China Air Compressor Oil Filter Element Manufacturer, Supplier, Factory

An air compressor is a device that compresses air into high-pressure gas and stores it. Its function is to compress a large amount of gas (usually air) to a higher pressure, enabling it to be used in various industrial, manufacturing, and construction processes.

Compressors operate in many different types of environment, affecting the inlet air. Impurities, such as dust particles, are mostly invisible to the naked eye. But they can cause damage to the compressor element, reducing its efficiency or even causing failure. They can also make the lubricant age faster and disrupt its capacity to protect metal components.

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.

Basic working principle A three-phase induction motor generates a rotating magnetic field by connecting to three-phase alternating current and passing it through the stator windings. The rotor cuts the magnetic lines of force in the magnetic field, generating an induced current, which is then subjected to electromagnetic force and rotates in accordance with the magnetic field (the rotational speed is slightly lower than that of the rotating magnetic field, and there is a slip rate). The electrical energy is converted into mechanical energy to drive the compression mechanism of the air compressor (such as pistons, screws, etc.) to operate. Adaptation features

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.

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.
