Atlas Copco Air Compressor Oil Check Valve Maintenance and Replacement Check Period: It is recommended to conduct checks every 1-2 years or in accordance with the equipment manual (for example, after 4000-8000 hours of operation), and perform the checks simultaneously when replacing the filter and oil. Maintenance Points: Clean the valve core and valve seat to remove impurities; Check the wear of the seals and replace them promptly if they are aged; Test the elasticity of the springs. If the elasticity is insufficient, replace the entire valve. Replacement Precautions: Select original factory parts that match the model (such as Atlas Copco, Ingersoll Rand, etc. have dedicated oil check valves). Ensure that the size and pressure parameters are consistent; Pay attention to the direction during installation, and avoid installing it in the wrong direction; After replacement, start the equipment and check if the oil circuit pressure is normal and if there is any leakage.

Atlas Copco Daily Maintenance: Manual Drain Valve: Drain at least 1-2 times per day. The drainage effect is better after the machine is shut down (at this time, the system pressure is low and water is easier to be discharged). Automatic Drain Valve: Check once a week. Clean the impurities (such as oil stains, rust) in the filter or float ball to prevent blockage. Electronic Drain Valve: Regularly check if the timer settings are reasonable, clean the electromagnetic valve valve core to ensure smooth operation. When the ambient temperature is below 0℃, take measures such as insulation or heating to prevent the drainage port from freezing and getting clogged.

1900520440 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.

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.

Atlas Copco EWD330 Electronic Drain Valve Maintenance Recommendations Compatible Models: This product is only applicable to Atlas Copco EWD330 electronic drain valves. Before purchase, confirm the production batch and electromagnetic valve specifications of the drain valve to avoid model mismatch. Maintenance Timing: When the drain valve shows slow operation, abnormal drainage (such as no drainage or continuous drainage), abnormal noise from the electromagnetic valve, or air leakage, it may be necessary to repair the electromagnetic valve. At this time, this kit can be used to replace the worn parts. Installation Notes: It is recommended to operate by professionals. Before maintenance, cut off the power and gas sources, assemble in accordance with the original factory manual specifications, ensure that the components are installed properly, and avoid functional failures or safety hazards due to improper assembly.

Atlas Copco 2906048800，The accessories in the air compressor service kit are precisely matched according to the design parameters of the equipment, effectively filtering air impurities, keeping the lubricating oil clean, separating oil from the compressed air, controlling the intake volume and pressure, and preventing faults caused by component failure. The high-quality intake valve diaphragm can prevent air leakage and avoid the continuous decrease in pressure due to inability to load after disengagement; the compatible oil-gas separator can control the oil content in the exhaust to an extremely low level, avoiding pollution of the post-treatment equipment and the gas-using equipment. The original or high-quality components in the service kit use wear-resistant and corrosion-resistant materials (such as high-precision rotors, high-quality bearings, and oil seals), which can reduce the wear of core components such as the main unit, rotor, and bearing. For example, a high-quality oil filter can filter metal particles and impurities in the lubricating oil to prevent them from entering the main unit and wearing the rotor, thereby extending the lifespan of the main unit; the compatible coolant can effectively lower the exhaust temperature, avoiding the deterioration of the lubricating oil due to high temperature and reducing the failure of the cooling system. Compared with using inferior components, in the long run, it can significantly reduce the frequency and cost of maintenance.
