Static constant loading tester is mainly used to determine the resistance to the axial static constant load of plastic manhole. A constant force is steadily loaded on the axial direction of the manhole for specified time, when test is finished, observing the sample appearance (deformation, collapse, crack or crazing), determine the deformation in axial direction and calculate the deformation ratio of manhole. SYICL is also suitable for ring stiffness test, flattening test, ring softness test of thermoplastic.
Standard: BS EN 13598-1:2003 and the equivalent.

Features

1. Gate-type structure with super high rigidity, test speed can be controlled in a wide range, seamless ball bearing.
2. Imported digital AC servo system has been introduced, piecewise linear correction method ensures high accuracy and stability of system.
3. Bridge structure of load sensors avoids side loading especially for big pipes.
4. Unique type inner diameter measuring system tracks the deformation of inner diameter. It is easy to install sample and carry out measurement.
5. With protection functions of overload, over current, over force as well as over temperature, also multi protection methods have been set in mechanical & electrical part and software system.
6. Module design satisfies customers' requirement on extended function. Compression, bending, Ring sitfiness, Ring flexibility, Flatten, Shear and Creep ratio tests can also be carried out on this tester.
7. The system is highly intellectualized, whole test procedure will be recorded automatically.
