AI Technical Summary
Traditional nitrogen generator units rely on electronic frequency converters or manual adjustments to cope with fluctuations in downstream gas loads, resulting in high energy consumption, rapid mechanical wear, and insufficient reliability in scenarios without a stable power supply.
By employing automatic adjustment components and damping buffer components, and through the mechanical linkage of piston plates, toothed plates and gears, combined with a damping mechanism, the intake volume is automatically adjusted, replacing electronic frequency conversion control, eliminating power fluctuations and the lag of manual adjustment, and reducing the frequent start-stop of the air compressor.
This technology reduces energy consumption and extends the lifespan of mechanical components in nitrogen generator units even without a stable power supply, avoiding regulation failures and mechanical wear caused by power fluctuations and load changes.
