The machine specification:

Electro-hydraulic servo universal material testing machine 600KN can play electro-hydraulic servo automatic control, automatic measurement, data acquisition, display and processing of the experiment result into an role. With housing under the conditions of the oil cylinder host as the platform, configuration precision pump and electro-hydraulic servo valve, servo controller and PC to realize the multichannel closed loop control can complete test process of automatic control, automatic measurement functions. It has good professional, the characteristics of high reliability, easy upgrade and other features. And with the development of the tester measurement and control technology and test standard changing constantly enrich the consummation.

Basis structure and main functions

1.Host: It is equipped with cylinder - mounted host frame. The structure greatly reduces the height of host. And it has convenient transportation, installation,stable performance and reliability. The test bed is drive by motor, chain and lead screw drive, which realizes the adjustment of tension space and the test operation is convenient.

2.Test and control system:combine with electro-hydraulic servo oil source, full digital PC servo controller, electro-hydraulic servo valve, pressure sensor, extensometer for measuring specimen deformation, photoelectric encoder for measuring displacement, PC measurement and control card for testing machine, printer, multi-function test software package, electrical control unit and other parts.

3.Standard electro-hydraulic servo oil source:

1)It is designed, manufactured in accordance with standard modular unit with mature technology for load-adaptive oil inlet throttle speed regulation system, specially used for electro-hydraulic servo universal testing machine.

2)It is chose by mature technical oil pump - motor,  and has reliable quality, stable performance.

3)The load adaptive throttle speed regulating valve developed and produced by ourselves with unique technology, the system pressure is stable, adaptive constant pressure difference flow regulation, no overflow energy consumption, easy to carry out PID closed-loop control.

4)Pipe system: Pipelines, joints and seals are made of groups with stable performance to ensure reliable sealing of hydraulic system and no oil leakage failure.

4.Electrical control cabinet:

1)All the strong current components of the system are concentrated in the strong current control cabinet, which can effectively separate the strong current unit from the weak current unit of measurement and control, so as to ensure the measurement and control system from interference and long-term stable work.

2)Manual operation button is set on the electric control cabinet, including power switch, emergency stop and start and stop of oil source oil pump, etc..

5.Full digital PC servo control system

1)With PC computer as the main part, the system is fully digital PID regulation, equipped with PC clamping servo amplifier, measurement and control software and data acquisition and processing software, which can realize the closed-loop control of test force, sample deformation, piston displacement and smooth switching of control mode.

2)The system consists of three signal conditioning units (test force unit, cylinder piston displacement unit, specimen deformation unit), control signal generator unit, servo valve drive unit, servo oil source control unit, necessary I/O interface, software system and so on.

3)The closed-loop control loop of the system: the measurement sensor (pressure sensor, displacement sensor, deformation extensometer), servo valve, controller (each signal conditioning unit) and servo amplifier together form several closed-loop control loops to realize the closed-loop control functions of the testing force of the testing machine, the displacement of the cylinder piston, and the deformation of the sample. It has many control modes, such as equal rate test force, equal rate oil cylinder displacement, equal rate strain, etc., and can realize smooth switching of control mode, so that the system has greater flexibility.

6.PC - board servo amplifier for tester

1)It is a pluggable PC card board, which is specially designed for testing machine with advanced computer bus control technology, including program-controlled analog amplifier, A/D conversion, digital data acquisition channel, digital data I/O, etc..

2)The special measurement and control card and PC unit into a single card measurement and control system, can be directly connected with the sensor, measurement and control and data acquisition, and make the complex measurement and control and data acquisition system become simple and reliable.

3)Using computer bus technology, directly into the computer expansion slot, full digital circuit, zero adjustment, gain adjustment and so on are realized by software. It is the latest product unit of testing and control technology development of testing machine.

4)Gain programmable cascade amplifier can get different gain magnification

5)The bridge power supply of the sensor shares the same voltage with the reference voltage of A/D chip, and the whole measurement system attenuates year-on-year, realizing the hardware compensation technology of the bridge power supply.

6)The multi-bit A/D conversion satisfies the sensitivity and resolution requirements of the system, and avoids the software frequency doubling method reducing the characteristics of the system.

7.Multifunctional test software package

1)Operating system Windows98/XP/2000 platform, Chinese operation interface(can upgrade to German version).

2)The computer screen displays the test force, cylinder displacement, loading rate and deformation test data, and draws various test curves such as time-test force/deformation and deformation-test force. Automatic data processing, data processing methods meet the requirements of gb228-2002 standard, such as upper and lower yield points, maximum force points, all kinds of specified non-proportional stress points, all kinds of specified full elongation stress points, etc. At the same time meet the pressure test requirements of the testing machine.
