Atlas Copco Air Compressor Oil Check Valve Maintenance and Replacement Check Period: It is recommended to conduct checks every 1-2 years or in accordance with the equipment manual (for example, after 4000-8000 hours of operation), and perform the checks simultaneously when replacing the filter and oil. Maintenance Points: Clean the valve core and valve seat to remove impurities; Check the wear of the seals and replace them promptly if they are aged; Test the elasticity of the springs. If the elasticity is insufficient, replace the entire valve. Replacement Precautions: Select original factory parts that match the model (such as Atlas Copco, Ingersoll Rand, etc. have dedicated oil check valves). Ensure that the size and pressure parameters are consistent; Pay attention to the direction during installation, and avoid installing it in the wrong direction; After replacement, start the equipment and check if the oil circuit pressure is normal and if there is any leakage.

In the world of industrial air solutions, Atlas Copco Stationary Compressors have earned a global reputation for reliability, performance, and energy efficiency. Whether you are in manufacturing, construction, or automotive industries, having a dependable air compressor system is critical for productivity and long-term cost savings. But what makes these compressors stand out from others in the market? In this article, we'll explore their advantages, specifications, and real-world applications to help you understand why they are the preferred choice for businesses worldwide.

Maintenance and precautions for the control unit of Atlas Copco air compressors Regularly check the display screen and buttons of the control unit to ensure they are functioning properly and that the heat dissipation and ventilation are adequate, to prevent the impact of high temperatures on performance. If a fault code appears, it is recommended to refer to the equipment manual for interpretation or contact the authorized service center of Atlas Copco for handling to avoid the expansion of problems due to self-operation. Some control units support firmware upgrades, and updates can be obtained through official channels to enhance functional stability.

Common Types and Functions Shaft Sleeve: Protects the shaft journal, provides a wear-resistant surface, and facilitates maintenance and replacement; often used in conjunction with oil seals. Oil Seal / Oil Cap: Prevents the leakage of lubricating oil along the shaft, the material is usually nitrile rubber (NBR) or fluororubber (FKM), with a double lip design that can scrape off oil and prevent dust. Shaft Sleeve / Shaft Seal Kit: Includes a shaft sleeve + oil seal + related installation parts, providing a one-step solution with good compatibility.

Atlas Copco's metal oil pump component service kit replacement and maintenance recommendations for the ZR/ZL 55-90 series screw air compressors When there are abnormal oil pump noises, fluctuating supply pressure, insufficient lubricating oil flow, or oil leakage in the oil circuit, it is recommended to check the oil pump status and use this service kit for maintenance. During the replacement process, strictly follow the procedures in the equipment manual to operate and ensure the correct installation of the components (such as the gear meshing position and the assembly direction of the seals), and conduct a pressure test after the repair to confirm that the performance of the oil pump has returned to normal.

Replacement and Maintenance Precautions If you find that the return oil pipe has corrosion perforations, damaged interface threads, deformed pipes, or leaks, it must be replaced immediately; otherwise, it will cause oil loss, insufficient lubrication, and lead to wear of the main engine. When replacing, it is necessary to use the original factory metal return oil pipe to ensure that the size, interface are consistent with the original components, and avoid installation difficulties or leakage due to mismatch issues. During installation, check whether the sealing parts (gaskets, O-rings) are in good condition. If necessary, replace them simultaneously; when tightening the interface, operate according to the specified torque to prevent excessive tightness from causing thread damage or insufficient tightness that leads to leakage.
