In the food and beverage, medicine, precision processing and electroplating, painting, foaming and other industries of gas-assisted equipment, people with work experience should know that clean oil-free compressed air is one of the essential resources for manufacturing.
Friends who have come into contact with "Shanghai granklin group" all know that granklin is an enterprise engaged in "water lubricated air compressor", specializing in the production and research and development of "oil free air compressor.
On the road of "oil-free air compressor", granklin group has been running for many years. friends who do not know anything about oil-free air compressor can contact us by phone and slowly understand what oil-free air compressor is.
Air compressor with and without oil
from the perspective of energy conversion, the acquisition process of compressed air is to convert mechanical energy into internal energy, that is, pressure potential energy. All types of air compressors convert mechanical power into pneumatic power by continuously concentrating air in the compression stage.
Such a continuous operation process requires considerable force and energy to complete. Whether it is oil injection lubrication or oil-free compressor, these heat will exist due to energy conservation. Therefore, they all need lubrication and cooling to prevent local high temperature deformation of the compressor, and then wear and damage. In other words, oil-free air compressors also need to use oil to lubricate their moving parts and take away the heat generated by moving friction.
So, how does the "oil-free" of the oil-free air compressor come from? Simply put, the oil-free air compressor does not use oil in the compression stage, and the oil will not come into contact with the discharged compressed air flow. Therefore, "no oil machine" is a relative term to the oil-injected screw compressor. Compared with the oil-lubricated air compressor, the oil mixed with compressed air in the oil-free machine is much less, and the oil injection volume of the oil-injected screw compressor may be as high as 1% of the machine volume displacement.
Compared with the traditional oil-injected screw air compressor, the "water-lubricated air compressor" is naturally oil-free. When there is no lubricating oil in the compression chamber, how can oil and gas be mixed into the compressed gas?
compressed air pollution source
from the point of view of the gas end, regardless of whether the user uses an oil-lubricated compressor or an oil-free machine, the source of compressed air pollution is the same. Therefore, the downstream system design considerations and air purification equipment requirements are the same. The difference is that the oil-lubricated compressor has a heavy pollution to the compressed air because of the large amount of contact between the oil and the air, and an additional set of lubricating oil separation and circulation system needs to be designed. In other words, whether it is an oil-free machine or an oil-free air compressor, the compressed air produced must be processed, especially for applications with high gas quality requirements.
Let us take a look at a set of ordinary oil-free air compressor compressed air pollution sources are what?
1) Atmospheric environment
we know that the working medium of the air compressor is air, and the source of the air is the ubiquitous atmosphere on the earth. However, the atmospheric environment is not spotless, which is mixed with a large number of dust particles, steam, oil molecules. When the air density is not high, it is not obvious. However, when the air is compressed, various impurities in it accumulate in the compressed air system to form harmful pollutants. Volatile organic compounds (VOCs), hydrocarbons, carbon monoxide and carbon dioxide, sulfur dioxide, nitrous oxide, organic particles, dust, dirt particles and other pollutants are all present in the atmosphere. In addition to organic matter, various microorganisms and bacteria are also prevalent, especially in medical, food and other high-quality compressed air applications. When brought into the air inlet of the air compressor, these elements can exist in the form of oil.
According to industry reports, according to the monitoring report of DEFRA from 2012 to 2015 by the British agency, the Ministry of Environment, Food and Rural Affairs, the oil vapor content in the British atmospheric environment is 0.05mg/m-0.5mg/m, which cannot reach the ISO standard Class2 to Class3 levels. These oil vapors mainly come from automobile exhaust emissions, chemical pollution and so on. The environment of some industrial clusters in China is worse than this, and the oil vapor content in the environment is higher.
In order to obtain "oil-free compressed air" as much as possible, it is recommended to use "water-lubricated oil-free air compressor". If you want to know, please contact us at 18964858538. contact Mr. Hu.
Enterprises in the purchase of air compressor, facing in the frequency conversion air compressor and power frequency air compressor two choose one situation, in the process also need to consider the air compressor is to choose no oil, oil, or micro oil, what is the difference between the three. Air compressor is a mechanical equipment that provides power for the production line, which can be used in various production industries such as textile, laser cutting, and medicine. Although many production industries need air compressors, different industries have different requirements for air compressors.
Lubrication of single screw oil-free machine promoters think that the advantages of the equipment, because I do not have too much experience in this area, announced to you, only for reference. 1. The water-lubricated air compressor uses pure water for lubrication and cooling, and the internal parts combination of the body is made of stainless steel. 2. The pure water of the water-lubricated air compressor system has been circulating in the system. The system will automatically change the water at a set time to ensure the quality of the water and the operating temperature of the body is not higher than 60 degrees, so the water is not in the body. Affected and scale problems.
Air compressor protection refers to some methods that can add the service life of the equipment, which is different from the regular maintenance, and the intention is also for the outstanding work of the whole system. Below, the technical staff will briefly introduce the following three methods
The first guarantee is usually 500 hours, that is, the first maintenance of the machine running-in. The first guarantee is relatively simple. It is good to replace the oil and filter. After the maintenance is generally about 2500-3000 hours, but also related to the air compressor site environment, if the site environment
As 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:

For those who don't know much about air compressors, choosing an air compressor is a very difficult thing. Many people want to know how to choose a suitable air compressor? Here I will introduce to you. For the selection of air compressor
When it comes to medicine, everyone should be familiar with it. However, most people are not very clear about the production process of drugs. Screw air compressors are often used in the production of drugs. So what role does the air compressor play in the pharmaceutical industry?
Shanghai Granklin Group produces water-lubricated air compressor series products, including water-lubricated permanent magnet variable frequency air compressor and water-lubricated power frequency air compressor. From 5.5KW-250KW models have production, you can call at any time to customize your needs. In the process of continuous gas consumption, the permanent magnet frequency conversion air compressor is actually not much different from the power frequency air compressor, so when the gas consumption reaches a certain value, the permanent magnet frequency conversion air compressor is used together with the power frequency air compressor, which can well reduce the energy consumption of the enterprise.
Air compressor, full name air compressor (English: air compressor) is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a pressure generator for compressed air. Is one of the most commonly used in industrial and mining enterprises to provide air power equipment. Usually, the air compressor is divided into screw type air compressor, piston type air compressor and so on.
