How does a bypass filter work on an excavator?
A bypass filter is a secondary oil filtering system that is added to an excavator’s oil filtration system. The bypass filter works by providing an additional filtering process to remove small particles and contaminants that could not be removed by the primary oil filter. The bypass filter is designed to filter out particles as small as 1 micron, which is significantly smaller than the primary filter.
When the engine runs, oil flows through the primary oil filter and then through the bypass filter. The bypass filter is designed with a unique filter media that has a large surface area and small holes, which allows it to filter out tiny particles that could clog the engine components. The bypass filter also has a high flow rate, which allows it to handle the heavy flow of oil that is required by an excavator.
The bypass filter works by utilizing the principle of centrifugal force to remove contaminants from the oil. The oil is forced through a spiral channel, where it is subjected to centrifugal force. This force separates the particles of different sizes, and the heavier particles are separated from the oil and collected in a separator or housing. The clean oil then flows back into the engine, while the contaminants are disposed of in the separator.
The bypass filter works continuously to separate and remove contaminants from the oil, ensuring that the oil stays clean and free of particles that could cause damage to the engine components. With a bypass filter added to an excavator’s oil filtration system, the oil is kept free of contaminants, which reduces wear and tear on the engine and extends the lifespan of the excavator.
En conclusion, un filtre de dérivation est essentiel pour entretenir le système de filtration d'huile d'une excavatrice et garantir la circulation d'une huile propre dans les composants du moteur. En utilisant le principe de la force centrifuge, le filtre de dérivation est capable d'éliminer les particules aussi petites que 1 micron, ce qui est nettement plus petit que le filtre primaire. Cela aide à réduire l'usure des composants du moteur, prolongeant ainsi la durée de vie de la pelle.
