thermal shock chamberPurpose:
Suitable for adaptability testing (impact) of equipment in the defense industry, aviation industry, automation components, automotive parts, electronic and electrical instrument components, electrical products, plastics, chemical industry, food industry, pharmaceutical industry, and related products under rapid temperature changes in the surrounding atmosphere. Suitable for adaptability testing and stress screening testing of instruments, meters, electrical and electronic products and components under rapid or gradual temperature changes, in order to analyze and evaluate the performance and behavior of test samples under specified conditions (rapid changes).
thermal shock chamberFeatures:
The product has a beautiful appearance, reasonable structure, advanced technology, and carefully selected materials. It has simple and convenient operation performance and reliable equipment performance.
The equipment is divided into three parts: a high-temperature box, a low-temperature box, and a testing box. It adopts a thermal insulation structure and a thermal storage and cooling effect. During the test, the test object is stationary, and the cold and hot air paths are switched to introduce the cold and hot temperatures into the testing area to achieve the purpose of cold and hot shock testingAdopting high-performance energy storage devices, the controller adopts a large color LCD human-machine touch dialogue LCD human-machine interface controller, which is easy to operate, easy to learn, stable and reliable, and displays complete system operation status, execution and program setting curves in both Chinese and English.
With 96 independent test specifications, the impact time is 999 hours and 59 minutes, and the cycle time can be set from 1 to 999 times. It can achieve automatic operation of the refrigeration machine, minimize the workload of operators, and can automatically start and stop working at any time;There is a test hole with a diameter of 50mm on the left side of the box, which can be used to test components for external power load wiring.
It can independently set the functions of high temperature, low temperature, and hot cold shock, and can choose two slot or three slot and cold shock and hot shock functions when performing hot and cold shock conditions. It has the function of a high and low temperature testing machine.
Equipped with fully automatic, high-precision system circuits, any component action, P.L.C locking processing, all using P.I.D automatic calculation control, high temperature control accuracyAdvanced scientific air circulation design ensures uniform indoor temperature and avoids any dead corners; Complete safety protection devices prevent any potential safety hazards and ensure the long-term reliability of the equipmentThe number of cycles and defrosting times can be set for automatic (manual) defrostingThe air outlet is detected and controlled by the return air outlet sensor. The switching time of the air door mechanism is completed within 10 seconds, and the recovery time of the cold and hot shock temperature is completed within 5 minutes.
During operation, the status display and curve display automatically show the fault point and cause on the screen in case of abnormal conditions, and provide troubleshooting methods. It also has an emergency stop device when unstable input power is detected.
The refrigeration system adopts a cascade low-temperature circuit system design, and the refrigeration unit adopts imported compressors from Europe and America, and uses green and environmentally friendly (HFC) refrigerants R507 and R23 with zero ozone coefficient*Safety protection functions: power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over temperature protection, alarm sound prompt, etc.
The internal and external materials of the box are made of stainless steel plates (SUS # 304), and there are different external box materials to choose from:
1. Texture treatment on stainless steel surface, if frequently wiped along the texture, can keep the machine in a brand new appearance for a long time (recommended choice)
2. Special anti rust treatment steel plate electrostatic spraying surface, texture (according to customer requirements), each product is customized according to customer requirements, ensuring the energy saving of the equipment, and on-site debugging and acceptance to ensure the user's performance.
