Compare with the Advantages and Disadvantages about 4 Types of Compressors
The air compression system can be divided into air compressor, compressed air post-treatment, circulating water system, compressed air transmission and control system, etc. If the air end of the air compressor is a car, the compressed air transmission and control system is the road. Without a good road, no matter how good the car is, it can't run fast. Compressed air delivery and control system will directly affect the delivery capacity of compressed air, air pressure control capacity and energy consumption of compressed air system in the future.
Among the users with large air consumption, it is a common choice to configure the centrifugal air compressor as the main air end. According to the fluctuation range of air consumption, it is a common choice to use the air compressor with frequency conversion technology as the auxiliary machine for regulation. The automatic unattended station and digital monitoring data system are being popularized and applied by many manufacturers. As for the main air end, several types of equipment, such as centrifugal air compressor, oil-free screw air compressor, frequency conversion oil-free screw air compressor and magnetic levitation frequency conversion centrifugal air compressor, have their own technical characteristics and application scope.
Centrifugal Air Compressor
Advantages: large air production of single machine, lowest relative price, low specific power of loading and operation, high efficiency and low operation cost.
Disadvantages: small load adjustment range, high energy consumption during unloading, long loading / unloading time and high machine noise.
Oil Free Screw Air Compressor
Advantages: there are few maintenance parts, the flow is adjusted through the loading / unloading valve, the adjustable range is large, and the standard sound insulation cover is equipped with low noise.
Disadvantages: the price is higher than that of centrifuge. In the process of loading and unloading regulation, the pressure bandwidth is large, resulting in large energy waste and large efficiency attenuation in the normal service cycle of the equipment.
Oil Free VSD Screw Air Compressor
Advantages: less maintenance parts, stable process during load change through frequency conversion adjustment, lower output specific power than oil-free screw air compressor, large adjustable range, standard sound insulation cover and low noise.
Disadvantages: the price is high and the efficiency attenuation is large during the normal service cycle of the equipment.
Magnetic Levitation Centrifugal Air Compressor
Advantages: low specific power for loading and operation, high efficiency, lowest unloading power, rapid loading and unloading, low noise, few maintenance parts and low operation cost.
Disadvantages: the price is slightly higher and the pressure is not high.
