Maintenance and Replacement Precautions for Atlas Copco Air Compressor Oil Check Valve Kit Regularly inspect the sealing performance and operational flexibility of the check valve to prevent failure of the check valve or increased resistance in the oil circuit due to valve core jamming or wear of the sealing components. When replacing, use the original factory kit to ensure compatibility with the oil circuit parameters of the model , to avoid affecting the lubrication effect due to incompatible specifications. Before installation, clean the oil circuit interface to remove impurities; after installation, check the oil circuit pressure through trial operation to confirm there is no leakage before putting it into use. It is recommended to replace with lubricating oil, oil filters, etc. at the same time to ensure the cleanliness and performance consistency of the entire oil circuit system.

Maintenance and replacement precautions for LDI drain valves of Atlas Copco air compressors Regularly check the working condition of the drain valve, observe whether the drainage is smooth, and avoid failure of drainage due to blockage by impurities (manual drainage can be performed periodically for auxiliary cleaning). If there is continuous leakage or inability to drain, the sealing parts or the entire valve body should be replaced in time to avoid affecting the quality of compressed air. When replacing, select the compatible model to ensure that the pressure grade, interface size, and equipment are matched; before installation, the system pressure should be emptied to prevent fluid ejection. Before long-term shutdown, it is recommended to manually discharge the residual water in the system to protect the drain valve and pipeline from corrosion.

The metal control panel instrument controller switch assembly of the Atlas Copco mobile air compressor, usage and maintenance precautions: Regularly clean the surface of the panel to prevent dust accumulation from affecting observation and operation; check the flexibility of the switch buttons to prevent sticking. Fasten the fixing screws of the panel to prevent components from loosening or poor contact due to equipment vibration. When replacing components, select original factory parts to ensure that they match the electrical parameters and installation dimensions of the model (such as XAS, XR series of mobile compressors). In humid environments, pay attention to protection to prevent moisture from seeping into the interior and causing circuit short circuits.

Maintenance and servicing tips for the tubular coolers of Atlas Copco compressors: Regular cleaning: Depending on the operating environment, clean the inside and outside of the cooling tubes of the tubes and the sealing surfaces of the caps (using chemical cleaning or mechanical flushing) to prevent a decline in heat exchange efficiency. Leak detection: Check for any leaks at the pipe connections and sealing surfaces of the caps. Replace the seals or repair damaged pipes in a timely manner. Flow monitoring: Ensure that the flow and pressure of the cooling medium (water or air) are within the specified range. If insufficient, investigate pipe blockages or pump/fan failures. Anti-freezing protection： In low-temperature environments， after shutdown， drain the accumulated water in the cooling water pipes to prevent cracking due to freezing.

Maintenance and replacement precautions for the CD5-2 valve used in Atlas Copco's oil-free ZR-ZT type compressors: Regularly check the flexibility of the valve components' operation and the sealing performance to prevent control failure due to impurities blocking or valve core jamming. When replacing, use original factory parts to ensure compatibility with the specific model (such as different power ratings of the ZR/ZP series) to avoid affecting the system's pressure control accuracy due to parameter mismatch. Before installation, clean the gas path interface to prevent impurities from entering the valve body; after installation, conduct a pressure test to confirm no leakage and normal operation before putting it into operation.

Maintenance Precautions for Atlas Copco Hydraulic Water Solenoid Valve Regularly check the energized state and sealing performance of the solenoid valve to prevent control failure due to valve core jamming or coil aging. When replacing, select original factory parts to ensure compatibility with the model (there may be differences in diameter, pressure rating, and voltage parameters between different types of screw machines for hydraulic and water solenoid valves). During maintenance, first cut off the pressure source of the related pipelines and operate after the system is depressurized to avoid fluid leakage or component damage.
