Computer-coontrolled electro-hydraulic servo bendi

Computer-coontrolled electro-hydraulic servo bending compression testing machine CTMmainly used in the project construction such as the railroad, road, bridge, port, high-rise etc. it is applicable for the tensile strength resistant test to the concrete, construction parts, building materials etc. it can also be used for the strength test to the metal other non-metallic material, construction parts. The system adopts the high precision digital servo valve. It is with the function of force closed-loop control. It fulfills the equal load rate loading and equal stress rate loading. It is with the high control accuracy and good reliability, fully conformed with the standards of GB, SIO, ASM, and so on. Also the test request of material, such as cement, concrete, etc, especially for the test place of long time continue operating. Test force safety apparatus: the electric motor stops when the temperature raises over the set value if the test force is 2%-5% higher than the max. test force of every level, or the output of the transducer reaches to the highest, because of the thermorelay on the electric plate. compression part: Max. test force 300KN Force range 10 300KN Testing space Φ160×(175 375)mm Piston max. stroke 80mm Readout accuracy ≤±1% Motor power 1.1kW (0.75kW) Machine size 940×400×1460mm Net weight 420Kg Packing dimension 1350×800×1500mm Gross weight 520Kg flexture part: Max. test force 10000N Force range 1000 10000N Testing space 210×200mm Piston max. stroke 50mm
