High temperature ovens are widely used in biochemistry, chemical pharmacy, medical and health, agricultural scientific research, environmental protection and other research applications, for powder drying, baking and disinfection and sterilization of various glass containers. So how to clean and maintain the high temperature oven during the use of it? Here are a few key points to keep in mind:
  
  1. Cleaning and maintenance inside and outside the high temperature oven box
  
  1) The high temperature oven should remove the internal impurities before operation.
  
  2) The power distribution room should be cleaned less than once a year, and a vacuum cleaner can be used to remove the indoor dust when cleaning.
  
  3) The exterior of the box should also be cleaned more than once a year, just wipe it with soapy water.
  
  2. Inspection and maintenance of high temperature oven humidifier The water storage in the humidifier should be replaced once a month to ensure the water quality is clean, and the humidification water tray should be cleaned once a month to ensure smooth water flow.
  
  3. High-temperature oven inspection When the high-temperature aging test box of the over-temperature maintenance device is working, the set high value of the over-temperature maintenance should be increased by 20℃~30℃. When the temperature in the test box rises to the set point of over-temperature maintenance, the power supply of the heater will be terminated, and the "OVERHEAT" over-temperature warning light will be on, but the fan will still work. Is the temperature protector set properly [the setting of the wet bulb over-temperature protector is 120℃].
  
  4. High-temperature oven condenser dust removal The condenser should be maintained on a regular basis every month. Use a vacuum cleaner to absorb the dust attached to the condenser heat dissipation mesh or use high-pressure air to spray the dust.
  
  5. Replacement of Wet Bulb Test Cloth in High Temperature Oven When the surface of the test cloth is not clean or hardened, or after the temperature control is completed, the test cloth must be replaced before continuing the temperature and humidity control. The test cloth should be replaced about once every three months. When replacing, use a cleaning cloth to wipe the temperature measuring body [Sen-sor]. When replacing a new test cloth, it should be cleaned first.
  
6. Check and adjust the water level of the wet bulb in the high temperature oven. 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 bulb test cloth absorbs water abnormally, which affects the accuracy of the wet bulb. The water level should be about six points full. Can. The adjustment of the water level of the water tank can adjust the unevenness of the water tank.
