Introduction: The machine according to CJ / T3012-1993 "cast iron inspection covers", CJ / T121-2000 "recycled resin composite material inspection covers" and JC889-2001 "steel fiber reinforced concrete inspection covers", GB / T 23857-2009 "inspection covers" Industry or national standards for the design, for the bearing capacity of the well cover test. Its structural performance in full compliance with test specifications. Note: HT material samples only damage test; QT material samples or other composite materials to do the cycle, deformation, failure test. Features: 1, the host uses a high-rigidity structure, to ensure the safety of the test process. 2, loading cylinder on the home, table height 300mm, easy to take and put the cover test pieces. 3, rigid pad and push the end of the ball between the use of the ball hinge connection to ensure full contact between the cover and the reaction force to ensure the authenticity of the measured bearing capacity. 4, Cylinder and piston seal with special materials, to achieve high sealing, low friction, long life effect. 5, using professional testing machine pump motor, low noise, long life. 6, the choice of ultra-fine filter to ensure that the oil system clean to ensure that the implementation of the long-term control of the work components. 7, the computer automatically controls the real-time display of current force, peak, test process information. 8, the test process real-time record test curve, high-speed sampling; 9, data, report processing functions, to provide users with a graphical report for the exclusive layout editing tools, with flexible operation, easy to learn characteristics, can easily print test curves and test values; 10, the control mode has constant speed stress, constant speed test force, test force to maintain control functions and test force, peak, screen display test curve, test curve strong - time curve, control mode smooth conversion. 11, the scene can be based on experimental needs, the user-programming, automatic closed-loop control, loop loading, loading speed, loading waveform (due to the standard loading process is a cyclic waveform loading process) So that the whole process to achieve full automation without human intervention. 12, the software set value automatically cleared system, eliminating the artificial reading error and other factors. 13, with overload protection, automatic unloading or stop the test. 14, destroy the load and other information automatically collect and print the report. Technical Parameters: Maximum test force: 1000KN Effective test space: 1500mm × 1500mm Workbench height: 500mm Force accuracy: ≤ ± 1% (better than 1) Loading speed adjustment range: 0.1 ~ 25KN / s Deformation measurement range: 0 ~ 20mm Deformation measurement accuracy: computer acquisition 0.01mm Piston stroke: 350mm Overload protection point: 3% over full range automatic unloading. Load indication accuracy: 0.1KN Loading method: electro-hydraulic Control mode: microcomputer control and manual stepless speed regulation, with automatic programming function. Loading medium: 68 # anti-wear hydraulic oil Motor power: 1.5KW Voltage: 380V / 220V Host size: 2000mm × 1500mm × 1500mm (length × width × height) Host weight: 3000Kg
