Is the screw air compressor always working?

Screw air compressor does not have to work all the time, but runs and shuts down according to actual needs. The following is a detailed explanation of the working state of the screw air compressor:

Working principle and characteristics

Screw air compressor is a volume compressor. The working volume composed of a pair of rotors placed parallel to each other and meshed with each other and a casing containing the pair of rotors is gradually reduced, so as to achieve the purpose of gas compression. It has the following characteristics:

  • Automatic adjustment: Screw air compressors are usually equipped with pressure control systems that can be automatically loaded and unloaded according to the set pressure value. When the system pressure is lower than the set value, the air compressor will automatically load and run, generating compressed air; when the system pressure reaches or exceeds the set value, the air compressor will automatically unload and run, reducing energy consumption and wear.
  • Frequency conversion technology: Some screw air compressors use frequency conversion technology, which can automatically adjust the motor speed according to the actual gas volume, thereby accurately controlling the output and pressure of compressed air and achieving energy-saving operation.

Working mode

  • Continuous operation: In some applications where compressed air demands are continuous and stable, the screw air compressor may need to operate continuously. However, this does not mean that the air compressor is always in full load operation state, but is automatically adjusted according to the system pressure.
  • Intermittent Operation: In most applications, screw air compressors operate intermittently. When the system pressure reaches the set value, the air compressor will automatically unload and run or shut down, and wait for the system pressure to drop before reloading and running.

Maintenance and Life

  • Maintenance and Maintenance: The screw air compressor needs regular maintenance, including replacing lubricant, cleaning the radiator, checking electrical connections, etc., to ensure the normal operation of the equipment and extend the service life.
  • Service life: The service life of a screw air compressor depends on a variety of factors, including equipment quality, service conditions, maintenance, etc. Rational use and maintenance can significantly improve the service life of the equipment.

Precautions

  • Avoid overload operation: The screw air compressor has certain load restrictions during design. Long-term overload operation will cause the equipment to overheat, wear and even damage.
  • regular shutdown inspection: Even if the air compressor is in an automatic loading and unloading state, it should be periodically shut down to check the operating status and performance of the equipment, and discover and deal with potential problems in a timely manner.

In general, the screw air compressor does not have to work all the time, but runs and shuts down according to actual needs. Through reasonable use and maintenance, the normal operation of the equipment can be ensured and the service life will be extended.
