Clean maintenance, protection and dust removal methods for constant temperature and humidity test chamber
1. Cleanliness and protection inside and outside the cabinet
1) Remove external impurities before holding.
2) The inside of the cabinet must also be cleaned more than once a year. Wipe with soapy water first.
3) The power distribution room should be cleaned at least once a year. When clean, you can use a vacuum cleaner to remove the indoor dust.
2. The water storage of the equipment should be changed once a month to ensure that the water quality is clean, and the humidifying water tray should be cleaned once a month to ensure the smooth flow of water.
3. When the constant temperature and humidity test chamber is in operation, the maximum value of the over-temperature maintenance is increased by 20 ℃ ~ 30 ℃. When the temperature in the test rises to the set point of over-temperature maintenance, the power supply of the heater is stopped, the over-temperature warning light is on but the fan is still running. Can it be set robustly [The setting of the wet bulb over-temperature maintenance device is 120 ° C.
4. The decondensation of the condenser dust in the constant temperature and humidity test chamber should be protected monthly, using a vacuum cleaner to absorb the dust attached to the cooling mesh of the condenser or spray the dust with a high-pressure atmosphere.
5. Change of the wet-ball test cloth When the test cloth is not clean or hardened, or after the temperature control is completed, the test cloth must be changed before continuing the temperature and humidity control. The test cloth should be changed every three months. When changing, wipe the temperature measurement body with a clean cloth. When changing the test cloth, it should be cleaned first.
6. The search and mediation of the water level of the wet bulb in the constant temperature and humidity test chamber must not be too high, so that the water overflows or is too low to make the wet bulb test cloth absorb water abnormally, affecting the accuracy of the wet bulb. Just fill up. The water level of the water tube can be adjusted to stop up and down the water box.
