Product name: Electro-hydraulic servo steel wire testing machine
Product model: GWA-D series

Product function: This testing machine is mainly used for tensile, compression, bending, shearing and other tests of metal materials. It can be used for tensile, compression, bending, shearing, flexural and other tests of other types of specimens when equipped with corresponding fixtures.

Based on the standards:
GB/T 2611 General technical requirements for testing machines
GB/T 16826 Electro-hydraulic servo universal testing machine
JJG 1063 Electro-hydraulic servo universal testing machine
GB/T 5224 Steel strand for prestressed concrete
GB/T 228 Metal tensile test method standard
GB/T 228 Metal materials Room temperature tensile test method
GB 1499.2 Steel for reinforced concrete Part 2 Hot-rolled ribbed steel bars
GB 1499.1 Hot-rolled round steel bars for reinforced concrete
JGJ 107 Technical regulations for mechanical connection of steel bars
JGJ/T 27 Standard test methods for steel bar welded joints

Machine structure: The main engine, servo oil source and measurement and control computer are designed in a split type;
Measurement and control system: It is composed of oil tank, servo oil pump, control valve group, sensor, servo controller and control software, computer and other components, with high control accuracy and good reliability;
Servo oil pump: It is composed of servo motor and high-pressure oil pump, with the characteristics of fast response speed, wide speed adjustment range and low noise;
Space adjustment: The trapezoidal screws on both sides are used to achieve the rise and fall through the forward and reverse rotation of the motor, with a simple structure;
Beam structure: Semi-enclosed beam structure, the rigidity is greatly enhanced:
Test accuracy: Main engine structural parts It is processed by precision machining center, servo hydraulic control system distributes flow, and high-precision spoke sensor measures force, ensuring the 0.5 level test accuracy of the whole machine, which is better than the national standard;
Noise: Select brand ultra-quiet oil pump, servo motor control, almost no noise during operation, improving user experience;
Specimen clamping method: hydraulic clamp method is adopted, which is easy to operate;
Safety protection: high-toughness protection net is configured in the pulling and pressing space, which is safe and beautiful;
Equipment maintenance: open beam jaw seat, easy maintenance and operation, and an oil discharge port is provided at the bottom of the equipment to facilitate the replacement of hydraulic oil later;
