Cement Compression / Flexural Test Machine, Touch Screen
The Automatic Cement Compression and Flexure Machine have been designed for testing the flexure of the mortar prisms 40x40x160 mm and the compression on the 40x40mm pieces of prisms after the flexure test or 50x50 mm and 70,7 mm mortar cubes.
These machines also meet the requirements of CE norms for safety and health of the operator.
Compression and flexure jigs, distance pieces and removable transparent front-rear safety doors (should be factory installed) should be ordered separately.
The Automatic Cement Compression and Flexure Testing Machines allow less experienced operators to perform the tests. The only required operations are;
• Very rigid two column single or double chamber Load Frames,
• Automatic Hydraulic Power Pack,
• Digital data acquisition & control system,
• Upper Platen (with ball seating assembly),
• Lower Platen,
• Loading Cylinder Assembly & Limit Switch for safety,
• Software and Ethernet Cable.
Cement Compression & Flexural Load Frames
15 kN and 250 kN high quality load cells are used on frames to provide high accuracy in load measuring. Both frames are fitted with round platens with ∅ 165 mm and these should be used together with suitable flexure and compression jigs.
Upper Platens
Manufactured from high quality steel which is hardened (more than HRC 53), smoothed and finished.
The roughness value for the surface texture of machine and auxiliary platens are 3,2 µm. the movable design.
Distance Pieces
Due to the modular design of the frames any sample with suitable size, load and pace rate can be test on both chambers by decreasing the distance between platens.
Loading Cylinder Assembly & Limit Switch
All frames have 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.
There is a low friction coaxial PTFE seal between the cylinder and the piston fitted to the cylinder.
HYDRAULIC POWER PACK AND H-TOUCH PRO MAX CONTROL UNIT
Hydraulic Power Pack
Automatic Hydraulic Power Pack, dual stage, controlled by H-Touch Pro Max Control 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 0,05 to 2.4 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.
Dual Stage Pump
The dual stage pump is formed by two groups;
1. Low pressure gear pump
2. High pressure radial piston pump
On the dual stage pump, a high delivery, low pressure gear pump is used for rapid approach, while a low delivery, high pressure radial piston pump is used for test execution. The rapid approach facility shortens the time interval from piston start until the upper platen touches to the specimen. This excellent feature helps to save a lot of time when a large number of specimens are going to be tested.
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.
Maximum capacity is 400 bar.
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), Transducer, Low pressure gear pump and High pressure radial piston pump.
Load Cell
15 kN and 250 kN high quality load cells are used on frames to provide high accuracy in load measuring.
This property allows high accuracy at very low sample failures. (Class 1 at 2,5 kN to 250 kN)
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 Readout and Control Unit
HİRATEST H-Touch Pro Max Control Unit is designed to control the automatic compressive, flexural and splitting tensile strength tests of construction materials such as concrete, cement mortar, masonry units, paving blocks, roofing tiles by processing of data from load-cells, pressure transducers or displacement transducers which are fitted to the machine.
All the operations of H-Touch Pro Max Control Unit are controlled from the front panel color resistive of TFT-LCD Touchscreen display and function keys.
The unit has easy to use menu options.
It displays all menu option listings simultaneously, allowing the operator to access the required option in a seamless manner to activate the option or enter a numeric value to set the test parameters.
H-Touch PRO Max Control Unit enable simultaneously display machine status, test values, warnings during operation and test graphs such as load-time or load-displacement curves in real time.
Digital graphic display of the unit is able to draw real-time "Load vs. Time" or "Stress vs. Time" graphics.
Main Features of H-Touch Pro Max Control Unit
HİRATEST H-GUI Software has been designed for data acquisition, processing controlling, presentation and reporting compressive, flexural and splitting tensile strength tests of construction materials such as concrete, cement mortar, masonry units, paving blocks, roofing tiles with appropriate Automatic Compression/Flexure Testing Machines and also with a computer.
The Automatic Cement Compression and Flexure Testing Machine can be controlled (Start, Stop commands) by a computer with the HİRATEST H-GUI Software free of charge.
The advanced functions for database management provide an easy navigation of all saved data.
Test parameters can be set and details about the test carried out such as Test Type, Sample Type, Report details, Customer details, Sample details and other information required can be entered in the software.
This information and "Load vs. Time" or "Stress vs. Time" graphics can be seen and printed out on the Test Report.
Following tests can be done with the HİRATEST H-GUI Software;
These machines also meet the requirements of CE norms for safety and health of the operator.
Compression and flexure jigs, distance pieces and removable transparent front-rear safety doors (should be factory installed) should be ordered separately.
The Automatic Cement Compression and Flexure Testing Machines allow less experienced operators to perform the tests. The only required operations are;
- Setting test parameters, including pace rate (only required when the specimen type is changed).
- Choosing the compression or flexure frame by using valve.
- Choosing Capacity of the frame (to call calibration values of the required load cell)
- Use load cell switch frame or compression side (up/down)
- Pressing the START button on the control unit.
- The machine automatically starts the rapid approach; switches the test speed after 1% of the load capacity of the machine and stops once the specimen failure.
- Automatically saves the test parameters and test results.
