Pour tout syst\u00e8me hydraulique, les fluides sont le composant le plus critique\u00a0!\u00a0<\/span><\/p>\n

\"hydraulic<\/p>\n

Pour les applications hydrauliques, le principal \u00e9l\u00e9ment distinctif est la pr\u00e9sence de fluides, ce qui est le cas de l'hydraulique et de la pneumatique. Le fluide hydraulique est \u00e9galement n\u00e9cessaire pour chaque op\u00e9ration dans un syst\u00e8me hydraulique.<\/span><\/p>\n

To move energy from one area of the system to another, hydraulic systems require incompressible hydraulic fluids, often known as hydraulic oils<\/a> or liquids. Fluids are kept in a reservoir and are sucked up by a pump that moves them through the pipes to other components during hydraulic system operation.<\/span><\/p>\n

In addition to choosing the right type of hydraulic fluid, keeping the fluid level within the recommended range is essential for performance and safety. Issues caused by low hydraulic fluid symptoms<\/strong><\/a>\u2014such as overheating, sluggish operation, pump damage, or full system failure\u2014can quickly escalate if not addressed. Operators should regularly check fluid levels and fix any leaks before they become costly repairs.<\/p>\n

Caract\u00e9ristiques d'un grand fluide hydraulique<\/strong><\/h2>\n

1. Viscosit\u00e9<\/b><\/h3>\n

The viscosity of hydraulic fluid<\/a> measures flows resistance. It is the essential property of hydraulic fluid and substantially impacts the system’s performance.<\/span><\/p>\n

L'\u00e9tanch\u00e9it\u00e9 est compromise lorsque l'huile hydraulique est trop fluide ou visqueuse. En cons\u00e9quence, il existe un risque de fuites et d'usure des pi\u00e8ces. La viscosit\u00e9 de l'huile hydraulique fait r\u00e9f\u00e9rence \u00e0 la difficult\u00e9 de pomper \u00e0 travers le syst\u00e8me, ce qui peut nuire aux performances.<\/span><\/p>\n

2. Compressibilit\u00e9<\/b><\/h3>\n

La compressibilit\u00e9 indique combien de volume est r\u00e9duit lorsqu'il est soumis \u00e0 une contrainte. Une l\u00e9g\u00e8re perte de volume peut se produire m\u00eame si les huiles hydrauliques sont essentiellement incompressibles.<\/span><\/p>\n

3. R\u00e9sistance \u00e0 la d\u00e9t\u00e9rioration<\/b><\/h3>\n

Hydraulic fluid can minimize the rate at which it wears out in frictional boundary contact. Metal surfaces can be shielded against abrasion, scuffing, and contact fatigue with the antiwear components found in antiwear hydraulic fluids<\/a>. Improved lubricant performance and longer equipment life can be achieved by using antiwear additives.<\/span><\/p>\n

4. Stabilit\u00e9 de l'oxydation<\/b><\/h3>\n

Heat-induced deterioration is caused by chemical reactions between oxygen and hydraulic oil. Additives that prevent oxidation<\/a>, increase the fluid’s stability, and extend its life are required in hydraulic oils. You should expect the hydraulic oil to lose its quality rapidly if you don’t use these additions.<\/span><\/p>\n

5. Stabilit\u00e9 \u00e0 la chaleur<\/b><\/h3>\n

La stabilit\u00e9 thermique fait r\u00e9f\u00e9rence \u00e0 la capacit\u00e9 d'un mat\u00e9riau \u00e0 r\u00e9sister \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es sans se d\u00e9grader. A des temp\u00e9ratures croissantes, la d\u00e9gradation des additifs anti-usure est acc\u00e9l\u00e9r\u00e9e. La boue et le vernis peuvent obstruer les filtres, r\u00e9duire le d\u00e9bit et allonger les temps d'arr\u00eat en raison de la stabilit\u00e9 \u00e0 basse temp\u00e9rature.<\/span><\/p>\n

6. Filtrabilit\u00e9<\/b><\/h3>\n

Les additifs de fluide hydraulique peuvent r\u00e9agir avec l'eau pour produire une substance insoluble dans l'huile. Ces impuret\u00e9s peuvent pr\u00e9cipiter du lubrifiant et obstruer le flux d'huile ou provoquer le contournement du syst\u00e8me. Un temps d'arr\u00eat impr\u00e9vu est une possibilit\u00e9 si un blocage persiste. La filtration des fluides hydrauliques dans les syst\u00e8mes modernes ne pr\u00e9sente aucune menace pour l'additif en raison de la conception des fluides.<\/span><\/p>\n

7. Anti-corrosion et pr\u00e9vention de la rouille<\/b><\/h3>\n

L'eau peut interagir avec l'huile hydraulique dans de nombreux syst\u00e8mes par condensation ou contamination. Les composants hydrauliques peuvent se corroder s'ils entrent en contact avec de l'eau. En prime, certains additifs peuvent r\u00e9agir avec l'eau pour g\u00e9n\u00e9rer des esp\u00e8ces chimiques qui peuvent endommager les m\u00e9taux jaunes lorsqu'ils sont combin\u00e9s. Dans les compositions d'huile hydraulique, les inhibiteurs de corrosion et de rouille emp\u00eachent l'eau et d'autres esp\u00e8ces chimiques d'interagir avec les surfaces m\u00e9talliques.<\/span><\/p>\n

8. La r\u00e9silience de la mousse<\/b><\/h3>\n

Lorsque de l'air ou d'autres gaz sont entra\u00een\u00e9s dans le fluide hydraulique, il mousse. Le r\u00e9servoir ou les fuites d'air \u00e0 l'int\u00e9rieur du syst\u00e8me hydraulique sont les deux principaux points d'entr\u00e9e de l'air dans le syst\u00e8me.<\/span><\/p>\n

Large amounts of dissolved or distributed air bubbles can be found in hydraulic fluids under high pressure. Depressurization causes bubbles to expand and create Foam. Foam can significantly impact machinery performance and lubrication due to its compressibility and poor lubricating characteristics. Because they reduce air bubble surface tension, suitable foam inhibitors<\/a> help break up Foam faster.<\/span><\/p>\n

9. D\u00e9s\u00e9mulsibilit\u00e9<\/b><\/h3>\n

L'huile hydraulique peut \u00e9mulsifier ou se combiner avec l'eau qui p\u00e9n\u00e8tre dans le syst\u00e8me. L'utilisation de ce fluide \u00ab humide \u00bb peut entra\u00eener de la corrosion et de la rouille s'il circule dans le syst\u00e8me. Les huiles min\u00e9rales qui ont \u00e9t\u00e9 consid\u00e9rablement raffin\u00e9es permettent \u00e0 l'eau de se s\u00e9parer ou de se d\u00e9s\u00e9mulsionner plus facilement. Les huiles hydrauliques, d'autre part, contiennent souvent des additifs qui provoquent la formation d'une \u00e9mulsion, emp\u00eachant l'eau de se dissoudre et de se d\u00e9poser dans le fluide.<\/span><\/p>\n

 <\/p>\n

Top 5 de l'importance du fluide hydraulique<\/b><\/h2>\n

Les huiles hydrauliques ont un impact significatif sur la productivit\u00e9 du syst\u00e8me. Les syst\u00e8mes hydrauliques sont souvent con\u00e7us pour des applications \u00e0 grande vitesse, haute pression et haute temp\u00e9rature. Une d\u00e9faillance pr\u00e9matur\u00e9e du syst\u00e8me peut \u00eatre \u00e9vit\u00e9e en analysant et en entretenant ad\u00e9quatement l'huile.<\/span><\/p>\n

La t\u00e2che \u00e0 accomplir d\u00e9termine le type de fluide hydraulique utilis\u00e9. Le fluide hydraulique parfait a quelques caract\u00e9ristiques. Par exemple, la lubrification et la d\u00e9ductibilit\u00e9 (la capacit\u00e9 de lib\u00e9rer de l'eau), la stabilit\u00e9 chimique et environnementale\u00a0; r\u00e9sistance au feu; faible inflammabilit\u00e9; r\u00e9sistance \u00e0 la mousse\u00a0; faible volatilit\u00e9, etc., sont tous inclus.\u00a0<\/span><\/p>\n

1. Production d'\u00e9nergie<\/b><\/h3>\n

Le principe du triangle de Pascal sous-tend le fonctionnement de tout syst\u00e8me hydraulique. Pour qu'un processus soit termin\u00e9, un fluide incompressible doit \u00eatre pr\u00e9sent dans le syst\u00e8me qui peut transmettre de l'\u00e9nergie d'un endroit \u00e0 un autre. Au point de limitation, la pression s'accumule en raison du d\u00e9bit initi\u00e9 par la pompe. La multiplication de la force et le contr\u00f4le dans n'importe quelle direction sont \u00e9galement des options.<\/span><\/p>\n

2. \u00c9liminer les contaminants<\/b><\/h3>\n

Pour \u00e9viter d'endommager le syst\u00e8me ou de r\u00e9duire la productivit\u00e9, \u00e9liminez tous les polluants \u00e9ventuellement pr\u00e9sents. Les particules solides ou l'eau peuvent \u00eatre utilis\u00e9es comme polluants. Les fluides hydrauliques jouent un r\u00f4le essentiel dans l'\u00e9limination de ces polluants du syst\u00e8me. Tous les corps \u00e9trangers sont transport\u00e9s par le fluide vers le filtre.<\/span><\/p>\n

3. Lubrification et protection<\/b><\/h3>\n

Pour \u00e9viter les pannes et l'usure pr\u00e9matur\u00e9es, une lubrification appropri\u00e9e doit \u00eatre appliqu\u00e9e. Il y a beaucoup de frottement si les pi\u00e8ces des composants hydrauliques (pompes, moteurs, vannes, etc.) sont constamment en mouvement. En formant un rev\u00eatement lubrifiant entre les pi\u00e8ces mobiles, les fluides hydrauliques peuvent minimiser la friction.<\/span><\/p>\n

4. \u00c9tanch\u00e9it\u00e9<\/b><\/h3>\n

La plupart des syst\u00e8mes hydrauliques comprennent des joints pour emp\u00eacher les fuites et les particules \u00e9trang\u00e8res de p\u00e9n\u00e9trer dans le syst\u00e8me. N\u00e9anmoins, les composants hydrauliques, tels que les vannes de r\u00e9gulation, fonctionneront dans des espaces tr\u00e8s compacts. Les fluides hydrauliques entre les pi\u00e8ces m\u00e9caniques serviront \u00e9galement de produits d'\u00e9tanch\u00e9it\u00e9.<\/span><\/p>\n

5. Transfert de chaleur<\/b><\/h3>\n

La surchauffe est caus\u00e9e par le frottement entre les pi\u00e8ces mobiles et la surface m\u00e9tallique. Le refroidissement par rayonnement est assur\u00e9 par un fluide en circulation.<\/span><\/p>\n

 <\/p>\n

Conclusion<\/b><\/h2>\n

Many mobile and stationary machinery run on hydraulic fluid. It’s impossible to overstate the importance of protecting this valuable medium. While a quality fluid has been built and designed to execute complex duties<\/a>, it cannot make up for a system with a small reservoir or a motor with a high shaft load, which must also be considered. In a well-designed hydraulic system, the good quality hydraulic fluid<\/a> serves the vital function of connecting the pump and actuator and any components in between.<\/span><\/p>\n
