Blood purifier guarding the hydraulic system——ZU-A QU-A WU-A XU-A return line series

In the roar of construction machinery, the hydraulic system is like a precise blood network to maintain the normal operation of the equipment. The ZU-A, QU-A, WU-A, XU-A series oil return filters created by Henan Xinxiang Lefilter Filter Co., Ltd. are like loyal "blood guards", which build an indestructible pollution defense line at each node of the oil circulation. These seemingly ordinary filtration devices are actually the core guarantee for modern industrial equipment to achieve long life and high reliable operation. Core technology to build pollution prevention system Lifeldt series oil return filter adopts multi-layer composite filtration technology to build a triple protection network of "coarse filter - fine filter - deep filter". The first layer of stainless steel mesh filter element intercepts ≥100μm of large particles of pollutants, the middle layer of glass fiber filter material can capture 10-30μm of metal debris, and the deep nanofiber material can sweep up 3-5μm of small impurities. This stepped filter structure makes the filtration efficiency up to 99.7%, effectively extending the service life of hydraulic oil by 3-5 times. The original "hydrodynamic guide tank design" greatly reduces the fluid resistance, and the pressure loss is only 0.2MPa at the 25L/min flow rate, ensuring zero power transmission loss of the hydraulic system. 

Using aero-grade sealing ring and corrosion-resistant engineering plastic shell, the product can operate stably in extreme environments ranging from -40 ° C to 120 ° C, meeting the needs of all scenarios from polar exploration to tropical construction. Modular design enables intelligent operation and maintenance According to the needs of different working conditions, Lifelter provides "standard type - high pressure type - explosion-proof type - custom type" four-level product matrix. The ZU-A series focuses on construction machinery, the WU-A series ADAPTS to wind power equipment, and QU-A and XU-A are optimized for metallurgical rolling mills and shield machinery respectively. This modular design concept enables customers to quickly build filtering solutions for their own devices like building blocks. The intelligent differential pressure sensor monitors the status of the filter element in real time. When the pressure difference exceeds 1.6MPa due to the accumulation of pollution, the red warning window automatically pops up to remind the replacement. The detachable quick-mount structure reduces maintenance time by 80%, and the filter cartridge can be replaced without professional tools, significantly reducing equipment downtime costs. Life cycle cost revolution Traditional filters need to be replaced every 2,000 hours, while Liffert products extend the replacement cycle to 8,000 hours thanks to their large contamination capacity. Taking a certain type of excavator as an example, the average annual purchase cost of filter element can be reduced by 23,000 yuan and maintenance hours can be saved by 120 hours. This two-way optimization of "low procurement cost + high efficiency" is redefining the value model of industrial filters. Products with ISO 16889 filtration accuracy certification and CE safety certification maintain zero leakage during 100,000 pulse fatigue tests. 

The use of renewable filter technology, so that waste filter recovery rate increased to 85%, for enterprises to practice green manufacturing to provide solid support. In the wave of intelligent manufacturing sweeping the world today, the Lifelte oil return filter is not only the guardian of the hydraulic system, but also the key component of the intelligent upgrade of industrial equipment. From precision machine tools to giant shield machines, new energy equipment to traditional heavy machinery, these "invisible heroes" hidden in the pipeline are interpreting the innovative power of China's filtration technology with excellent performance. When the hydraulic oil flows quietly through the pipeline, Lifeldt filters have used technology to inject sustainable power into the industrial veins.
