There are many aspects to the maintenance of glass tempering furnaces. Proper maintenance can reduce equipment failures, extend the service life, and improve the pass rate of tempered glass. Today, let's talk about the maintenance of glass tempering furnace units:

The glass tempering furnace assembly is mainly composed of four major sections: the fragment discharge section, the convection heating section, the flat tempering section, and the fragment collection section. It also includes a high-pressure centrifugal fan, air supply pipelines, air collection boxes, gas lines, electrical control cabinets, and operator stations.

1. Daily Inspection Content:

(1) Are all protective covers complete and clean?

(2) Check the responsiveness of the operation switch, photo eyes, limit switches, furnace door cylinder, and transmission encoder (connection).

(3) Air door actuator, air grille duct, fan shaft temperature, oil level, coupling, air grille proximity switch;

(4) Check for movement in the main drive ceramic roller shaft head, any non-rotating phenomena in the ceramic roller, and whether the hand-cranked air grate drive turns smoothly and flexibly.

(5) Check for any looseness, disengagement, poor lubrication, or issues with transmission chains (lubrication and tension). Address or notify the equipment department of any problems promptly.

2. Weekly Inspection Content

(1) Inspect the oil levels, temperature rise, and operational sounds of all motors for normalcy.

(2) Inspect the furnace top thermocouple and heating lines, verify that the heating, temperature display, and gauge readings are normal.

(3) Inspect pneumatic components, travel switches (safety features), air routes (sealing), and gas source effluent.

3. Monthly Inspection Content

(1) Inspect the furnace top lifting and the furnace top cone valve.

(2) Heating wire to ground, equipment grounded.

(3) Ensure proper oil level in the fan bearing housing and normal bearing temperature; immediately initiate an emergency power shutdown upon any abnormal conditions.

Aircraft components are complex and diverse, with critical or frequently failing parts requiring daily inspection, while others can be checked on a weekly or monthly basis.
