Microcomputer controlled automatic pressure testing machineYAW-2000
Brief introduction：First, brief introductionYAW-2000 is mainly used for compressive strength
First, brief introduction
YAW-2000 is mainly used for compressive strength test of brick, rock, cement, concrete and other materials. It is also used for compressive performance test of other materials.
Two, scheme description
1, main engine: the whole machine is schematic diagram (in substance).
2, space adjustment mode: electric lifting.
3. Hydraulic system
The hydraulic oil in the tank drives the high-pressure pump into the oil circuit through the motor and flows through the unidirectional valve, the high-pressure oil filter, the pressure differential valve group and the servo valve to the oil cylinder. The computer sends a control signal to the servo valve to control the opening and direction of the servo valve, so as to control the flow into the cylinder and realize the control of the constant speed test force.
4. Control system
The system includes digital servo valve, high precision sensor, controller and software. It has high control precision and good reliability. Meet the requirements of GB, ISO, ASTM and other standards for cement, mortar, concrete and other materials.
The system has the following functions:
L has the function of force closed loop control.
L can achieve equal load rate loading or equal stress rate loading.
L uses microcomputer to realize electronic measurement and automatic completion test.
L computer automatically calculates results and prints reports.
The L test report can be designed and exported to Excel.
5. Safety protection device
When the test force exceeds 3% of the maximum test force, the overload protection and the oil pump motor stop.
Three, main performance and technical indicators:
1. Maximum test power: 2000kN
2. Test accuracy: Level 1.
3, loading speed: 0.3~9.99kN/ sec adjustable.
4, loading speed error: + 5%
5, pressure plate distance: 340mm
6, host size: 400mm * 450mm * 1280mm
7. Host weight: 750KG
8, power supply (three phase 380V):0.75kW
Four, configuration:
1, 200 ton pressure test machine main engine
2. High precision sensor.
3. One pump.
4. One domestic electric motor.
5. Digital servo valve set.
6. A set of measuring and controlling system for microcomputer controlled pressure testing machine.
7. Lenovo computer
8, HP color printer.
9, a set of compression.
