Screw air compressor does not have to work all the time, But run and shut 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 positive displacement compressor. The purpose of gas compression is achieved through the gradual reduction of the working volume composed of the cogging grooves of a pair of rotors placed parallel to each other and meshing with each other and the casing containing the pair of rotors. It has the following characteristics:
- automatic adjustment: Screw air compressors are usually equipped with a pressure control system, which can automatically load and unload according to the set pressure value. When the system pressure is lower than the set value, the air compressor automatically loads and runs to produce compressed air; when the system pressure reaches or exceeds the set value, the air compressor automatically unloads and runs to reduce energy consumption and wear.
- frequency conversion technology: Some screw air compressors adopt frequency conversion technology, which can automatically adjust the motor speed according to the actual air consumption, so as to accurately control the output and pressure of compressed air and realize energy-saving operation.
Working mode
- continuous operation in some applications where the demand for compressed air is continuous and stable, the screw air compressor may need to run continuously. However, this does not mean that the air compressor is always running at full load, but automatically adjusts the operating state according to the system pressure.
- Intermittent operation: In most applications, the screw air compressor operates in an intermittent mode. When the system pressure reaches the set value, the air compressor will automatically unload or shut down, and then reload after the system pressure drops.
MAINTENANCE AND LIFE
- maintenance: The screw air compressor needs regular maintenance, including replacing the lubricating oil, cleaning the radiator, checking the electrical connection, etc., to ensure the normal operation of the equipment and extend the service life.
- Service life the service life of the screw air compressor depends on many factors, including equipment quality, use conditions, maintenance, etc. Reasonable use and maintenance can significantly improve the service life of the equipment.
Precautions
- avoid overload operation: The screw air compressor is designed with a certain load limit. Long-term overload operation will cause the equipment to overheat, increase wear and even damage.
- Regular shutdown inspection: Even if the air compressor is in the automatic loading and unloading state, it should be stopped regularly to check the operating status and performance of the equipment, and find and deal with potential problems in time.
In general, the screw air compressor does not have to work all the time, but runs and stops according to actual needs. Through reasonable use and maintenance, the normal operation of the equipment can be ensured and the service life can be extended.
