4. The testing machine is suitable for compression and bending strength testing of manhole covers, and can meet relevant professional standards such as CJ/T3012-1993 "Cast Iron Inspection Manhole Cover", CJ/T121-2000 "Recycled Resin Composite Material Inspection Manhole Cover", and JC889-2001 "Steel Fiber Concrete Inspection Manhole Cover".

2, Performance and Characteristics

1. The host adopts a high stiffness structure ... during the experimental process.
2. Lower the loading cylinder for easy access to the manhole cover specimen.
3. The steel cushion block is connected to the piston push out end using a ball joint The contact between the manhole cover and the reaction plate is complete The authenticity of the measured bearing capacity.
4. The oil cylinder and piston are sealed with special materials to achieve high sealing, low friction, and long service life.
5. Adopting professional experimental oil pump motor assembly, low noise and long service life.
6. Choose an ultra precision oil filter Clean the oil system accordingly Control the long-term operation of the executing components.
7. Computer automatic control, real-time display of current force value, peak value, test process information, etc.
8. Real time recording of test curves and high-speed sampling during the experimental process.
9. The data and report processing function provides users with a specialized report editing tool for graphic layout, which has the characteristics of flexible operation and easy learning. It can conveniently print test curves and test values.
10. The control mode has control functions such as constant stress, constant test force, and test force maintenance, as well as screen display functions for test force, peak value, piston displacement, and test curve. The test curve has force time curve, force deformation curve, and deformation time curve, and the control mode smoothly transitions.
11. Users can program on site according to experimental needs, automatically closed-loop control, cyclic loading, loading speed, and loading waveform (as the standard loading process is a cyclic waveform loading process). In short, each indicator step of the national standard can be programmed, making the entire process fully automated without manual intervention.
12. The software is equipped with an automatic reset system for force values, eliminating factors such as human reading errors.
13. Equipped with overload protection, when the force or displacement exceeds the rated theoretical value of the testing machine, it will automatically unload or stop the test.
14. Automatically collect and print reports on the damage load and deformation values.
