LD_300D computer-controlled electro-hydraulic servo universal testing machine
LD_300D computer-controlled electro-hydraulic servo universal testing machine sends control signals to the servo valve through the computer to control the opening and direction of the servo valve, thereby controlling the flow into the cylinder, and realizing the closed-loop control of constant velocity test force and constant velocity displacement. So as to realize the tensile, compression, bending and other mechanical performance tests of metal materials, non-metal materials, product parts, components, structural parts, and standard parts
