The direct return self-sealing oil return filter is a device used for precise oil return filtration in hydraulic systems. Its primary function is to filter out contaminants such as metal particles generated by component wear and rubber impurities from seals, ensuring that the oil flowing back into the tank remains clean. Below is a detailed introduction to the direct return self-sealing oil return filter:
I. Functions and Applications
Main Functions: The direct return self-sealing oil return filter effectively removes impurities from hydraulic systems, maintaining oil cleanliness, thereby prolonging the service life of hydraulic systems and reducing the occurrence of failures.
Applications: Widely used in various hydraulic systems, including construction machinery, metallurgical equipment, marine machinery, injection molding machines, etc., it is an indispensable and crucial component of hydraulic systems.
II. Features and Advantages
Easy Installation: The direct return self-sealing oil return filter can be directly installed on the top, side, or bottom of the oil tank, simplifying system piping and making the system layout more compact.
High Filtration Accuracy: Equipped with a permanent magnet, the filter can remove ferromagnetic particles larger than 1 micron from the oil. The filter element, made of materials like glass fiber, boasts high filtration accuracy, large oil flow capacity, low initial pressure loss, and high dirt-holding capacity.
Intelligent Monitoring: Some direct return self-sealing oil return filters are equipped with transmitters, bypass valves, and other devices. When the filter element is clogged with contaminants or factors like low system oil temperature and flow pulsation cause abnormal inlet pressure, the transmitter will issue a signal, reminding users to replace the filter element or take other measures promptly.
Self-sealing Function: During filter element replacement or other maintenance operations, the filter can automatically seal the oil path, preventing oil leakage and ensuring operational safety and convenience.
III. Structure and Composition
The direct return self-sealing oil return filter primarily consists of a filter head, filter element, housing, transmitter, bypass valve, and other parts. The filter head connects the oil tank and the filter, while the filter element undertakes the primary filtration task. The housing is immersed in the oil tank, allowing oil to flow smoothly through the filter.
