How often should the air compressor run?

The best operating frequency of air compressor needs to be combinedEquipment type, gas consumption mode, maintenance costComprehensive assessment, the following are specific strategies:

I. Continuous operation scenario (recommended)

  1. applicable conditions
    • Continuous gas demand (such as production line, hospital oxygen supply)
    • The displacement volume of a single air compressor is greater than 60% of the peak air consumption
    • Equipped with frequency conversion controller or intelligent joint control system
  2. advantages
    • Avoid bearing impact caused by frequent start and stop (extend life by 30%-50%)
    • Maintain stable system pressure (fluctuation <±0.02bar)
    • Reduce condensate generation (40% increase in dryer efficiency through continuous operation)

2. Intermittent operation scenarios (need to be optimized)

  1. applicable conditions
    • There is intermittent demand for gas (such as laboratories, auto repair shops)
    • The displacement of a single air compressor is greater than 120% of the peak air consumption
    • Configure air storage tank (capacity ≥ average air consumption ×10 minutes)
  2. operation strategy
    • start threshold: Start when pressure <set value-0.2bar
    • shutdown threshold: Stop when pressure> setpoint +0.1bar
    • minimum run time: Run for at least 15 minutes after each startup (avoid carbonizing of lubricating oil)

3. Maintenance operation requirements

  1. Long-term downtime risk
    • Lubricating oil oxidation: stop>1 month to replace lubricating oil
    • Internal corrosion: shutdown>3 months need to do rust prevention treatment
    • Seal aging: shutdown>6 months to check the valve seal
  2. proposed package
    • Run at least once a week (when ambient temperature>20℃)
    • Running time>30 minutes (loaded state)
    • Drain condensate and check oil level after operation

4. Special environmental adjustments

environmental characteristics Operation policy adjustments
High humidity (>70%) Increase operation frequency and shorten downtime
High temperature environment (>40℃) Mandatory operation to cool down during night low temperature periods
High altitude (>3000m) Extend loading time and increase lubrication frequency

Can the fixed frequency screw compressor adjust the frequency?

The fixed-frequency screw compressor itself cannot adjust the frequency, but it can achieve stepless speed regulation through frequency conversion. It is necessary to comprehensively evaluate renovation costs, energy efficiency improvements and long-term maintenance needs to select the best solution. For newly purchased equipment, it is recommended to directly purchase inverter models to match dynamic gas demand.
