China Air compressor VALVE Manufacturer, Supplier, Factory

Atlas Copco 2901069501,The function of the Atlas Copco air compressor filter is to filter impurities. It mainly filters dust, particles, oil mist and moisture in the compressed air to prevent them from entering the air compressor system, thereby protecting the main unit and downstream equipment from malfunction and ensuring their normal operation. This protects the equipment from wear, corrosion or failure caused by impurities, and extends the service life of the air compressor. It ensures the air quality by guaranteeing that the compressed air meets the cleanliness requirements for production or use scenarios, such as in pharmaceutical and food processing industries where air quality is sensitive.

Our genuine Compressor Oil Filters are made from corrosion-resistant materials that lengthen your compressor oil lifetime. Its bypass valve guarantees a continuous oil flow to the compressor element, even in cold-start conditions or in the event of a clogged filter! High-quality synthetic filter paper: temperature and compressor oil-resistant, high-performance, and finely textured. High dirt-holding capacity to extend service intervals while protecting the compressor element. Uniform paper pleat spacing and increased mechanical resistance to pressure fluctuations, resulting in a safer working environment

Atlas Copco 1900520013 Work mode Atlas Copco 1900520013 Constant pressure control: Maintains the exhaust pressure within the range of the set value ±0.1bar, Atlas Copco 1900520013 suitable for precision gas usage scenarios Atlas Copco 1900520013 Load/unload mode: Unloads when the pressure reaches the upper limit and loads when it drops below the lower limit. Higher energy consumption Atlas Copco 1900520013 Variable frequency control: Achieves stepless speed regulation by adjusting the motor frequency, with significant energy-saving effect (15-35% more energy-efficient than fixed-speed models) Atlas Copco 1900520013 Multi-machine linkage: Multiple air compressors work together, automatically distributing the load according to the total gas usage demand

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.
