Maintenance of constant temperature and humidity test chamber
December 3, 2021
The constant temperature and humidity test box can simulate the experimental conditions of different environments such as high temperature, high temperature and low temperature, low temperature and low humidity. It is used to test the heat resistance, dry resistance, humidity resistance and cold resistance of materials to determine the product's aging resistance and special environment resistance. . It has been widely used in the electronics industry, national defense technology, chemical chemistry, machinery manufacturing and other fields.
The main point of maintaining the constant temperature and humidity test chamber is to pay attention to maintenance and cleaning, so how is the constant temperature and humidity chamber maintained, cleaned and maintained in the daily work?
First of all, the internal impurities should be cleaned before the operation of the constant temperature and humidity test chamber. The power distribution room should be cleaned at least once a year. When cleaning, a vacuum cleaner can be used to remove indoor dust. The outside of the body is also cleaned* more than once at a time. Wipe it with soap and water before cleaning.
The second is the inspection and maintenance of the humidifier. 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. Also, pay attention to the replacement of the test cloth in the constant temperature and humidity test box. 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, and the temperature measuring body should be wiped with a clean cloth when changing, and the test cloth should be cleaned first when the test cloth is renewed.
Afterwards, the point to be emphasized is the inspection and adjustment of the water level of the floating ball in the constant temperature and humidity box. The water level of the water tank should not be too high, so that the water overflows the water tank or is too low, so that the wet ball test cloth absorbs water abnormally, which affects the accuracy of the wet ball. Just keep six points full. The water level of the water tank can be adjusted to adjust the height of the water tank.
The dust of the condenser of the constant temperature and humidity test chamber is clear: the condenser should be regularly maintained monthly. Use a vacuum cleaner to absorb the dust attached to the condenser radiating mesh or use high-pressure air to spray out the dust.
