The main function of the precision filter AZ3E303-01D01V/W is to filter the particulate impurities left behind by the operation of the diatomaceous earth filter and alumina filter, ensuring the cleanliness of the oil and the efficient operation of the system. The following are the specific functions of the filter element:
1. Efficient filtration performance
-High filtration accuracy: The precision filter AZ3E303-01D01V/- W has a high filtration accuracy of 1 μ m, which can effectively remove small particles, metal debris, and other impurities in fire-resistant oil. This high-precision filtering performance can significantly improve the cleanliness of the oil, preventing these particles from entering key hydraulic components such as servo valves, thereby reducing the possibility of wear and failure.
-Good filtration efficiency: The filtration efficiency of the filter element is as high as 99.9%, which can ensure that impurities in the oil are effectively intercepted and keep the oil clean. This efficient filtering performance helps maintain the high quality of oil and extend the service life of hydraulic components.
2. Protect system components
-Preventing particles from entering key components: By removing particles from the oil, precision filters can effectively prevent these particles from entering key components such as servo valves, pumps, and valves. This helps to reduce the possibility of wear and failure, and improve the overall reliability and safety of the system.
-Maintaining system performance: The efficient filtration performance of precision filters can ensure the cleanliness of oil products, thereby maintaining the normal operation of the system. This is crucial for the cleanliness and performance of high-pressure fire-resistant oil in EH systems (electro-hydraulic control systems).
3. Used in conjunction with the acid removal filter element
-Forming a complete regeneration system: The precision filter element and the acid removal filter element are used in series to form a complete anti fuel regeneration system. The acid removal filter is responsible for reducing the acid value and moisture content in the oil, while the precision filter further removes particulate pollutants to ensure the overall quality of the oil reaches its optimal state.
-Improving oil quality: By working in conjunction with acid removal filters, precision filters can effectively enhance the quality of oil products. This helps to extend the service life of oil products and reduce maintenance costs of the system.
4. Installation and maintenance
-Installation position: The precision filter element is installed in a separate oil filter pipeline and arranged in series with the acid removal filter element. Each filter is equipped with a pressure gauge and a differential pressure indicator to monitor the working pressure and the status of the filter element.
-Replacement condition: When the oil pressure inside the cylinder reaches 0.3MPa, it indicates that the precision filter element may have been clogged and needs to be replaced. After 48 hours of operation of the regeneration device, if the acid value of the fire-resistant oil no longer decreases or exceeds 0.1, it should be considered to replace the acid removal filter element. After continuous use for 2-3 months, even if there are no obvious abnormalities, it is recommended to replace the acid removal filter to ensure the long-term stable operation of the system.
-Pre treatment and replacement steps: Before replacing the filter element, it is recommended to bake the new filter element in a 120 ℃ oven for 8 hours or in a 110 ℃ drying oven for 12 hours, then cool it to 20-30 ℃ in the oven before immediately placing it into the filter cartridge. When replacing, it is necessary to close the corresponding valve, open the oil filter cover, remove the old filter element, and install a new filter element.
