Atlas Copco 1604530702,The main functions of lubricating oil are lubrication and reduction of friction. It forms a protective film between moving parts, reduces the friction coefficient, minimizes wear, and extends the lifespan of equipment. It also cools and dissipates heat, absorbs and removes the heat generated by friction, prevents the equipment from overheating, and ensures stable operation. It seals and prevents leakage, fills the gaps between components to prevent gas leakage and impurities from entering, and improves the sealing performance. It prevents rust and corrosion, forms a protective film on the metal surface to resist oxidation and water erosion, and avoids rusting. It cleans and buffers, removes impurities and deposits them at the bottom of the oil tank, and absorbs impact loads to reduce vibration.

Maintenance precautions for the load reduction device kit of Atlas Copco air compressors: Regularly clean the internal components of the load reducer to prevent the accumulation of oil and impurities, which could cause valve sticking or malfunction. Check the integrity of the seals and replace aging parts in time to avoid pressure control accuracy being affected by leakage. During commissioning, calibrate the pressure setting value according to the equipment manual to ensure accurate loading/unloading switching and avoid frequent start-stop or excessive pressure fluctuations.

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.

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

If you need to purchase Atlas Copco products or replace the screws of Atlas Copco air compressors, it is recommended that you select products with matching specifications and performance based on the model of the air compressor, specific components, and the regulations in the equipment manual, in order to ensure the safe and stable operation of the air compressor.

Characteristics and Requirements of Air Compressor Gaskets Sealing: They should have good elasticity and adhesion, being able to tightly fill the minute depressions on the joint surface under pressure, ensuring no leakage. Temperature Resistance: They need to be able to withstand temperature changes during the operation of the air compressor (especially the higher temperatures of the cylinder body, exhaust pipelines, etc.), avoiding aging, hardening or losing elasticity under high temperatures. Pressure Resistance: They can withstand the rated pressure of the compressed air (usually 0.7-1.6 MPa) and instantaneous impact pressure, preventing being punctured by the pressure. Media Resistance: When in contact with the lubricating oil in the air compressor, the cooling liquid, or the trace impurities in the compressed air, they should have anti-corrosion and anti-swelling properties. Abrasion Resistance and Anti-Aging: During long-term use, they need to resist the effects of friction and environmental factors (such as humidity, oxidation), maintaining stable performance
