Hydraulic Universal Testing Machine

Hydraulic Universal Testing Machine for the tensile, compression and bending test

WAW PC-controlled Electro-hydraulic Servo Universal Testing Machine

I Function:

WAW Series of PC-controlled Electro-hydraulic Servo Universal Testing Machine is for the stretching, compressing, bending, cutting tests of metal, non-metal and composite materials (rubber, plastic, woven, steel materials, ceramics, etc.) It meets with the requirements of GB/T228-2002, Tensile Testing Method of Metal Materials at Room Temperature. It is widely used in aerospace industry, petrochemical industry, mining establishments, metallurgical enterprises, quality units, research institutes, college labs, etc.

II Features:

This series of testing machines can carry out stretching, compressing, and bending tests on the specimen, controlling automatically the test strength, displacement and deformation in several modes though PC-controlled proportional valve and hydraulic cylinder.

The whole test is accomplished by using keyboard and mouse.

Automatically controlling test, collect data, processing data, draw and print test report and seven types of curls, part of which can be magnified.

Auto zero set, auto calibration, continuous measurement without split speed.

Proper functions of self-check and self-diagnostics.

Various protecting functions, such as over load protection (2%~5%), hydraulic system of over pressure protection, speed control.

Stepless speed control, and easy switchover between various control modes

Data can be saved and curve can be magnified. Various curves can showed during the test for better observation.

Realization of the procedure to run automatically by setting test parameter.

Tests of various low-cycle waves, such as triangular wave, sine wave, square wave, can be carried out according to the users settings.

Test and processing of a set of specimens and data

Hydraulic clamps are controlled by key press to be more reliable.

Inter-laboratory network
