How to maintain high and low temperature test chamber

How to maintain the high and low temperature test box? How should the high and low temperature test box be maintained? The high and low temperature test box is mainly used in the high and low temperature environment of aerospace products and electronic products. It often maintains high and low temperature test boxes scientifically and reasonably, which not only can maximize the high The service life of cryogenic test chambers, and can effectively avoid technical failure due to maintenance.

First, the condenser cleaning to be in place Under normal circumstances, it is best to clean the condenser once every 3 months: For the compressor with air-cooled cooling, the condenser fan should be overhauled and the condenser decontaminated dust to ensure that it is good Ventilation heat transfer performance; For compressors using water-cooled cooling, in addition to ensuring the inlet pressure and inlet temperature, it must also ensure that the corresponding flow rate. And the condenser interior cleaning and descaling to obtain its continuous heat transfer performance .

Second, the ambient temperature to moderate high and low temperature test chamber temperature is generally higher, we recommend that it is placed in a relatively benign temperature environment, our experience temperature is 8 °C ~ 23 °C, for those who do not have this condition, must Equipped with an appropriate air conditioner or cooling tower.

Third, managers must professionally adhere to professional management, and qualified units should send personnel from time to time to the supplier factory for training. To obtain more professional maintenance and repair experience and ability.

Fourth, the waterway and humidifier cleaning To regular waterway and humidifier cleaning: If the water is not smooth, humidifier scaling easily lead to humidifier dry, may damage the humidifier, so you must regularly clean the waterway and humidifier.

V. Evaporator cleaning To regularly clean the evaporator regularly: Due to the different levels of cleanliness of the sample, a small amount of dust and other small particles will be condensed on the evaporator under the action of forced air circulation, and cleaning should be performed regularly.

VI. Cycling fan and condenser fan Cleaning It is necessary to periodically circulate fan blades and condenser fans to clean and balance: similar to cleaning evaporators, because the working environment of the test box is different, the circulation fan and condenser fan will condense a lot. Dust and other small particles should be cleaned regularly.

7. After the test, the work should be improved. Persist in setting the temperature around the ambient temperature after each test. After about 30 minutes of work, cut off the power supply and clean the inner wall of the work chamber.
