Air compressors with oil and without oil are not absolutely good or bad. Their use occasions are different from those suitable for working conditions. If they are used for purging, mechanical processing, manufacturing and power use, it is OK to choose air compressors with oil and micro oil. However, oil-free air compressors must be used in some occasions, such as food, medicine, precision instruments and other industries. Oil-free air compressors are cleaner and more environmentally friendly than oil-free air compressors to some extent, but oil-free air compressors are more expensive than oil-free air compressors and have higher maintenance costs.
In addition to the price, oil-free air compressor and oil air compressor has the following differences:
1. The oil content is different. Generally, the oil content of the oil machine is larger, and the oil content of the oil machine is 0.01ppm, so this oil content is used to distinguish the air compressor with oil and without oil. There is also a full oil-free air compressor, which is lubricated by water, so the final discharge of gas does not contain oil, called a full oil-free air compressor.
2. The structure is different. Whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature will be generated during the operation. The participation of oil in the air compressor will take away the high temperature generated during the compression process of the air compressor, thereby Cooling the machinery. The oil-free air compressor uses water to lubricate the air compressor head, and the heat generated inside the air compressor head is taken away by the water, achieving isothermal compression.
In applications, industries with higher gas requirements are better to use oil-free air compressors.
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.
Screw air compressor is an indispensable gas equipment in the production process of modern enterprises. It is an important gas source for enterprise production. Its application range is wide. The main application industries include the following: 1. Power industry, instrumentation, ash removal, factory miscellaneous compressed air system, water
The outlet pressure of the compressed air is a dynamic and adjustable parameter, which depends on many factors, including the type of compressor, specifications, operating conditions and the specific needs of the user. The following are some detailed analysis of the compressed air outlet pressure: 1. outlet pressure
The gas source design of the factory must consider the gas volume, which is the key factor to ensure the stable operation of the production. The following is a detailed description of the core requirements of the gas source system, the risk of insufficient gas volume, the hidden dangers of excess gas volume and the optimization direction: 1. gas source system
Compressed air is widely used in the foundry industry, and its importance is self-evident. The following are several main application aspects of compressed air in casting: 1. Power source and pneumatic control Pneumatic equipment Power: Many pneumatic tools and equipment are involved in the casting process, such as gas
In view of the problem that there is water in the air pipe of the air compressor, the following measures can be taken to solve the problem: install or check the air-water separator: install the air-water separator at the outlet of the air compressor, which can effectively separate the moisture in the compressed air. If already
The types of air compressors can be classified from multiple dimensions. The following are some of the main classification methods and corresponding types: Classification by working principle: Volume type: Compress gas by changing the volume of the working chamber, including piston type and screw type (Such as twin screw
Permanent magnet variable frequency screw air compressor has significant advantages in energy saving efficiency and operation stability through technological innovation. Granklin air compressor adopts water-lubricated single screw technology, combined with permanent magnet frequency conversion control, to provide users with more efficient and reliable compressed air
When the air in the air compressor contains moisture, the following methods can be adopted to deal with it: 1. install a drain valve and install a drain valve at the bottom of the air compressor cooler: the bottom of the air compressor cooler is usually provided with a drain valve, which can be opened regularly,
The air blown out of the air compressor is all water, which may be caused by the following reasons: the moisture content in the air is large: when the air is compressed, it will become a supersaturated state, and the water in the air will separate out and become a liquid. The moisture content of compressed air and the humidity of the air
In the process of compressing air, because the air itself contains moisture (ie humidity), the moisture in the compressed air precipitates and becomes a liquid, resulting in a certain amount of moisture in the compressed air. The following is a detailed analysis of the water content in the air in the air compressor: 1.
