Air compressors can be divided into two types according to different lubrication methods. One is oil-free air compressors and the other is oil-free air compressors. The latter uses lubricating oil to lubricate the parts to reduce the wear between the parts. The oil-free air compressor is not involved in the operation of the lubricating oil. Therefore, the compressed air is not polluted by the lubricating oil. Speaking of this, there are customer questions, oil-free air compressor does not need lubrication? Here to answer everyone's questions.
oil-free air compressor lubrication way is what?
Oil-free screw air compressor adopts advanced oil-free water lubrication single screw compressor technology, compared with dry twin screw air compressor, air compressor components are completely free of lubricating oil, ensure oil-free compression, provide reliable oil-free compressed air solutions.
Oil-free air compressor mainly uses water to replace oil, realizing the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality oil-free air, no pollution, and no special treatment for discharged water, which meets the requirements of environmental protection. Due to the role of water, its compression is an ideal isothermal compression. The gaps of various mechanical parts forming the compression chamber use the water film effect to prevent air leakage. The amount of air discharged is 25% more than that of a dry screw compression.
It should be noted that the compressed air of the oil-free air compressor is not 100% oil-free. Because the air contains a small amount of oil, the compressed gas also needs to be treated.
Only the water-lubricated air compressor produced by Shanghai granklin group does not need to be treated. because water lubrication is adopted, it can be used only by matching the cold dryer and air storage tank at the back end and configuring filters according to special needs.
The difference between an oil-free air compressor and an oil-free air compressor is seen from the oil content. The oil-free and oil-free air compressor generally refer to the oil content of the gas discharged from the exhaust port of the air compressor. Generally, the oil content of an oil-free air compressor is large, and the oil content of an oil-free air compressor is 0.01ppm, so
What is the root cause of the low gas production of the oil-free air compressor? During the operation of the oil-free air compressor, insufficient gas supply occasionally occurs. What is the reason? In fact, machine selection, air leakage, gas production standards, machine wear and other aspects may lead to gas supply
As the screw oil-free and water-lubricated screw air compressor is a stainless steel single screw main machine for the whole series, it can save more than 15% energy than the secondary dry twin screw and more than 36% energy than the primary twin screw. Oil-free screw air compressor reaches the energy-saving level of oil machine. Avoid frequent and high maintenance of dry screw. Energy saving: Grankering single-screw main engine with high volumetric efficiency is adopted, which has low specific power and is more efficient and energy-saving than twin-screw oil-free air compressors.
The water-lubricated air compressor produced by Shanghai Granklin Group is suitable for compressing nitrogen, argon, natural gas and other gases in safety and explosion-proof treatment. Safety explosion-proof air compressor Granklin Group has rich experience and can work stably for a long time in various scenarios.
View detailsWhat kind of oil is used in the air compressor? Does the oil-free air compressor not use lubricating oil? The oil-free air compressor refers to the use of lubricating oil (synthetic oil or semi-synthetic oil) in the air compressor system to lubricate the machine and dissipate heat. This kind of air compressor, the compressed air will have a certain amount of lubricating oil, that is, the post-processing equipment is used for filtration, but it is still
What brand of air compressor is good? These questions are many buyers are more concerned about the problem. Under the epidemic, the market downturn, business difficulties, the company's decision makers in the procurement of air compressor equipment is also a different mindset, air pressure.
The main functions of air compressors in the food industry are embodied in the following two aspects: (Granklin water-lubricated air compressors, food factories use 100% oil-free) 1. Avoid contamination of equipment and food. Because food production often depends on natural fruits, the shelf life of these fruits is very short, which has strict requirements on the air environment of food production equipment and products.
For the air compressors used in waste incineration, the power compressors for small and medium-sized enterprises are mainly small displacement, and the flow rate is mostly below 3m 3/min. The market share accounts for "half of the country" of screw compressors, and the stock market reaches millions of units. The screw relies on the gap to seal the gas and does not have good performance in the small flow range. Small and medium-sized enterprises are cost-sensitive users, very much hope to reduce the operating costs of small displacement screw compressors, small displacement screw compressor low energy efficiency has become a pain point for small and medium-sized enterprises.
