introduction
The RFB series self-sealing return oil filter is a precision filtration device specifically designed for hydraulic systems. It primarily serves to filter out contaminants such as metal particles generated by component wear and rubber impurities from worn seals, ensuring that the oil returning to the tank remains clean. This, in turn, protects the hydraulic system from contamination, enhancing its stability and reliability.
Product Features
- Compact Structure: Typically installed directly on the side, bottom, or top of the oil tank, it simplifies system piping and contributes to a more compact system layout.
- Easy Installation: The inlet port features threaded and flanged connections for convenient connection to the return oil pipeline, making the installation process simple and quick.
- Comprehensive Protection Mechanism: Some models are equipped with bypass valves and sensors. When the filter element becomes clogged or insufficient inlet pressure occurs due to low system fluid temperature, the bypass valve automatically opens to protect the system, while the sensor sends a signal indicating filter element replacement is necessary.
- Extended Filter Element Life: Return oil holes on the filter head's side and upper cover allow for a small amount of oil from the system to be filtered back into the tank or for topping up the tank with oil. They also facilitate draining contaminated oil from the filter, thereby extending the filter element's lifespan.
- Reduced Bubbles and Air Re-entry: The diffuser located at the bottom of the return oil cylinder ensures a smooth flow of oil into the tank, minimizing bubble formation and agitating settled contaminants, thus reducing air re-entry.
- High Filtration Accuracy: Filter elements often utilize new chemical fiber materials like glass fiber, offering advantages like high filtration accuracy, large oil flow capacity, low initial pressure loss, and substantial dirt-holding capacity.
application area
The RFB series self-sealing return oil filter finds extensive application in various hydraulic systems, particularly in scenarios requiring high oil cleanliness standards, such as in metallurgy, petrochemicals, textiles, mechanical processing, mining, construction machinery, and other industries. It effectively removes impurities and contaminants from the oil, safeguarding hydraulic system components from wear and damage, extending the system's lifespan, and enhancing its stability and reliability. Additionally, this filter is compatible with multiple working media, offering a broad range of applicability.
Customized filters of different specifications and models are available upon user's request.
