The air compressor oil filter is a key component of the lubrication system of an air compressor. It is mainly used to filter out impurities, particles and contaminants from the lubricating oil, ensuring that the oil entering the compressor meets the cleanliness standards, thereby protecting the internal components of the compressor (such as bearings, gears, rotors, etc.) from wear and damage, and extending the service life of the equipment. Working principle Physical interception: Through the microporous structure of the filter paper or filter element, particles larger than the pore diameter are mechanically filtered out. Adsorption effect: Some filter element materials can adsorb colloids and moisture, thereby enhancing the filtering effect.

The air compressor oil filter is a key component of the lubrication system of an air compressor. It is mainly used to filter impurities, particles and contaminants in the lubricating oil, ensuring that the lubricating oil entering the compressor meets the cleanliness standards, thereby protecting the internal components of the compressor (such as bearings, gears, rotors, etc.) from wear and damage, and extending the service life of the equipment. Core functions Impurity filtration Intercept solid particles such as metal debris, dust, and carbon deposits, preventing them from circulating into the working components of the compressor. System protection Reduce friction and wear, lower the risk of faults caused by contaminants, and improve the reliability of the compressor. Oil life extension Remove oxidation products and moisture, delay the aging and deterioration of the lubricating oil, and reduce the frequency of oil replacement.

1614727399 Large industrial screw machines may require replacement every 2,000 - 4,000 hours (in conjunction with oil quality testing); Miniature compressors (such as those for laboratories) may need to be replaced every 500 - 1,000 hours. It is essential to follow the manual and avoid equipment damage due to mismatched cycles.

Maintenance and Care Regularly replace filters: air filter, oil filter, oil-gas separator. Prevent impurities from entering the system. Check the lubricating oil: oil level, oil quality (oxidation, emulsification). Replace the oil according to the manufacturer's recommended schedule. Clean the cooling system: For air-cooled models, clean the radiator regularly; for water-cooled models, check the water quality and temperature. Tighten bolts: Prevent vibration from causing bolts to loosen, which may lead to safety hazards. Monitor operating parameters: Regularly record exhaust temperature, pressure, current, etc. Address any abnormalities promptly.

Key structural design Air intake: Gradually expanding or tangential design, reduces flow velocity and separates large particle impurities. Filter element installation: Vertical or horizontal installation, facilitating replacement and maintenance. Drainage structure: Gravity drainage port or automatic drainage valve, prevents condensate water from soaking the filter element. Sealing design: Uses nitrile rubber or fluorine rubber sealing rings, with compression ratio of 15% to 25%. Quick disassembly structure: Snap-fit or bolt connection, simplifies maintenance procedures.

I. Working Principle The safety valve is designed based on the principle of force balance. It mainly consists of a valve seat, a valve core, a spring, and a regulating mechanism. When the system pressure exceeds the spring's preload force, the valve core is pushed up, and the medium (compressed air) is discharged; when the pressure drops to the return seat pressure, the spring pushes the valve core back to its original position, closing the valve. Key parameters: Opening pressure (set pressure): The pressure at which the valve begins to open, usually 1.05 to 1.1 times the working pressure. Emission pressure: The pressure when the valve reaches its maximum opening height, generally ≤ 1.1 times the opening pressure. Return seat pressure: The pressure when the valve is closed, usually 10% to 15% lower than the opening pressure. Sealing pressure: The maximum pressure at which the valve maintains sealing, generally 90% of the opening pressure.
