Core-Rock Compression Load Frame
Load Frame is 600 kN Capacity.
The dimensions of the 600 kN Load Frame allow the testing of concrete and rock samples up to its capacity.
The load frame provides the stability needed for accurate and repeatable test results over the years of operation.
The frames are supplied with factory calibration certificate for force transfer stability and the self-alignment of the upper loading platen conforming to EN 12390-4.
Upper Platens/Lower Platens
Upper Platen (with ball seating assembly) Ø 165 mm and Lower Platen Ø 165 mm.
The platens enable the testing of a wide variety of cylinder or similar samples.
• Manufactured from high quality steel, which is then hardened, smoothed and finished.
• The roughness value for the surface texture of the auxiliary platens is ≤ 3.2 µm.
• Ø 165 mm Upper Platen (with ball seating assembly) and Lower Platen have centering rings on the lower platens for proper centering of 100 mm and 150 mm cylinder samples.
Distance Pieces
Distance pieces are used to reduce the amount of vertical clearance between the upper platen and the lower platen. Supplied with Ø 165x25 mm, Ø 165x50 mm and Ø 165x80 mm distance pieces.
Loading Cylinder Assembly & Limit Switch
The Load Frame has a single acting up stroking ram. The diameter of piston changes with regard to the capacity.
The maximum ram stroke is 50 mm, a limit switch is fitted to prevent over travel of the ram which cuts the power to the pump for safety.
At the end of the test process to start a new test the piston returns to default position.
There is a low friction coaxial PTFE seal between the cylinder and the piston fitted to the cylinder.
HYDRAULIC POWER PACK AND DIGITAL DATA ACQUISITION & CONTROL SYSTEM
Hydraulic Power Pack
Automatic Hydraulic Power Pack, dual stage, controlled by digital readout unit is designed to supply the required oil to the load frames for loading.
Controller unit has a simple and compact configuration.
Very silent power pack can load the specimen between 1 kN/sec. to 20 kN/sec, with an accuracy of ±5%. A Rapid approach pump is supplied as standard. Safety valve (maximum pressure valve) is used to avoid machine overloading.
Maximum working pressure of the system is 400 bar.
Dual Stage Pump
The dual stage pump is formed by two groups;
Motor
The motor which drives the dual pumps 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.
Distribution Block
A distribution block is used to control the oil flow direction supplied by the dual stage pump, the following parts are fitted to the distribution block; Solenoid valve, Safety valve (max. pressure valve), High Precision Pressure Transducer, Low pressure gear pump and High pressure radial piston pump.
High Precision Pressure Transducer
The HİRA range of Automatic Machines can be upgraded with option High Precision Pressure Transducer special calibration Class 1 starting from 1% of the full range.
This unique performance enables the machines to be used for a considerable number of applications including:
• Early age(2 or 3 days) compression strength tests
• Flexural and splitting tests by using proper accessories
• Mortar (Cement) compression tests by using proper accessories
• Core Testing
Load Cell
600 kN Load Cell can be used for load measurements instead of High Precision Pressure Transducer.
These property allows high accuracy at very low sample failures. (Class 1 at 6 kN to 600 kN)
The user can choose Load Cell or Transducer in the order stage.
Oil Tank
The tank includes enough oil to fill the mechanism which pushes the ram during the test. The level and oil temperature can be seen on the indicator fitted to the tank. It has 25 L capacity. Hydraulic motor oil, number 46, must be used.
Digital Data Acquisition & Control System
The unit is designed to control the machine and processing of data from load-cells and pressure 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".
Software
Sample, company, laboratory and test values can be entered in the programme.
Load-time graphic, test reports and sample reports can be taken.
Software provides test data, results, and the load-time graphs can be seen at LCD screen.
The Automatic Core-Rock Compression machine can be controlled (Start, Stop commands) by a computer with the software free of charge. This software provides data acquisition and management for compression, tensile and splitting tensile test throughout the test execution. The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information. Therefore, test parameters can be set and details about the test carried out such as client details, test type, specimen type, user info and other information required can be entered and printed out as well as test report and graph.
Software can be performed in Turkish and English.
Test results, graphics and properties of 24 different specimens can be saved in one folder. Old test folders can be reviewed.
User can highlight all 12 different specimen curves in different colors on the graphics.
Frequently used information like name and location of the laboratory, type and dimensions of mostly used specimens are held in memory and can be written automatically by right clicking on information boxes and selecting frequently used text in menu.
User can access any data of previously completed tests and use in his/ her new report since most of the tests have same structure and properties.
Main Features
• Maximum pressure valves to avoid machine overloading
• Piston travel limit switch
• Emergency stop button
• Software controlled maximum load value
• Front and rear transparent durable Plexiglas guards
Testing machines are supplied with EN compression platens as standard. Machines also comply with the ASTM C39 standard when used together with suitable platens.
Tests can be performed by either Digital Readout Unit or on a computer with using free Software.
The Automatic Core-Rock Compression Testing Machine allow inexperienced operators to perform the tests. Once the machine has been switched on and the specimen is positioned and centered by the help of centering apparatus. The only required operations are;
- Setting test parameters, including pace rate (only required when the specimen type is changed).
- Pressing the START button on the control unit
- The machine automatically starts the rapid approach, when the specimen touches the upper platen the rapid approach is ended and starts loading at the pace rate that selected by user and stops once the specimen fails.
- Automatically saves the test parameters and test results.
