Liquid nitrogen cold shrink assembly box

Liquid nitrogen cold shrink assembly box
1.1 Performance characteristics
1. It has an extremely wide temperature control range, which can meet various needs of users.
2. Adopting a unique balanced temperature regulation method, it can adjust the ideal temperature environment. It has stable and balanced heating, and can achieve high-precision and highly stable temperature control.
3. The control instrument adopts our company's independently developed color touch screen controller.
4. It has a set value that varies with temperature, and can be selected for low or high temperature, with simple operation.
5. The temperature setting inside the test box adopts a keyboard setter, making the setting simple and easy. The instrument has an error correction function when setting the temperature, and after correction, more accurate test conditions can be obtained.
6. Liquid nitrogen refrigeration is used in the refrigeration system.
1.2 Main technical parameter indicators (The following performance indicators are measured after stabilizing for 2 hours without test load)
1.2.1 Temperature performance indicators
Test purpose: Quality inspection, product development, production application, reliability testing
Technical specifications of this freezer
Temperature control range: -196 ℃~room temperature+10 ℃ (temperature range can be customized, up to 500 ℃)
Temperature fluctuation: ≤ ± 0.5 ℃
Temperature uniformity: ± 3 ℃
Cooling rate: ≥ 5-50 ℃/min (cooling rate can be customized according to customer requirements)
Temperature control accuracy: ± 0.01 ℃
1.2.2 Main low-temperature freezer applications:
Low temperature assembly boxes are suitable for the assembly of interference fit parts that contain components (such as planetary frames, torque arms, etc.) without heating or that may cause changes in part accuracy, material structure, or affect their mechanical properties due to heating. The enclosed components (such as pin shafts, elastic support shafts) can be frozen. Cold assembly objects: assembly of various hot work molds and cold work molds, assembly of gears and shafts of various gearboxes, assembly of precision mechanical parts, assembly of various motor stators and rotors, assembly of automotive machinery and engine components
1.2.3 Cold assembly is equivalent to performing a cold treatment on the parts, and after cold treatment, the parts can obtain the following advantages:
1. The reduction of austenite can make the product remain unchanged for a long time;
2. Increase and averaging of hardness;
3. Improve the performance of machinery;
4. Dimensional stabilization;
5. Increase magnetism;
6. Enhanced wear resistance.
7. Improved efficiency and reduced worker labor intensity.
8. Fast cooling speed, able to quickly reach the process temperature.
9. No environmental pollution, the refrigeration medium is nitrogen.
10. Wide working temperature range, frost free.
11. The control system is advanced and programmable to operate.
12. Easy to operate and easy to maintain.
