Some advice from LandGlass about what items should be included in the monthly and yearly inspection of glass tempering machines.
Monthly inspections should include
- The tempering furnace must be cooled down once every month for ceramic rollers and tempering section cleaning.
- Check whether the furnace heating elements show grounding fault and the heating elements work properly
- The chains and bearings of the furnace must have effective lubrication.
- Clean dust from the electrical cabinet and inverter cooling ducts.
- Check the quenching blower coupling for concentricity.
- Check the blower blades for deformation and cracks.
- Replace the circulating cooling water to ensure that the water quality meets the standards.
- Check if the heating wire terminals and terminals in the heating electrical cabinet have become loose.
Yearly inspections should include
- Oil in all reducers of the tempering furnace must be changed.
- All drive bearings of the furnace must be purged and re-oiled.
- The motor bearing of the quenching blower must be purged and re-oiled.
- The convection blower must be replenished with oil as required.
- Check whether the power supply system and grounding resistance value of the furnace meet the requirements.
- Check the level of the roller conveyor of the tempering furnace with a flatness gauge.
- Clean the inside of the air duct system and chiller with a high-pressure water gun.
