Automatic Compression Test Machine is designed to carry out compression tests on materials like concrete, cement as well as finished products like tiles, bricks, blocks and other relevant materials. The machine can be used for quality control departments, civil test laboratories, engineering colleges and are adeally suitable for on-site testing for quality control and/or laboratories.
To achieve a loading rate or stress loading rate, high control precision and good reliability, the control system adopts a high precision digital servo valve with force closed-loop control function; The realization of microcomputer automatic measurements, automatic compression strength test complete, automatic calculation and report printing, are widely used in constructive industry and detection department.
The hydraulic oil in the tank enters the oil path through the motor, and flows through the one-way valve, the high-pressure oil filter, the pressure difference valve group and the servo valve to enter the oil cylinder. The computer sends out the control signal to the servo valve and controls the opening and direction of the servo valve, so as to control the flow of the cylinder and realize the control of the constant speed test force.
1.Using high precision amplifier and A/D converter, the whole process is not split, and the load, peak,
loading speed and strength are displayed in real time.
2.Using PID closed loop control strategy to realize constant speed loading and display load curve in real time.
3.Automatic interval timing and continuous test; the results of inquiring and printing are flexible and convenient.
Safety Protection Device
When the test force is over 3% of the maximum force, the oil pump stops working for overload protection.
