I. Product Overview
The STAUFF brand oil filters are produced by the German company STAUFF, which has rich experience in the field of filtration technology and offers products with superior performance. These oil filters are made of high-quality glass fiber filter materials, with a variety of filtration precisions available, ranging from 1μm, 3μm, 6μm, 12μm to 25μm. They feature a robust structure, with end caps welded by laser technology, equipped with high-strength stainless steel frameworks and oil-resistant EPDM sealing rings, ensuring excellent sealing performance. They can maintain stable performance under different pressure and temperature conditions and effectively filter out solid particles and colloidal substances in hydraulic oil, lubricating oil, etc. They are widely used for filtering pressurized oil in hydraulic and lubrication systems.
II. Working Principle
When the oil enters the STAUFF oil filter, the tiny pores on the filter element act like a precise sieve, first intercepting larger solid particles. As the oil penetrates deeper, the glass fiber filter material, relying on its special fiber structure and surface properties, further captures smaller particles as well as colloidal substances, and then transmits the clean oil through the filter element into the system. Meanwhile, the filter element also has a certain ability to remove moisture and oxides, preventing the formation of acidic substances and deposits in the hydraulic system, thus protecting various components in the system from pollution damage.
III. Main Performance
High-Precision Filtration: For example, the SE - 160G05B model filter element can intercept particulate contaminants larger than or equal to 5μm, with a filtration efficiency as high as 99.5% (β≥200), effectively meeting the strict requirements of various equipment for oil cleanliness.
High Dirt-Holding Capacity: The spiral guide design creates a turbulent flow effect when the oil passes through, increasing the dirt-holding capacity by 30% and reducing the frequency of filter element replacement, thus lowering maintenance costs.
Good Pressure Resistance: For instance, the SE - 160G05B filter element can maintain its structural integrity under a working pressure of 40 bar, ensuring stable operation in a high-pressure environment and being less likely to be damaged due to pressure changes.
Excellent Compatibility: The materials used in the filter elements have good compatibility with multiple types of oil liquids, including general hydraulic oil, phosphate ester hydraulic oil, emulsion, water-glycol, etc., making them suitable for different working media.
IV. Specific Applications in Different Industries
(I) Metallurgical Industry
They are used for filtering the hydraulic systems of rolling mills and continuous casting machines as well as various lubrication equipment. During the steel rolling process, they can effectively remove metal debris, oxide scales and other impurities in the oil, ensuring the stability and reliability of the hydraulic system, preventing equipment failures caused by oil pollution, extending the service life of the equipment and improving production efficiency.
(II) Petrochemical Industry
In the refining and chemical production processes, they can be used for the separation and recovery of products and intermediate products, liquid purification, purification in the manufacturing of tapes, CDs and photographic films, as well as particle filtration for oil field injection water and natural gas. They can ensure the cleanliness of the oil in the production process, prevent wear and blockage of production equipment caused by impurities and guarantee the smooth progress of production and the improvement of product quality.
(III) Power Industry
They are indispensable for purifying the oil in the lubrication systems, speed control systems and bypass control systems of steam turbines and boilers in thermal and nuclear power plants, as well as for purifying the feed water pumps, fans and dust removal systems. They can remove impurities and moisture in the oil, prevent corrosion and wear of steam turbines and other equipment, and ensure the safe and stable operation of power generation equipment.
(IV) Automotive and Engineering Machinery Industry
In the automotive engines and engineering machinery, they are used for air filters, oil filters and fuel filters of internal combustion engines, as well as for various hydraulic oil filters, diesel filters and water filters of engineering machinery, ships and heavy-duty vehicles. They can effectively filter out impurities in the oil, reduce the wear of engines and hydraulic systems, improve the performance and reliability of the equipment and lower maintenance costs.
V. Application Case
A large steelmaking plant used STAUFF oil filters in the hydraulic system of its continuous casting machine. Previously, due to oil pollution, the hydraulic system had frequent failures, long equipment downtime and high maintenance costs. After replacing with STAUFF oil filters, their high-precision filtration performance effectively intercepted the impurities in the oil, significantly improving the cleanliness of the system. The failure rate of the hydraulic system was greatly reduced, the equipment downtime was decreased by about 40%, and the maintenance cost was reduced by around 30%. This significantly improved the production efficiency and economic benefits.
