Atlas Copco Operating Instructions The 40°C setting value for Atlas Copco is an optimized parameter specific to certain models or working conditions. It cannot be adjusted at will. Otherwise, it may affect the temperature control accuracy, leading to reduced equipment operation efficiency or component damage. When replacing parts, choose Atlas Copco original accessories to ensure they match the temperature control logic and interface of the equipment. Avoid system failures caused by compatibility issues. For specific model compatibility or more detailed technical parameters, it is recommended to refer to the equipment manual or contact the Atlas Copco authorized service center for confirmation.

Atlas Copco confirms the type of lubricating grease Based on the type of air compressor components and operating conditions , select the matching special lubricating grease . It is strictly prohibited to mix different types or grades of lubricating grease . Check the parameters of the lubricating grease: such as applicable temperature range, pour point , and penetration . Atlas Copco cleans the components to be lubricated Stop the machine and ensure the components are completely cooled. Use oil-free cotton cloth or dedicated cleaning agents to wipe the old lubricating grease, oil stains, dust, and metal debris on the surface of the components, especially the key areas such as the bearing seat and the meshing surface of the gears, which need thorough cleaning .

Common Issues and Maintenance of Atlas Copco Air Compressor Pressure Sensors Common issues with pressure sensors include measurement drift , signal interruptio, interface leakage, etc. Maintenance suggestions: Regularly check the sealing of the sensor installation to avoid pressure leakage or measurement errors due to looseness; Keep the sensor interface clean to prevent oil contamination and impurities from blocking and affecting the measurement; When there is abnormal pressure display, frequent start-stop of the unit, or incorrect pressure protection operation, it is necessary to check if the sensor is faulty. It is recommended to replace the original sensor to ensure performance matching. When replacing, pay attention to keeping the calibration parameters consistent with the original model.

The control unit of Atlas Copco's injection-type screw compressors is designed with intelligence, which not only simplifies operation management but also significantly improves the operating efficiency and reliability of the equipment. It is a key guarantee for achieving the "efficient, energy-saving, and safe" operation of the compressors. When choosing, it is necessary to match the corresponding specification of the control unit according to the compressor model and actual working conditions.

Working principle： Expansion and contraction driven: The constant temperature valve mainly operates based on the principle of thermal expansion and contraction. Special expansion temperature-sensitive paraffin wax and other components are usually used as the temperature sensing elements. When the oil temperature rises to the melting point of the paraffin wax, the wax expands significantly, generating a large force that pushes the push rod, causing the valve core to move and opening the valve; when the oil temperature drops, the paraffin wax contracts due to the cold, and under the spring rebound effect, the valve core resets, closing or reducing the valve opening. Oil passage control: The expansion and contraction of the valve core is used to adjust the changes in the oil passage between the valve body and the housing, thereby controlling the proportion of lubricating oil entering the oil cooler. When the oil temperature is lower than the set value, the valve closes or the opening degree decreases, and the lubricating oil directly returns from the oil-gas tank to the main unit, achieving rapid heating; when the oil temperature is higher than the set value, the valve opens, allowing the lubricating oil to enter the cooler for cooling, and the cooled lubricating oil returns to the main unit, thereby ensuring that the rotor temperature remains within the set range.
