Le film est produit par mouvement relatif. Cela signifie que le syst\u00e8me lui-m\u00eame exerce une pression sur ce type de lubrification.<\/li>\n<li><strong>Lubrification hydrostatique<\/strong><br \/>\nHydrostatic lubrication is so named because the moving parts&#8217; motion precludes the oil film&#8217;s formation, as suggested by the term. As a result, a separate oil pump is required to supply the necessary oil pressure. The effectiveness of <a href=\"https:\/\/www.bioblend.com\/fr\/industries\/marine\/\">marine lubrication<\/a> is determined by the clearance located on metal surfaces and the oil pressure at the entrance.<br \/>\nUne pompe de lubrification de traverse augmente la pression du lubrifiant hydrostatique utilis\u00e9 dans les paliers de traverse.<\/li>\n<li><strong>Lubrification des fronti\u00e8res<\/strong><br \/>\nCela arrive chaque fois qu&#039;il est impossible de faire un film enti\u00e8rement fait de fluide. Pour cr\u00e9er le film mince, deux surfaces mobiles doivent \u00eatre rapproch\u00e9es l&#039;une de l&#039;autre. Un frottement \u00e9lev\u00e9 entre ces surfaces indique un certain degr\u00e9 de contact m\u00e9tal sur m\u00e9tal.<br \/>\nUn arbre d\u00e9centr\u00e9, une vitesse lente ou une charge lourde peuvent tous provoquer ce ph\u00e9nom\u00e8ne. De plus, la faible viscosit\u00e9 de l&#039;huile pourrait \u00eatre \u00e0 bl\u00e2mer.<\/li>\n<li><strong>Pour lubrifier \u00e9lastiquement et dynamiquement<\/strong><br \/>\nLorsqu&#039;une d\u00e9formation \u00e9lastique importante des surfaces se produit, le film lubrifiant de la zone de contact change de forme et d&#039;\u00e9paisseur, un ph\u00e9nom\u00e8ne connu sous le nom de lubrification \u00e9lastohydrodynamique (EHD). Cela se produit g\u00e9n\u00e9ralement lorsque deux surfaces mobiles se touchent, soit par roulement, soit par glissement.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>Syst\u00e8mes de lubrification de moteurs marins<\/strong><\/h2>\n<ul>\n<li><strong>Syst\u00e8me de lubrification principal<\/strong><br \/>\nDeux pompes sont utilis\u00e9es dans le syst\u00e8me de lubrification du carter. Une pompe fonctionnera en continu, tandis que l&#039;autre sera en r\u00e9serve. Si la pression d&#039;huile chute ou si la pompe primaire tombe en panne, elle s&#039;enclenche.<br \/>\nUn tube t\u00e9lescopique transporte l&#039;huile jusqu&#039;\u00e0 la traverse. \u00c0 ce stade, il se d\u00e9place vers le moteur principal et lubrifie diverses pi\u00e8ces mobiles. Le piston est refroidi et lubrifi\u00e9 en premier lieu. Le palier de la traverse est le prochain arr\u00eat.<\/li>\n<li><strong>Syst\u00e8mes de lubrification du turbocompresseur avec de l&#039;huile<\/strong><br \/>\nUn turbocompresseur est un exemple de composant qui tourne tr\u00e8s rapidement dans un moteur. Utilisez les gaz d&#039;\u00e9chappement du moteur de votre bateau pour alimenter la turbine. La fonction premi\u00e8re de la prise d&#039;air du moteur marin est d&#039;alimenter la combustion en air oxyg\u00e9n\u00e9.<br \/>\nLes roulements d&#039;un turbocompresseur sont mont\u00e9s sur l&#039;arbre, qui tourne \u00e0 grande vitesse et supporte relativement facilement de lourdes charges.<\/li>\n<li><strong>Syst\u00e8me de lubrification des cylindres<\/strong><br \/>\nLa lubrification des cylindres est assur\u00e9e par son syst\u00e8me d\u00e9di\u00e9. La lubrification des segments de piston est ainsi rendue possible. Les fonctions du syst\u00e8me de lubrification des cylindres sont multiformes, notamment\u00a0:<\/p>\n<ul>\n<li>Diminution de la r\u00e9sistance entre les anneaux et le liner.<\/li>\n<li>Sceller ces pi\u00e8ces ensemble pour \u00e9viter tout dommage<\/li>\n<li>Prot\u00e9ger contre la rouille, pour commencer.<\/li>\n<li>Il nettoie \u00e9galement les impuret\u00e9s dans les huiles et le gaz.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>Choisir le meilleur lubrifiant marin<\/strong><\/h2>\n<p>Les pi\u00e8ces des moteurs marins sont vuln\u00e9rables aux effets du frottement, de la corrosion et de l&#039;usure, quelle que soit l&#039;intensit\u00e9 du moteur. Leur sensibilit\u00e9 accrue \u00e0 l&#039;usure est due \u00e0 l&#039;augmentation de la friction, de la corrosion et de l&#039;utilisation g\u00e9n\u00e9rale.<\/p>\n<p>Assurez-vous que le moteur reste bien huil\u00e9 afin qu&#039;il puisse fonctionner de mani\u00e8re fiable.<br \/>\nSa configuration de lubrification peut soit \u00eatre int\u00e9gr\u00e9e au primaire du moteur, soit fonctionner s\u00e9par\u00e9ment.<\/p>\n<p>Here are some qualities of <a href=\"https:\/\/www.bioblend.com\/fr\/produit\/bioblend-mpo\/\">an efficient marine engine lubrication oil<\/a> that will ensure the turbocharger bearing lubrication system is adequately protected:<\/p>\n<ul>\n<li><strong>Viscosit\u00e9 de l&#039;huile<\/strong><br \/>\nLa viscosit\u00e9 de l&#039;huile indique son \u00e9paisseur et sa fluidit\u00e9 \u00e0 diff\u00e9rentes temp\u00e9ratures. L&#039;huile \u00e0 haute viscosit\u00e9 est tr\u00e8s \u00e9paisse. \u00c0 des temp\u00e9ratures \u00e9lev\u00e9es, le rev\u00eatement \u00e9pais form\u00e9 par ces lubrifiants autour des composants du moteur est plus efficace pour le prot\u00e9ger des dommages. \u00c0 l&#039;inverse, les huiles \u00e0 faible viscosit\u00e9 sont plus fluides car elles ont une teneur en solides plus faible.<\/li>\n<li><strong>Alcalinit\u00e9<\/strong><br \/>\nL&#039;acide sulfurique, lib\u00e9r\u00e9 lors de la combustion du combustible, peut entra\u00eener une corrosion acide. Une alcalinit\u00e9 \u00e9lev\u00e9e dans l&#039;huile est cruciale pour les moteurs marins car elle emp\u00eache la corrosion acide.<\/li>\n<li><strong>R\u00e9sister \u00e0 l&#039;oxydation<\/strong><br \/>\nLubricants in marine engines have air contact. For this reason, oxygen must always be present. Oxidation rates increase at high temperatures, leading to sludge development, bearing corrosion, and acid production. For this reason, lubricating oils typically contain <a href=\"https:\/\/www.bioblend.com\/fr\/when-to-use-hydraulic-fluid-additives\/\">anti-oxidation and anti-corrosion compounds<\/a>.<\/li>\n<li><strong>Capacit\u00e9 de porter du poids<\/strong><br \/>\nEn effet, la viscosit\u00e9 de l&#039;huile affecte le poids qu&#039;elle peut transporter. Les composants internes du moteur marin sont relativement lourds. Par cons\u00e9quent, la capacit\u00e9 de charge du lubrifiant doit \u00eatre suffisante pour maintenir la pression du moteur. \u00c9vitez de le faire, car cela pourrait acc\u00e9l\u00e9rer l&#039;usure du moteur en raison de la friction accrue entre les pi\u00e8ces m\u00e9talliques.<br \/>\nUn point de style majeur<br \/>\nIl mesure le froid qu&#039;il doit parcourir avant que le lubrifiant ne s&#039;\u00e9vapore. Dans tous les cas, elle doit \u00eatre sup\u00e9rieure \u00e0 220 degr\u00e9s Celsius. Ainsi, le risque d&#039;incendie est diminu\u00e9 \u00e0 mesure que la temp\u00e9rature de l&#039;huile augmente.<\/li>\n<li><strong>D\u00e9tergence<\/strong><br \/>\nLes additifs d\u00e9tergents \u00e0 base de m\u00e9tal ont des qualit\u00e9s de nettoyage sup\u00e9rieures et sont ajout\u00e9s au m\u00e9lange. En cons\u00e9quence, ils gardent les surfaces m\u00e9talliques exemptes de poussi\u00e8re et de salet\u00e9. Ils nettoient la chambre de combustion des moteurs \u00e0 deux temps en \u00e9liminant les d\u00e9bris du pack de bagues.<\/li>\n<li><strong>Stabilit\u00e9 thermodynamique<\/strong><br \/>\nThe engine&#8217;s working elements generate heat continuously. The oil must absorb the heat&#8217;s thermal energy to keep the marine engine from overheating. It should be <a href=\"https:\/\/www.bioblend.com\/fr\/produit\/bioflo-aw\/\">thermally stable and have strong conductivity<\/a> because it cools down the engine&#8217;s interior components.<\/li>\n<\/ul>\n<h2>Conclusion<\/h2>\n<p>Marine engines demand exceptional lubrication to withstand challenging conditions and ensure optimal performance.
