China atlas copco air compressors Manufacturer, Supplier, Factory

Choosing the Atlas Copco WUX service package can help users reduce equipment downtime, increase production efficiency, and prevent equipment damage caused by improper maintenance. It is an important service solution for ensuring the continuous and reliable operation of Atlas Copco equipment.

Atlas Copco Maintenance and Replacement: Regularly inspect the wear, deformation or aging of the special-shaped rings (such as whether the rubber rings have hardened, or if the metal rings have cracks). Replace them immediately if any abnormalities are found. When replacing, it is necessary to use the original or the same specification special-shaped rings. Standard rings cannot be used as substitutes (even if the sizes are close, shape mismatch may still cause functional failure). During the disassembly and installation process, avoid hitting the weak parts of the special-shaped rings (such as thin walls, sharp corners), to prevent deformation and damage. Although the special-shaped rings of the air compressor are not universal, they play an irreplaceable role in special structural parts. Their design and manufacturing need to strictly match the specific requirements of the equipment, and special attention should be paid to precision and directionality during installation and maintenance to ensure the coordinated operation of all complex components of the air compressor.

Common Problems and Maintenance of Atlas Copco Oil Separator Reduced separation effect Reason: Filter blockage, damage, poor return oil pipeline, or excessively high temperature of the oil-gas mixture . Solution: Replace the filter, clean the return oil pipe, and check the cooling system to ensure the exhaust temperature is normal . Excessive pressure difference Sign: The pressure difference between the separator inlet and outlet exceeds 0.15MPa, resulting in reduced exhaust volume and increased energy consumption. Solution: Replace the filter in time to avoid filter damage or overload of the housing due to excessive pressure difference. Return oil failure Reason: Return oil valve blockage, throttling hole blockage, or leakage of the return oil pipe. Harm: The compressor operates without oil, causing wear of the main unit and sudden temperature rise. Solution: Disassemble and clean the return oil components to ensure smooth return oil.

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 2906037800，The intermediate cooler of the air compressor is an important component of the compressor unit, primarily responsible for three core functions: heat exchange, temperature control, and system protection. The cooling and heat dissipation process reduces the temperature of the high-temperature compressed air discharged by the primary compressor from 186°C to around 54°C, providing suitable temperature conditions for the secondary compression stage. It also cools the liquid temperature before it enters the main expansion mechanism, reducing throttling losses. It enhances the compression efficiency. It enables isothermal compression, optimizes compression efficiency, ensures the outlet pressure and temperature indicators, reduces heat loss, and improves the overall operational efficiency of the unit. System protection prevents the exhaust temperature from exceeding the allowable value due to excessively high suction temperature at the high-pressure stage, providing an oil separation function to separate the oil and moisture in the compressed air.
