اختبار سير العمل & التطبيقات المستهدفة
سير عمل الاختبار الموحد:
- Measure specimen length and wall thickness, then center the pipe specimen horizontally beneath the 1000 × 400 mm rigid compression plate.
- Position the internal diameter extensometer within the pipe bore (covering 180 مم ل 1500 mm inner diameters) to directly track vertical inner wall displacement.
- Set the crossbeam test speed on the computer interface in accordance with ISO 9969 or ASTM D2412 standards.
- Initiate loading; the dual 100kN spoke sensors measure high compressive force, while the inner extensometer monitors target inner-diameter deflection.
- The control software records real-time stress-strain curves, calculates ring stiffness (kN/m²), and exports official test reports.
تطبيقات العملاء المستهدفة:
- Thick-walled HDPE double-wall corrugated, steel-belt reinforced, and PP underground sewerage pipe manufacturers.
- Glass-fiber-reinforced plastic (GRP/FRP) mortar pipeline production lines.
- Large-diameter municipal drainage pipe quality inspection centers.
- Civil engineering materials laboratories and university structural research institutes.
100kN Ring Stiffness Testing Machine FAQ
س1: What is the main advantage of the WD-100H over the 50kN model?
أ: The WD-100H features a higher maximum load capacity of 100kN and an upgraded 2200W servo drive system (weighing ~1500 kg with a 2600 mm height). This allows testing of thicker-walled, steel-belt reinforced, metal-composite, or larger corrugated buried pipes that exceed the force limit of 50kN systems.
Q2: Does the system support long-term continuous creep testing?
أ: نعم. The closed-loop control system and software support continuous creep rate evaluations (1000h/42d tests) under constant load or constant deformation conditions in accordance with ISO and EN standards.
س3: How does the dual 100kN spoke-type sensor arrangement improve accuracy?
أ: Heavy-duty large-diameter pipes can exert uneven reactive force distributions during deflection. Dual 100kN spoke sensors distribute force acquisition across the 1000 × 400 mm plate, neutralizing off-center loading effects and ensuring Class 0.5 measurement accuracy.
