equipment only requires standard 220V household power (AC 220V±10%) to operate, with a total power consumption of approximately 1.5kW, making it ideal for typical laboratory environments.

Q5: What is the resolution of the measurement data?

A: The equipment has a constant and extremely high resolution throughout the entire testing range. The resolution for both force and deformation reaches 1/300,000 of the maximum value, allowing even minute changes in stress relaxation to be accurately captured.
