Steel Tensile universal testing machine HZ-003 adopt oil cylinder mounted under the host, mainly for metals, non-metallic tensile, compression and bending test. Used in metallurgy, construction, light industry, aviation, aerospace, materials, universities, research institutes and other fields.
Down beam go up and down by the use of motor reducer, chain drive mechanism, vice screw drive, to achieve tensile, compression of space to adjust. (Hydraulic System Universal Test Machine HZ-003)
Hydraulic System:
The hydraulic oil in the tank through motor drive high-pressure pump into the oil, flows through check, high pressure oil filters, differential pressure valve set, servo valves, into the oil cylinder.Computer control signals to the servo valve, the control and direction of the servo valve opening to control the flow into the cylinder to achieve constant test force, constant displacement control. Through the tubing, pressure tubing through and through oil return valve to tank.
