Specifications

1. dynamic display the speed, time and test curve
2. high precision electro-hydraulic digital servo valve for controlling load

1. Usage
"YAW-2000 electro-hydraulic servo compression testing machine UTM, pressure testing machine" construction such as the railroad, road, bridge, port, high-rise etc. This tester is mainly used for the bending and breaking resistant pressure test to the cement, sand, concrete, building material products, and other materials.

2.Test force safety apparatus:
"YAW-2000 electro-hydraulic servo compression testing machine UTM, pressure testing machine" stops when the temperature raises over the set value if the test force is 2%-5% higher than the max. test force of every level, or the output of the transducer reaches to the highest, because of the thermorelay on the electric plate.

3. Charateristics
"YAW-2000 electro-hydraulic servo compression testing machine UTM, pressure testing machine" adopts the high precision electro-hydraulic digital servo valve for controlling the loading with the functions of automatic and manual loading. It finishes the complete test automatically controlled by a micro-computer according to the stress rate and preset curve. It has the function of dynamic displaying the speed, time and test curve.

4. Operating system
The system adopts the high precision digital servo valve. It is with the function of force closed-loop control. It fulfills the equal load rate loading and equal stress rate loading. It is with the high control accuracy and good reliability, fully conformed with the standards of GB, SIO, ASM, and so on. Also the test request of material, such as cement, concrete, etc, especially for the test place of long time continue operating.

5. Security device
Test force safety apparatus: the electric motor stops when the temperature raises over the set value if the test force is 2%-5% higher than the max. test force of every level, or the output of the transducer reaches to the highest, because of the thermorelay on the electric plate.

6. Strucure
This machine consists of two parts, mainframe and control cabinet.
6.1 Mainframe is composed by upper beam, lower beam (base), oil cylinder, piston, upper and lower plates and four upright posts. The upper beam is fixed with a upper bearing plate. Upper and lower plates are rubbed down after being heating processed. There fixed a position line on surface of the lower bearing plate for placing the center of the sample. The lower plate is on the piston with a dustproof cover between them. Oil cylinder and piston, which are fixed at the center of the lower beam are the main parts of the machine. Both are grinded to a certain fit clearance.
6.2 control cabinet, oil pump, high precision electro-hydraulic digital servo valve, oil source, filling and return valve.
Fix the oil pump on the bottom-left of the control cabinet after connected to the electric motor. The oil source is placed on the bottom-right of the control cabinet. The connecting plate is set on the oil box for the digital servo valve. Filling and return valve is fixed in the middle of the top-left of the control cabinet. Test controller is on the top-left of the cabinet. Screen and keyboard are on the top-right, and computer is on the bottom-right. When loading, the high pressure oil enters into the filling valve and digital servo valve or operating button control digital servo valve. It unloads when the oil back to the box.
6.3 test force control system
YAW-2000 digital electric power test control system adopts the high precision digital servo valve. It is with the function of force closed-loop control. It fulfills the equal load rate loading and equal stress rate loading. It is with the high control accuracy and good reliability, fully conformed with the standards of GB, SIO, ASM, and so on. Also the test request of material, such as cement, concrete, etc, especially for the test place of long time continue operating.
