Que sont les joints \u00e0 ressort ?<\/b> <\/span><\/h2>\r\nLes joints \u00e0 ressort sont des joints \u00e0 l\u00e8vre qui int\u00e8grent un ressort m\u00e9tallique ou composite dans leur conception. Le ressort maintient une charge constante sur la l\u00e8vre du joint, compensant l\u2019usure, la dilatation et la contraction thermiques, ainsi que le d\u00e9salignement. Ils sont g\u00e9n\u00e9ralement \u00e0 simple effet, fonctionnent dans des applications statiques et dynamiques, et doivent \u00eatre orient\u00e9s avec le ressort vers le c\u00f4t\u00e9 pression. <\/span> <\/span>\r\n\r\nLes joints \u00e9nergis\u00e9s par ressort sont principalement utilis\u00e9s dans des environnements extr\u00eames o\u00f9 les joints moul\u00e9s standards en thermoplastique ou en \u00e9lastom\u00e8re ne peuvent r\u00e9pondre aux exigences de l\u2019application. Cela peut inclure des applications impliquant des pressions \u00e9lev\u00e9es, des temp\u00e9ratures \u00e9lev\u00e9es ou cryog\u00e9niques, des milieux chimiquement agressifs, ou lorsqu\u2019une \u00e9tanch\u00e9it\u00e9 fiable \u00e0 faible friction est essentielle. Comme chaque application comporte des exigences de performance diff\u00e9rentes, Hi-Tech Seals fournit principalement des joints \u00e9nergis\u00e9s par ressort con\u00e7us sur mesure. <\/span> <\/span>\r\n\r\nVeuillez consulter notre \u00e9tude de cas sur la mani\u00e8re dont nous avons soutenu les outils de t\u00e9l\u00e9m\u00e9trie de fond de puits p\u00e9troliers avec des joints \u00e0 ressort sp\u00e9cialis\u00e9s : <\/span>Joints \u00e0 ressort pour la t\u00e9l\u00e9m\u00e9trie de fond de puits p\u00e9troliers<\/span><\/b><\/a>.<\/span> <\/span>\r\n\r\nL\u2019installation des joints \u00e0 ressort peut souvent \u00eatre difficile. Pour cette raison, il est fortement recommand\u00e9 de les utiliser dans des conceptions \u00e0 gorge ouverte ou fendue. <\/span> <\/span>\r\n\r\n <\/span>\r\n
