YANRUN WEW-1000B Computer-Controlled Hydraulic Universal Testing Machine

Overview

The YANRUN WEW-1000B is a floor-mounted, computer-controlled hydraulic universal testing machine engineered for high-force static mechanical characterization of metallic, polymeric, composite, and ceramic materials. It operates on the principle of servo-controlled hydraulic actuation, where a high-stability oil pressure system drives the crosshead vertically to apply precisely regulated tensile, compressive, bending, or shear loads. Designed in accordance with ISO 7500-1 (Class 1 accuracy), ASTM E4, and GB/T 228.1–2021 standards, the WEW-1000B delivers traceable force measurement across its full 50–1000 kN range, with dual-level accuracy options (±1% or ±0.5%) validated via certified dead-weight calibration. Its low-profile structural layout—featuring a sub-frame mounted hydraulic cylinder—reduces overall height while maintaining rigidity and minimizing lateral deflection during high-load testing. The system integrates real-time load-displacement-deformation synchronization, enabling compliant stress–strain curve generation for yield strength, ultimate tensile strength, modulus of elasticity, and elongation at break.

Key Features

• Floor-mounted, low-height hydraulic architecture optimized for laboratory space efficiency and operator ergonomics.
• Windows-based control software with dual-user permission hierarchy (Administrator & Tester) supporting role-based access control for GLP/GMP-aligned workflows.
• Open-architecture test method editor: users may define custom test sequences, parameter thresholds, stop conditions, and pass/fail criteria without code modification.
• Native Excel-based reporting engine: fully customizable report templates—including headers, units, statistical summaries, and multi-specimen comparative tables—exportable as .xlsx or PDF.
• Real-time overload protection: automatic shutdown if applied force exceeds 103% of full-scale capacity; integrated stroke limit switch halts piston movement at upper mechanical boundary.
• Hydraulic auto-grip system with dual-range round specimen jaws (Φ13–Φ26 mm and Φ26–Φ40 mm) and flat-specimen clamps (0–15 mm thickness, 75 mm width).
• Modular fixture compatibility: interchangeable compression platens (φ160 mm standard; optional 204×204 mm square), three-point bend assemblies (max 450 mm span), and shear fixtures per ASTM D732.

Sample Compatibility & Compliance

The WEW-1000B accommodates standardized specimens per ISO 6892-1, ASTM E8/E21, ASTM C39, ASTM D695, and GB/T 228.1. Round tensile bars (Φ13–Φ40 mm), flat coupons (up to 15 mm thick × 75 mm wide), cylindrical concrete cores (up to φ150 mm), and beam-type flexure samples (max 450 mm span) are routinely tested. All force transducers are calibrated against NIST-traceable reference standards, and system verification follows ISO 7500-1 procedures. The machine supports audit-ready data integrity through timestamped test logs, electronic signatures, and change history tracking—features aligned with FDA 21 CFR Part 11 requirements when deployed in regulated QC environments.

Software & Data Management

The embedded Windows application provides synchronized acquisition of load (kN), displacement (mm), and extensometer-derived strain (µm/mm) at configurable sampling rates up to 100 Hz. Raw data files (.dat) store unprocessed sensor outputs with metadata (operator ID, date/time, environmental notes). Export functions include CSV for third-party analysis (MATLAB, Python), XML for LIMS integration, and structured PDF reports with embedded graphs and statistical summaries. Audit trails record all parameter modifications, user logins, and calibration events—retained for ≥36 months per internal SOPs. Software updates are delivered via secure HTTPS with SHA-256 signature validation.

Applications

• Tensile testing of structural steel, aluminum alloys, and reinforcing bars per ISO 6892-1 and ASTM A370.
• Compressive strength evaluation of concrete cylinders (ASTM C39), mortar cubes (ASTM C109), and geopolymer composites.
• Flexural property determination of laminated wood, fiber-reinforced polymers, and ceramic tiles using three-point bending (ASTM D790, ISO 178).
• Proof loading and creep monitoring of welded joints and pressure vessel components under sustained load.
• Quality conformance verification in automotive component manufacturing (e.g., suspension arms, chassis brackets) per OEM-specific test protocols.
