Designed specifically for the complex working conditions of power plants and steel mills, these filters effectively intercept impurities in high - temperature, high - dust, and highly corrosive environments with their high - strength structures and excellent filtration performance. They ensure the stable operation of key equipment and serve as a solid foundation for efficient industrial production.
The oil filter element is mainly used for filtering oil products in the hydraulic system and is installed in the filter and oil purifier in the hydraulic system. It is used in the oil circuit of the hydraulic system to remove the worn metal powder and other mechanical impurities of each component in the hydraulic system, keep the oil circuit clean, and can extend the service life of the hydraulic system. The low-pressure series filter elements are also equipped with bypass valves. When the filter element is not replaced in time, the bypass valve can automatically open to ensure the normal operation of the system. Lifert can support the customization of oil filter elements according to the user's requirements.
Entry of Impurity - laden Fluids: Fluids carrying particulate impurities, oil stains, and chemical pollutants, such as boiler feed water in power plants and blast furnace gas in steel mills, flow into the filter chamber through the filter inlet.
Gradient Interception Filtration:
Primary Filtration Layer: The outer metal mesh and coarse - effect filter material intercept large - sized dust particles, rust, etc.;
Medium - effect Layer: The intermediate composite filter material captures medium - sized impurities and adsorbs oil stains and some chemical pollutants;
Fine Filtration Layer: The inner high - precision filter material retains micron - level particles and fine impurities, ensuring fluid cleanliness.
Clean Output: The fluid filtered through the three layers flows out from the filter outlet and enters the subsequent production process.
Intelligent Monitoring and Replacement: Built - in differential pressure sensors continuously monitor the pressure difference before and after the filter. When the difference exceeds the set threshold (e.g., 0.2MPa) or the operation time reaches the cycle, the system issues an alarm to prompt filter replacement.

How does the filter ensure stable performance in high - temperature environments?
It uses special high - temperature - resistant materials and welding processes. After undergoing an 800℃ high - temperature aging test, its structural strength and filtration performance remain unaffected. It is also equipped with a heat dissipation design to prevent filter overheating and failure.
Do I need professional tools to replace the filter?
No professional tools are required. The quick - release buckle design allows operators to complete the replacement according to the instructions, reducing maintenance difficulty and time costs.
Can it be adapted to equipment from different brands in power plants and steel mills?
Customized production is supported. Filter specifications and filtration solutions can be provided according to equipment models, fluid parameters, installation space, and other requirements.
Specialized filters for power plants and steel mills are key elements in ensuring the safe and efficient production of the energy and heavy industry sectors, thanks to their industrial - grade performance, intelligent design, and wide applicability. Whether it is to cope with complex working conditions of high temperature and high pollution or to meet environmental protection requirements for energy conservation and emission reduction, long - term effective filtration can be achieved through precise selection and intelligent operation and maintenance. In the future, with the upgrading of industrial intelligence, filters will continue to integrate new materials and IoT technologies, providing more reliable technical support for the high - quality development of the energy industry.
