Reinforcement mechanical connector repeated tensile and compressive performance testing machine

Reinforcement mechanical connector repeated tensile and compressive performance testing machineMainly based on the provisions of JGJ163-2013, JGJ107-2016, and JGJ355-2015 standards, tensile, compressive, biaxial tensile and compressive, fatigue, low cycle fatigue, crack propagation, fracture mechanics, and other tests are conducted on the mechanical connection joints of steel bars.

Measurement control:

1. The system consists of electro-hydraulic servo pump station, independent hydraulic clamping module, fully digital PC servo controller, electro-hydraulic servo valve, pressure sensor, photoelectric displacement sensor, extensometer for measuring specimen deformation, testing machine dedicated measurement and control card, printer, measurement and control software, electrical control cabinet and other units;

2. Standard electro-hydraulic servo oil source:

a、 For the load adaptive oil inlet throttling speed control pump station, mature technology is used to design and manufacture modular units according to standards, specifically designed for use with electro-hydraulic servo universal testing machines;

b、 The configuration adopts a constant pressure differential adaptive speed control valve developed and produced by technology. The system automatically establishes a pressure that is suitable for the load, generates no excess heat, and does not require a cooling device. It is convenient and reliable to use;

c、 Choose imported oil pump (Fujitsu, Japan) with reliable quality and stable performance;

d、 Fully enclosed servo oil tank, equipped with air filtration device, liquid level gauge, etc; The system has a filtering accuracy of 5 μ, fully ensuring that the servo valve operates in a high cleanliness environment;

e、 Adopting mature combination technology of overflow valve, throttle valve, and solenoid valve for high and low pressure switching;

f、 Pipeline system: Stable performance group kits are selected for pipelines, joints, and their seals to ensure reliable sealing of the hydraulic system and prevent oil leakage faults;

g、 Installed inside the control cabinet, with a compact structure and easy operation.
