1. The high and low temperature test chambers are generally relatively high. We recommend that they be placed in a relatively benign temperature environment. Our empirical temperature value is 8 ℃ ~ 23 ℃. For laboratories that do not have this condition, they must be equipped with appropriate air conditioners. Or cooling tower.
2. Adhere to the professional management of special personnel, units with conditions should send special personnel to the supplier's factory for training and learning from time to time to obtain more professional maintenance and repair experience and ability.
3.Fixedly clean the condenser every 3 months: For air-cooled compressors, the condenser fans should be regularly inspected and the condensers should be decontaminated and dusted to ensure good ventilation and heat transfer performance; for compressors, water-cooled cooling is used. In addition to ensuring the inlet pressure and temperature, the corresponding flow rate must be ensured, and the interior of the condenser must be cleaned and descaled regularly to obtain its continuous heat exchange performance.
4. Regularly clean the evaporator: due to the different cleanliness of the test products, under the action of forced air circulation, many small particles such as dust will condense on the evaporator, and it should be cleaned regularly.
5.Cleaning and balancing of circulating air blades and condenser fans: Similar to cleaning the evaporator, because the working environment of the test box is different, many small particles such as dust and other particles will condense on the circulating air blades and condenser fans, which should be cleaned regularly.
Then set the temperature near the ambient temperature, cut off the power after working for about 30 minutes, and wipe the inner wall of the work chamber clean.
7.If the equipment needs to be relocated, it is best to carry out under the guidance of the technical staff of Boss to avoid unnecessary damage or damage to the equipment.
8.When the machine is not used for a long time, the product should be regularly powered on every half a month for a period of not less than 1 hour.
Since the high and low temperature test box is basically composed of multiple systems of electrical, refrigeration and machinery, if there is a problem with the equipment, a comprehensive inspection and comprehensive analysis of the entire equipment system should be performed. First, check whether the electrical system is defective according to the electrical wiring diagram, and finally find Whether the cooling system is a problem. Do not disassemble or replace parts before you understand the cause of the failure to avoid unnecessary trouble.
