The impact of air compressor consumables on air compressor energy consumption

 

As we all know, the three most important consumables of an air compressor are air filter, oil filter and oil separator. However, what most people may not understand is that air compressor consumables can also affect the energy consumption of the air compressor. So how do these three factors specifically affect the energy efficiency of air compressors?

 

1. The impact of air filter on air compressor energy efficiency

 

Air filtration mainly affects energy efficiency in two aspects:

1. Filtering accuracy. If an air filter with low filtration precision is used, a large amount of dust will be inhaled. In addition to affecting the quality of lubricating oil and air compressor parts, the dust will be adsorbed on the surface of the oil, which will quickly increase the internal pressure of the oil (especially when the user uses When the environment is very poor), the pressure difference between the middle and later stages of oil separation is very large. Many people know that one kilogram of oil pressure difference increases power consumption by 7%. Using a high-quality air filter with high filtration accuracy can greatly reduce the oil pressure difference in the middle and later stages, thereby improving the energy efficiency of the air compressor.

 

1. Inspiratory resistance. I believe everyone knows that the greater the suction resistance, the lower the energy efficiency of the air compressor. However, many people only know that the air filter is clogged when they find that the air compressor no longer pumps air, or that the air filter has been sucked and exploded. In fact, this is not the most terrifying time. The most terrifying thing is that for a long time before the air filter is completely clogged or the air filter explodes, everyone fails to discover in time that the suction resistance of the air filter is already very large, and fails to clean or replace the air filter in time. A lot of electricity was wasted.

 

2. The impact of oil filter on air compressor energy efficiency

 

There are three main aspects of the impact of oil filter on air compressor energy efficiency:

1. Oil filter dust holding capacity. Many people mistakenly believe that the oil filter is based on the interception filtration principle, and that the higher the filtration precision, the better. In fact, the oil filter is based on the adsorption filtration principle, and the filtration precision does not need to be too high. Lubricating oil is a viscous liquid. It is not good if the filtration precision is too high. Medium filtration precision is sufficient. The filtration effect of the oil filter mainly depends on the dust holding capacity, not entirely on the filtration accuracy of the oil filter. An oil filter with a large dust holding capacity has relatively small resistance in the middle and late stages. The smaller the resistance, the higher the energy efficiency.

 

1. Oil filter resistance. If the filter paper is of poor quality and the permeability is not strong, the resistance will become larger and larger after being used for a period of time, which will also have an impact on the energy efficiency of the air compressor.

 

1. Anti-aging ability of oil filter. An oil filter with weak resistance to aging will not only fail to filter in the middle and later stages, but will also form new sources of pollution after carbonization of the filter paper, increase the oil partial pressure difference, and reduce the energy efficiency of the air compressor. Choosing a high-quality oil filter not only has a good filtration effect, but also helps to improve the energy efficiency of the air compressor.

 

3. The impact of oil content on air compressor energy efficiency

 

The main impact of oil content on air compressor energy efficiency is the oil pressure difference. The pressure difference between oil content and oil content will affect the air compressor energy efficiency:

 

1. Initial pressure difference. Generally speaking, the initial pressure difference between oils produced by different manufacturers and methods is generally not very different, generally the difference is 0.1 to 0.2 kg. Therefore, the difference in the impact of oils produced by different manufacturers and methods on energy efficiency will not be particularly large. Of course, if an oil with a lower initial pressure difference is used, the energy efficiency will be slightly higher.

 

1. Pressure difference between the middle and later stages of oil content. If the pressure difference between the middle and late stages of oil separation is low, the energy efficiency of the air compressor will be greatly improved; conversely, if the pressure difference between the middle and late stages of oil separation is large, the energy efficiency of the air compressor will be greatly reduced. The problem of large pressure difference in the middle and late stages of oil separation is generally caused by four aspects: the filtration accuracy of the air filter is too low, and too much dust is sucked in; the quality of the lubricating oil is too poor, resulting in excessive carbon deposits; the air is humid or the operating temperature is too low, etc. , resulting in too much water in the system; the oil content is due to its own design and manufacturing. In order to cater to air compressor dealers, a few oil manufacturers simply pursue low oil content, which leads to high internal pressure in the middle and later stages of oil content.
