Several advantages of oil-free air compressor, as well as the difference between oil-free air compressor and oil-free air compressor.
See their differences specifically:
oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, this oil content is used to distinguish the oil and no oil in the air compressor. There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of water lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.
Oil-free screw air compressor really oil-free?
Let's look at the advantages of oil-free air compressors.
1. the current refrigeration dryer, no heat regeneration dryer, micro heat regeneration dryer and other water removal equipment, due to the oil in the compressed air and loss of water removal function; and the clean oil-free gas compressed by the oil-free compressor, fully protect the water removal equipment, reduce the maintenance of water removal equipment caused by the additional capital occupation.
2., the use of oil air compressor greatly wastes lubricating oil. Taking a 7.5KW high-quality oil air compressor as an example, it consumes a minimum of 5kg of lubricating oil per month, and will pay an extra 60kg of lubricating oil for a year. At the same time, in order to remove the oil in the compressed gas, an efficient oil filter needs to be used, and the filter core needs to be replaced many times, which is also a great expense.
3. because of the high viscosity of the lubricating oil, the current oil removal equipment cannot be completely removed, so that the oil-free air compressor compressed gas does not contain oil.
4. oil-free air compressor is used to provide compressed gas to the outside, the motor load will not be greatly reduced due to the pressure loss caused by oil removal equipment, thus achieving energy saving effect. At present, the high-quality three-stage oil remover will produce a pressure loss of 1 to 1.2kg during use. A 7.5KW air compressor will pay an extra 600W of power loss for every 1kg of pressure increase, and 6 degrees of electricity for every working day (10 hours, for example), this will be a long-term intangible expense.
Summary:
in fact, each air compressor has its own advantages and disadvantages. When choosing, it should make a suitable choice according to its own needs. There is no absolute rule. Only by recognizing the advantages and disadvantages of each air compressor can make a full understanding of the choice.
On the whole, it is more cost-effective to purchase water-lubricated air compressors. After all, water-lubricated air compressors are better than traditional oil-injected air compressors in terms of maintenance and gas.
shanghai granklin group specializing in the production of water lubricated air compressor, factory sale air compressor after sale is guaranteed.
Compressed air is widely used and is the second largest power energy after electricity. Therefore, air compressors, as general equipment, are widely used in various industries. Air occupies a certain space, but it has no fixed shape and volume. In the right
The compression types of air compressors can be divided into three types: if there is a dryer in the air compressor room, the air storage tank must be installed before the dryer, so that the compressed air discharged from the air compressor can be properly buffered before entering the dryer And cooling, the dryer needs to have
The perfect air compressor does not exist, has the ability to continuously improve the air compressor technology manufacturers, constantly improving equipment, through service to achieve relative perfection. Now the permanent magnet variable frequency air compressor is basically being done by all manufacturers. Where
The filter elements of the air compressor include air filter, oil filter and oil filter. The three perform their respective duties and play different roles. Any failure of the filter element may cause problems in the operation of the air compressor. Today we will talk about the three filter elements of the air compressor. The air filter element and oil filter element of the air compressor are made of high-precision filter paper. Under normal circumstances, the service life is about 2000 hours. The filter element must be replaced as soon as possible to avoid damage to the host.
View detailsAs a special type of air compressor, Shanghai Granklin water-lubricated oil-free air compressor is widely used in laboratories, hospitals and other industries with high requirements for compressed air quality. For repair and maintenance, oil-free air compressor also has some different requirements from other air compressors. Granklin air compressor summarizes the following suggestions for your reference:
With the deepening of market economy reform and increasingly fierce market competition, the food industry has put forward higher requirements for food quality. The air compressor in the food industry is a high-tech technology that is produced in order to ensure the sanitary environment and quality assurance in the food production process.
As the country pays more and more attention to energy conservation and emission reduction (fashionable name is carbon neutral), the application of low-pressure screw air compressor is also increasing. At present, there are three main types of low-pressure screw machines: dry screw, water spray screw, and oil spray screw.
The disadvantage of water lubrication is that the requirements for lubricating water are relatively high. For example, the advantages of pharmaceutical factories to meet the standard of production water are energy saving, low follow-up maintenance cost and less consumables. Only air filter and water filter without oil, as the name implies, are air compressors that do not use oil lubrication to produce
"7.5kw air compressor" in the industrial "industrial screw air compressor" is not big, because as "Shanghai granklin group" production of a larger "air compressor", it has the characteristics of simple maintenance, stable gas supply. Small "air compressor" models are more popular in small and medium-sized enterprises, especially "7.5kw air compressor".
The air storage tank is a special equipment, and the air compressor manufacturer will inform the service life, which is basically 10 years. Gas storage tanks that are not more than 10 years old cannot be used. If they are more than 10 years old and have been submitted for inspection to the Quality Supervision Bureau every year, it is still acceptable.
