PLF series Pressure line filters: The precise guardian of hydraulic systems

In the field of industrial automation and precision control, the stability and reliability of hydraulic systems are directly related to the operating efficiency and life of equipment. The PLF series pressure pipeline filter launched by Henan Xinxiang Lifelte Filter Co., Ltd. provides a full range of pollution protection for the hydraulic system with its excellent filtration performance and technical innovation, and becomes the core component of the automatic control system and servo system. The "Heart" PLF series filters are designed for high pressure lines and can be adapted to different pressure levels of the system environment. Its core function is to intercept intrusive particle impurities, metal debris generated by component wear, and pollutants generated by chemical reactions in the medium. Through the dual role of physical filtration and chemisorption, the filter can effectively purify the oil and prevent contaminants from causing wear or sticking on high-precision control components (such as servo valves, proportional valves) and actuator components (such as hydraulic cylinders, motors). The data shows that after using PLF filter, the system failure rate can be reduced by 30%, the service life of the components can be extended by more than 25%, and the operation stability of the equipment can be significantly improved. Imported filter material, casting filter "gold standard" This series of filters adopts imported high-strength glass fiber filter material, its filtration accuracy is calibrated with absolute accuracy, up to β3, β5, β10, β20≥200 (that is, filtration efficiency n≥99.5%), far beyond the industry standard. This means that particles with a diameter of more than 3 microns are almost completely blocked, ensuring that the oil meets the requirements of ISO 4406-18/15. At the same time, the unique gradient structure design of the filter material enables the filter to have both high oil capacity and low original pressure loss: at the rated flow rate, the initial pressure drop is only 0.05MPa, effectively reducing the system energy consumption; The pollution capacity is up to 500g/L, which is twice that of ordinary filters, greatly extending the filter replacement cycle and reducing maintenance costs. The PLF series offers a variety of specifications and models, covering the pressure range of 1-40MPa and the flow range from 10L/min to 1000L/min, which can flexibly match the hydraulic system of construction machinery, metallurgical equipment, wind power system, injection molding machinery and other fields. Its compact structure design, installation size in accordance with DIN standards, compatible with the mainstream pipe interface on the market, no modification can be quickly replaced. In addition, the filter is equipped with a visual differential pressure indicator that automatically alerts when the filter element is blocked, avoiding system risks due to manual negligence. The Liffert research and development team has optimized the flow path design of the filter through fluid dynamics simulation to minimize turbulence losses as the oil passes through the filter element. The original "self-cleaning" technology uses reverse pulse air flow to regularly clean the impurities attached to the surface of the filter material, further extending the service life of the filter element. At the same time, all parts of the filter are made of corrosion-resistant materials, and through 100% air tightness testing, to ensure stable operation under extreme conditions of -20 ° C to 120 ° C. Since PLF series has been put into the market, it has served more than 2000 industrial customers around the world. In wind turbine gearbox lubrication system applications, the filter improves the oil cleanliness from NAS 9 to NAS 6, and the gear life is extended by 40%; After the filter is used in the hydraulic system of a steel mill, the annual maintenance cost is reduced by 180,000 yuan. Excellent product quality and perfect after-sales service, so that Lifelt for three consecutive years was awarded "China hydraulic industry Top ten filter brand". In the era of Industry 4.0, equipment intelligence puts forward higher requirements for the cleanliness of hydraulic systems. PLF series pressure line filter with precision filtration technology as the core, with reliability as the cornerstone, for the hydraulic system to build a solid pollution defense line. In the future, Liffert will continue to focus on filtration technology innovation to create more efficient and environmentally friendly fluid purification solutions for industrial customers around the world.
