Comparison of oil-free air compressor and oil-injected air compressor

In general, oil-free air compressors are used in the food industry, because the food industry is relatively demanding. Oil-free air compressor is not only oil-free, I still give you a comprehensive popularization of the basic advantages of oil-free air compressor! First of all, the material of the machine itself does not contain oily substances, and there is no need to add any lubricating oil when working, so the quality of the discharged air is greatly improved, and the safety of the equipment required by the user is also guaranteed. Unlike the oil-injected air compressor, the discharged gas contains a large amount of oil molecules, which will cause different degrees of corrosion to the equipment supported by the user. Therefore, it is necessary to choose an oil-free air compressor to ensure air quality.

Secondly, the use and maintenance of oil-free air compressors are also more convenient and concise than oil-injected air compressors. As we all know, some oil-injected air compressors need to be replaced or added with air compressor oil regularly during the use of the machines, and some air compressors will have oil injection and oil leakage, which will cause pollution to varying degrees around the use environment and require users to spend time cleaning, which will relatively increase the workload of users, which is contrary to people's willingness to use machinery and equipment to improve work efficiency.

Compared with this kind of air compressor, oil-free air compressor basically does not need users to spend time to maintain, because it does not need to add a drop of oil, and the fully automatic pressure sensing switch will automatically start or stop according to the amount of air you use, which can be described as saving energy. The automatic drainage device also saves users a lot of worry, so it is very convenient to use. Life is also longer than the fuel injection air compressor! After investigation: users who have used oil-free air compressors have expressed their willingness to recommend such air compressors to friends!

In addition, with the rapid development of industry and the improvement of people's living standards, the society's requirements for the required products have been greatly improved. At the same time, the improvement of the precision of pneumatic components has prompted more and more requirements for the oil and water content of compressed gas. In the past, new products of oil-free air compressors were greatly restricted by quality problems. With the improvement of the quality of the oil-free air compressor, its quality has been fundamentally improved, which can fully meet the needs of modern industrial production. The superiority of the oil-free air compressor in the use process is reflected, as follows:

because of the high viscosity of the lubricating oil, the oil removal equipment cannot be completely removed, so that the oil-free air compressor compressed gas does not contain oil.

2. Water removal equipment such as refrigerated dryer, heat-free regeneration dryer and micro-heat regeneration dryer lose water removal function due to oil in compressed air. The clean oil-free gas compressed by the full oil-free compressor fully protects the water removal equipment and reduces the additional capital occupation caused by the maintenance of the water removal equipment.

3. Using an all-oil-free air compressor to provide compressed gas to the outside will not greatly reduce the motor load due to the pressure loss caused by oil removal equipment, thus achieving energy saving effect; A good 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 day of work (10 hours, for example), this will be a long-term intangible expense.

4. The use of oil injection air compressor greatly wastes lubricating oil. Take a 7.5KW high-quality oil injection air compressor as an example, it consumes a minimum of 5kg of lubricating oil per month, and will cost 60kg of lubricating oil more than one year. At the same time, in order to remove the oil in the compressed gas, it is necessary to use an efficient oil filter and replace the filter core many times, which is also a great expense.

Summary of the advantages of oil-free air compressor itself:

1. Compact structure, small size and light weight;

2. The exhaust is continuous and uniform, and there is no need for inter-stage intermediate tanks and other devices;

3, small vibration, less wearing parts, do not need a large and heavy foundation;

4, in addition to the bearing, the internal parts do not need lubrication, fuel, and do not pollute the compressed gas;

5. High speed;

6, small maintenance, easy to adjust.

7, quiet, green environmental protection, no noise pollution, no need to add lubricating oil.
