Computer control 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, concrete,sand and brick.

II  program description
1. Host
Machine as shown in Figure:

2. Hydraulic system
Hydraulic oil tank high pressure pump driven by the motor into the circuit, flows through the check valve, high pressure filter, pressure valve, servo valve, into the cylinder. Computer control signals to the servo valve, the control and direction of the servo valve opening to control the flow into the cylinder to achieve constant test force control.
3. the control system
System, including digital servo valve, high-precision sensors, controllers and software, high control precision and reliability. Meet the GB, ISO, ASTM and other standards on cement, mortar, concrete and other materials testing requirements.
System has the following features:
-Closed-loop control with force;
-Loading rate to achieve such load or other stress rate loading;
-The use of computer realization of electronic measurement, automated test;
-Computer automatically calculates the results and print reports.
-Test reports can be exported to Excel to design
4. safety devices
When the test force exceeds the maximum test force of 3%, the overload protection, oil pump motor stops.
