High and low temperature damp heat test box maintenance six key
High-low temperature hot and humid test chamber is suitable for aerospace products, information electronic instruments and meters, materials, electricians, electronic products, and various electronic vitality components in the high and low temperature or hot and humid environment, test its performance index. In the production and research and development process, the constant temperature and humidity testing machine plays a decisive role. Then, how to maintain the high and low temperature humidity test chamber ?
Daily cleaning maintenance is mainly divided into six areas:
First, the external cleaning and maintenance of the box:
1. The internal impurities should be removed before operation.
2. The power distribution room should be cleaned at least once a year or more. When cleaning, vacuum cleaners can be used to suck indoor dust.
3. The exterior of the cabinet must also be cleaned more than once a year. Wipe with soap and water before cleaning.
Second, humidifier inspection and maintenance:
The water storage in the humidifier should be replaced once a month to ensure that the water quality is clean. The humidifying water tray should be cleaned once a month to ensure smooth water flow.
Third, check the over-temperature protector:
During operation, the maximum setting of the over-temperature protection is 20°C~30°C. When the temperature in the test chamber rises to the set point of over-temperature protection, the power supply to the heater is stopped. The over-temperature warning light is on but the fan is still running. If it is running for a long time and unattended, be sure to check the over-temperature protection before operation. Whether it is set properly.
Fourth, the condenser dust removal:
The condenser should be maintained on a regular monthly basis, using a vacuum cleaner to suck the dust attached to the condenser heat-dissipating mesh or use high-pressure air to spray dust off.
Fifth, the replacement of wet ball gauze in the high-low temperature damp heat test box:
When the surface of the gauze is not clean or hardened, or after the temperature test is done, the gauze must be replaced before continuing the temperature and humidity test. Gauze is replaced about three months
VI. Check and adjustment of wet bulb water level:
The water level should not be too high, so that the water overflows the water cylinder or is too low to allow the wet ball test cloth to absorb water abnormally, affecting the accuracy of the wet bulb. The water level can be maintained at approximately six full minutes. Adjust the water level of the stagnant water tank to adjust the height of the water tank.
Allows users to feel more comfortable and comfortable, and prolongs the service life of high-low temperature hot and humid test chambers .
