Small maintenance knowledge of high and low temperature test chamber

1. High and low temperature test chambers are generally high. We recommend placing them in a relatively benign temperature environment. Our empirical temperature values ​​are 8 ° C ~ 23 ° C. For laboratories not equipped with such conditions, appropriate air conditioners must be provided. Or cooling tower.

2. Adhere to professional management of qualified personnel. Units with conditions should send special personnel to the supplier factory for training and training from time to time 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 dedusted to ensure its good ventilation and heat transfer performance; In addition to ensuring the inlet pressure and inlet temperature, the corresponding flow must be ensured. The interior of the condenser is periodically cleaned and descaled to obtain its continuous heat transfer performance.

4. Periodically clean the evaporator: Due to the different cleanliness level of the sample, a small amount of dust and other small particles will be condensed on the evaporator under the forced air circulation, and should be cleaned regularly.

5. Circulating fan and condenser fan cleaning and balance: similar to cleaning evaporator, due to the different working environment of the test box, small particles such as dust will be condensed on the circulating fan and condenser fan, and should be cleaned regularly.

6. Waterway and humidifier cleaning: If the waterway is not smooth, the humidifier scale is likely to cause the humidifier to dry, which may damage the humidifier, so 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 wall of the working chamber.

8. If the equipment needs to be relocated, it should be carried out under the guidance of the technical staff of Hongzhan Company to avoid unnecessary damage or damage to the equipment.

9. When the machine is not used for a long time, it should be energized every half month regularly. The power-on time is not less than 1 hour.

10. Maintenance principle:
Since the high and low temperature test chambers are basically composed of multiple systems of electricity, refrigeration and machinery, once the equipment has problems, the entire equipment system should be thoroughly inspected and comprehensively analyzed. Generally, the process of analysis and judgment can be "outside" and then "" "In the first step, after excluding external factors, the equipment is first systematically decomposed according to the fault phenomenon. After the analysis and judgment of the system comprehensively, or the reverse method can be used to find the cause of the fault: firstly, according to the electrical wiring diagram, whether the electrical system has The problem, after the Zui look for the problem of the refrigeration system. Before you can find out the cause of the failure, you must not disassemble or replace the parts, so as not to cause unnecessary trouble.
