Hydraulic Universal Testing Machine for Fasteners Mechanical Properties Bolts, Screws and Studs
Product introduction:
Hydraulic Universal Testing Machine for Fastener Mechanical Properties (Bolts, Screws, and Studs) is mainly used for tensile testing of metal materials and components, able to detect mechanical properties such as tensile strength (σb), yield strength (σs), elastic modulus (E), elongation at break (ε), etc. The machine adopts hydraulic wedge clamping.
Hydraulic System:
The motor drives the hydraulic oil in the tank to the high-pressure pump for oil suction, which flows through the check valve, high-pressure oil filter, differential pressure valve set, and servo valve into the oil cylinder. The computer sends control signals to the servo valve, adjusting the opening and direction of the servo valve to control the flow into the cylinder, realizing constant test force and constant displacement control. The oil returns to the tank via the tubing, pressure tubing, and oil return valve.
Standards:
ISO 6892, ISO 6934 BS4449,ASTM C39,ISO75001, ASTM A370, ASTM E4, ASTM E8 and BSEN standards.
