MÁQUINAS AUTOMÁTICAS DE ENSAYO DE COMPRESIÓN DE CEMENTO

The TESTMAK Automatic range of single testing chamber cement compression testing machines have been designed for reliable and consistent testing of mortar samples. These compression testers are in suitable international standards ( EN 196-1, 459-2, 1015-11, 13454- 2; ASTM C 109, C348, C349 and BS 3892-1, 4551-1). Automatic cement compression machine 250 kN is manufactured in terms of its technical properties taking into account client requirements by using suitable accessories. These machines also meet the requirements of CE norms for safety and health of the operator. Compression jigs should be ordered separately.
The TESTMAK automatic cement compression testing machines consist of very rigid two column single or single chamber frames, automatic hydraulic power pack with data acquisition and control system TCM-304.
The TESTMAK automatic cement compression testing machines allow less experienced 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;
Pressing the START button on the control unit.
Automatically saves the test parameters and test results.
Power Pack
M2550/05 Automatic Hydraulic Power Pack, dual stage, controlled by TCM-304 is designed to supply the required oil to the load frames for loading. Very silent power pack can load the specimen between 50 N/sec 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.
Motor
The motor which drives the dual pump is an AC motor, 220 V, 50-60 Hz, 1 phase, 1 hp and 1.1 kW 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 (maximum pressure valve)
• Transducer
• High pressure radial piston pump
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 18 L capacity. Hydraulic motor oil, number 46, must be used.
TCM-304 LCD Graphic Display
The TCM304 LCD Graphic Display is controlled from the front panel, consisting of 240x120 pixels with a high resolution of 65,000 pixels effective resolution of the LCD display and function keys. Two analog channels for the load cell and two digital channels for there is a displacement sensor.
Firmware
The TCM 304 LCD graphic display is controlled using the function keys on the front panel. Two analog channels for the load cell and two digital channels for there is a displacement sensor. Simultaneous load mapping of specific operating conditions, actual load speed and load / time schedule; USB connection to PC; Multi calibration coefficient.
Data collection and PC software
The testing software compression machine is designed for both ASTM, EN and BS STANDARTS compression testing. This software includes controlling the machine, collecting load data and moving, saving them and reports. The compression test of the software samples takes the diameter and height as the input parameter. It automatically calculates the correction factor, coming with respect for the sample size standards. Graphical results and reports can be saved as a MS Excel sheet.
