Overview
The YANRUN WES-100B Digital Hydraulic Universal Testing Machine is a statically loaded, manually operated hydraulic UTM engineered for routine mechanical property evaluation of metallic, polymeric, and composite materials in quality control, R&D, and academic laboratories. It operates on the principle of controlled hydraulic actuation to apply compressive, tensile, or flexural loads to standardized specimens, with force quantified via high-stability load cell transduction and digital signal processing. Designed with a low-profile, bottom-mounted hydraulic cylinder configuration, the WES-100B minimizes overall equipment height and floor-space requirements—making it suitable for constrained laboratory environments without compromising structural rigidity or load-path alignment. Its fixed-frame architecture ensures consistent load train geometry, contributing to high reproducibility across repeated tests per ASTM E4, ISO 7500-1, and GB/T 228.1 compliance frameworks.
Key Features
- Bottom-mounted hydraulic actuation system delivering stable, pulse-free loading up to 100 kN nominal capacity
- Digital LCD display interface with real-time force readout, intuitive navigation, and immediate access to peak load and displacement values
- High-resolution force measurement with 0.01 kN resolution and ≤ ±1% indication error across 4–100% full-scale range
- Integrated dual-limit protection: mechanical overtravel stops and electronic overload cutoff safeguarding both operator safety and actuator integrity
- Manually actuated wedge-type grips optimized for rapid specimen setup; accommodates round specimens from Φ6 mm to Φ26 mm and flat specimens up to 15 mm thick and 70 mm wide
- Hydraulic power unit designed for minimal maintenance, low noise operation, and long-term pressure stability under cyclic duty
- Customizable machine frame color options to align with facility-wide equipment identification protocols
Sample Compatibility & Compliance
The WES-100B supports standard-compliant testing of metallic rods, bars, plates, and sheet materials per ISO 6892-1 (tensile), ISO 37 (rubber tensile), ASTM A370 (steel products), and GB/T 228.1 (Chinese national standard for metallic materials). Its 550 mm tensile and 380 mm compression test zones accommodate common specimen gauges and support configurations—including direct compression of concrete cylinders (with optional platens) and three-point bending fixtures (available as accessories). All force calibration procedures follow traceable metrological practices aligned with ISO/IEC 17025-accredited reference standards. The system meets CE machinery directive essential health and safety requirements when installed with appropriate guarding and emergency stop circuitry.
Software & Data Management
While the base WES-100B operates via standalone digital panel control, optional PC-based data acquisition modules enable USB or RS232 connectivity for time-synchronized force–displacement curve capture. Exported data comply with CSV and Excel-compatible formats for downstream analysis in MATLAB, Origin, or Minitab. Audit-trail functionality—including user ID logging, test timestamping, and parameter lockout—is available in upgraded firmware versions supporting GLP-aligned documentation workflows. Calibration certificates include uncertainty budgets per ISO/IEC 17025 Annex A.3, and all firmware updates are version-controlled and validated prior to deployment.
Applications
- Tensile strength, yield strength, and elongation-at-break determination for low-to-medium strength steels, aluminum alloys, and engineering plastics
- Compressive strength evaluation of cast iron, sintered metals, and rigid polymer blocks
- Proof load verification of fasteners, weld joints, and structural components during incoming inspection
- Educational demonstration of stress–strain behavior, Hooke’s law validation, and necking onset in undergraduate materials science labs
- Pre-qualification testing of adhesives and bonded assemblies under shear or peel configurations (with fixture adaptation)
FAQ
Is the WES-100B compliant with international calibration standards?
Yes—force measurement is traceable to national metrology institutes via accredited third-party calibration services; certificate includes expanded uncertainty (k=2) per ISO/IEC 17025.
Can the machine be integrated into a LIMS or MES environment?
Native integration is not supported in the base configuration; however, optional serial/USB DAQ modules provide raw data streaming compatible with most industrial SCADA and LIMS middleware via ASCII protocol parsing.
What maintenance intervals are recommended for the hydraulic system?
Hydraulic oil should be replaced every 2,000 operating hours or biannually, whichever occurs first; filter elements require replacement every 1,000 hours; annual verification of seal integrity and cylinder concentricity is advised.
Does the system support automatic yield point detection?
No—the WES-100B is a manually controlled, non-programmable UTM; yield determination requires post-test graphical analysis of the recorded force–displacement curve.
Are extensometers supported?
Not natively; however, the machine features standardized mounting threads (M4) on the crosshead and base for aftermarket clip-on or contactless extensometer attachment, subject to mechanical clearance verification.
