4.3 Main Unit Structure
The machine adopts a dual-space, lower-cylinder design.
Compression Space: Between the test table and lower crosshead, for compression, bending, and shear tests.
Tensile Space: Between the lower and upper crossheads, for tensile tests.
The test space is automatically adjusted by moving the lower crosshead via lead screws. A closed-loop servo control system (controller, servo valve, load sensor, displacement sensor, extensometer, and PC) precisely controls the test process and measures parameters automatically.
The main unit consists of a base, oil cylinder, piston, load cell, lifting motor, reducer, chains, lead screws, test table, columns, crossheads, and hydraulic grips.
Load Cell: High-precision spoke-type sensor for accurate force measurement.
Extensometer: High-precision measurement of sample strain for Rp0.2, ReL, ReH, and Elastic Modulus.
Hydraulic Grips: Open-type, self-locking wedges. Clamping force increases with test load for reliability.
Space Adjustment: Lower crosshead lifting via motor for easy space adjustment.
4.4 Console-type Servo Hydraulic Power Unit (Patent No.: ZL02377174.7)
The hydraulic unit is integrated into a sleek console cabinet with the controller and electrical system, saving space and improving ergonomics.
Valves: Japanese YUKEN solenoid valves and American SUN HYDRAULICS cartridge valves for long life and stability.
Pump: German Eckerle high-pressure gear pump, low noise, max. 25MPa.
Pressure Follow-up Technology: System pressure adjusts automatically with the load, reducing heat and noise. Energy saving up to 60%, no cooling water required.
5. CTS-850 Controller Introduction
Developed specifically for testing machines, it uses high-integration SOC and FPGA chips as the core.
Standard I/O: 4 analog channels (2 load, 2 extensometer), 3 digital channels (displacement), 8DI/8DO.
