The difference between oil-free air compressor and oil-free air compressor
from the oil content point of view, the oil and no oil in the air compressor generally refers to the amount of oil content in the exhaust gas 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, so the 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 resin material lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.
From a structural point of view, there is no difference between the bearings of oil-free air compressor and oil-free air compressor. But from the working principle, there are obvious differences between the two. Oil-free air compressor in the process of operation is not involved in the oil, whether it is oil-free piston machine or oil-free screw machine, they will produce a lot of high temperature in the process of operation, if there is oil air compressor oil participation will take away the high temperature generated in the process of air compressor compression, so as to cool the machinery.
But the oil-free air compressor does not have the participation of oil, and in the compression process also produces a lot of high temperature, how to solve the high temperature to ensure the normal operation of the machine? In fact, the oil-free air compressor uses a special high temperature resistant material called Teflon or molybdenum disulfide, which replaces the oil to solve the high temperature in the compression process of the air compressor, thus achieving the purpose of oil-free compression.
Oil-free air compressor is cleaner and more environmentally friendly than oil-free air compressor to some extent, so institutions such as hospitals, laboratories, schools and other institutions are very suitable for the use of oil-free air compressor, and these institutions also prefer to use oil-free air compressor.
Which is better for air compressor with oil or without oil
good or bad depends on the occasion of use and the actual working conditions. In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor. But the oil-free air compressor is much more expensive and the maintenance cost is higher.
If it is used for purging, machining, manufacturing and power use, it is possible to choose an air compressor with oil and micro oil. Such as spraying, steel, electricity, hardware, mining, ceramics, textiles, machinery, etc. are widely used.
The head of the oil-free air compressor is cooled by lubricating oil. The compressed air discharged from the air compressor has a large oil content, but the oil content can be controlled within a certain range through filters and cold dryers, and the procurement cost is low. The gas demand of most factories; the oil-free head is not cooled by engine oil, with low oil content and high procurement cost. It is generally used in special industries, such as hospitals, pharmaceuticals, food processing, semiconductor industries, etc.
Many friends want to buy "good" gas tank, good gas tank should be how to distinguish? Here are a few comments for a few points, for your reference:
Manufacturers who need compressors often cannot tell the difference between oil-free screw air compressors and oil-free scroll air compressors. In fact, there are many similarities and differences between screw machine and scroll machine. The following granklin water lubricated air compressor manufacturers compare and distinguish through working principle, detailed comparison data, advantages and application scenarios.
View detailsMany people see this problem will think, oil-free air compressor is certainly not oil, oil compressor is oil. But in fact, this statement is not rigorous. Today, I 'd like to introduce it to you in detail.
With the rapid development of Internet technology, it is becoming more and more convenient to purchase oil-free screw air compressors. Just search the Internet "air compressor" a lot of information related to it will be displayed in front of everyone, so how to in this a lot of letters
What oil is added to the air compressor needs to be determined according to the type of air compressor. Small piston air compressor generally use ordinary mechanical oil can, viscosity is not too high on the line. If it is a screw air compressor or sliding vane air compressor, it is necessary to use special lubricating oil. Air compressor oil mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Its type is roughly divided into three types: synthetic oil, semi-synthetic, mineral oil;
Granklin air compressors are widely used in different industries, including electronics, electric power, hydropower, environmental protection, petroleum, chemical industry, mining, metallurgy, pharmaceutical, food, aviation, shipbuilding, scientific research, wood industry, textile, printing, glass,
Air compressor is an indispensable machine in production and life, and its existence provides great convenience for people's life. But so common equipment, there are still a lot of people do not know the role and use of air compressor in the end what?
Air compressor often have some quality accidents, resulting in great economic losses and security risks. However, to sum up the reasons, it is not the quality problem of the air compressor itself, but the negligence of the maintenance of the air compressor in winter.
When cutting stainless steel, the laser cutting air compressor should be equipped with a laser with higher power, and it is better to have more than 1000W if there is no burr at 3mm. The air compressor can use Grantklin Group's oil-free integrated laser cutting air compressor. The miniaturized screw air compressor is very easy to use.
When the single screw is running, the screw and the star wheel have a speed difference, one-way compression, air is easy to compress, and the speed is low. The twin-screw is co-extrusion, which requires high speed, and the lubrication of water is not enough compared to the oil density, and the compressed air is easy to flow backwards. The lubrication part is water, pure water. Air contains absolutely no oil, but it contains water. In the field of high gas quality requirements, such as textile, metallurgy, food, chemical industry, petroleum and air separation and other places that need pure oil-free compressed air, oil-free screw compressor can provide high-quality compressed gas to meet various needs, so the application prospect is broad.
