The necessity of regularly cleaning the evaporator of the high and low temperature impact test chamber
When we talk about cleaning the evaporator of the high and low temperature impact test box, it is actually a maintenance issue for the impact box. This type of test box is also known as an environmental testing machine, which tests the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. It is suitable for use in factories such as electronics, food, vehicles, chemicals, building materials, etc. However, after use, we must remember to maintain and maintain it. When maintaining, it is necessary for everyone to master the following precautions.
a. The high and low temperature impact test chamber should be fixed and the condenser should be cleaned every 3 months. For refrigeration systems that use air-cooled cooling, the condenser fan should be regularly inspected and the condenser should be cleaned and dusted to ensure good ventilation and heat transfer performance; For refrigeration systems that use water-cooled cooling, in addition to ensuring that the inlet water pressure and temperature are within the specified range, it is also necessary to ensure the corresponding flow rate and regularly clean and scale the inside of the condenser to obtain its continuous heat transfer performance.
If it is done at low temperature for a long time, after completing one cycle, the temperature should be set to 110 degrees and the door should be defrosted for two hours with a small amplitude. At the same time, it should be maintained that after each experiment, the temperature is set near the ambient temperature, and work for about 30 minutes before cutting off the power and wiping the inner wall of the workshop clean.
c. The evaporator of the high and low temperature impact test chamber should be cleaned regularly: due to the different cleanliness levels of the test samples, many small particles such as dust will accumulate on the evaporator under the action of forced air circulation, and should be cleaned regularly.
Cleaning and balancing of circulating air blades and condenser fans in high and low temperature impact test chambers: Similar to cleaning evaporators, due to the different working environments of the test chamber, many small particles such as dust may accumulate on the circulating air blades and condenser fans, and should be cleaned regularly.
d. Waterway and humidifier cleaning: If the waterway is not smooth and the humidifier scales, it is easy for the humidifier to dry and burn, which may damage the humidifier. Therefore, it is necessary to regularly clean the waterway and humidifier.
e. If the equipment needs to be relocated, it is best to do so under the guidance of technical personnel from Huakai Company to avoid equipment damage. If the customer relocates on their own, they must have a professional electrician to confirm that the circuit is correct before starting the machine, otherwise it will burn out the relevant components of the equipment.
f. If the equipment is not in use for a long time, it should be powered on regularly every half month for no less than 1 hour, and the relevant components of the equipment should be checked for normal operation.
So, in addition to the high and low temperature impact test chambers that require maintenance as mentioned above, products such as constant temperature and humidity test chambers, high and low temperature test chambers, etc., we should remember to maintain them after use. Therefore, through the above article, you have learned the importance of regular maintenance of impact chambers and cleaning of evaporators. Only by maintaining them in the correct way can we effectively extend their lifespan.
