How many hours does the screw air compressor need to be maintained

The maintenance cycle of screw air compressors is not fixed, but is affected by many factors, including the type of equipment, working environment, frequency of use and manufacturer's recommendations. Generally speaking, the maintenance cycle of screw air compressor can be roughly summarized as follows:

daily inspection and maintenance of 1.

• Daily maintenance:

  • check the oil level, exhaust temperature and exhaust pressure.
  • Check air filter element and coolant level.
  • Check hoses and all fittings for leaks.
  • Check the equipment for abnormal noise, abnormal vibration or overheating.
  • Check and record the replacement cycle of consumable parts, and stop the machine for replacement if necessary.
  • Check and drain the condensate.

• Weekly maintenance:

  • repeat the contents of daily maintenance.
  • Check whether the safety valve is working properly.
  • Check the belt for wear.

• Monthly maintenance:

  • check and clean the cooler.
  • Check all wire connections and fasten.
  • Clean the surface of the motor suction port and the surface of the housing from dust.
  • Clean the scavenge oil filter.

2. regular maintenance

• new machine for the first time maintenance:

  • it is usually carried out after about 500 hours of operation.
  • The main contents include replacing the oil filter, air filter element and lubricating oil.

• Regular maintenance cycle:

  • generally, the regular maintenance interval is about 2500 to 4000 hours, or more broadly, every 4000 to 8000 hours.
  • If the equipment is in a harsh environment, such as dust, high humidity or corrosive gases, or high frequency of use, it is recommended to shorten the maintenance cycle.

• Specific maintenance items:

  • lubricating oil replacement: Most air compressors need to be replaced every 2000 hours or every 3 months. It is also said that the lubricating oil should be replaced every 4000 hours or once a year.
  • Replace the air filter element: The air filter element needs to be replaced regularly to ensure the purity of the compressed air. Some sources indicate that air filters need to be replaced every 1500 to 2000 hours of operation, depending on the environment and manufacturer's recommendations.
  • Oil filter replacement: The oil filter replacement cycle ranges from every 500 hours to every 5000 hours, depending on the type of equipment, the use environment and the frequency of use. Generally speaking, the oil filter needs to be replaced after the running-in period (such as 500 hours of the first operation of the new machine), and it may be replaced in about 2000 hours for daily use.
  • Replace the oil and gas separator: The replacement cycle of the oil and gas separator is usually 3000 hours or more, but it depends on the use environment. It is recommended that the oil and gas separator core should be replaced every 4000 hours or more.
  • Other maintenance items: the dust on the surface of the radiator should be removed every 2000 hours to maintain good heat dissipation performance; at the same time, check and adjust the tightness of the belt to ensure that it is in the best condition. It is recommended to carry out a comprehensive major maintenance every 3000 hours or so, including the replacement of the above-mentioned key components.

3. considerations

• selection of high quality accessories: High-quality accessories are very important to extend the service life of the air compressor.
• Follow manufacturer's recommendations: The specific maintenance cycle and items should be determined according to the equipment's user manual and manufacturer's recommendations.
• Record maintenance accurate records are conducive to timely analysis and troubleshooting when the air compressor fails. The main contents of maintenance records include inspection, cleaning, adjustment, supplement, replacement and corresponding time.

In summary, the maintenance cycle of the screw air compressor should be considered comprehensively according to various factors such as equipment type, working environment, frequency of use, and manufacturer's recommendations. Regular maintenance and maintenance is essential to extend the service life of the screw air compressor and maintain its performance.
