China Engine oil filter Manufacturer, Supplier, Factory

The sealing rings of the Atlas Copco 0650100087 air compressor are made of nitrile rubber and fluorine rubber. They have excellent oil resistance and wear resistance; while the fluorine rubber can withstand higher temperatures and more demanding chemical environments.

Replacement and Installation Replace after shutdown and pressure relief, ensuring that both ends are securely connected without any bends or stress; recheck the sealing and vibration after installation. If on-site fabrication is required, it is recommended to use hoses and joints of the same pressure and weather resistance grade as those from our original factory, and conduct a gas tightness test.

Key Points for Bolt Installation and Maintenance of Atlas Copco Pre-tightening Torque: Appropriate torque should be applied according to the bolt's strength grade and connection requirements . Excessive torque can cause the bolt to break, while insufficient torque may result in poor sealing or loosening. Surface Treatment: The bolt surface is usually galvanized, phosphated , or oxidized . Before installation, check the surface for rust or damage. Cooperation Precision: The cooperation between the bolt and the nut or the bolt hole must comply with standards . Avoid overly loose or overly tight threads. Regular Inspection: After the air compressor has been running for a period of time, check if the bolts are loose. If rust, deformation, or fracture is found, replace the bolts of the same specification and strength in a timely manner.

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.

Atlas Copco Gear Maintenance Tips Regular Inspection: Observe the condition of the gear tooth surface, measure the tooth clearance, and replace them immediately if any abnormalities are found. Lubrication Management: Use dedicated gear oil (or air compressor-specific oil), replace it regularly, and keep the oil level normal to avoid oil contamination. Installation Calibration: Ensure that the parallelism and perpendicularity of the gear shaft meet the requirements, and avoid uneven load operation. Load Control: Prevent the air compressor from operating under long-term overloading conditions, and reduce the fatigue damage to the gears. The design and maintenance of air compressor gears are crucial for the overall performance of the machine. High-precision gear combinations with a good lubrication system can significantly reduce operating noise, extend service life, and ensure the efficient and stable operation of the air compressor.

Replacement and Maintenance: Gaskets are wear-prone parts. They should be checked and replaced promptly during regular maintenance of the air compressor or when leakage occurs. During the replacement process, ensure the installation surface is clean to avoid poor sealing due to impurities. Also, follow the specifications in the equipment manual for proper operation to ensure a proper installation.
