YAW series microcomputer controlled electro-hydraulic servo pressure testing machine (two columns)

Service Hotline:


1. Product introduction    

This series of products is mainly used for testing the mechanical properties of metal and non-metal components, of which the 600KN pressure testing machine is mainly for aircraft landing gear and mine support testing, and the bending test device can also be used for bending tests on ordinary metals and non-metals. The whole machine is composed of the main engine, hydraulic source, measurement and control system and other parts.

The main engine adopts the single-space frame structure of the oil cylinder lower type, double column and movable beam, and the lower pressure plate of the 2000KN and 5000KN two kinds of testing machines is a trolley structure, which can walk on the track and facilitate the loading and unloading of samples. The upper pressure plate is installed at the lower part of the cross beam and is connected with the movable cross beam by spherical support. The flatness between the platens can be adjusted at any time during the experiment.


2. Function introduction

1. Accurate compression tests can be carried out under different loading rate conditions.

2. It has two measurement channels of test force and displacement and the corresponding test force, stress, displacement and other test parameters for point-by-point measurement, and the loading rate can be controlled at will.

3. Constant rate test force, constant rate stress, constant rate displacement test and constant test force, constant stress and constant displacement test can be carried out.

4. The system has the functions of automatic zero adjustment, automatic calibration, continuous whole process measurement, stepless speed regulation and so on.

5. Automatically collect, process and display test data, and automatically measure various feature points of the tested material; The test software can also be modified according to the testing standards required by the user to measure the required characteristic values.

6. Automatically draw a variety of test curves such as force-displacement, force-time, displacement-time, etc., automatically edit the test report and print it out in a timely manner.

7. It has a powerful database and a variety of interface formats for users to choose from to help users realize LAN communication.
