Le meilleur package est rarement le grade unique le moins cher.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>D\u00e9faillance 1 : Apr\u00e8s la mise en marche de la machine, l'\u00e9cran de la fen\u00eatre CP2000 affiche une d\u00e9faillance du circuit d'huile, le voyant de signalisation de la d\u00e9faillance clignote.<\/p>\n<p>M\u00e9thode d'inspection : On a d'abord soup\u00e7onn\u00e9 que l'huile \u00e9tait moins abondante, mais le probl\u00e8me persiste apr\u00e8s le ravitaillement en carburant. V\u00e9rifiez le circuit d'huile et constatez que le filtre \u00e0 huile situ\u00e9 dans la partie sup\u00e9rieure de la cartouche est rouge, alors qu'il devrait \u00eatre vert dans des conditions normales. Retirer l'\u00e9l\u00e9ment filtrant pour le nettoyer et le r\u00e9installer, son indication sup\u00e9rieure est verte, la fen\u00eatre CP indique normal, la machine fonctionne normalement.

La mesure B12, 12 pieds pas de puissance, indiquant que la carte ne sort pas, donc la carte est soup\u00e7onn\u00e9e de dommages, et \u00e0 c\u00f4t\u00e9 du m\u00eame type de carte de circuit imprim\u00e9 (num\u00e9ro de carte SSK200.781.3764\/01BAU) interchangeable, le d\u00e9faut reste, indiquant que la carte n'est pas un probl\u00e8me. La tension de 1R4 est normale (10V entre les deux lignes de rouge et de couleur, 5,2V entre les deux lignes de rouge et de noir, et 4,8V entre les deux lignes de rouge et de noir), ce qui signifie que le potentiom\u00e8tre est normal, mais qu'il n'y a pas de tension continue de 24V \u00e0 1M4. Coupez l'alimentation totale de la machine, retirez le fil du moteur (fil rouge et fil de couleur composite) des bornes 1M4X1 \u00e0 1 et 2, et mesurez la r\u00e9sistance de 1M4 \u00e0 13,6f2 normal. Au d\u00e9but, le moteur ne tournait toujours pas, mais apr\u00e8s des pressions positives et n\u00e9gatives r\u00e9p\u00e9t\u00e9es, le moteur a commenc\u00e9 \u00e0 tourner petit \u00e0 petit, et finalement le moteur a fonctionn\u00e9 normalement sous l'effet de l'\u00e9lectricit\u00e9 appliqu\u00e9e et a entra\u00een\u00e9 la rotation de l'engrenage de r\u00e9glage. Ensuite, la ligne de couleur rouge, Xu dans les bornes 1M4X1 1, 2, refermer l'alimentation totale, puis essayer le moteur fonctionnent normalement, les param\u00e8tres de la fen\u00eatre CP et ajuster la valeur de la correcte, le num\u00e9rique ne sautent plus.<\/p>\n<p>Analyser la cause de la d\u00e9faillance susmentionn\u00e9e : lorsque la carte de circuit imprim\u00e9 fournit une tension de 24 V CC au moteur, la machine ne tourne pas, de sorte que la protection de sortie de la carte de circuit imprim\u00e9, de sorte que la tension ne peut pas \u00eatre mesur\u00e9e, de sorte que l'on consid\u00e8re que la carte de circuit imprim\u00e9 de commande est d\u00e9faillante. Le moteur n'est pas utilis\u00e9 pendant une longue p\u00e9riode, l'arbre, l'engrenage de connexion, la douille de dent, etc. sont aggrav\u00e9s par la charge m\u00e9canique due \u00e0 l'huile du corps, et la charge devient plus l\u00e9g\u00e8re apr\u00e8s une pressurisation positive et n\u00e9gative r\u00e9p\u00e9t\u00e9e, et alors la carte de circuit imprim\u00e9 SSK20 peut fonctionner normalement lorsqu'elle est aliment\u00e9e.<\/p>\n<p>D\u00e9faut 3 : le quatri\u00e8me groupe d'eau s\u00e9rie 4M1 moteur tourner quand ne pas tourner, parfois appuyer sur le bouton de l'eau forte 4S21 apr\u00e8s le moteur peut tourner \u00e2me pendant une p\u00e9riode de temps, et parfois CP fen\u00eatre alarme, la machine ne peut pas fonctionner normalement.<\/p>\n<p>M\u00e9thode d'inspection : le 4e groupe de fils de moteur I14M1 et le 3e groupe de moteurs de la s\u00e9rie Water s'\u00e9changent, afin de d\u00e9terminer si le moteur est bon ou mauvais ; 4M1 sera retir\u00e9, et la rotation m\u00e9canique ne pr\u00e9sentera pas de ph\u00e9nom\u00e8ne de blocage ; la carte de circuit imprim\u00e9 de contr\u00f4le de la machine auxiliaire de l'\u00e2me \u00e9lectrique de l'armoire \u00e9lectrique de l'eau, le 4e groupe et d'autres groupes de cartes de circuit imprim\u00e9 (num\u00e9ro de carte de circuit imprim\u00e9 LTK50000781.3680\/02) s'\u00e9changent. En g\u00e9n\u00e9ral, les m\u00e9thodes ci-dessus permettent de r\u00e9soudre ce type de panne, mais la panne de la machine est diff\u00e9rente : le moteur est normal, la carte de circuit imprim\u00e9 est intacte, la rotation m\u00e9canique est normale, et la connexion, la prise de courant, la prise de courant, ne pr\u00e9sentent aucun point de d\u00e9faillance. Dans le seau d'eau, il y a une d\u00e9tection de la pr\u00e9sence du capteur de liquide mouillant 4B32, l'inspection a r\u00e9v\u00e9l\u00e9 qu'il est parfois bon et parfois mauvais, nettoyer sa surface apr\u00e8s que la machine a travaill\u00e9 pendant un certain temps, puis la d\u00e9faillance mentionn\u00e9e ci-dessus. Enlever 4B32 avec une loupe, a trouv\u00e9 que le haut du capteur a une fissure, indiquant que le d\u00e9faut est ici, pour assurer la production premi\u00e8re sortie courte, la machine peut fonctionner, dans l'achat du m\u00eame type de remplacement de capteur apr\u00e8s la machine fonctionne normalement.<\/p>\n<p>D\u00e9faut 4 : Au moment de la coupure de courant, le changement de tension est trop \u00e9lev\u00e9, la carte de circuit d'alimentation (GRM120) sur la grande r\u00e9sistance chauffe, cuite \u00e0 c\u00f4t\u00e9 de la petite carte de circuit de d\u00e9tection (RSK120), de sorte que la machine ne fonctionne pas correctement, la fen\u00eatre CP2000 affiche le d\u00e9faut 15.<\/p>\n<p>M\u00e9thode d'inspection : v\u00e9rifier l'assurance GRM120 F3 normale, la grande r\u00e9sistance est normale, la tension de sortie est normale, mais le substrat RSK120 br\u00fbl\u00e9, l'original endommag\u00e9, a d\u00fb en acheter un nouveau, remplac\u00e9 la machine fonctionne normalement. Il convient de rappeler aux op\u00e9rateurs qu'en cas d'arr\u00eat, il faut attendre quelques minutes avant de fermer l'interrupteur principal de la machine, ce qui est tr\u00e8s bon pour les machines

m\u00e9langes de photoinitiateurs sont-ils si courants ?<\/strong><br \/>Parce qu'un produit peut contr\u00f4ler le jaunissement ou bien s'adapter \u00e0 la lampe, tandis qu'un autre am\u00e9liore la profondeur de durcissement ou les performances en vitesse de ligne, l'ensemble complet est souvent plus performant que n'importe quel grade individuel.<\/p>\n<p><strong>Une polym\u00e9risation incompl\u00e8te doit-elle toujours \u00eatre r\u00e9solue en ajoutant plus d'initiateur ?<\/strong><br \/>Pas automatiquement. La limitation r\u00e9elle peut \u00eatre la lampe, l'\u00e9paisseur du film, la teinte du pigment, ou le reste du syst\u00e8me r\u00e9actif plut\u00f4t qu'un simple sous-dosage.<\/p>\n<p><!-- lc-commercial-end --><\/p>\n<h2><strong><b>Contactez-nous d\u00e8s maintenant !<\/b><\/strong><\/h2>\n<h4><strong><b>Si vous avez besoin de COA, MSDS ou TDS, veuillez indiquer vos coordonn\u00e9es dans le formulaire ci-dessous.
