O \u00f3leo hidr\u00e1ulico, tamb\u00e9m chamado fluido hidr\u00e1ulico, \u00e9 um l\u00edquido incompress\u00edvel usado principalmente em cilindros pressurizados para transferir press\u00e3o e movimentar objetos. Possui diversas formula\u00e7\u00f5es e pode ser personalizado para uma ampla gama de aplica\u00e7\u00f5es e condi\u00e7\u00f5es de opera\u00e7\u00e3o. Embora o \u00f3leo hidr\u00e1ulico seja essencial para sistemas hidr\u00e1ulicos, ele tamb\u00e9m tem outras finalidades.\u00a0<\/span><\/p>\n O \u00f3leo hidr\u00e1ulico \u00e9 um fluido praticamente incompress\u00edvel que se destaca na transmiss\u00e3o de pot\u00eancia em um sistema. O tipo mais comum de \u00f3leo hidr\u00e1ulico \u00e9 o derivado de petr\u00f3leo, mas tamb\u00e9m existem \u00f3leos \u00e0 base de \u00e1gua e sint\u00e9ticos utilizados em sistemas hidr\u00e1ulicos. O \u00f3leo hidr\u00e1ulico, tamb\u00e9m chamado de fluido hidr\u00e1ulico, \u00e9 um componente essencial em sistemas hidr\u00e1ulicos e em alguns outros sistemas mec\u00e2nicos da atualidade.\u00a0<\/span><\/p>\n O \u00f3leo hidr\u00e1ulico \u00e9 valorizado por sua capacidade de manter uma densidade semelhante sob compress\u00e3o, permitindo que uma bomba hidr\u00e1ulica exer\u00e7a press\u00e3o atrav\u00e9s do fluido sobre um cabe\u00e7ote de cilindro ou outra superf\u00edcie r\u00edgida usada para movimentar cargas pesadas.\u00a0<\/span><\/p>\n O \u00f3leo hidr\u00e1ulico \u00e9 produzido selecionando-se uma base oleosa, como o \u00f3leo mineral, e adicionando-se \u00e9teres, \u00e9steres, glicol e outros aditivos para criar a mistura final com viscosidade e ponto de fulgor espec\u00edficos.\u00a0<\/span><\/p>\n Os sistemas hidr\u00e1ulicos necessitam de \u00f3leo hidr\u00e1ulico porque este l\u00edquido n\u00e3o pode ser comprimido tanto quanto outros, proporcionando excelente lubrifica\u00e7\u00e3o aos componentes mec\u00e2nicos. Sem um fluido hidr\u00e1ulico eficaz, um sistema hidr\u00e1ulico n\u00e3o conseguiria transferir press\u00e3o e for\u00e7a por todo o sistema. Utilizar um sistema hidr\u00e1ulico sem um fluido hidr\u00e1ulico de alta qualidade \u00e9 perigoso, pois esses sistemas frequentemente empregam milhares de quilos de press\u00e3o e podem falhar de forma perigosa se o fluido for excessivamente comprimido.\u00a0<\/span><\/p>\n Along with serving as a pressurized liquid for hydraulic systems, hydraulic fluid also functions as a coolant and a lubricant. It’s common for mechanical systems to rely on hydraulic fluid to capture and transfer heat. When paired with a radiator hydraulic fluid can be used to remove heat from a system.\u00a0<\/span><\/p>\n <\/p>\n O \u00f3leo hidr\u00e1ulico tamb\u00e9m funciona como um lubrificante importante em sistemas hidr\u00e1ulicos. Um cilindro hidr\u00e1ulico pode se mover suavemente durante o uso porque a maioria dos \u00f3leos hidr\u00e1ulicos lubrifica os pontos de atrito do sistema. A formula\u00e7\u00e3o correta do \u00f3leo permite um movimento suave do cilindro e reduz o desgaste mec\u00e2nico ao longo do tempo.\u00a0<\/span><\/p>\n Existem muitos tipos diferentes de \u00f3leos hidr\u00e1ulicos em uso atualmente, e cada fluido \u00e9 mais adequado para aplica\u00e7\u00f5es espec\u00edficas. Embora uma solu\u00e7\u00e3o flex\u00edvel \u00e0 base de petr\u00f3leo funcione bem na maioria das aplica\u00e7\u00f5es, conhecer os pontos fortes e as limita\u00e7\u00f5es de cada tipo de fluido pode ajudar a garantir o uso do fluido mais adequado para sua aplica\u00e7\u00e3o.\u00a0<\/span><\/p>\n <\/p>\n \u00c0 base de petr\u00f3leo<\/b><\/p>\n Os \u00f3leos hidr\u00e1ulicos \u00e0 base de petr\u00f3leo s\u00e3o os mais comuns e utilizados em uma ampla gama de sistemas hidr\u00e1ulicos atualmente. Os fluidos hidr\u00e1ulicos modernos \u00e0 base de petr\u00f3leo s\u00e3o compostos por uma mistura de hidrocarbonetos e aditivos projetados para prolongar a vida \u00fatil do \u00f3leo. Um fluido \u00e0 base de petr\u00f3leo serve como um excelente lubrificante e \u00e9 uma op\u00e7\u00e3o acess\u00edvel, sendo ideal para sistemas que requerem um grande volume de \u00f3leo.\u00a0<\/span><\/p>\n <\/p>\n Petroleum-based hydraulic fluids are more highly combustible and can be risky to use in some high-temperature situations. This is why it’s essential to choose the recommended hydraulic fluid for your system.\u00a0<\/span><\/p>\n <\/p>\n Sint\u00e9tico<\/b><\/p>\n O \u00f3leo hidr\u00e1ulico sint\u00e9tico est\u00e1 se tornando cada vez mais popular em sistemas hidr\u00e1ulicos atualmente, \u00e0 medida que os compostos sint\u00e9ticos melhoram. Esse tipo de fluido geralmente \u00e9 mais caro, mas leva mais tempo para se degradar e pode suportar temperaturas mais extremas sem falhar. <\/span><\/p>\n O \u00f3leo sint\u00e9tico tamb\u00e9m tende a ter uma viscosidade maior do que o \u00f3leo derivado do petr\u00f3leo, o que o torna adequado para temperaturas de opera\u00e7\u00e3o mais elevadas, pois o \u00f3leo se torna menos viscoso \u00e0 medida que sua temperatura aumenta.\u00a0<\/span><\/p>\n <\/p>\n \u00c0 base de \u00e1gua<\/b><\/p>\n A water-based hydraulic fluid is sometimes relied upon in systems where fires are a concern. A mixture such as water and glycol can be used in some hydraulic systems, but it’s essential to verify that all the components of the system are compatible with the liquid. Water-based mixtures are more likely to cause corrosion and may only be used in select applications.\u00a0<\/span><\/p>\n Every type of hydraulic oil must be replaced on a regular basis to combat the buildup of contaminants, the loss of additives, and the change in viscosity and other properties. When hydraulic fluid is new it’s mixed to a specific viscosity for optimal system performance. Over time as the fluid is exposed to incredible pressure and temperature levels the oil degrades.<\/span><\/p>\n <\/p>\n The oil oxidizes, internal system components corrode shedding contaminants into the fluid, and included additives become depleted, leaving you with an oil that doesn’t function as intended. As hydraulic oil ages, it becomes full of sludge, it can become more compressible than it once was and it can eventually damage your system if it isn’t replaced.\u00a0<\/span><\/p>\n <\/p>\n While there isn’t a recommended replacement duration that works well for every type of hydraulic fluid, experts generally recommend swapping fluid between 2,000 and 3,000 hours of use. Technicians must track use time carefully and follow manufacturer-recommended oil change intervals to protect the integrity of the hydraulic system the fluid is being used in.\u00a0<\/span><\/p>\n There are hundreds of different hydraulic oil formulations available today, in a wide range of viscosities, oil bases, oil mixtures, and more, each affecting the hydraulic fluid price. With so many different options it can feel overwhelming trying to choose an oil for your hydraulic system. The best advice is to select a hydraulic oil that matches the manufacturer’s recommendation for your system.\u00a0<\/span><\/p>\n <\/p>\n It is best to begin by using a recommended oil, and only to make minor adjustments in the type of oil that’s used over time depending on the operating environment it’s being used in. For instance, a hydraulic system used in freezing temperatures will likely require a low-viscosity fluid.\u00a0<\/span><\/p>\n <\/p>\n If a hydraulic system is used in an environment surrounded by high-temperature components, such as near the engine of an automobile, it becomes more important to select a hydraulic fluid that’s more fire-resistant.\u00a0<\/span><\/p>\n <\/p>\n If you aren’t sure which hydraulic fluid is best for your system, rely on manufacturer specifications and only make changes based on recommendations from experts.
