Le tuyau ne doit pas supporter la force axiale, ce qui endommagerait la connexion entre le joint et le tuyau.<\/p>\n\n\n\n<p>Le frottement entre le tuyau et le tuyau ou entre le tuyau et le corps peut causer des dommages locaux au tuyau, entra\u00eenant la rouille de la couche de fil d'acier expos\u00e9e et une diminution de la r\u00e9sistance \u00e0 la pression, ce qui conduira finalement \u00e0 l'\u00e9clatement du tuyau.

Une fois le tuyau rinc\u00e9, utilisez une housse ou un sac en plastique pour sceller les deux extr\u00e9mit\u00e9s du tuyau. Une fois le tuyau rinc\u00e9, les extr\u00e9mit\u00e9s du tuyau sont scell\u00e9es \u00e0 l'aide de capuchons ou de sacs en plastique. Enfin, le tuyau est plac\u00e9 dans la bo\u00eete de stockage pour \u00e9viter que la poussi\u00e8re ne provoque une contamination secondaire. Deuxi\u00e8me contamination. Il faut toujours pr\u00e9lever des \u00e9chantillons pour tester le degr\u00e9 de contamination de l'huile hydraulique \u00e0 des fins de nettoyage. Le degr\u00e9 de contamination des particules d'huile hydraulique doit \u00eatre conforme \u00e0 la norme NAS9. <\/p>\n\n\n\n<p>Lors du nettoyage des tuyaux, il est n\u00e9cessaire de porter des gants m\u00e9dicaux ou des gants en caoutchouc r\u00e9sistant \u00e0 l'huile pour \u00e9viter de contaminer le syst\u00e8me hydraulique.<\/p>","protected":false},"excerpt":{"rendered":"<p>The installation and cleaning of hydraulic hoses requires professional operation, improper operation will reduce the service life of the hoses, please be careful.
