Explosion Proof Test Chamber

Explosion proof test chamber is a equipment that can control temperature and humidity,it is an enhanced version of the constant temperature and humidity test chamber. Usually consisting of a control system, heating system, refrigeration system, humidification system, dehumidification system, etc. Through the collaboration of these systems, the test chamber can operate stably within the set temperature and humidity range.
The test chamber adopts advanced temperature and humidity control technology, which can accurately adjust the temperature and humidity values, making the test process more reliable and accurate. For some products that require high temperature and humidity, such as electronic components, medical equipment, etc., a constant temperature and humidity test chamber is an indispensable equipment.

Material testing: The explosion-proof test chamber can simulate various real temperature and humidity conditions to test the performance, durability, and adaptability of materials. For example, the deformation of various materials in high temperature and high humidity environments can be tested by adjusting the temperature and humidity of the test chamber.

Electronic product testing: For some electronic products that require high temperature and humidity, such as commonly used mobile phones, computers, etc. in daily life, explosion-proof test chambers can be used to test their performance and reliability under different environmental conditions. For example, a mobile phone can be placed in a test chamber and the temperature and humidity can be adjusted to the set values to observe whether the phone's response and performance are normal.

Automotive component testing: During the automotive manufacturing process, explosion-proof test chambers can be used to test the performance and durability of automotive components. For example, a certain component can be placed in a test chamber and its changes in different environments can be observed through cycling under different temperature and humidity conditions to evaluate its reliability and durability.

The cold temperature test chamber is machined by CNC machine tools, with beautiful appearance and non-reaction handles for easy operation. The inner shell of the chamber is made of imported high-grade stainless steel (SUS304) mirror panel, and the outer shell is made of A3 steel plate sprayed with plastic, which increases the appearance texture and cleanliness.
The large observation window with lighting keeps the chamber bright, and the embedded tempered glass in the heating element allows clear observation of the chamber conditions at any time. It is equipped with a test hole with a diameter of 50mm, which can be used for external test power cord or signal line.

The refrigeration system of the explosion proof test chamber operates based on the principle of compression refrigeration, with the compressor, condenser, throttle valve, and evaporator forming its core components.
In the compression stage, the refrigerant is adiabatically compressed by the compressor, and then transformed into a high-pressure and high-temperature state. This process consumes power, resulting in an increase in exhaust temperature.
Entering the condensation stage, the refrigerant under high pressure and high temperature will pass through the condenser and undergo isothermal heat exchange with the surrounding medium, transferring its own heat to the surrounding medium. During this process, the refrigerant gradually cools down and transforms into high-pressure liquid.
Next is the throttling process, where high-pressure liquid refrigerant undergoes adiabatic expansion through the throttling valve, resulting in a decrease in pressure and temperature, and becomes low-temperature and low-pressure wet vapor.
Finally, in the evaporation stage, the wet steam enters the evaporator and absorbs heat isothermally from the air or test sample, thereby reducing their temperature. The evaporated gas will be sucked into the compressor again, thus completing a complete cycle.

1, Equipment preparation work
Appearance inspection: The primary task is to carefully examine the appearance of the explosion proof test chamber and confirm that the chamber body is not damaged or deformed.
Internal cleaning inspection: Open the device and inspect the internal space to ensure that it is clean and tidy, without any debris or dust residue.
Power cord inspection: Carefully inspect the power cord and plug to confirm that their appearance is intact, without cracks or deformations, ensuring safe power on.
Reasonable placement of equipment: Choose a stable placement location, place the equipment properly, and ensure that there are no obstacles around the equipment to ensure good heat dissipation.
2, Startup operation process
Connect power supply: Insert the power cord correctly into the socket, then turn on the power switch of the device. At this time, the device should enter standby mode.
Power on self-test: Press the power button, and the device immediately starts the self-test program, automatically checking various parameters to confirm if they are normal.
Ready to run: After the self-test process is successfully completed, the device returns to standby mode and waits for the start of the test.
3, Parameter setting steps
Setting temperature and humidity: Based on the specific requirements of the experiment, the required temperature and humidity values can be accurately set through the temperature and humidity adjustment buttons equipped on the equipment or the touch screen.
Start test: After completing the parameter settings, press the start button and the equipment will immediately start running, automatically adjusting the temperature and humidity to create a test environment that meets the requirements.
4, Key points of operation monitoring
Real time viewing: During the experiment, the device's display screen or accompanying monitoring software can be used to view the current temperature and humidity values, as well as the overall operating status of the equipment in real time.
Fault handling: Once a device malfunction or abnormal operating status is detected, the test must be stopped immediately and professional maintenance personnel must be contacted in a timely manner to handle it.
5, End of experiment operation
Stop running: After the experiment is completed, press the stop button to stop the equipment from running.
Turn off power: Turn off the power switch of the device, unplug the power cord, and then clean the inside and outside of the device to remove debris and dust.
