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.
Buy products preferred big brand, good service quality manufacturers. From foreign to domestic, there are only a few enterprises that can make water-lubricated air compressors in the screw air compressor industry. "Shanghai granklin Group" is one of them. granklin Do not forget your initiative mind strove forward on the road of water-lubricated air compressors.
According to China Electric Power News Network on September 23, the first centralized compressed air supply project in Shaoxing Binhai Industrial Zone, Zhejiang Province, has officially landed and is about to start construction. After the completion of the project for the surrounding 56 printing and dyeing enterprises to provide nearly 3000 standard cubic meters per minute compression
Oil-free, oil-free air water-lubricated screw air compressors are becoming more and more popular in the market, so what are the options for manufacturers of this series of screw air compressors? Shanghai Granklin Group is a professional manufacturer of "screw air compressors", as a brand enterprise. Granklin production of water-lubricated screw air compressor, oil-free air compressor market sales are rising year by year, more and more popular with users.
Many customers in the purchase of oil-free screw air compressor when they do not know what makes a good oil-free screw air compressor, then let us understand the following, when users buy oil-free screw air compressor should mainly choose from the quality and function. Specific can be considered from the following aspects:
View detailsA large amount of data shows that the main cost of compressed air system is spent on operation. In its life cycle, operating costs (electricity) account for 78 to 92%. Therefore, how to tap the potential of energy consumption and improve energy efficiency through fine management is a must for every enterprise.
Shanghai granklin group has many cases in the food industry. food factories that need oil-free screw air compressor can contact us for inquiry. In recent years, the food industry has developed rapidly, and the automation level of food factory equipment has also been continuously improved. Machine, electricity, gas and other integrated technologies are increasingly applied to the food industry, oil-free screw air compressor is one of them.
View detailsGranklin Group is a manufacturer of water-lubricated oil-free air compressors, when the hospital procurement may have questions about the water-lubricated oil-free air compressor, is it suitable for hospital use? When the water-lubricated oil-free air compressor is deployed to the medical system, it is the most basic condition that the procedures and documents are complete.
View detailsThe price of "oil-free air compressor" is the standard that we care about very much when we buy "screw air compressor". No one's money is blown by strong winds. Of course, according to different power and exhaust volume, the price of "oil-free air compressor" will inevitably vary greatly. This problem should be specific in the actual parameters, and colleagues should also consider it comprehensively. The choice of "oil-free air compressor price", which is cheaper without considering other factors, may fall into traps and troubles. Different from other brands.
The water-lubricated oil-free 5.5 kW screw air compressor produced by Shanghai granklin Group is neither big nor small. Compared with high-power models, 5.5 kW air compressor is already mini. The size of the machine means that the internal structure needs reasonable distribution. When purchasing water-lubricated air compressors, small models will drink less, whether they are freight or accessories, etc. Therefore, some customers do not need to consider this freight when purchasing air compressor equipment. A small forklift truck can fork hundreds of kilograms of equipment.
View detailsAir compressor which brand is good? If you don't care about the price, it is certainly good to buy air compressors in Europe and America and Japan. But in the case of limited budget, the preferred domestic air compressor brand words, recommended Shanghai Granklin Group. Granklin air compressor brand, in the domestic price is still very high. Fully independent production of air compressor head, quality assurance, after-sales is also very good.
