STANDARDS: EN ISO 15630-1, EN ISO 6892-1, EN ISO 7500-1

Universal Hydraulic Tensile Test Machine (600/1000 kN capacity) is designed to test the ferrous materials for structural values such as yield strength and tensile strength. Apart from tensile tests, Universal Test Machines can also be used for compression tests up to the capacity of the machine.

To Test Core samples up to 100 mm upper platen must be ordered separately.

Maximum security is maintained on 600kN/1000 kN capacity Universal Test Machine by limit switch on the lower grip as well as the safety check valves on the hydraulic system. Hydraulic power unit works silently.

0-40 mm flat and 8-32 mm round samples can be tested on 600 kN capacity frame and 0-40 mm flat and 8-40 mm round samples can be tested on 1000 kN capacity frame with a user friendly hydraulic jaws that comply with standards.

Load cell is used to measure stress. Strain measurement is done by the electronic displacement transducer built in the machine.

Tests can be done fully automatic by digital control unit or computer. Machine complete the test with the set pace rate and turns to start position automatically.

The distance between the grips can be set by motor driven hand set system. The system is controlled by a hand up/down system. With open front hydraulic wedge grips user can load specimen easily.

HYDRAULIC GRIPS

Hydraulically operated grips,completely stop the possibility of sample sliding from the grips enabling for correct and definite strain measurements.Hydraulic grips are very safe and user friendly.

The hydraulic grips has an independent hydraulic power unit with a working pressure of 400 bars.

600 kN capacity Machine is supplied with 8-32 mm round samples grip set and 1000 kN capacity Machine is supplied with 8-40 mm round samples grip set.

Jaw faces for flat samples should be ordered separately.

HYDRAULIC POWER PACK AND DIGITAL DATA ACQUISITION & CONTROL SYSTEM

Hydraulic Power Pack

Hydraulic Power Unit is designed to control the machine and processing of data from load-cell and displacement transducers which are fitted to the machine.
Controller unit has a simple and compact configuration.

Very silent power pack can load the specimen between 2mm/min - 18mm/min with an accuracy of ±5%. Safety valve (maximum pressure valve) is used to avoid machine overloading.

All the operations of Graphic Display are controlled from the front LCD display and function keys 2 analogue channels are provided for load-cells and displacement transducers.

It has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seemless manner to activate the option or enter a numeric value to set the test parameters.

The digital graphic display is able to draw stress vs. strain graph.

Dual Pumps

The dual pumps are formed by two groups;
Grip pump with dual stage pump
Piston pump to make tensile and compression tests
HİRA Test HR-B6000&HR-B1000 tensile testing machine consist of two independent pumps working in one oil tank system.
One pump is controlled with digital readout unit with 3 phase controlled with and inverter to make test, other runs with a pedal to supply pressure to the grips. Grip pump has dual stage pump inside. On the dual stage pump, a high delivery, low pressure gear pump is used for rapid approach, for quick gripping the rebar while a low delivery, high pressure radial piston pump is used for 400 bar grip pressure.

Two Motors

The motor which drives the mainpump in an AC motor and it is controlled by motor inverter.The variation in the oil flow is executed with the variation of the rotation speed of the motor.

The motor which drives the grip pump in an AC motor and it is controlled by a manual pedal. The maximum pressure of the grips can be monitored by a 0-600 bar manometer fitted to the end of the pipe of upper and lower grip connection.

Two Distribution Blocks

Two distribution blocks are used to control the oil flow direction supplied by the pumps, the following parts are fitted to the distribution block; Solenoid valve, Safety valve (max. pressure valve), Transducer and High pressure radial piston pump for main pump to make the test and Solenoid valve, Safety valve (max. pressure valve), low pressure gear pump and High pressure radial piston pump for grip pump.

Digital Data Acquisition & Control System

The unit is designed to control the machine and processing of data from load-cells and displacement transducers which are fitted to the machine.

All the operations of the unit is controlled from the front panel consisting of a LCD display and function keys.

The unit has easy to use menu options.

Digital graphic display unit loading rate of the time of Testing and load values can be monitored.

Digital graphic display is able to draw real-time "Load vs. Time".
