Three-slot cold and hot impact tester
There are three test spaces, which are divided into heat storage area, cold storage area and test area, also known as static cold and hot impact test chamber. The sample is placed in the test chamber for high and low temperature cyclic impact test to simulate the physical changes caused by the rapid change of temperature of the product.
1. The product has beautiful appearance, reasonable structure, advanced technology and exquisite material selection. The air-cooled cold and hot impact test box has simple and convenient operation performance and reliable equipment performance.
2. The equipment is divided into three parts: high temperature box, low temperature box, and test box. It adopts a unique heat cutoff structure and thermal storage and cold storage effect. During the test, the object to be tested is completely static, and the cold and hot temperatures are introduced into the test area by using the cold and hot air circuit switching mode to achieve the purpose of cold and hot impact test
3. The most advanced measuring device is adopted, and the controller is a large color LCD human-machine touch dialog LCD human-machine interface controller, which is simple to operate, easy to learn, stable and reliable, and displays complete system operation status, execution and setting program curve in Chinese and English.
4. 96 test specifications are set independently, the impact time is 999 hours and 59 minutes, and the cycle period is 1~999 times, which can be set. The automatic operation of the refrigerator can be realized, the automation can be realized to the maximum extent, the workload of the operator can be reduced, and the operation can be automatically started and stopped at any time;
5. There is a test hole with a diameter of 50mm on the left side of the box, which can be used for external power load wiring test components.
6. The function of high temperature, low temperature and cold and hot shock can be independently set, and when performing cold and hot shock conditions, the function of two-slot or three-slot and cold and hot shock can be selected, which has the function of high and low temperature testing machine
7. It can be used independently as a high temperature box or a low temperature box, with one machine for three purposes.
8. It has a fully automatic and high-precision system circuit, any machine action, complete P.L.C locking processing, all of which adopt P.I.D automatic calculation control, and high temperature control accuracy.
9. Advanced and scientific air circulation design ensures uniform indoor temperature and avoids any dead angle; The complete safety protection device avoids any potential safety hazard and ensures the long-term reliability of the equipment.
10. The number of cycles and defrosting times can be set for automatic (manual) defrosting.
11. The air outlet is detected and controlled by the air return sensor. The switching time of the damper mechanism is 10 seconds, and the recovery time of the cold and hot shock temperature is 5 minutes.
12. Status display and curve display during operation. In case of abnormal conditions, the screen will automatically display the fault point and cause and provide troubleshooting methods. In case of unstable input power, emergency shutdown device will be provided.
13. The refrigeration system is designed with a cascade high efficiency and low temperature loop system. The refrigeration unit uses the original imported compressor from Europe and America, and uses the green environmental protection (HFC) refrigerants R507 and R23 with zero ozone coefficient.
14. Super-strong safety protection function: power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over-temperature protection, alarm sound prompt, etc.
