 Digital Flexure Testing Machine & Compression Testing Machine (electro-hydraulic)

I,Introduction 
YAW-300 Electro-hydraulic Flexural and Compression Testing Machine is mainly used for flexural strength test of concrete specimen and compressive strength test of building materials such as cement, sand and brick..

Machine as shown in Figure: 

 Figure I    Appearance Schematic diagram

2 hydraulic system
The oil tank is sucked through the filter pump oil network, after the pipeline to send oil pump valve, when the hand wheel to send off the oil, the role of the oil pressure push the piston, the oil flow back into the tank from the return pipe, When the hand wheel is turned to send the oil, the oil tanks through the tubing into the work, and through the pressure tubing flow back into the tank through the oil return valve.
3 Control System
This machine adopts hydraulic loading, electronic measuring, with a load of figures, loading rate shows the maximum load to maintain, as well as overload protection and power data retention and other functions.  

4 safety devices
When the test force exceeds the maximum test force of 3%, the overload protection, oil pump motor stops.
