In modern industrial production, the cleanliness of hydraulic system and lubrication system directly affects the operating efficiency and service life of equipment. HYDAC, as a world-renowned brand of oil filtration equipment, its products are known for high performance, but high prices and maintenance costs make some enterprises prohibitive. Henan Xinxiang Lifelte Filter Co., Ltd. relies on years of technology accumulation, independent research and development of alternative HYDAC oil filter products, not only to achieve a comprehensive benchmark of technical parameters, but also in cost-effective, localized services and other aspects of the unique advantages.
This paper will analyze this innovative product from multiple dimensions such as technical characteristics, operation guidelines, maintenance, application scenarios and market prospects. 1. ** Multi-layer composite filtration system, to achieve high precision filtration ** Liefert filter adopts "coarse filter + fine filter + dehydration" three-stage filtration technology, the core components include: ** Initial effect filter layer ** : stainless steel mesh filter element, block ≥100μm of large particles of impurities, protect the subsequent filter element. ** High precision filter layer ** : Imported glass fiber filter element (filtration accuracy up to 3μm), effectively remove small metal particles, wear residue and pollutants in the oil. ** Dehydration separation layer ** : Vacuum separation technology removes free and emulsified water from oil to ensure oil cleanliness to NAS Level 6 (equivalent to ISO 4406 15/12/9). 2. ** Intelligent control system, realize automatic operation ** **PLC programmable control ** : Support timing start, automatic pressure adjustment, fault alarm and other functions, reduce manual intervention. ** Real-time monitoring module ** : real-time monitoring of oil temperature, pressure, filter life and other parameters through the sensor, data can be remotely transmitted to the central control system for preventive maintenance. ** One-click cleaning function ** : Some models are equipped with automatic backwash system to extend the service life of the filter element and reduce maintenance costs. 3. ** Energy-saving design and environmental protection materials ** ** High efficiency motor and energy-saving pump set ** : compared with traditional oil filter, energy consumption is reduced by 20%, in line with GB/T 30254-2013 "Hydraulic Transmission system energy-saving technical Guidelines" standard. ** Environmental protection sealing material ** : fluorine rubber sealing ring, oil temperature resistance of 120℃, prevent leakage risk, in line with the EU ROHS environmental protection directive. 4. ** Modular design, strong adaptability ** ** a variety of specifications optional ** : covering flow 5-500L/min, pressure 0.6-2.5MPa of multiple models, can be adapted to construction machinery, mining equipment, power system and other different scenarios. ** Customized service ** : Support non-standard design, can be customized according to customer special needs (such as explosion-proof, corrosion resistance, etc.) oil filter system. 1. ** Installation preparations ** ** Environmental requirements ** : Install the equipment in a dry and ventilated place, avoid high temperature (> 50 ° C) or humid environment, the foundation floor must be level, and the load capacity must be at least 1.2 times of the device weight. ** Pipeline connection ** : 1. The oil inlet connection needs to be equipped with a stop valve, which is easy to cut off the oil circuit during maintenance; 2. It is recommended to install a pressure gauge at the oil outlet to monitor the system pressure in real time; 3. Ensure that all joints are sealed reliably to avoid oil leakage. 2. ** Before starting ** ** Electrical check ** : Ensure that the power voltage is consistent with the device nameplate and the ground cable is securely connected. ** Oil check ** : The oil level of the tank should be higher than the lowest liquid level line, and the oil temperature should be in the range of 15-60℃. ** Filter element inspection ** : Before the first use, make sure that the filter element is installed in place and is not loose or damaged. 3. ** Operation process ** ** Start ** : Press the "Start" button, and the device will enter the self-test program (about 30 seconds), and run automatically after confirming that there is no alarm. ** Parameter setting ** : Set parameters such as running time, pressure threshold and backwash cycle through the touch screen (see equipment operation manual for details). ** Stop ** : press the "Stop" button, turn off the power when the equipment is completely stopped, and close the inlet and outlet oil valve. 4. ** Emergency Shutdown treatment ** In case of sudden failure (such as abnormal oil pressure rise, abnormal equipment noise), immediately press the "emergency stop" button, and cut off the power supply, contact technical personnel for investigation. Maintenance and troubleshooting 1. ** Daily maintenance (daily) ** Check the tank level, oil temperature and pressure gauge reading, record the operating parameters. Clean the oil on the surface of the equipment and keep the working environment clean. 2. ** Regular maintenance (weekly/monthly) ** ** filter replacement ** : According to the degree of oil pollution, it is recommended to replace the fine filter element every 500-1000 hours (if the differential pressure gauge shows ≥0.5MPa, it should be replaced immediately). ** Tank cleaning ** : monthly discharge of sediment at the bottom of the tank, if necessary, use a special cleaning agent to clean the inner wall of the tank. 3. ** Annual maintenance (annual) ** Disassemble and check the pump set, motor bearings, and fill with lubricating oil (ISO VG46 anti-wear hydraulic oil is recommended). Calibrate pressure sensors and temperature sensors to ensure accurate monitoring data. 1. ** Metallurgical industry -- Protection of blast furnace hydraulic system ** ** Application scenario ** : blast furnace hydraulic system needs to withstand high temperature (80-120℃) and high pressure (≥25MPa), and the oil is easy to oxidization and deterioration. ** Solution ** : Liffert oil filters effectively extend the service life of hydraulic oil (from 6 months to 12 months) and reduce the failure rate of equipment through high-precision filtration and dehydration modules. 2. ** Wind power industry -- gearbox lubrication system ** ** Application scenario ** : Wind turbines are exposed to the outdoors all year round, and the lubricating oil is easy to mix with sand and water. ** Solution ** : The oil filter is equipped with automatic backwashing function, combined with remote monitoring system, to achieve unattended filtration and reduce maintenance costs.
3. ** Engineering machinery -- excavator hydraulic system ** ** Application scenario ** : excavator starts/stops frequently, hydraulic oil pollution is fast, and the filter element of traditional oil filter is replaced frequently. ** Solution ** : Liffert oil filters extend filter life by 30% and reduce downtime through a multistage filtration system. Market demand According to MarketsandMarkets, the global oil filter market is expected to reach $4.5 billion in 2025, with a CAGR of 7.2%.
