Henan Xinxiang Lifelte Filter Co., Ltd. was established in 2005, is a leading industrial filtration equipment R & D and manufacturer. The company focuses on the innovation of hydraulic system, lubricating oil purification and environmental filtration technology, and its products are widely used in construction machinery, mining equipment, industrial manufacturing and other fields. Among them, WU and XU series oil absorption filters as the company's core products, with efficient filtration performance and reliable stability, has become the benchmark in the industry. This paper will deeply analyze the technical characteristics and application value of these two products. WU and XU series oil absorption filters are modular design concept, for different working conditions to achieve accurate adaptation: WU series: high-precision filtration, suitable for complex hydraulic system Core material: the use of multi-layer composite fiber filter material, filtration accuracy of up to 3-5μm, effective interception of small particles in the oil impurities.
Structure features: Built-in bypass valve design, when the filter block can automatically open the bypass channel to avoid abnormal system pressure. Application scenario: high precision CNC machine tools, injection molding machinery, precision instrument hydraulic system. XU series: High strength corrosion resistance, suitable for extreme working conditions Material upgrade: stainless steel sintered mesh and corrosion resistant coating, withstand high temperature (120℃) and acid and alkali corrosion environment. Pressure optimization: The gradual aperture structure design is used to filter impurities from large particles to micron level step by step, reducing the pressure loss of the system. Application scenarios: high-intensity operation scenarios such as mining machinery, Marine engineering equipment, and heavy engineering machinery. Technical breakthrough: Triple advantages to build filtration efficiency barrier efficient interception and low resistance balance WU series through nanofiber lamination technology, to achieve 99.9% impurity filtration efficiency, while optimizing the fluid channel design, the resistance loss is controlled within 0.2MPa, to ensure that the hydraulic system power transmission without attenuation. The XU series reduces the turbulent area by 30% through dynamic flow field simulation and extends the service life of the filter element to 1.5 times that of conventional products. Intelligent Monitoring and Maintenance Early warning Both products are equipped with differential pressure sensor and electronic monitoring module, real-time feedback filter blockage degree. When the pressure difference exceeds the set threshold, the system automatically triggers the alarm and prompts the replacement cycle to reduce the cost of manual inspection. Both environmental protection and economy Liffert's original "regenerative filter technology" enables some types of filters to recover 80% filtration efficiency through cleaning, reducing the frequency of replacement. In addition, the products comply with ISO 4406 cleanliness standards, reducing equipment wear and tear caused by oil pollution, and indirectly improving customer operations. Application Scenario: Cross-industry Solution Example Steel Manufacturing: Mill hydraulic system optimization A steel mill applied the WU-08 model to the mill hydraulic station, resulting in a 42% reduction in equipment failure rate and 25% reduction in maintenance costs. Mining: Extreme environment reliability verification In Inner Mongolia open-pit coal mine, XU-15 series filters withstand the temperature difference test of -20℃ to 60℃, continuous operation of 6000 hours without fault, the customer's "zero failure" evaluation. Wind power operation and maintenance: Long-term protection of the gearbox By integrating the WU series filter, the oil cleanliness of the wind turbine gearbox is stabilized at NAS level 6, extending the bearing life to 2.3 times the original design. Market competitiveness: Innovation-driven industry As of 2024, the domestic market share of Lifeldt oil suction filters has reached 18%, and WU and XU series have been exported to Europe, Southeast Asia and other regions. Its competitiveness stems from: technology iteration speed: 2-3 upgraded models are launched annually to respond to the needs of emerging industries. Cost-benefit ratio: In similar products, the comprehensive use cost is reduced by 15%-20%. Service network: 32 after-sales service centers nationwide, 48 hours response mechanism. With the development of industrial equipment in the direction of high precision and high durability, WU and XU series oil absorption filters focus on technological innovation and scene adaptation to provide "blood level purification" solutions for hydraulic systems. Henan Xinxiang Lifelte Filter Co., Ltd. is reshaping the value standard of the industrial filtration industry through continuous research and development and global layout.
