China air compressor atlas copco spare part Manufacturer, Supplier, Factory

Atlas Copco 2903775400=1625775400 Notes for Attention Choosing the original factory oil filter (such as the products corresponding to these two numbers) can ensure that the filtration efficiency, size accuracy and equipment are fully matched, avoiding the risk of host wear caused by the failure of inferior filter elements. If there is a replacement relationship between the numbers, when replacing, you can directly use the new number parts, and their performance and compatibility are the same as the old numbers.

Atlas Copco 1901067022,The function of the oil suction valve of Atlas Copco air compressors: The oil suction valve is a key component of the lubrication system of air compressors. Its core function is to ensure the smooth supply of lubricating oil and maintain the stability of the system. By controlling the intake of lubricating oil, through opening or closing actions, it regulates the flow of lubricating oil entering the suction pipeline from the oil tank, ensuring that the friction parts such as the rotor and bearings of the air compressor receive sufficient lubrication. Preventing oil backflow, when the air compressor is shut down or unloaded, the oil suction valve closes, preventing the high-pressure lubricating oil in the oil tank from flowing back through the suction pipeline to the oil tank, avoiding waste of oil and system contamination. Maintaining system pressure, in coordination with pressure maintaining valves and other components, maintaining the stable pressure in the oil and gas tank, providing continuous pressure support for the lubrication system, ensuring that the lubricating oil can be smoothly transported to all lubrication points. Filtering impurities to protect equipment, some oil suction valves are equipped with filters or used in combination with suction filters to filter metal particles, dust impurities in the lubricating oil, preventing them from entering the air compressor main unit, reducing component wear.

Atlas Copco 2907012200，Load the solenoid valve, which is usually a two-position three-way normally closed valve. When powered on, it allows compressed air to enter the cylinder pipe of the intake valve from the oil-gas tank, opening the intake port; when powered off, it cuts off the air path and discharges the air in the cylinder, closing the intake port. Release the solenoid valve, which is mostly a two-position two-way normally open valve. When the air compressor is unloaded or shut down, it is powered off, releasing the gas in the oil-gas tank to the intake filter to ensure that the system pressure drops to the safe range. Pressure relief and start-up protection: In small air compressors, the solenoid valve connects the cylinder outlet to the outside when the machine is shut down to release residual pressure and prevent overload due to the motor starting under load; when starting, it closes the pressure relief channel to allow compressed air to be normally filled into the air tank.

The solenoid valve of the air compressor is a key component for controlling the flow direction, on-off and system protection of compressed air. It is mainly divided into two types: loading solenoid valves and venting solenoid valves.

Atlas Copco Maintenance and Replacement: Regularly inspect the wear, deformation or aging of the special-shaped rings (such as whether the rubber rings have hardened, or if the metal rings have cracks). Replace them immediately if any abnormalities are found. When replacing, it is necessary to use the original or the same specification special-shaped rings. Standard rings cannot be used as substitutes (even if the sizes are close, shape mismatch may still cause functional failure). During the disassembly and installation process, avoid hitting the weak parts of the special-shaped rings (such as thin walls, sharp corners), to prevent deformation and damage. Although the special-shaped rings of the air compressor are not universal, they play an irreplaceable role in special structural parts. Their design and manufacturing need to strictly match the specific requirements of the equipment, and special attention should be paid to precision and directionality during installation and maintenance to ensure the coordinated operation of all complex components of the air compressor.
