Literally, oil-free air compressors and oil-free air compressors are easy to distinguish. However, in terms of their power generation equipment and energy efficiency, they are completely different. What is the main difference?
What is the difference in energy efficiency between oil-free compressors and oil-air compressors?
From the oil content point of view, the oil and oil-free compressor generally refers to the amount of oil content of the gas discharged from the exhaust port of the compressor. Generally, the oil-free compressor has more oil content. Oil content, but less oil content, about 0.01ppm. Therefore, the oil content can be used to distinguish oil and oil-free air compressors. There is also a fully oil-free air compressor, which is not lubricated with oil but lubricated with resin materials, so the final discharge of gas without oil is called a fully oil-free air compressor.
From a structural point of view, there is no difference between oil-free air compressors and oil-free air compressors. However, from the working principle, there is a clear difference between the two.
The oil-free air compressor has no oil during operation. Whether it is an oil-free piston machine or an oil-free screw air compressor, a large amount of high temperature will be generated during operation. If there is oil in the oil-free air compressor, the high temperature generated during the compression process of the air compressor will be taken away, thereby cooling the machine.
The oil-free air compressor does not contain oil, and a large amount of high temperature may be generated during the compression process, which brings some trouble to the air compressor. In fact, the oil-free air compressor uses a special high temperature resistant material Teflon or molybdenum disulfide to replace the oil to solve the high temperature problem in the air compressor compression process, so as to achieve the purpose of oil-free compression.
To some extent, oil-free air compressors are cleaner and more environmentally friendly than oil-based air compressors. Therefore, hospitals, laboratories, schools and other institutions. Ideal for use with oil-free air compressors. These enterprises and institutions also prefer to use oil-free air compressors.
As an advanced compressed air equipment, water-lubricated oil-free air compressor has many advantages, especially in the products of Shanghai Granklin Group. The following are some advantages of describing water-lubricated oil-free air compressors: 1. Environmental protection and friendliness:
The air compressors commonly used in the factory mainly have the following types: Piston air compressor: simple structure, relatively cheap price, large pressure area, suitable for a variety of environments. But as an earlier type of air compressor, its speed compared to the new generation of air
Air compressor in the absence of cold dryer can be short-term operation, but long-term use will bring a series of problems, affecting equipment life, product quality and production safety. The following from the principle, impact and solution three aspects of a detailed analysis: 1. the role of the cold dryer
The advantages and disadvantages of the power frequency air compressor are as follows: Advantages: reliable and stable: the power frequency air compressor is an air compressor running at a fixed speed, and the working frequency is a fixed 50Hz. Its operation is stable, not affected by load changes, and can provide compressed air stably for a long time. Because
Generally, there is no fixed standard value for the flow rate of gas used in a factory, because it depends on many factors, including the size of the factory, the production process, the equipment requirements and the type of gas used. However, based on publicly available information, we can summarize the factory
Both power frequency compressors and inverter compressors are equipment used to compress air, and there are significant differences in many aspects. The following is a detailed comparison of these two compressors: 1. drive mode and working principle Power frequency compressor: Drive mode: use power frequency motor
Granklin Water Lubricated Screw Air Compressor Applicable Water Quality Description Granklin Water Lubricated Screw Air Compressor adopts the compression structure of single screw and star wheel meshing, and uses pure water as lubricating and sealing medium to realize oil-free compression. For users about softening
CNC lathes usually need to be equipped with air compressors. Air compressors play a vital role in the operation of CNC lathes, which are mainly reflected in the following aspects: 1. the role of air compressors in CNC lathes to drive pneumatic components: CNC lathes
Compressed air in the medical production workshop has multiple key functions, which are essential to ensure the quality of medical products and the efficiency of the production process. The following are the main uses of compressed air in the medical production workshop: Filling of pharmaceutical preparations: In the medical production workshop
There is water in the air compressor outlet pipe, which may be caused by a variety of reasons. In order to solve this problem, you can try the following methods: Regularly check the gas-water separator: The gas-water separator is an important part of the air compressor, it can separate the compressed air
