3.1 The definition of terms in this standard adopts the interpretation of GB2900. 3.2 Multi-groove guide wheel Multigroove idler sheave A guide wheel with multiple wire grooves on the circumference of a wheel body. 3.3 Single-groove guide wheel Singlegroove idler sheave A guide wheel with only one wire groove on the circumference of a wheel body. 3.4 Gather up pooling
A method of collecting and arranging wires in which multiple enameled wires are concentratedly pulled by a traction wheel and then wound on the drum separately. The device is an independent component consisting of multi-head centralized traction, multi-head centralized wiring or single-head wiring, and single-head winding, called a centralized wire-taking device. The type of centralized wire-taking device can be a traction wheel or a group of traction wheels. 3.5 Single-head spooling Each enameled wire is pulled individually by a traction wheel and then wound on a reel. The device is a unit consisting of single-head traction, single-head wiring and single-head winding, called a single-head wire-taking device. The enameling equipment can be equipped with the number of single-head wire-taking devices according to the number of heads, or the specifications of the single-head wire-taking device can be adjusted according to the wire diameter and the reel capacity.
3.6 Off-gas cleaning
The treatment of eliminating harmful gases in the flue gas generated in the furnace during the baking process. Catalytic combustion is a way of flue gas purification, which ignites the flue gas through the action of a catalyst for purification. 3.7 Hot air circulation Hot air circulation is a process method that uses forced ventilation to return the purified hot air to the furnace to bake the insulating paint film. 4 Naming and code
