Keep in mind! Constant temperature and humidity test chamber maintenance points

Constant temperature and humidity chamber is suitable for the simulation of various kinds of materials, electronic electrician semi-finished products, finished products, such as high and low temperature constant and the gradient, mutation, alternating, humid heat test environment simulation experiment using reliability test and combining with the charge and discharge cabinet can high batteries charging and discharging test at low temperature. Is air at the same time, car, home appliance, scientific research in areas such as the necessary test equipment, used to test and determine the electrician, electronics and other products and material temperature constant temperature and humidity, as well as the environment changes after parameters and performance. Because of the constant temperature and humidity test chamber value is higher, generally needs regular maintenance and maintenance, main points are as follows: the point 1, because of the constant temperature and humidity test chamber value is generally higher, we suggest to place it in compared commonly benign environment temperature, temperature range is 8 ℃ to 23 ℃, to do not have the condition of laboratory, must be equipped with the appropriate air conditioner ( Air cooling) Or cooling tower ( Water cooling) 。 The point 2, adhere to professional management personnel. Conditional unit, should be regularly assign personnel to the supplier factory training and study, to obtain the professional maintenance, maintenance experience and ability. The point 3, on a regular basis ( Every 3 months) Condenser cleaning: for compressor adopts air cooling, should be regular maintenance the cooling fan, and the condenser decontamination dust removal, to ensure the good ventilation and heat transfer performance; For compressor adopts water cooling, except shall ensure that the inlet pressure, inlet temperature, also must ensure that the appropriate flow, and regularly to cleaning descaling of condenser inside, in order to get the continuous heat exchange performance. The point 4, on a regular basis ( Every 3 months) Clean the evaporation ( Dehumidification) : because of different sample sample clean level, under the effect of forced air circulation, the evaporation ( Dehumidification) Will condense a lot of dust particles, such as object, should be cleaned on a regular basis. Point 5, circular blades, condenser fan cleaning and calibration balance: similar to clean the evaporator, due to the different work environment test chamber, circular blades, condenser fan will condense a lot of dust particles, such as object, should be cleaned on a regular basis. Respect the customer friend, our environmental test chamber is high and low temperature test chamber, hot and cold impact test chamber, salt spray test chamber, aging boxes, uv aging box, xenon lamp aging box, get wet in the rain, sand dust box, etc. , more maintenance knowledge for environmental test chamber, please continue to focus on jester testing equipment company's website or contact us.
