Ceiling Channel Roll Forming Machine/Ceiling Batten Machine.
In modern society, there are two types
ceiling are quite popular: CU wall angel roll forming machines and the other is
T gird Roll Forming Machine. According to different customers, there are
different type`s requirements. But all those types, We have common size and customized size. All the machine is designed by customer's demand.

When the rapid temperature change test box suddenly fails during the test operation, a corresponding fault indication prompt appears on the control instrument. The operator can quickly check which type of fault belongs to in the troubleshooting chapter of the operation of the equipment, and then the professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment will have other phenomena in use, it must be specific phenomena, specific analysis and exclusion.
Rapid temperature change test chamber in high temperature test:
Fault 1: The temperature change cannot reach the test temperature value. Check the electrical system and eliminate the fault one by one.
Fault 2: When the temperature rises very slowly, it is necessary to check the wind circulation system to see if the wind turbine's regulating baffle is normally open. Conversely, check whether the wind turbine's operation is normal.
Fault 3: The temperature overshoots badly. Then you need to set the PID setting parameters.
Fault 4: The temperature rises directly and over-temperature protection. Then, if the controller fails, the control instrument must be replaced.
Fast temperature test chamber in low temperature test:
Failure: Low temperature does not reach the test target,
Remedy: Observe the temperature change, it is the temperature drop is very slow, or the temperature rises after the temperature reaches a certain value, the former must check, do the laboratory drying before the low temperature test, so that the studio is dry Then put the test sample into the working room and do the test again. The test sample in the work room is placed too much, so that the air in the work chamber cannot be fully circulated. After eliminating the above reasons, it is necessary to consider whether it is a fault in the refrigeration system. This will require the factory's professionals to overhaul. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location of the equipment (the distance between the cabinet and the wall) must meet the requirements (both are specified in the equipment operating instructions).
Rapid temperature change test chamber (fast temperature change) is suitable for aerospace products, information electronic instrumentation, materials, electricians, electronic products, a variety of electronic vitality instrumentation, chemical and other parts or the whole machine at high temperature or low temperature The adaptability test or the stress screening test under the condition of rapid change of humidity and heat or gradual change can help to make a scientific analysis and evaluation of the performance and change of the test sample under the conditions.
