Screen is covered outside 5.
Screen dish 6.
Screw cap 7. Lid cap bolt 3. Structure and characteristic cathode belt support by lid cap bolt, screw cap, screen dish, outside screen is covered, inside screen is covered, insulation bearing with protection base is comprised. (Reed of outfit of 1) cathode bearing and cathode dish osculatory place does not hit arc cathode belt support and negative pole dish between it is to collect bolt of plain lid cap and cathode dish osculatory bearing. What use as a result of lid cap bolt is cathode of spherical part bearing dish, namely spherical the point contact with plane, share 3 each other to be nodded into the bearing of 120º , this kind of structure makes lid cap bolt and cathode dish the contact is very good, it is very easy to adjust, although height of 3 bearing dot is different,differ relatively a long time also does not hit arc. (2) cathode dish height is adjustable cathode dish height can be adjusted by screw cap, adjust the screw cap of 3 cathode belt support, can make cathode dish the high requirement of planar up to par. (3) has integrated screen clearance to protect the characteristic according to glow discharge, when cathode fall area Dk is less than a rated distance or be planted by some when the object jams, glow goes out by oneself namely. Because this is in fore-and-aft screen clearance, generation band mixes the screen of glow not to produce glow outside screen is covered between make one crack (like the graph 2 show) , want aperture M:a only=10:1, and the width of A is about 0.
9mm left and right sides, can become a kind " air gap is protected " structure. It is with manage in transverse screen clearance, n:b=10:1. Graph 2 in this cathode belt support, divide lid cap bolt and cathode dish when the contact, because be spherical the point contact with plane, so lid cap bolt and cathode dish between do not hit arc. Screw cap divides adjustable cathode dish outside height, still have 2 protection of screen clearance. Screen dish with outside screen is covered between form protection of fore-and-aft screen clearance, make screen dish the following part does not produce glow, and screen dish the diameter is more than outside the diameter that screen covers, electric object won't fall make between two body both guide. Screen is covered inside through insulation bearing with outside screen is covered form aperture screen, once screen dish the screen outside mixing is covered guide connect the screen outside making to cover glow, screen is covered outside and inside screen covers the gap between 6 form transverse screen clearance to act well instantly, undertake 2 times protective, protection of transverse screen clearance extinguishs glow. (4) screen clearance protects a consist in metal and metal between, protected metalloid insulation bearing open of the screen inside the surface is covered use a metal to be made, will metalloid insulating part overspreads amid, make its never hit arc and spare attaint. Screen dish with outside screen open is covered form fore-and-aft screen clearance protection, screen is covered outside with inside screen is covered form transverse screen clearance protection, they are metallic stuff component entirely, nonexistent the danger that plays arc to be destroyed. Insulation bearing have 3 groove, can prevent to splash shoot content covers its face and make be isolated from bearing become one conductor. Protective base has protective insulation bearing action, have again at the same time with insulation bearing the insulation action that protects aperture C because of existing, such making cathode belt support and furnace base insulation (although the surface is splashed to shoot content to splash full) , consequently cathode dish maintain insulation from beginning to end with whole body of heater. 4. This cathode belt support already was in epilogue different ionic nitrogen is changed undertook applied in furnace, cathode belt support and cathode dish osculatory place never has hit arc, integrated screen clearance never also has had appeared to guide a phenomenon that destroys, insulation bearing by inside screen is covered cover the part never hits arc, dimension does not have any change. Insulation bearing 3 groove, prevent the surface effectively to be not splashed to shoot content to bestrew, the protective aperture C that protects base makes be isolated from from beginning to end bearing maintain insulation with furnace base, after can accomplishing installation, departmental cent need not undertake any clearing again with care and maintenance.
