Lorsqu'une table \u00e0 fibre laser d\u00e9coupe de l'acier inoxydable \u00e0 30 bars, chaque pied cube de gaz compte. C'est pourquoi le choix de la bonne compresseur pour l'azote de d\u00e9coupe laser<\/strong> est la cl\u00e9 de la qualit\u00e9 de coupe, de la dur\u00e9e de vie des buses et du co\u00fbt de l'\u00e9nergie.

\n

1\ufe0f\u20e3 Commencez par la pression et le d\u00e9bit<\/h3>\n

Les manuels des \u00e9quipementiers laser sp\u00e9cifient la pression du gaz d'assistance en fonction de l'\u00e9paisseur :<\/p>\n

Tout d'abord, ajoutez 10 % pour les pertes de ligne. Ce chiffre corrig\u00e9 vous indique si vous avez besoin d'un compresseur d'azote<\/strong> seul ou un g\u00e9n\u00e9rateur d'azote \u00e0 haute pression et surpresseur<\/strong>.<\/p>\n

\n

2\ufe0f\u20e3 Adapter la technologie du compresseur au cycle de travail<\/h3>\n

KPL-75 de Keepwin\u00a0compresseur \u00e0 vis<\/strong> produit 12 m\u00b3 \/ min \u00e0 13 bar ; associ\u00e9 \u00e0 un booster de 40 bar, il alimente simultan\u00e9ment trois t\u00eates laser de 6 kW.<\/p>\n

\n

3\ufe0f\u20e3 Envisager un g\u00e9n\u00e9rateur d'azote \u00e0 haute pression<\/h3>\n

La production de gaz sur place permet de r\u00e9duire les co\u00fbts des bouteilles jusqu'\u00e0 80 %. A g\u00e9n\u00e9rateur d'azote \u00e0 haute pression<\/strong> Les sorties de 40 \u00e0 50 bars sont directes, de sorte que le surpresseur travaille moins, ce qui permet d'\u00e9conomiser de l'\u00e9nergie et de la chaleur. Choisissez le PSA si une puret\u00e9 sup\u00e9rieure \u00e0 99,9 % est obligatoire ; choisissez la membrane pour une puret\u00e9 de 95-99 % avec une \u00e9nergie plus faible.<\/p>\n

\n

4\ufe0f\u20e3 Taille pour SCFM, pas seulement pour le bar<\/h3>\n

Le d\u00e9bit en SCFM varie en fonction de la puret\u00e9. Les coupes plus \u00e9paisses n\u00e9cessitent plus d'azote par seconde. Utilisez cette r\u00e8gle rapide :<\/p>\n

SCFM=Diam\u00e8tre de la buse (mm)2\u00d7Pression (psi)50\\text{SCFM} = \\frac{\\text{diam\u00e8tre de la buse (mm)}^{2} \\contre \\text{Pression (psi)}}{50}<\/span>SCFM<\/span><\/span>=<\/span><\/span>50Diam\u00e8tre de la buse (mm)<\/span>2<\/span><\/span><\/span><\/span>\u00d7<\/span>Pression (psi)<\/span><\/span>\u200b<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

V\u00e9rifier avec les tableaux de l'OEM, puis arrondir \u00e0 10 % pour assurer la p\u00e9rennit\u00e9 de la capacit\u00e9.<\/p>\n

\n

5\ufe0f\u20e3 V\u00e9rifier l'efficacit\u00e9 \u00e9nerg\u00e9tique et le rejet de la chaleur<\/h3>\n

Les compresseurs convertissent 80 % des kW d'entr\u00e9e en chaleur. Capturez-la avec un \u00e9changeur de chaleur \u00e0 plaques et pr\u00e9chauffez l'eau de traitement. Keepwin int\u00e8gre des kits de r\u00e9cup\u00e9ration de chaleur qui s'amortissent en moins de douze mois.<\/p>\n

\n

6\ufe0f\u20e3 Contr\u00f4les intelligents de la demande<\/h3>\n

Les ateliers laser modernes changent d'\u00e9paisseur toute la journ\u00e9e. Un PLC avec VFD ajuste la vitesse du moteur en quelques millisecondes, en maintenant la pression \u00e0 \u00b10,3 bar. La r\u00e9duction des cycles de d\u00e9chargement se traduit par une usure moindre et des sols plus silencieux.<\/p>\n

\n

7\ufe0f\u20e3 V\u00e9rifier le service apr\u00e8s-vente et les pi\u00e8ces d\u00e9tach\u00e9es<\/h3>\n

Un laser peut fonctionner 6 000 heures par an ; les temps d'arr\u00eat co\u00fbtent cher. Keepwin fournit des pi\u00e8ces d\u00e9tach\u00e9es dans le monde entier dans un d\u00e9lai de 72 heures et propose des diagnostics \u00e0 distance via des modules 4G, ce qui est essentiel pour les usines en panne d'\u00e9lectricit\u00e9.<\/p>\n
