Product Description

Product Description

Microcomputer-Controlled Servo Low-Temperature Fracture System for Asphalt Mixtures

It adopts a servo drive system, combined with a high-precision and high-efficiency mechanical transmission system and electronic control technology. It is specially equipped with a low-temperature environment box that can reach as low as -50 degrees Celsius, which is specifically used for the low-temperature freezing break test of mixtures. It is suitable for relevant research institutions in the fields of hydraulics, highways, etc.

Product features

1. The environmental box is equipped with an imported high-efficiency reverse cycle refrigeration unit, a 180mm thick foam insulation layer, and an independent operation touch screen temperature controller. It can achieve a cooling rate of 50°C within 1 hour.

2. The environmental box and the main unit are designed separately, with a rolling mechanism based on rails for movement. It can be removed when not in use.

3. It is equipped with a high-precision LVDT displacement sensor, a circuit and sensitive element separation design, which can prevent drift of the sensor output data caused by environmental temperature.

 4. Based on software closed-loop, the automatic compensation technology for frame deformation is configured, eliminating the influence of low-temperature deformation of the transmission rod on the fixture.

5. A 7-inch true color touch LCD screen is installed on the side of the main unit, which can be used for quick operation during the test.

6. The control cabinet is designed for human body standing operation, with a keyboard and mouse operation platform.

7. The main control computer is a 19-inch Windows industrial tablet computer, with our company's independently developed dedicated freeze fracture test software, which can complete the calculation and display of fracture temperature, fracture strength, and slope of temperature stress curve.

8. A dedicated ultra-low shrinkage coefficient tensile fixture is standardly equipped, meeting the requirements of the specification for specimen size (40*40*220mm). This fixture is made of low shrinkage coefficient Ying steel material, and its shrinkage coefficient meets the requirements of this test without the need for additional calibration.
