The reasons and Solutions for Abnormal high temperature cooling Fan of force convection Fan in Glass Tempering Furnace

1. Problem description

The abnormal performance of the convection fan cooling fan in the high-temperature furnace of the tempering furnace is manifested by increased sound, abnormal noise, and abnormal temperature, which may affect the normal operation of the furnace and industrial production.

2. Cause analysis

2.1. Oil stains: Oil stains on the inner and outer surfaces of the fan, or excessive oil stains on the pipeline inlet, can cause an increase in the fan's load.

2.2. Fan blade wear: After long-term use, the fan blades are severely worn, which can reduce the air volume and thus affect the performance of the fan.

2.3. Fan damage: Fan damage can cause uneven air flow, decreased air volume, and have adverse effects on the tempering furnace.

2.4. Insufficient cooling water supply: The convection fan cooling fan of the high-temperature furnace requires a large amount of water to cool. If the cooling water supply is insufficient, it will cause the fan temperature to be too high.

3. Solution

3.1. Cleaning the fan: Thoroughly clean the inner and outer surfaces of the fan with a cleaning agent to thoroughly remove oil and other dirt on the surface of the fan.

3.2. Replace fan blades: When the internal or external blades of the fan have been severely worn, new fan blades need to be replaced.

3.3. Replace the fan: If the fan is damaged and cannot be repaired, a new fan needs to be replaced.

3.4. Increase cooling water supply: The cooling fan of the convection fan in the high-temperature furnace of the tempering furnace requires a large amount of water. If the cooling water supply is insufficient, it is necessary to increase the cooling water supply to ensure the normal operation of the fan.

In short, the issue of abnormal convection fan cooling fan in the high-temperature furnace of the tempering furnace has attracted people's attention, which is very unfavorable for the normal use of the tempering furnace. This article introduces the causes and solutions of fan abnormalities. We should take corresponding measures according to the specific situation to avoid the occurrence of problems and ensure the normal use of the tempering furnace.
