Cement Compression Flexure Testing Machine

About Cement Compression Flexure Testing Machine

The Automatic range of single testing chamber and double testing chamber compression and flexure testing machines have been designed for reliable and consistent testing of mortar samples These compression and flexural testers are the results of continuous applications and research studies to upgrade the machines with the latest technologies and conform the current standards 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 and flexure jigs distance pieces and also removable transparent frontrear 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

Once the machine has been switched on and the specimen is positioned and centered by the help of centering apparatus The automatic cement compression and flexure testing machines consist of very rigid two column single or double chamber frames automatic hydraulic power pack with data acquisition and control system

Power Pack

Automatic Hydraulic Power Pack dual stage controlled by control panel is designed to supply the required oil to the load frames for loading Very silent power pack can load the specimen between 50 Nsec to 24 kNsec 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 380 V 5060 Hz 3 phase 1 hp and 075 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

a  Solenoid valve

b  Safety valve maximum pressure valve

c  Transducer

d  Low pressure gear pump

e  High pressure radial piston pump

Dual Stage Pump

The dual stage pump is formed by two groups

Low pressure gear pump

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

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 20 L capacity Hydraulic motor oil number 46 must be used

Dimensions  360 x 380 x 900 mm

Weight approx  80 kg

Power  750 W

Control Unit

Control Unit is designed to control the machine and processing of data from loadcells and pressure transducers which are fitted to the machine All the operations of control unit are controlled from the front panel consisting of a 800x480 pixel 65535 color resistive touch screen display and function keys 2 analogue channels are provided for loadcells or pressure transducers

Control unit has easy to use menu options The control units digital graphic display is able to draw realtime Load vs Time or Stress vs Time graphics
