A device is just like a person. We have been in the hospital for decades and have been hospitalized more or less in this process. Therefore, people want to be healthy and long-lived, so people now pay more attention to health. Usually more maintenance, then the number of hospitals is certainly less than others. The same is true for high and low temperature test chambers , which require manual maintenance after normal use or long periods of non-use. Here are some tips for you , I hope to help you. 1. High and low temperature test chambers Generally, we recommend to place them at an ambient temperature of 8 ° C ~ 28 ° C. For laboratories that do not have this condition, appropriate air conditioning or heat sinks must be provided . 2. Adhere to professional management and maintenance of qualified personnel. Units with conditions should send special personnel to the supplier factory for training and training to obtain more professional maintenance and repair experience and ability. 3. Fix the condenser once every 3 months. For air-cooled cooling of the compressor, the condenser fan should be regularly repaired and the condenser should be decontaminated and dusted to ensure its good ventilation and heat transfer performance. For the compressor to use water-cooled cooling, in addition to ensuring its inlet pressure and inlet temperature, the corresponding flow must be ensured, and the inside of the condenser should be cleaned and descaled regularly to obtain its continuous heat transfer performance. 4, regular cleaning of the evaporator: due to the different levels of cleanliness of the sample, under the forced air circulation, the evaporator will condense a lot of small particles such as dust, should be cleaned regularly. 5, circulating fan, condenser fan cleaning and balance similar to the cleaning evaporator, because the working environment of the test box is different, the circulating fan and condenser fan will condense a lot of small particles such as dust, should be cleaned regularly. 6. Waterway and humidifier cleaning: If the waterway is not smooth and the humidifier is fouled, it may cause the humidifier to dry and may damage the humidifier. Therefore, the waterway and humidifier must be cleaned regularly. 7. After the completion of each test, set the temperature near the ambient temperature, and then cut off the power after working for about 30 minutes, and wipe the inner wall of the working room. 8. When the machine is not used for a long time, it should be energized every half month periodically. The power-on time is not less than 1 hour. Since the high and low temperature test chambers are basically composed of multiple systems of electricity and refrigeration, once the equipment has problems, the entire equipment system should be thoroughly inspected and comprehensively analyzed. Generally speaking, the process of analysis and judgment can be first and foremost, that is, after excluding external factors, the equipment is systematically decomposed according to the fault phenomenon , and then the system comprehensive analysis and judgment, or the reverse method can be used to find the cause of the fault. First, according to the electrical wiring diagram, find out if there is a problem with the electrical system, and finally find out whether the refrigeration system is a problem. Do not disassemble or replace parts before you find out the cause of the malfunction, so as not to cause unnecessary trouble. Each device will use an operator, who is the master of the master device. The owner is responsible for the family, and he must care for the equipment he uses as much as he loves his family. Remind the majority of the use, spend a little more time every day to do high-low temperature test box inspection, testing, cleaning and other maintenance work, will greatly reduce the incidence of failure, improve your production efficiency
