1. Usage
This testing machine is used for cement, concrete, rock compressive strength test, the machine has characteristic of stable and reliable operation, high adaptability to the environment, high resolution and high accuracy, etc.
2.Technical Parameter
3.Performance characteristics
Electro-hydraulic pressure testing machine is the force closed-loop control of the electro-hydraulic servo pressure testing machine, with constant stress control and load-retaining function; adopt high-precision full-digital servo valve, fast response, high control accuracy, within the scope of the machine allows,users can arbitrary set loading rate according to the requirements of the test; force measurement system using oil pressure sensor, can fully guarantee accurate and reliable test accuracy.
(A) mechanical process structure:
1. The host adopt cylinder lower-set two-column structure, easy to operate.
2, the upper and lower platen adopt 40Cr quenching materials, light bar use high-performance steel precision system, light bar surface chrome polished, beautiful, rust-proof;
3. Cylinder using a special process, honing processing, gap sealing, sealing strong, long service life;
4. Force measurement system using oil pressure sensor, can fully guarantee the accuracy and reliability of the test accuracy;
5. High-precision full-digital servo valve, high-pressure pump, so the machine run stable;
6. Oil source using steel forming, surface spray treatment, marble table can be placed computers and printers, clean and tidy, space-saving.
(B) control and measurement systems:
   The machine control and measurement system absorbs all kinds of advanced experience of pressure testing machine control, using high-precision full-digital servo closed-loop control and measurement system, to achieve control function of constant load rate loading, constant stress loading, test force remain ,etc . High control precision, good reliability. The system has a multi-layer protection, can achieve the test machine overload, overcurrent, overvoltage, undervoltage, overspeed, limit and other security.
The system is equipped with special monitoring and control software, for the test data statistical and processing. During the test, the computer can real time display the force and time parameters, and the dynamic display of the test curve, and can output the test curve and report.
