Maintenance and Fault Handling of the Oil Temperature Electronic Elektronikon Control Module of Atlas Copco Air Compressors If there are abnormal oil temperature readings, the heating/cooling system does not respond, or the oil temperature protection is triggered frequently, it may be related to this control module. Maintenance suggestions: First, check whether the oil temperature sensor and connection lines are normal. Eliminate front-end signal faults; If the module itself is faulty, it is recommended to replace the original factory parts to ensure control performance. After replacement, calibration of parameters through special tools is required to make it match the model; Regularly check the module status through the self-check function of the Elektronikon system to promptly detect potential problems.

Replacement and precautions for the oil filter housing of Atlas Copco screw-type air compressors Part matching: It is necessary to use the original Atlas Copco housing module to ensure complete matching with the model and filter cartridge model (for example, the housing specifications of different power models of the GA series are different). Installation guidelines: Clean the internal oil stains and impurities of the housing during replacement, and check if the sealing surface is flat. The new housing needs to be properly coated with sealant (if necessary) or installed with new O-rings to avoid leakage. Tighten the filter cartridge with the specified torque to prevent over-tightening from damaging the housing threads or under-tightening causing leakage. Regular inspection: During each oil filter cartridge replacement, simultaneously check for any cracks or deformations in the housing, whether the sealing parts are intact, and ensure the reliable operation of the oil circuit system.

Selection and precautions for coupling accessories of Atlas Copco compressors Model matching: The original factory accessories should be selected based on the compressor model (such as GA, G series), power, speed, pipe diameter, and pressure level to ensure that the dimensions, strength, and compensation are compatible. Original factory advantages: The original factory couplings of Atlas Copco have been tested specifically and have a high matching degree with the equipment, which can avoid vibration, leakage or safety hazards caused by size mismatch. Installation guidance: When replacing, refer to the equipment manual. If necessary, operate by professional technicians. Pay special attention to the alignment calibration (for transmission couplings) and pre-tightening force control (for pipe couplings).

Atlas Copco Air Compressor Lubricants (also known as air compressor oils) precautions For screw-type air compressors, only the dedicated screw oil (which cannot be used interchangeably with piston oil) should be used. Although oil-free air compressors do not come into contact with compressed air, the bearings and other parts still require lubrication (using dedicated lubricating grease). It is recommended to choose the original factory lubricants (Atlas Copco) recommended by the equipment manufacturer to ensure compatibility and performance matching. Correct selection and maintenance of lubricants can significantly reduce the failure rate of air compressors, extend equipment lifespan, and at the same time reduce energy consumption and maintenance costs.

Attention for the suction control valve of Atlas Copco air compressors: After replacing or repairing the suction control valve, it is necessary to recalibrate the pressure setting value to ensure it matches the system requirements. Avoid using non-original factory parts to prevent abnormal operation of the compressor due to size deviations or material issues.

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.
