GWA-1000B-type electro-hydraulic servo strand testing machines

bargain

• adopt all-digital closed-loop control system, to achieve power, displacement, deformation of the three closed-loop control requirements can be any combination between control, smooth switching;
• not only to meet GB / T 5224-2003 prestressed concrete strand tensile test requirements, suitable for strand tensile testing, but also to fully meet the GB / T 228-2002 metallic materials at room temperature tensile method requirements, suitable for metal rods, plates, steel and fasteners tensile test;
• light beam using carbon steel, high stiffness, surface polished chrome, beautiful, rust, good;
• master cylinder using gap seals and seal structure Manchester, double-sealed, long-term work to ensure zero leakage;
• displacement sensor withdrawable photoelectric encoder and high accuracy.
