Machine Introduction

It Measurement and control system adopts high-precision digital servo valve, with force closed-loop control function, can achieve equal load rate loading or equal stress rate loading, high control accuracy, good reliability, the use of microcomputer to achieve electronic measurement, automatic completion of compressive strength test, automatic calculation and print reports, widely used in the construction industry and testing units.

Hydraulic system

The hydraulic oil in the oil tank drives the high pressure pump into the oil circuit through the motor, flows through the check valve, high pressure oil filter, differential pressure valve group, servo valve, and enters 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.

Force measuring system

1.Using high-precision amplifier and A/D converter, the whole process is not divided, real-time display of load, peak value, loading speed and intensite

2.PID closed-loop control strategy is adopted to realize constant speed loading, and the loading curve is displayed in real time

3.Automatic interval timing and continuous testing;

4.Flexible and convenient to query and print test results;
