This compression testing machine mainly used for brick, cement, concrete and other material compressive strength testing. Widely used in metallurgy, building materials, space flight and aviation, colleges and universities, R&D institution lines. The test operation and data processing meets standard requirements.
Structure: mainly composed by main unit, oil source and measuring control system.
Hydraulic system: he hydraulic oil in the oil box through the motor to drive the high pressure pump entering into the oil channel, flowing though one way valve, high pressure oil filter, differential pressure valve group,servo valve into the oil cylinder. The computer send out signal to the servo valve to control the servo valve openings and direction, in order to control the flow quantity into the cylinder and realize the constant speed test force control.
The system include the digital servo valve, high precision sensor, controller and software. High control precision, good reliable, meet the test GB、ISO、ASTM and other test standard of cement, mortar, concrete test requirement.
*. Force closed loop control function;
* Can realize constant force rate and stress rate loading
* Adopting computer to realize the electronic test, automatic test;
* Computer automatically calculating result and print report;
