Qin Zhuo teaches you how to maintain high and low temperature test chamber, constant temperature and humidity test chamber

Dongguan Qinzhuo Environmental Testing Equipment Co., Ltd. has a good reputation in the industry. If you often use this machine for testing, daily maintenance is critical. Now let ’s take a look at how to maintain the high and low temperature test chamber:

When the machine is not used for a long period of time, the product should be regularly powered on every half month, and the power-on time should not be less than 1 hour

Regularly clean the condenser every 3 months: for compressors that are cooled by air, the condenser fan should be regularly repaired and the condenser should be decontaminated and dedusted to ensure its good ventilation and heat exchange performance; for compressors that are cooled by water, In addition to ensuring its inlet water pressure and inlet water temperature, it must also ensure the corresponding flow rate, and regularly clean and descale the inside of the condenser to obtain its continuous heat exchange performance.

Insist on setting the temperature near the ambient temperature after each test, cut off the power after working for about 30 minutes, and wipe the wall of the working room clean.

Cleaning and balancing of circulating fan blades and condenser fans: similar to cleaning evaporators, due to the different working environment of the test chamber, many small particles such as dust will condensate on the circulating fan blades and condenser fans, and should be cleaned regularly.

Waterway and humidifier cleaning: If the waterway is not smooth and the humidifier is fouled, it will easily cause the humidifier to dry and burn, which may damage the humidifier, so the waterway and humidifier must be cleaned regularly.

If the equipment needs to be relocated, it is best to be carried out under the guidance of Linpin's technical staff to avoid unnecessary damage or damage to the equipment.

High and low temperature test chambers are generally relatively high, we recommend placing them in a relatively benign temperature environment, our experience temperature value is 8 ℃ ~ 23 ℃, for laboratories that do not have this condition, must be equipped with appropriate air conditioners or cooling tower.

Maintenance principles:

Since the high and low temperature test chamber is basically composed of multiple systems of electrical, refrigeration and mechanical, once there is a problem with the equipment, the entire equipment system should be fully inspected and comprehensively analyzed. Generally speaking, the process of analysis and judgment can be "outside" and then " "Li", that is, after first eliminating external factors, the system is first decomposed according to the fault phenomenon. Then the system is comprehensively analyzed and judged. Or the backward reasoning method can be used to find the cause of the fault: first, find out whether the electrical system has Problems, and finally find out whether the refrigeration system is a problem. Before you understand the cause of the failure, you must not disassemble or replace parts to avoid unnecessary trouble.
