WYW-DS Series Vibration-Free Microcomputer Controlled Electro-Hydraulic Servo Universal Testing Machine

The WYW-DS Series Vibration-Free Microcomputer-Controlled Electro-Hydraulic Servo Universal Testing Machine is a high-rigidity, single-test-space machine developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. With a load capacity ranging from 100 kN to 1,200 kN, it is specifically designed for high-load mechanical performance testing in sectors such as steel structures and civil engineering. The equipment is suitable not only for tensile and bending tests on metal rods, plates, fasteners, pipes, rebar, high-strength bolts, and high-hardness metal materials, but also for compression tests on concrete.

Core Design and Advantages

Patented Vibration-Free Design: The integrated, high-strength structural base features an effective vibration-dampening design, ensuring zero vibration upon specimen fracture during tensile testing; it eliminates the need for a dedicated foundation, significantly saving laboratory space.

High-Rigidity Six-Column Structure: The main unit utilizes a six-column frame design, ensuring stability and testing accuracy under extreme loads.

Intelligent Interaction System:

• Equipped with an extra-large LCD screen and a high-performance industrial touch-screen PC, enhancing the laboratory's professional image.
• Features the unique SmartTest V10.0 operating interface, ensuring smooth system performance and simplifying complex testing procedures.

Enhanced Safety Protection:

• Equipped with a transparent explosion-proof safety screen that ensures operator safety while providing a clear view for monitoring the testing process. 
• The retractable upper crosshead design simplifies equipment transport and installation.

Precision Control and Drive:

• Class 0.5 High-Precision Sensor: The built-in load cell offers exceptional repeatability and long-term stability, achieving Class 0.5 accuracy. 
  
• Quiet Drive System: The hydraulic system is powered by a servo motor and radial piston pump, ensuring ultra-low noise operation, minimal oil temperature rise, and high efficiency, thereby creating a quiet laboratory environment.

Reliable Gripping: Semi-open grips paired with high-strength liners offer superior wear resistance; built-in hydraulic grips ensure a secure hold, effectively preventing specimen slippage during testing.

Frequently Asked Questions (FAQ)

Q1: ​​What is the practical significance of the "vibration-free" technology in the WYW-DS series?
A: Conventional universal testing machines generate violent vibrations at the moment of specimen fracture, which can damage sensors and reduce the equipment's lifespan. This series utilizes an integrated vibration-damping base to absorb energy, achieving "vibration-free" fracture; furthermore, the unit does not require a special foundation for installation, making setup highly convenient.

Q2: Can this machine perform both tensile and compression tests?
A: Yes. It is a multifunctional testing machine; its single-space design allows for flexible execution of various mechanical property tests, such as tensile and bending tests for metals and compression tests for concrete.

Q3: Is the operating software easy to use?
A: The software system is highly user-friendly. The accompanying SmartTest V10.0 software prioritizes simplicity, speed, and convenience; combined with a large touchscreen interface, it allows even beginners to quickly master the operating procedures.

Q4: Does the hydraulic system experience noise or overheating issues during prolonged operation?
A: The equipment employs a servo-motor-driven radial piston pump, characterized by extremely low noise levels and minimal oil temperature rise, ensuring stable and quiet operation even in busy laboratory environments.

Q5: Are the grips durable?
A: The grips feature high-strength liner plates and a semi-open design. They offer strong clamping force (via an integrated hydraulic drive) and exceptional wear resistance, making them suitable for testing high-hardness materials.
