How to effectively remove dust in a constant temperature and
2020-08-18
So how is the constant temperature and humidity test chamber maintained, cleaned and maintained in daily work?
1. Cleaning and maintenance of the inside and outside of the constant temperature and humidity test chamber
1) The constant temperature and humidity test chamber should be cleaned of internal impurities before operation.
2) The power distribution room is cleaned at least once a year, and the dust in the room can be removed by a vacuum cleaner when cleaning.
3) The exterior of the cabinet must also be cleaned more than once a year, first wipe it with soapy water.
2. Inspection and maintenance of humidifier in constant temperature and humidity test chamber
The water storage in the humidifier should be replaced once a month to ensure that the water is clean. The humidification pan should be cleaned once a month to ensure smooth water flow.
3. Check the over-temperature protector in the constant temperature and humidity test box
When the constant temperature and humidity test chamber is in operation, the maximum set value of over-temperature protection is increased by 20℃~30℃. When the temperature in the test chamber rises to the set point of over-temperature protection, the heater's power supply will stop, the "OVERHEAT" over-temperature warning light is on but the fan is still running. If it is running for a long time and left unattended, please make sure to check it before running. Whether the over-temperature protector is set properly [The setting of the wet-bulb over-temperature protector is 120℃.
4. Removal of dust from the condenser of the constant temperature and humidity test chamber
The condenser should be regularly maintained monthly. Use a vacuum cleaner to suck off the dust attached to the condenser's heat sink or use high-pressure air to spray dust.
5. Replacement of wet ball test cloth in constant temperature and humidity test chamber
When the surface of the test cloth is dirty or hard, or after the temperature control is completed, the test cloth must be replaced before continuing the temperature and humidity sphericity control. The test cloth should be replaced once every three months. When replacing, wipe the temperature sensor [Sen-sor] with a cleaning cloth, and clean it first when replacing the new test cloth.
6. Inspection and adjustment of the wet bulb water level in the constant temperature and humidity test chamber
The water level of the water tank should not be too high, so that the water overflows the water tank or is too low to make the wet ball test cloth absorb abnormally, and affect the accuracy of the wet ball. The water level can be about six minutes full. The water level of the water tank can be adjusted to adjust the height of the water tank.
