The main functions of the intake valve of Atlas Copco mobile air compressors
Dynamic adjustment of air intake volume: According to the variable gas demand during mobile operations (such as intermittent use of pneumatic tools), the air intake volume entering the compressor main unit is adjusted in real time, switching flexibly between full load and partial load to avoid ineffective energy consumption.
Protection for mobile conditions: When starting, it remains closed or slightly open to reduce the starting load of the mobile unit in bumpy, tilted, etc. conditions, protecting the engine (diesel / gasoline-driven) and compressor main unit.
No-load unloading: When the system pressure reaches the upper limit, the intake valve closes and opens the unloading channel, allowing the compressor to enter no-load operation, reducing fuel consumption (for power-type mobile units), and avoiding safety risks caused by excessive pressure.
Anti-pollution design: Some models integrate primary filtration functions, reducing the entry of dust, moisture, and other impurities into the main unit during field operations, adapting to harsh environments.
Structural and performance features
Structural adaptability: Mostly adopt compact butterfly valve or piston structure, with small size and light weight, suitable for the limited installation space of mobile units; valve body materials are mostly high-strength aluminum alloy or cast iron, resistant to vibration and impact, suitable for transportation and operation in bumps and tilts.
Drive mode: Depending on the model, it is divided into mechanical type (driven by pressure difference and spring) and pneumatic type (driven by control air path), some large mobile units adopt electronic control type, which can be linked with the unit PLC to achieve more precise regulation.
Environmental performance: Sealing parts use materials resistant to high and low temperatures and aging (such as fluororubber), able to adapt to temperature fluctuations in field operations (-10℃ to above 50℃); valve body surface is treated for anti-corrosion, resistant to moisture, dust, etc. environmental erosion.
Fast response: The valve core is sensitive, with a short response time from closing to full opening, capable of quickly matching sudden large flow gas demand (such as the startup of impact wrenches, pneumatic hammers, etc.).
Applicable models and application scenarios
Mainly compatible with Atlas Copco XAS (electric / diesel mobile screw compressors), XRVS (high-pressure mobile units), etc. Different power models (such as 18kW, 37kW, 75kW, etc.) correspond to different sizes and air intake volumes of the intake valve.
Widely used in mobile scenarios such as construction, mining, oilfield operations, emergency repairs, etc., providing stable air sources for pneumatic tools, sandblasting equipment, pipeline cleaning, etc.
