L'hydraulique peut \u00eatre trouv\u00e9e au travail comme un moyen efficace de g\u00e9n\u00e9rer de l'\u00e9nergie m\u00e9canique. L'action hydraulique, dans sa forme la plus simple, est l'utilisation d'un fluide comprim\u00e9 pour effectuer un mouvement.<\/span><\/p>\n

\"What<\/p>\n

Les ascenseurs, les machines de construction, les amortisseurs, les freins, la direction assist\u00e9e et m\u00eame les syst\u00e8mes de direction des engins spatiaux utilisent tous l'hydraulique. Du fait de la lev\u00e9e importante de ce syst\u00e8me, tout <\/span>fluide hydraulique<\/a> fuites doit \u00eatre corrig\u00e9 au plus vite !<\/span><\/p>\n

 <\/p>\n

9 Helpful Tips on Fixing Hydraulic Fluid Leaks<\/b><\/h2>\n

L'emplacement d'une fuite doit alors \u00eatre d\u00e9termin\u00e9. Pour cela, retirez la pression du syst\u00e8me et examinez les joints, les connecteurs et les joints \u00e0 l'aide de gants de protection.\u00a0<\/span><\/p>\n

Les raccords et raccords qui fuient peuvent souvent \u00eatre r\u00e9par\u00e9s en les serrant simplement. Il peut \u00eatre n\u00e9cessaire de remplacer les joints et les flexibles us\u00e9s.<\/span><\/p>\n

Astuce 1 : Si vous trouvez une fuite, r\u00e9parez-la le plus rapidement possible.<\/b><\/h3>\n

Une fuite ext\u00e9rieure est \u00e9vidente \u00e0 l'\u0153il nu. Ne le mettez plus. Une fuite dans votre syst\u00e8me hydraulique peut laisser pr\u00e9sager un probl\u00e8me plus important affectant les performances et l'efficacit\u00e9. Trouvez une solution rapide au probl\u00e8me.<\/span><\/p>\n

Astuce 2 : Utilisez toujours des gants de protection lorsque vous manipulez du fluide hydraulique.<\/b><\/h3>\n

\u00c9vitez d'utiliser votre main nue pour trouver des fuites. Des br\u00fblures caus\u00e9es par un fluide hydraulique \u00e0 300\u00a0\u00b0F ou plus peuvent survenir en quelques minutes. Les fuites de liquides \u00e0 grande vitesse peuvent \u00eatre d\u00e9vastatrices si elles touchent votre main. Cette blessure n\u00e9cessite un traitement m\u00e9dical imm\u00e9diat, peut entra\u00eener une amputation et enfreint les r\u00e8gles de s\u00e9curit\u00e9. Il faut se m\u00e9fier.<\/span><\/p>\n

Astuce 3 : S'il y a une fuite, aucune flamme ne doit l'entourer.<\/b><\/h3>\n

Assurez-vous toujours de garder tout type de flamme au moins \u00e0 une distance de s\u00e9curit\u00e9 de tout type de point de fuite. Malheureusement, des nuages de vapeur combustible peuvent \u00eatre produits m\u00eame par les fuites les plus mineures, qui sont souvent n\u00e9glig\u00e9es.\u00a0<\/span><\/p>\n

Astuce 4 : Baissez la pression dans le syst\u00e8me.<\/b><\/h3>\n

Pressure must be removed before checking a hydraulic system. It can remain even if liquids flow slowly. Depressurizing the system reduces the chance of hydraulic fluid bursting during the examination. After shutting down, trapped fluid and back pressure may remain. Even when the system is off, use caution.<\/span><\/p>\n

Astuce 5 : Assurez-vous toujours que votre lubrification est \u00e0 la hauteur.<\/b><\/h3>\n

Les lubrifiants contamin\u00e9s causent 80% de pannes de machines et d'\u00e9quipements. La surchauffe provoque une oxydation, et la salet\u00e9, l'eau et les m\u00e9taux us\u00e9s provoquent une contamination et des fuites. Un raccord tomb\u00e9 avant le remontage pourrait polluer le syst\u00e8me hydraulique.\u00a0<\/span><\/p>\n

Astuce 6 : Vous devez nettoyer vos prises et connecteurs<\/b><\/h3>\n

Avant de remplacer un raccord, nettoyez les extr\u00e9mit\u00e9s. Il maintient le syst\u00e8me hydraulique propre. Une rondelle conique peut emp\u00eacher les joints \u00e9vas\u00e9s de fuir. L'utilisation de raccords filet\u00e9s avec un joint en \u00e9lastom\u00e8re assurera l'\u00e9tanch\u00e9it\u00e9 \u00e0 l'eau.<\/span><\/p>\n

Astuce 7 : Changez les joints toriques et autres raccords si n\u00e9cessaire.<\/b><\/h3>\n

M\u00eame si vous remontez un raccord r\u00e9utilisable, vous devez toujours remplacer les joints toriques. Un joint torique endommag\u00e9 ne fournira plus une \u00e9tanch\u00e9it\u00e9 fiable apr\u00e8s avoir \u00e9t\u00e9 remont\u00e9. Le remplacement d'un raccord est toujours plus rentable que l'achat d'une machine neuve.<\/span><\/p>\n

Astuce 8 : Utilisez toujours le bon couple de serrage lors du serrage.<\/b><\/h3>\n

If the torque applied to a flare joint is too low, the seat won’t make contact with the tube, and if it’s too high, the connector and tube could be damaged. Over- or under-torquing a compression joint might cause the ferrule to “crush” too much or too little. From time to time, a fluid leak can be traced down to a simple cause: a nut that has come loose. To fix this, simply snug up the nut.\u00a0<\/span><\/p>\n

Astuce 9 : \u00c9tablissez une routine d'entretien.<\/b><\/h3>\n

There is a correlation between hose and fitting inspections and the frequency of unexpected problems. Ensure there are no leaks, cracks, or blisters. Change the filters and wipe down the machines regularly. Keep an eye out for hydraulic dripping; if you see it, track down the source of the leak before it causes any severe damage or expense.<\/span><\/p>\n

 <\/p>\n

Tra\u00e7age efficace des fuites de fluide hydraulique<\/b><\/h2>\n

Inspections fr\u00e9quentes<\/b><\/h3>\n

Chaque machine doit faire v\u00e9rifier ses fuites dans le cadre de son entretien r\u00e9gulier. Un contr\u00f4le visuel fera tr\u00e8s bien l'affaire. Allumez la machine, mettez-la \u00e0 la pression de fonctionnement, puis v\u00e9rifiez s'il y a des fuites ou des gouttes de liquide en inspectant visuellement tous les tuyaux et les points de connexion. Recherchez \u00e9galement des flaques d'eau ou d'autres endroits humides inhabituels sur le sol autour de la machine, car ils pourraient \u00eatre des signes d'une fuite ext\u00e9rieure.<\/span><\/p>\n

Surveillance des niveaux de liquide<\/b><\/h3>\n

Les fuites externes entra\u00eeneront une baisse des niveaux de liquide du syst\u00e8me\u00a0; ainsi, la surveillance de ces niveaux est une m\u00e9thode pr\u00e9cieuse pour rester inform\u00e9 de tout changement. Avoir des dossiers organis\u00e9s sera utile. La compr\u00e9hension de la quantit\u00e9 de liquide perdue du syst\u00e8me pendant le fonctionnement normal peut \u00eatre d\u00e9termin\u00e9e en notant quand et combien de liquide a \u00e9t\u00e9 r\u00e9approvisionn\u00e9 au fil du temps. Un aper\u00e7u de cela aidera \u00e0 d\u00e9tecter les \u00e9carts par rapport \u00e0 la norme, ce qui peut signaler la pr\u00e9sence d'une fuite dans le syst\u00e8me et n\u00e9cessiter une r\u00e9paration.<\/span><\/p>\n

Localisation de l'origine de la fuite hydraulique<\/b><\/h3>\n

Il peut \u00eatre difficile de localiser la source de la fuite si du liquide s'\u00e9coule d'autres zones de l'appareil. Par exemple, du liquide peut couler de la connexion du tuyau \u00e0 la valve, mais le tuyau lui-m\u00eame peut \u00eatre divis\u00e9 en deux, le liquide se d\u00e9pla\u00e7ant sur toute la longueur du tuyau avant de s'\u00e9goutter au niveau de la connexion.<\/span><\/p>\n

 <\/p>\n

Problems Caused by Hydraulic Fluid Leaks<\/b><\/h2>\n

Les fuites provenant de l'ext\u00e9rieur peuvent avoir des effets consid\u00e9rables, notamment sur les b\u00e9n\u00e9fices, le bien-\u00eatre des employ\u00e9s et la qualit\u00e9 de l'environnement. Plus particuli\u00e8rement, certains des probl\u00e8mes sont:<\/span><\/p>\n

1. Fluide consommable<\/b><\/h3>\n

A significant issue is fluid loss. Every time a drop is lost, it must be replaced at a cost.<\/span><\/p>\n

2. Produire de la chaleur<\/b><\/h3>\n

Inadequate fluid levels in the system can lead to overheating, varnish buildup, and early hose and seal failure. Maintaining a consistent temperature for hydraulic oil requires additional details.<\/span><\/p>\n

3. Pollution et autres dangers \u00e9cologiques<\/b><\/h3>\n

Les fuites de liquide des engins mobiles peuvent \u00eatre particuli\u00e8rement probl\u00e9matiques car elles risquent de polluer l'environnement et sont difficiles \u00e0 nettoyer. Les fuites petites ou d\u00e9couvertes causeront moins de dommages \u00e9cologiques, mais des fuites plus importantes peuvent avoir de graves cons\u00e9quences. Les incidents de glissade et de chute, toujours une source importante de blessures sur le lieu de travail, peuvent \u00eatre provoqu\u00e9s par l'huile hydraulique qui s'est accumul\u00e9e sur le sol dans les environnements industriels.<\/span><\/p>\n

4. Contamination toxique du syst\u00e8me<\/b><\/h3>\n

Les fuites externes forment des ponts entre le monde ext\u00e9rieur et le fluide hydraulique. Si la fissure est suffisamment grande, des particules peuvent p\u00e9n\u00e9trer dans l'espace laiss\u00e9 par le fluide. La contamination des fluides contribue de mani\u00e8re significative \u00e0 la d\u00e9t\u00e9rioration et \u00e0 la d\u00e9faillance \u00e9ventuelle des syst\u00e8mes hydrauliques. Il est indispensable lorsque la machine est utilis\u00e9e dans un environnement mobile, o\u00f9 elle est fr\u00e9quemment expos\u00e9e \u00e0 la salet\u00e9.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
