Soluzzjoni Għal Kuntatt Fqir Ta 'Wajer ta' Reżistenza ta 'Elementi ta' Sħana Tubulari Elettrika

Soluzzjoni għal kuntatt fqir ta 'wajer ta' reżistenza ta 'elementi ta' tisħin tubulari elettriku

Fil-proċess li tuża l-element ta 'tisħin, jekk il-wajer tar-reżistenza fit-tubu jinħaraq u l-wajer tat-tisħin ikun f'kuntatt fqir, kif issolvih?

(1) Metodu ta 'wajer ta' smash: Slott huwa ffurmat fl-aħħar tal-post taċ-ċomb, twil 15 mm, żewġ - terzi tad-dijametru, u l-wisa 'tista' titqiegħed fil-wajer tat-tisħin fit-tubu tat-tisħin. L-eħfef mod huwa li tnaqqas il-kanal ma 'xafra tas-serrieq, poġġi l-wajer tat-tisħin fil-kanal, tolqot ħafif iż-żewġ naħat tal-kanal, u agħfas sewwa l-wajer tat-tisħin; jekk possibbli, iwweldja t-tarf tal-wajer tar-reżistenza mal-post taċ-ċomb, dan l-effett huwa aħjar.

(2) Riveting and pressing method: The electric resistance wire and the lead column in the electric tubular heater are riveted together with a stainless steel capillary. Note that when riveting, the focus should be 2mm away from the capillary opening to prevent the heating wire from being injured.

(3) Insertion method: Insert the spiral coil of the resistance wire in the electric heating element into the end of the lead post for about 8 turns. If the end of the lead post has threads, you can screw it into the thread and then weld two points with a spot welding machine. Note that the electrode of the spot welding machine should be 3mm away from the end of the wire post to prevent the resistance wire from being injured.

Il-fatturi ewlenin li jiddeterminaw id-dijametru ta 'barra tal-coil tal-wajer tar-reżistenza fl-element ta' tisħin elettriku tubulari huma dawn:

(1) Insulation distance and insulation resistance

(2) Heat conduction

(3) Uneven resistance drop rate

L-effett tat-tisħin fuq l-uniformità ta 'l-element ta' tisħin elettriku jinkludi prinċipalment it-tliet punti li ġejjin:

(1). The heating length of the resistance wire in the heating elements: After the heating element is added with magnesium oxide powder, the position of the heating wire in the tube determines the future heating length of the product, so it must be processed in strict accordance with the design requirements.

(2). Tiżgura l-konċentriċità tal-elementi tat-tisħin tubulari u tal-kateter mit-tagħmir tal-produzzjoni: Peress li l-konċentrikità tal-wajer tat-tisħin u tat-tubu hija ggarantita mill-kateter, l-ewwelnett, il-konċentrikità tal-pajp u l-kateter huwa ggarantit mit-tagħmir tal-produzzjoni. biex tnaqqas l-uniformità tat-Temperatura mhux - fid-direzzjoni trasversali.

(3). The amplitude of the electromagnetic vibration table of the electric heating element cannot exceed a certain limit.
