Does oil-free air compressor need frequency conversion
Whether the oil-free air compressor needs to be equipped with frequency conversion depends mainly on your actual gas usage scene. Not all cases must be equipped with frequency conversion, which can be judged according to your own working conditions:
no need to install frequency conversion
if your production is stable for a long time, the air compressor is almost always running at full load, and there is almost no fluctuation in gas demand, there is no need to match frequency conversion. The conventional operation mode is more cost-effective and can also reduce the initial equipment input cost.
It is suggested to match the frequency conversion
if the daily gas demand fluctuates greatly and the amount of compressed air required at different times varies significantly, it is more recommended to allocate frequency conversion, which mainly has these benefits:
save energy consumption and reduce electricity costs
when the traditional oil-free air compressor has low gas demand, it can only rely on frequent loading and unloading or emptying of excess gas to adjust, which will waste a lot of electric energy. Frequency conversion can adjust the motor speed according to the actual gas consumption, and output as much gas as it uses, thus avoiding ineffective energy waste and saving a lot of electricity charges for long-term use.
Stable gas supply pressure to ensure production
frequency conversion can adjust the output in real time, so that the gas supply pressure has been kept stable, and the pressure will not fluctuate greatly due to changes in gas consumption, which can better ensure the stability of the production process and avoid unstable air pressure affecting product quality.
Reduce equipment loss and extend life
frequency conversion can realize soft start and soft stop of the motor, reduce the impact on the power grid and equipment when starting, and also reduce the wear caused by repeated opening and closing of the valve and frequent stress on the components, which can extend the overall service life of the equipment and reduce the workload of daily maintenance. At the same time, the speed is lower when the frequency conversion is running, and the noise generated by the operation can be reduced.
Advantages of collocation with water-lubricated oil-free air compressor
the water-lubricated oil-free air compressor itself uses water for lubrication, cooling and sealing, the compression process is closer to the ideal compression state, and its energy efficiency is higher than that of other oil-free models. After matching with frequency conversion technology, the energy-saving advantage can be further enlarged under the working condition of gas fluctuation, frequent loading and unloading are not required, additional energy consumption loss is also reduced, and the overall operation cost will be lower.
