Space Adjustment Method: Electric lift

Hydraulic System:

The hydraulic oil in the tank drives the high-pressure pump through the motor and enters the oil circuit. It flows through the one-way valve, high-pressure oil filter, differential pressure valve group, and servo valve before entering the oil cylinder.

The computer sends a control sianal to the servo valve to control the opening and direction of the servo valve. thereby controlling the flow into the cylinder and achieving constant velocity test force control.

Control System:

The system includes digital servo valves, highprecision sensors, controllers and software, with high 

control accuracy and good reliability. Meet GB, ISO, ASTM and other standards test requirements for 

cement, mortar concrete and other materials. 

Function：

1. With force closed loop control function.

2. Able to achieve equal load rate loading or equal stress rate loading.

3. Use microcomputer to realize electronic measurement and automatically complete tests.  

4. The computer automatically calculates the results and prints the report.

5. Test reports can be designed and exported to Excel.  

6. Safety protection device: When the test force exceeds 3% of the maximum test force, overload protection occurs and the oil pump motor shuts down.
