Energy-saving principle of frequency conversion air compressor

Energy-saving principle of frequency conversion air compressor

In recent years, with the continuous improvement of the global energy prices, energy-saving products more and more attention of the industrial enterprises. Air compressor as a power-hungry industrial enterprises, its economy running more and more importance in enterprises. Frequency conversion to adjust the air compressor has been widely welcomed its excellent operating efficiency in industrial enterprises.

The vast majority of the use conditions, there is great fluctuation of the user of the compressed air demand. Traditional air compressor by adjusting the air compressor inlet valve to regulate the flow of the air compressor, the air compressor gas production and the user's actual demand balance. This adjustment regulation is inefficient, leading to a lot of wasted energy. Frequency conversion air compressor by adjusting the frequency of the power to regulate the speed of the compressor motor, thereby regulating the speed of the air compressor host so the actual output of the air compressor gas and customer's actual gas consumption to reach consensus. The flow regulator can avoid a lot of wasted energy in the inlet flow rate adjustment method is the most efficient air compressor flow regulation on the market. The principle of frequency conversion air compressor system as shown below, currently on the market, all series of frequency conversion air compressors are based on the principles of design and manufacturing.

Inverter air compressor to deliver benefits

Inverter air compressor to subvert traditional air compressor operation control, has brought many benefits to the customer.

1 low start-up current: adjustable motor speed, the inverter compressor starts gradually accelerate from low speed, low starting power, the starting current is small, smooth start, no impact on the power grid, the unit can be use in the area of ​​grid capacity is relatively low.

Occasions, the use of energy saving / Save money: there is a change in the user gas consumption

Frequency conversion unit, to the maximum extent possible to avoid crew uninstall run there is no waste of electricity, the energy saving effect is obvious. The entire life cycle of the air compressor, compared with the conventional non-inverter air compressor, the average frequency conversion air compressor can save about 35% of electricity, equivalent to 22% of the total cost of air compressor.

Pressure stability: the rotational speed of the motor can be precisely controlled, fast response speed varies with the pressure, so the air compressor of the exhaust gas pressure fluctuation is small, the user can be used in more stable and lower pressure subzonally units; the same time, the user can configure a smaller gas tank to further cost savings.

Other issues related to frequency conversion air compressor

Frequency conversion air compressor Although there are many benefits, but also a lot of information has also repeatedly raised, but here was to make the following two pay attention, to avoid air compressor user to enter some misunderstanding.

An inverter air compressor particularly applicable to larger changes in gas consumption occasions, if the user changes in the gas consumption is very small, the gas is very stable, the use of the energy saving effect of the frequency of the air compressor is not very obvious. The energy saving effect is good or bad inverter air compressor and gas mode.

Frequency range of inverter air compressor and gas adjustment range is limited, not necessarily the bigger the better. The reason is that only a small range of efficient air compressor host speed zone, the greater the range of variable frequency adjust its edge to leave the host efficient speed zone farther, the lower the efficiency of the host. In addition, on the motor will have the same problem, so the overall efficiency of the units in the lower speed will be significantly reduced. In general, the frequency conversion air compressor frequency control range of 40-100% is the most valuable
