According to whether the air compressor needs the participation of lubricating oil at work, we divide it into two types: oil-free air compressor and oil-free air compressor. Therefore, many small partners have asked whether it is better to have an oil air compressor or an oil-free air compressor?
To get the answer to this question, we still have to compare the two in detail under the same standard. Today we compare the following convenience:
1. use of materials
first of all, the biggest difference between the two should be the difference in the use of materials. Oil air compressor is naturally its own material with oily substances, so called oil air compressor.
However, there is no oily substance on the material of the oil-free air compressor itself. In this way, the difference in raw materials has caused different results. Since the oil air compressor has oily substances, it will cause certain pollution to our terminal equipment during the working process. On the contrary, the oil-free air compressor will not.
2. working principle
secondly, the working principle of the two is also different. Oil-free air compressor in the working process is naturally no oil involved, mainly through the piston or screw rod to achieve compression. The oil air compressor can use the participation of oil to avoid the high temperature generated in the compression work and avoid danger.
3. exhaust gas
the oil air compressor contains a certain amount of lubricating oil, so the exhaust gas will also contain a certain amount of oil. The resin material used in the oil-free air compressor, so in the final exhaust gas does not contain oil components.
4. service life
the oil-free air compressor uses a heat-resistant piston. During the working process, the grease of the bearing will no longer be lost due to high temperature conduction, which effectively prolongs the service life of the air compressor.
However, there is no heat resistance piston in the oil air compressor, which makes the grease continue to lose during the work process, and the bearing will be damaged by friction due to lack of lubrication. However, the quality and service cycle of the oil air compressor are also guaranteed.
The specific choice of oil-free air compressor or oil-free air compressor, it is recommended that you combine the specific time requirements and follow the manufacturer's professional advice to choose.
Milk production enterprises do need to check the quality of compressed air, and there are strict requirements for the quality of compressed air. The reasons and specific requirements are as follows: 1. the key role of compressed air in milk production Compressed air is widely used in milk production, involving multiple key links:
Q: Water-lubricated oil-free air compressor and traditional air compressor which is more environmentally friendly? A: Water-lubricated oil-free air compressor is more environmentally friendly than traditional air compressor. The water-lubricated oil-free air compressor uses pure water as the lubricating medium, does not contain harmful substances, and does not pollute the environment. Same
When discussing whether the air compressor condensate can be directly discharged outdoors, we need to comprehensively consider environmental protection regulations, equipment characteristics, and various factors in actual operation. Taking the water-lubricated air compressor products produced by Shanghai Glanklin Group as the core, we can
Oil-free and oil-free air compressors are two different types of air compressors commonly used in the industrial field, each of which has its own characteristics and applicable scenarios. The following is the main difference between the two: 1. working principle has oil air compressor: this kind of air compressor in the compression process, oil
To get rid of the water in the air compressor, you can take the following methods: the use of cold and heat exchange technology: the newly generated hot compressed air pre-cooling treatment, which helps to reduce the moisture content in the air. Install the drain valve: in the storage of the air compressor
Deoiling and dehumidification of compressed air is the core link to ensure the precision of industrial production and the reliability of equipment operation, which needs to be realized by combining source control and post-processing technology. The following from the specification requirements, technical path and industry application of the three aspects of the system.
Air compressor nameplate is an important way to understand its parameters and models and other important information. Here are some ways to view and understand the nameplate of the air compressor: 1. the nameplate position The nameplate is usually located on the side, back or control panel of the air compressor. Before viewing the nameplate, you need to first
The air filter (air filter) replacement cycle of an air compressor depends on a number of factors, including the environment in which the air compressor is used, air quality, running time, and the quality of the filter. Generally speaking, the replacement cycle of air filter is recommended to be every 2000 to 4000 hours or according
Air compressor equipment attribute analysis As a basic equipment in the industrial field, the attribute positioning of air compressor needs to be comprehensively judged in combination with application scenarios and technical characteristics. The specific analysis is as follows: 1. General equipment attribute analysis Cross-industry application Air compressor is widely used
How about permanent magnet variable frequency air compressor -- take the water lubricated air compressor of Shanghai Greenland Group as an example to 1. the overview of permanent magnet variable frequency technology. Permanent magnet variable frequency technology is an important innovation in modern motor technology. Different from traditional
