Talk about what the test box needs to pay attention to during normal times.

The constant temperature and humidity test chamber is also called constant temperature and humidity test machine, constant temperature and humidity test chamber or constant temperature machine or constant temperature and humidity chamber. It is used for testing equipment and various functions in various environments, and various kinds of materials are heat-resistant, cold-resistant and dry-resistant. Moisture resistance. Suitable for the quality of electronic, electrical, communication, appearance, vehicles, plastic products, metals, food, chemicals, building materials and medical products. The constant temperature and humidity test chamber is a test box for arranging high temperature and low temperature as well as damp heat. The repairing difficulty is more difficult and more representative than other environmental experimental equipment. Let's talk about the maintenance precautions and methods of the constant temperature and humidity test chamber.
1. The heat dissipation (condenser) of the refrigeration unit should be maintained regularly and kept clean. The dust paste condenser will cause the compressor high voltage switch to trip and the false alarm will occur. The condenser should be maintained monthly. Use the vacuum cleaner to remove the dust attached to the condenser hot mesh or use the hard brush after booting. Brush or use a high pressure nozzle to blow clean dust.
2. When taking the test object in the door or the furnace, do not touch the rubber edge of the item door to prevent the rubber edge from being damaged and shortening the life.
3. Keep the floor around the fuselage and the bottom of the fuselage at all times to avoid accidents and drops in the dust suction unit.
4. The freezing system is the center of the machine. Please check all copper pipes for leaks in a year. The horn joints and welding joints. If there is oil leakage, please tell the company or directly dispose of it.
5. The large current contact of the switchboard is cleaned and repaired at least once a year. The looseness of the contact will make the whole equipment in a dangerous working condition. If the component is burnt out, the attack will be serious, or the alarm or personal injury is very risky. Please clean it. Use a vacuum cleaner to remove indoor dust.
6. Humidifier and water rust are often clean, avoiding scale and affecting the emission of steam. Usually, once an experiment is done, the scale is cleaned in time to facilitate the life of the humidifying tube. When the water flow is smoothly cleaned, use a copper brush to flush it. Clean.
7. Wet cloth of dry and wet balls is often viewed. When the surface of the test cloth is unclean or hardened, or after being controlled at a temperature higher than 85 °C, continue to do before temperature and humidity control. If you are not able to absorb water, please replace it with the accuracy of moisture measurement. The test cloth is usually replaced once every three months. When replacing, use the cleaning cloth to scrub the temperature measuring body. When replacing the new test cloth, wash the hand first and then clean the water tank. Clean.
8. The wet water level is viewed in the adjustment: the water level of the water tank is not too high. Because the water overflows the water tank or is too low, the water absorption of the wet ball test cloth does not affect the accuracy of the wet ball. If the water level is about six minutes, you can adjust the water level of the water tank to adjust the water level of the water tank (adjust the screws on both sides)
9. The setting value of the over-temperature maintenance device in the distribution box should not be arbitrarily adjusted. It has been adjusted at the factory. This maintenance switch is used to maintain the heating pipe and humidification pipe empty and water shortage alarm, set point.
10. When the temperature in the test chamber rises to the set point of the over-temperature maintenance device, the power supply of the heater is suspended. The over-temperature warning light is on but the fan is still working. If it is working for a long time and unattended, please do not confirm before work. Check the over-temperature maintenance device, is it set to be stable.
11. The inspection and maintenance of the water tank of the test tank is a device that is easy to block and leak. Please check the appearance of water leakage and water shut-off regularly. If so, please promptly sweep or tell the company to store water in the humidifier. It should be replaced once a month to ensure clean water and smooth water flow.
12. When the test box is taken after the arrival of the test product, it is necessary to take the boring, anti-electricity and moisture-resistant gloves for the pick-and-place under the shutdown condition.
13. The cleaning and maintenance of the inside and outside of the test chamber should be removed from the internal impurities before operation. Use a vacuum cleaner to clean the room dust when cleaning at least once in the room. It is necessary to clean the outside of the test chamber once a year or more, and scrub with soapy water when cleaning.
