Electro -Hydraulic Universal Tester

This machine is equipped with four columns, two lead screws and one under cylinder. The testing system adopts a digital control with multiple channels, the stress and strain rate satisfies GB/T228.1-2010 and another tensile test standard of metal material.

Specifications:

Drive system:
The column lifted by the adjustment of the speed reducer, the chain transmission mechanism and the lead screw are driven to realize the stretching and compressing space driven by motor.

Test standards:
GB/T 2611-2007 General Standards for Test Equipment;
JB/T 7406.1-1994 Terminology of Testing Machines-Material Testing Machines;
GB/T 16826-2008 Electro-hydraulic servo universal testing machine;
GB/T 16825.1-2008 Testing of Static Uniaxial Testing Machines-Part 1: Testing And Calibration of Tension and / or Pressure Testing Machine Force Measuring Systems;
GB/T 22066-2008 Evaluation of Computer Data Acquisition System for Static Uniaxial Testing Machine;
JJG 139-1999 Tension, Pressure and Universal Material Testing Machine;
JB/T 6146-2007 Technical specification of extensometer;
JB/T 6147-2007 Testing machine packaging, packaging marks, technical requirements for storage and transportation;
GB/T 228.1-2010 Tensile Test to Mental Material Part I: Room Temperature Test;
GB/T 7314-2005 Compression Test to Metal Material under Room Temperature;
GB/T 232-2010 Bending Test to Metal Material.

Hydraulic System
The hydraulic oil in the tank enters the oil path driven by high pressure pump through the motor, and enters the cylinder by flowing through the high pressure filter, the differential valve group and servo valve. The computer sends signal to servo valve which controls the direction and opening, so as to control the enter flow of oil, and realize the control to test speed, constant velocity displacement.

Control System
1.Tensile, compression, cutting, bending test can be acceptable;
2.Opening editing, importing and exporting of test, standard and test process are acceptable;
3.Test parameters can be edited.
4.Opening EXCEL form, can be edited.
5.Test result can be checked and printed easily;
6.Hierarchical management: Administrator and tester.

Safe Protection
1.Overload protection: when the test force is over 3% of the max force, the oil pumpand motor stop automatically.
2.Limit protection: When the piston rises to the upper limit position, the oil pump and motor stop automatically. When the beam drops to the set position, the reducer stops automatically.
