Does permanent magnet frequency conversion water lubrication air compressor save electricity

When purchasing screw air compressors, we often pay more attention to whether the air compressors are free of oil after compressing the gas. It is not cost-effective to consider selecting some power frequency air compressors based on the principle of cost saving. We should not only consider the oil-free air compressors but also consider energy saving. Then the most suitable air compressor is water-lubricated air compressors. The air discharged by water-lubricated air compressors does not contain oil, which is the first choice for purchasing oil-free air compressors.

The water-lubricated air compressor produced by Shanghai Granklin Group is a screw-type air compressor, which is very consistent with the characteristics of stable gas supply and oil-free gas. In terms of energy saving, we can also choose water-lubricated permanent magnet variable frequency air compressor, which fully meets the needs of both oil-free and environmental protection and energy saving.

water-lubricated oil-free air compressor is one of the compressors. Its compression medium is air, and the compressor can be used to compress many things, not just air. The difference between water-lubricated oil-free air compressors and ordinary compressors, water-lubricated oil-free air compressors can be applied to some more special environments, such as food processing, textiles, chemicals, air separation, process gases, etc.

When many customers buy permanent magnet variable frequency screw air compressors, they all say that they hear that permanent magnet variable frequency screw air compressors are very energy-saving. How energy-saving is the permanent magnet variable frequency screw air compressor?

How much energy can permanent magnet variable frequency screw air compressor save than general air compressor.

Take the GW132VW water-lubricated permanent magnet frequency conversion screw machine produced by Shanghai Graclin Group as an example:

(132KW,8bar, displacement range: 6.75~22.52m & sup3;/min)

1. Frequency conversion constant pressure output of compressed air. If the outlet pressure level of compressed air is required to be 6bar, we can set the constant pressure to be 6bar, and adjust the operating frequency according to the customer's air demand to achieve the purpose of adjusting the operating power. Oil-free piston compressors need to set the pressure level to be 6 ~ 8bar, the pressure difference is at least about 2bar, and the pressure difference of 2kg requires more than 15% of electricity charge;

2. Permanent magnet frequency conversion technology can realize no unloading. Generally, ordinary compressors will have pressure fluctuation unloading. This part can be saved and generally accounts for about 13% to 15% of the total energy consumption;

3. Permanent magnet frequency conversion technology has no starting impact on the power grid, saving part of power consumption;

4, water lubrication oil-free screw machine almost no displacement attenuation can save part of the power consumption;

to sum up, it is theoretically calculated that the water-lubricated oil-free screw machine saves more than 30% of electricity compared with the oil-free piston air compressor. We calculate according to the actual electricity saving of 15%, running 24 hours a day and working 300 days a year: 15% X132X24X300 = 142560KWH
