WAW-D series microcomputer controlled electro-hydraulic servo universal testing machine

Service Hotline:


1. Product introduction

This series of products are mainly used for tensile, compression, bending and other mechanical properties tests of metal materials, and can be used to detect cement, concrete, bricks, tiles, rubber and their products after adding simple auxiliary devices.

The main engine cylinder is a bottom-mounted, six-column, double-space frame structure, which is composed of a fixed beam and a moving beam to form a tensile test space, a compression and bending test space to be formed by a workbench and a moving beam, and a high-performance electro-hydraulic servo valve is controlled by a computer to complete the test of the material, and the feature points are automatically collected and the result data are calculated after the test is completed.


2. Function introduction

1. The control system of this series of products has three control channels of test force, displacement and deformation and five control modes corresponding to test force, stress, displacement, strain and deformation, and the control mode can be switched at will.

2. Constant rate test force, constant rate displacement, constant rate stress, constant rate strain, constant rate deformation test and constant stress, constant test force, constant displacement, constant deformation and constant strain test can be carried out.

3. It has a powerful database and a variety of interface formats for users to choose from, helping users to achieve LAN communication.

4. All specifications of this series of products use built-in automatic hydraulic clamps.
