Many manufacturing enterprises now require production environments to maintain certain humidity or temperature levels. This is especially true in agricultural production and the manufacturing of many electronic components, where environmental control is crucial. Temperature and humidity are undoubtedly two extremely important indicators of the production environment. To effectively control humidity and temperature, constant temperature and humidity machines must be used. However, like any equipment, they cannot be used for extended periods without maintenance. The maintenance of constant temperature and humidity machines is therefore essential. Today, I will discuss the key points of maintaining these machines and how to carry out the maintenance. 1. **Cleaning and Maintenance of the Constant Temperature and Humidity Machine's Interior and Exterior:** Before operating the constant temperature and humidity test chamber, impurities inside should be removed. The electrical room should be cleaned at least once a year, and a vacuum cleaner can be used to remove dust. The exterior of the machine should also be cleaned at least once a year, simply by wiping it down. 2. **Inspection and Maintenance of the Humidifier:** The water in the humidifier should be changed once a month to ensure water quality is clean. The humidifying water tray should also be cleaned once a month to ensure smooth water flow. 3. **Checking the Overtemperature Protector:** When the constant temperature and humidity test chamber is in operation, the overtemperature protection is set to a maximum value of 20°C to 30°C above the set point. When the temperature inside the test chamber reaches the overtemperature protection set point, the power to the heater will stop, and the overtemperature warning light will illuminate, but the fan will continue to operate. If the machine runs for a long time unattended, it is essential to check the overtemperature protector to ensure it is set correctly before operation. 4. **Cleaning Dust from the Condenser:** The condenser should be maintained regularly, at least once a month, by using a vacuum cleaner to remove dust from the condenser's heat dissipation mesh or by using high-pressure air to blow off the dust. 5. **Replacing the Wet Bulb Test Cloth:** The test cloth should be replaced when its surface is dirty or hard, or after completing temperature control before continuing with wet bulb temperature control. The test cloth should be replaced approximately every three months. When replacing, use a clean cloth to wipe the temperature measuring body, and ensure the new test cloth is cleaned before installation. 6. **Checking and Adjusting the Water Level of the Wet Bulb:** The water level in the collection tank should not be too high to prevent overflow or too low to ensure the wet bulb test cloth absorbs water properly, which affects the accuracy of the wet bulb. The water level should be maintained at about six-tenths full. The water level can be adjusted by changing the height of the collection box.
Many manufacturing enterprises now require production environments to be maintained at certain humidity or temperature levels. This is especially true in agricultural production and the production of many electronic components, where environmental control is emphasized. Temperature and humidity are undoubtedly two extremely important indicators of the production environment. To effectively control humidity and temperature, a constant temperature and humidity machine must be used. However, no equipment can be used for extended periods of time, and constant temperature and humidity machines are no exception. Therefore, maintenance and care for constant temperature and humidity machines are essential. Today, I will discuss the key points of maintaining constant temperature and humidity machines.
1. Cleaning and maintenance of the internal and external parts of the constant temperature and humidity machine:
Before operating the constant temperature and humidity test chamber, impurities inside should be removed. The power distribution room should be cleaned at least once a year. A vacuum cleaner can be used to remove dust from the room. The external part of the chamber should also be cleaned at least once a year.
2. Inspection and maintenance of the humidifier in the constant temperature and humidity test chamber:
The water in the humidifier should be changed once a month to ensure water quality is clean. The humidifying water tray should be cleaned once a month to ensure smooth water flow.
3. Checking the over-temperature protector of the constant temperature and humidity test chamber:
When the constant temperature and humidity test chamber is operating, the over-temperature protection is set to a maximum value of 20℃~30℃ above the set point. When the temperature inside the test chamber reaches the over-temperature protection set point, the power supply to the heater will stop, the over-temperature warning light will turn on, but the fan will continue to operate. If it runs for a long time without supervision, please ensure to check the over-temperature protector before operation to confirm it is set correctly.
4. Cleaning the dust from the condenser of the constant temperature and humidity test chamber:
The condenser should be maintained regularly, at least once a month, using a vacuum cleaner to remove dust from the condenser's heat dissipation mesh or using high-pressure air to blow off the dust.
5. Replacement of the wet bulb testing cloth in the constant temperature and humidity test chamber:
When the surface of the testing cloth is dirty or hard, or after completing temperature control and before continuing with wet bulb temperature control, the testing cloth must be replaced. The testing cloth should be replaced approximately every three months. When replacing, use a clean cloth to wipe the temperature measuring body, and ensure the new testing cloth is cleaned before use.
6. Checking and adjusting the water level of the wet bulb in the constant temperature and humidity test chamber:
The water level in the collection tank should not be too high to prevent overflow or too low to ensure the wet bulb testing cloth absorbs water properly, which affects the accuracy of the wet bulb. The water level should be maintained at about six-tenths full. The water level in the collection tank can be adjusted by changing the height of the collection box.
