Solution
Dry filter units are generally referred to as "filter units". It is installed between the cooler and the capillary of the constant temperature and humidity Test Chamber. The key function is to digest and absorb the residual moisture, dust, metal materials and other dirt in the refrigeration unit, and prevent a small amount of residue and moisture in the refrigerant from entering the capillary, causing common faults such as "ice blockage" or "ice blockage". "Dirty and blocked", causing the refrigeration unit to fail to work normally. Then the question arises, what should we do if the dry filter device cannot work normally?
The technical engineer suggested that the dry filter device should be replaced when it fails, but if there is no new filter device for the time being, you can simply start the filter device to solve the problem.
Remove the dry filter device in the refrigerating unit of the constant temperature and humidity Test Chamber and soak it in a container full of gasoline for car cleaning. When the fluffing agent is dirty, tap the site of the filter device with a wooden stick to remove the dirt. Afterwards, take it out after continuous cleaning in motor gasoline, point to both sides of the filter device with dry N2 and continuously blow air, and then put it into clean motor gasoline for continuous cleaning.
After dismantling, this process requires technical professionals, specialized technicians, as special Electric Ovens and technical skills are required.
maintenance skills
1. Power supply voltage: The working voltage of the office environment of the constant temperature and humidity Test Chamber needs to be stable. If there is a short circuit, the current will be too large or too small. In this case, long-term operation will cause huge damage to the refrigeration compressor. It is recommended to use a regulated power supply to connect to the constant temperature and humidity Test Chamber.
2. Natural ventilation: Keep the office environment well-ventilated and dust-free, and clean up the refrigeration compressor in time. If the constant temperature and humidity Test Chamber is not used for a long time, it should be placed in a naturally ventilated and dust-free place.
3. No need to start frequently: when using a constant temperature and humidity Test Chamber, there is no need to start the refrigeration compressor frequently. The starting interval of the refrigeration compressor should be more than 15 minutes.
4. Natural environment application: smooth road surface, good natural ventilation, no flammables, corrosive smoke and dust, no strong electromagnetic radiation source around, and the working temperature is controlled at 5 ℃ ~ 30 ℃ (average temperature within 24 hours ≤ 30 ℃) ℃) , The ambient humidity is controlled at ≤85%RH.
Doing a good job in the maintenance of the refrigeration compressor is very important for the maintenance of the constant temperature and humidity Test Chamber. In addition, the application of constant temperature and humidity Test Chambers in natural environments is also very important.
