A power frequency air compressor is an air compressor driven by a fixed frequency (usually 50Hz or 60Hz) power supply. Its operating speed and output power are relatively fixed and cannot be automatically adjusted according to actual gas demand. The following provides a detailed introduction from the aspects of characteristics, applicable scenarios, advantages and disadvantages:
Characteristics
Fixed frequency operation: The industrial frequency air compressor is directly connected to the industrial frequency power supply and operates at a constant speed, which cannot automatically adjust the speed according to changes in gas consumption like the variable frequency air compressor.
Simple structure: relatively simple design, few components, mature manufacturing process, and low cost.
Easy maintenance: Due to its simple structure, daily maintenance and repair are relatively easy, spare parts have strong universality, and replacement is convenient.
Application
In situations where gas consumption is stable and continuous, such as large continuous production factories in industries such as chemical, metallurgical, and power, the demand for compressed air in their production process is relatively stable and continuous. Power frequency air compressors can meet their long-term, high flow gas demand.
For price sensitive applications: For users with limited budgets and not particularly high requirements for compressed air quality, power frequency air compressors are a more economical choice.
Advantages
Low initial investment: Compared to variable frequency air compressors, the purchase cost of industrial frequency air compressors is lower, making it a more economical choice for some financially limited enterprises.
Low maintenance cost: Due to the simple structure of the machine, the cost of maintaining and repairing the power frequency air compressor is relatively low.
Low noise: Compared to permanent magnet variable frequency air compressors, power frequency air compressors have lower noise levels.
Easy maintenance: Compared to permanent magnet variable frequency air compressors, maintenance and management of power frequency air compressors are simpler.
