Core Functional Features
Precise Constant Stress Automatic Loading System: Adopts closed-loop servo constant-stress control, automatically maintain constant loading force rate as per standard requirements, no manual adjustment. Effectively avoid human operation errors, fully meet ISO, ASTM, EN, GB cement compression test standards.
Independent Touch Screen Electronic Control Cabinet: Separate control cabinet design, isolated hydraulic vibration interference. 10-inch industrial touch panel with intuitive operation, real-time display test force, loading speed, deformation curve, automatically record peak compressive strength value.
High Rigid Integrated Loading Frame: Thickened cast steel main frame, anti-deformation structure, stable pressure bearing without frame deflection during full-load testing, guarantee long-term test data repeatability and accuracy.
Full Automatic Test Cycle: One-click start test: automatic loading → automatic peak value capture → automatic unloading after specimen crushing → data auto-save. No manual intervention during the whole test process, greatly improve lab testing efficiency.
High Precision Sensing Module: High-stability pressure sensor with 0.5 grade test accuracy, small measurement error, strong anti-interference under factory complex environment. Thousands of test data can be stored locally for traceability.
Safe & Humanized Design: Built-in overload protection, overpressure automatic stop function; transparent safety baffle to block broken specimen fragments; heat dissipation ventilation structure, emergency stop button for quick safety shutdown.
Working Principle
1. Sample placement: Put standard cement/concrete test block in the center of the upper and lower pressure bearing plates of the main machine.
2. Parameter setup: On touch screen cabinet, select corresponding material test standard, set standard constant stress loading speed.
3. Constant-stress servo loading: Electronic control system sends real-time signals to servo hydraulic unit, continuously adjust hydraulic oil output to keep stable constant loading speed on the specimen.
4. Real-time data acquisition: Pressure sensor continuously collect compression force data, system synchronously draw force-time compression curve.
5. Auto stop & data output: When specimen breaks, machine automatically stops loading and records the maximum compressive strength value. Support export PDF/Excel test reports for printing and archiving.
