What should be paid attention to in the operation of glass tempering furnace
Glass tempering furnace mechanical equipment accessories for the importance of tempering furnace is equivalent to the right arm of people, is irreplaceable and lack. High quality steel furnace accessories can extend the service life of the furnace, so as to improve the efficiency of the furnace. If there is a problem in the operation of one of the accessories, it may cause the whole machine to stop production for maintenance. What's more, if the damage of accessories is not found in time, the whole machine will be damaged or even scrapped. Although the accessories are small, they play an important role in the operation of the whole equipment.

If the quality of accessories is not up to standard, there is a slight difference, which will affect the performance and quality of the whole equipment. Whether the fan of tempering furnace is used normally is related to whether the glass tempering furnace can work normally or not, and has a very important impact on the stability of the production line.
1. Preparation and inspection before operation: close the air inlet regulating valve of the fan of glass tempering furnace, slightly open the air outlet regulating valve, check the gap size of each part of the fan, whether there is collision and friction between the rotating part and the fixed part; check whether the electrical device is in good condition to prevent electric shock; check whether the safety protection device is reliable; check whether there is dust and dirt on the fan blade, and whether the blade is worn 。
2. Management in operation: when the fan of automobile glass tempering furnace starts up and reaches the normal speed, check whether the bearing temperature is normal during the operation. The temperature rise of the fan bearing of the tempering furnace shall not be greater than 40 ℃. If the temperature of the fan bearing rises rapidly, the emergency shutdown must be carried out. Check whether the connecting bolts of fan casing, bearing pedestal and bracket, bearing pedestal and bearing cover are loose; check whether the fan shaft of tempering furnace is concentric with the motor shaft, and whether there is friction between the casing and the impeller; check whether the foundation of the fan is firm, whether the impeller is loose or deformed, which makes the fan shake and impact violently; check whether the lubrication points of the fan bearing of the tempering furnace are lubricated Whether the oil and lubrication are normal. Check the fan motor for excessive current or high temperature.
