China Atlas Copco THERMOSTAT 40°C Manufacturer, Supplier, Factory

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 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.

Failure causes and maintenance suggestions for Atlas Copco Air compressor O-ring Common failure causes: Long-term high-temperature aging leads to reduced elasticity, wear or scratches (such as impurities entering the sealing surface), improper installation (such as twisting, being too tight), incorrect selection (material not suitable for the medium or temperature). Maintenance precautions: Regularly inspect the condition of the O-ring. Replace it promptly if it shows signs of hardening, cracking, deformation or leakage. When replacing, clean the sealing groove and mating surface, remove oil stains, burrs and impurities. Avoid using sharp tools to scratch the O-ring during installation. If necessary, apply special lubricating grease (compatible with the medium) to assist in installation. Select matching specifications and materials for the O-ring based on the air compressor model and location.It is recommended to use original factory parts to ensure the sealing effect.
