Product Description
*Usage and Characteristics*
The measurement and control system adopts high-precision digital servo valve, which has the function of force closed-loop control, which can realize equal load rate loading or equal stress rate loading. High control precision and good reliability, fully meet the requirements of GB/T 17671 “Test method for cement mortar strength (ISO method)”,Using microcomputer to realize electronic measurement, automatic completion of compressive strength test, automatic calculation and printing of reports, it is widely used in construction industry and cement production enterprises.
*Advantages*
(1) Hydraulic system
This machine adopts double oil cylinders, with high control precision and measurement precision. The hydraulic oil in the oil tank drives the high-pressure pump into the oil circuit through the motor, flows through the one-way valve, high-pressure oil filter, high-precision digital 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, thereby controlling the flow into the oil cylinder and realizing the control of the constant velocity test force.
(2) Force measuring system
Using high-precision amplifier and A/D converter, the whole process is not classified, and the load, peak value, loading speed and strength are displayed in real time;
Using PID closed-loop control strategy to achieve constant speed loading, real-time display of loading curve
Automatic interval timing and continuous testing;
Query and print test results are flexible and convenient;

(3) Measurement and control system
The control and measurement system absorbs all kinds of advanced experience of current pressure testing machine control, and adopts high-precision full digital servo closed-loop control and measurement system to realize control functions such as equal load rate loading, equal stress rate loading, and test force retention. High control accuracy and reliability. The system has multiple layers of protection functions, which can achieve various safety protections such as overload, overcurrent, overvoltage, undervoltage, overspeed and limit of the testing machine.
