Atlas Copco Air compressor LOCKNUT Main functions Anti-loosening fixation: During the operation of the air compressor, continuous vibration will occur. The locking nut, through special design (such as threaded structure, additional anti-loosening elements), can effectively prevent the connection components from loosening, ensuring the stable operation of the equipment. Sealing assistance: At the connection parts involving the air circuit and oil circuit, the locking nut combined with the sealing element (such as O-ring) can enhance the sealing effect, preventing air leakage and oil leakage. Adjustment and positioning: For some parts, the locking nut can be used to adjust the position of the components (such as pistons, bearings, etc.), and then locked to maintain accuracy.

Notes for Attention Regular inspection: The pressure relief valve should be subject to regular functional checks and calibrations to ensure it operates properly in case of abnormal pressure, preventing failure due to issues such as valve core jamming. Replacement of genuine products: When replacing the pressure relief valve, it is recommended to choose original Atlas Copco spare parts or products from authorized official channels to ensure compatibility with the equipment and safety. Professional installation: The installation process should be carried out by professional technicians to ensure reliable valve connection and sealing, and to meet the pressure specification requirements of the equipment.

Faults and Replacement Suggestions: Common Faults and Handling: Contact Erosion: Manifested as poor contactor engagement, severe overheating, or failure of the main circuit. Replace the contactor to prevent the motor from operating without phases; Winding Burnout: Usually caused by abnormal voltage or winding aging, resulting in the contactor unable to engage. Check the winding voltage and replace the original part; Stuck and Strange Noise: Caused by dirty iron core or failed spring. May lead to contact adhesion. Replace immediately to prevent the equipment from losing control. When replacing, please note: Power off and confirm that the main circuit voltage has been disconnected. When connecting, distinguish between the main contact (high-power circuit) and the auxiliary contact (control circuit). Secure the connection terminals to prevent loosening and overheating.

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.

Replacement and selection suggestions for flat washers of Atlas Copco air compressors When replacing, it is necessary to strictly match the original specifications to avoid sealing failure or connection loosening due to size mismatch. For high-pressure, high-temperature or areas in contact with compressor oil, it is recommended to use original factory metal flat washers to ensure that the material is oil-resistant and pressure-resistant. If it is a critical sealing part (such as the end cover of the oil-gas separator), check whether the surface of the washer is flat, without scratches or deformation. If necessary, replace the new part to ensure the seal. For specific models or part numbers, you can refer to the parts manual of the air compressor (usually identified by a numerical code, such as 0650 series, 1622 series), or consult the Atlas Copco after-sales service for the equipment model to obtain precisely matched parts.

Recommendation for Selecting Special Pressure Sensors for Atlas Copco Screw Air Compressors It is essential to use original Atlas Copco pressure sensor spare parts. These parts have undergone rigorous precision calibration and environmental adaptability tests, ensuring compatibility with the compressor control system and measurement accuracy. Third-party parts may have issues such as insufficient precision, signal mismatch, or short lifespan, which can easily lead to control failure or equipment malfunctions, thereby affecting the safe and stable operation of the air compressor.
