Electro-hydraulic Servo Universal Testing Machine for Prestressed Steel（Microcomputer Controlled）

Electro-hydraulic Servo Universal Testing Machine for Prestressed Steel(Microcomputer Controlled)

Working principle:

The host adopts six-column frame structure with four columns and two screws, with the upper beam and lower beam forming the stretching space, and the lower beam and workbench forming the compression space. Composed of an electrical controller, servo valve, load sensor, displacement sensor, extensometer, and computer, it forms a closed-loop servo control system that can automatically and precisely control the testing process and automatically measure test parameters such as test force, displacement, deformation, etc.

Price advantage:

We increase our own research and development efforts, built processing center, produce the core parts independently, so we could reduce link costs with the same quality. Our good quality products could save you much more than some other low price but bad quality products. Reducing the failure rate of the machine to reduce the customer's maintenance costs, but also improve the efficiency of the machine, this price with high quality could give customers real benefits.

Features:

High-precision measurement:

Equipped with high-precision load sensors, displacement sensors, and extensometers, etc., it can accurately measure parameters such as force, displacement, and deformation during the testing process. The force value accuracy is typically around ±0.5%.

Multiple control modes:

It offers various control modes including force control, deformation control, and displacement control. During the test, it can smoothly switch between different control modes according to the set program.

Wide speed range:

It can achieve stepless speed regulation from very low to relatively high speeds, meeting the loading rate requirements of different materials and tests. The speed range is generally 0.05 - 200mm/min.

Automatic control and data processing:

The test process is automatically controlled through computer software, which can automatically collect, record, and process test data. It can automatically calculate test results such as specified non-proportional elongation strength, tensile strength, elastic modulus, and elongation, and can display the test curve in real time and print the test report.

Multi-functional testing:

It can not only be used for tensile tests of prestressed concrete steel, but also complete various mechanical property tests such as compression, bending, and shearing of other metals, non-metals, and components by replacing fixtures and other auxiliary tools.

Software System:
The testing software operates on a Windows-based platform, featuring a programmable modular architecture that supports seamless integration of diverse control modes. These include:

Constant-Rate Force Control (CRFC)
Constant-Rate Displacement Control (CRDC)
Force Holding Mode (FH)
Displacement Holding Mode (DH)

This flexibility allows users to configure custom test sequences that adhere to international standards (ISO, ASTM, GB/T) while accommodating non-standard methodologies. The software employs a closed-loop servo control system where the computer sends proportional signals to the servo valve, modulating flow rate and direction to achieve precise hydraulic actuation. Key capabilities include:

Real-time data visualization with multi-curve overlay
Automated parameter calculation (yield strength, modulus, elongation)
Comprehensive data management via encrypted file storage
Dynamic report generation with customizable templates

System security is enforced through role-based access control (RBAC), distinguishing between operators (basic functions), technicians (parameter adjustments), and experts (system configuration). This hierarchical structure ensures both operational flexibility and data integrity.

Standards:
ISO 6892, ISO 6934 BS4449,ASTM C39,ISO75001, ASTM A370, ASTM E4, ASTM E8 and BSEN standards.
