3.System introduction
3.1 Test machine host
The machine host adopts the four-column frame cylinder under-type, and the oil source part adopts the piano-table integrated oil source;
The upper and lower pressure plates are made of 40Cr quenching material, the light bar is made of high-performance steel, and the surface of the light bar is chrome-plated and polished, which is beautiful and rust-proof;
Upper platen space adjustment mode: electric lifting;
The oil cylinder adopts special technology, honing processing, gap sealing, strong sealing and long service life;
High-precision all-digital servo valve, imported high-pressure oil pump, low noise and stable operation;
The oil source is formed by steel plate, the surface is spray-coated, and the marble countertop can be placed on the computer and printer, which is clean and tidy and saves space.
3.2 Oil source system
The integrated oil source cabinet is composed of hydraulic pump station, oil source control, host control and computer. It is convenient for operation, maintenance, protection and handling. The measurement and control box, display screen and printer can be placed on the marble countertop, and the layout is neat and tidy, saving space. The oil source system pressure can reach 25Mpa.
The power source adopts imported gear pump to ensure stable system pressure and stable cylinder operation during long-term use. The system design fully considers energy saving, reliability, safety and environmental protection. The oil source system adopts components that meet environmental protection requirements. The noise level during operation is less than 60dB (national standard: less than 75dB).
The whole system adopts servo closed-loop control to monitor load changes in real time. It has the functions of tracking, follow-up, adjustability, etc. It can realize fully automatic and precise control. It is the most advanced technology, the highest quality and the most configured high-grade hydraulic servo control system in the testing machine.
3.3 Measurement and control system
The local 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.
Using the most advanced multi-threading technology to collect data, the rate is fast, the stability is strong, and the sensor data can be automatically subjected to various anti-interference processing, thereby avoiding the defects such as control failure caused by accidental acquisition failure;
With powerful report editing function, users can compile test reports according to their own requirements and output various required results. The data can also be saved in Excel format for easy editing.
Using database management, all test data and curves are automatically saved, and curve amplification, comparison and traversal functions are provided, which provides a high-quality foundation for laboratory networking.
The software is suitable for English Windows platform. The software adopts humanized design, friendly interface and convenient operation;
The software supports a variety of test standards for sintering ordinary brick, cement, concrete, mortar, rock compression. It can display test force and loading speed data in real time, and draw time/test force curve;
The software adopts an open database structure, and can use ACCESS and Excel for experimental database communication. The software should reserve a database interface to facilitate localized network connection with the laboratory, which is convenient for test data management;
After the test, the system can automatically analyze and statistically test the results., and has three modes of automatic test, automatic pressure holding and manual output to analyze the experimental results. Analysis and printing of force-time curves can be performed according to actual needs;
The software should have a result reproduction function that the user can open at any time and reanalyze the historical test data.
