With the continuous development and progress of society, energy conservation and emission reduction has become a topic of concern. Especially in the industrial field, all companies are actively adopting effective energy-saving measures.
Increase knowledge! Analysis of Energy Consumption Causes of Ordinary Power Frequency Air Compressors
As the basic product of industrial modernization, air compressor is an indispensable mechanical equipment in enterprise production. The air compressor converts electrical energy into air kinetic energy, and its power consumption is very large, especially the ordinary power frequency machine. Then, regarding the energy consumption of ordinary industrial frequency air compressors, let us discuss:
Power frequency start surge current
The power frequency air compressor adopts the star-delta starting mode and starts at 5-8 times of rated current. It has a large impact on the power grid, which is easy to cause grid instability and threaten the operation safety of other electrical equipment.
Power waste loading and unloading
Conventional air compressors continue to increase pressure until the pressure is unloaded after the pressure reaches the required working pressure. If the air compressor only needs 6kg of pressure, it must be hit 8kg, then reloaded when it is reduced to 6kg, so two wastes are generated. One is from 8kg to 6kg, the motor idling, causing serious no-load waste; the second is the pressure difference from 6kg to 8kg. According to reports, for every 1kg of pressure, the power consumption is 7%, and the 2kg pressure consumes 14%.
In addition, due to the limitation of the power frequency control mode, the motor can not start and stop frequently. Therefore, when the air consumption is small, the motor still needs to run at no load, and the power is wasted hugely.
Unsteady pressure, slow regulation
The frequency of the industrial frequency air compressor is low, and the adjustment of the output pressure is realized by the control of the loading and unloading valve and the regulating valve. The adjustment speed is slow, the fluctuation is large, the precision is low, and the output pressure is unstable.
Accelerated wear and maintenance
The working mode of power frequency control determines that the loading and unloading valve must repeat the action, and the components are easy to aging. The continuous power frequency and high speed operation not only makes the noise loud, but also accelerates the wear of the bearing and the maintenance of the equipment is large.
After the energy-saving retrofit of the traditional air compressor, the air pressure output of the air compressor can be matched with the air volume required by the user air system to achieve constant pressure air supply, soft start operation, and reduce air compressors and other electrical equipment. The impact, enhance the stability of the air compressor, reduce power consumption, and achieve energy saving and consumption reduction of the air compressor.
