1.Main Function & Characteristics:

1. Using hydraulic loading, electronics measurement force, digital display testing force, load peak, test speed, automatic data processing;
2. Using oil inlet and outlet valves to control hydraulic system, easy to operate. It has attractive appearance and proper height of operation and indicating parts, easy for customers to operate;
3. Equipped with miniprinter, it can print test results. It can make compression tests for various well shutters and other materials;
4. Its main machine uses double columns structure and upper oil cylinder. It has a large working table with dimension of 1200*1400mm, easy to install wellshutter, with good stability;
5. With protections functions of overload, over-current, overvoltage, over-speed, etc.
6. Its reserved interface is used for networking interconnection or computer connection to upgrade of the machine.

3. Main technical parameters of testing machine

Soft Ware Features

♦The machine utilizes a brand PC to control high precision hydraulic servo valve which drives a hydraulic cylinder to realize such operations:

A.Parameters setting,

B.Data acquisition,

C.Processing and analysis,

D.Display and print results,

E.Setting the loading speed arbitrarily,

F.Control of loading rate, hold time, cyclic loading, etc.

♦The machine can be set to automatically stop during the destructive test for HT materials cyclic, deformation and destructive tests for QT materials (specimen breaks).
