Machine Introduction:
Hydraulic universal testing machine adopt oil cylinder mounted under the host, mainly for metals,
non-metallic tensile, compression and bending test.Used in metallurgy, construction, light industry,
aviation, aerospace, materials, universities, research institutes and other fields.Test operations
and data processing in line with GB228-2002 "metal material tensile test method at room temperature" requirements.

Host:
Hydraulic universal testing machine adopt oil cylinder under mounted type host, stretching space
isat the top of host, compression test space is between the at the work table and the crossbar .

Transmission System:
Down beam go up and down by the use of motor reducer, chain drive mechanism, vice screw drive,
to achieve tensile, compression of space to adjust.

Hydraulic System:
The hydraulic oil in the tank through motor drive high-pressure pump into the oil, flows through check,
high pressure oil filters, differential pressure valve set, servo valves, into the oil cylinder.Computer
control signals to the servo valve, the control and direction of the servo valve opening to control the
flow into the cylinder to achieve constant test force, constant displacement control.through the tubing, pressure tubing through and through oil return valve to tank.

Control System:
1. Support for tensile, compression, shear, bending and other tests;
2. Support open editing test, editorial standards and editorial procedures, and to support export import testing, standards
3. Support custom test parameters;
4. Adopt an open statement in the form of EXCEL, to support user-defined report format;
5. Print the query testing results flexibility, support for printing multiple samples, custom sorting print projects;
6. Procedure supports hierarchical management levels (administrator, tester) user management rights;

Safety Protection Device:
a) When the test force more than 3% of the maximum test force, the overload protection, oil pump motor shut down.
b) When the piston rises to the upper limit position, stroke protection, pump motor shut down.

Fixture:
Whole set fextures include:stretch fixture,compression fixture,bending fixture.
