The main difference between the oil-free and micro-oil of the air compressor is in the lubrication mode, the use of the field and the maintenance.
Lubrication method:
oil-free air compressor in the process of compressed air, do not add lubricating oil or only add a very small amount of oil. It generally uses a variety of technologies such as fiber filtration, cooling, compression and drying to purify the air.
The micro-oil air compressor adopts a mixing method of lubricating oil and air, and the lubricating oil and air are separated by an oil-gas separator to realize the lubrication of the air.
Areas of use:
oil-free air compressors are widely used in industries that require high air purity, such as food, medicine, electronics, etc.
The micro-oil air compressor is suitable for industries with moderate air purity requirements and relatively low cost, such as agriculture, construction, etc.
Maintenance:
oil-free air compressor maintenance is relatively complex, the need for regular replacement of filters and desiccant.
The micro-oil air compressor is relatively simple and only requires regular inspection and replacement of the oil mist separator.
In addition, from the perspective of energy efficiency and life, oil-free air compressor also has its unique advantages. Since there is no lubricating oil, the operating cost of compressed air can be greatly reduced, and its average service life is relatively long. The micro-oil air compressor can reduce the wear and failure rate of the equipment due to the use of lubricating oil, thereby reducing the cost of maintenance and replacement of parts, and also extending the service life of the equipment.
In general, oil-free and micro-oil air compressors have their own characteristics and application areas. The choice of which type of air compressor needs to be determined according to the specific use requirements and environment.
When the air compressor has more water vapor, the following measures can be taken to solve this problem: regular cleaning of the drainage system: in order to prevent the failure of the drainage system, the drainage system needs to be cleaned regularly to ensure that it can effectively discharge the water vapor. Add or check dry
The shutdown sequence of the air compressor generally includes the following steps: Press the "Stop" button: First, you need to press the "Stop" button on the air compressor control panel. This button usually has a distinct logo to indicate stop
Domestic oil-free air compressor selection guide In industrial production, oil-free air compressors are more and more favored by users with their unique advantages, such as providing pure compressed air, reducing environmental pollution and maintenance costs. In many brands, how to choose a
In the foundry industry, air compressor has a wide range of uses, mainly reflected in the following aspects: 1. Pneumatic tools and equipment power tool support: foundry often use pneumatic hammer, pneumatic grinding wheel, pneumatic drill and other pneumatic tools, air compressor for these tools to provide the required gas
The replacement time of the air filter of the air compressor is actually an interesting problem that requires comprehensive consideration of many factors. Generally speaking, a good air compressor air filter can be used for about 1500 to 2000 hours under ideal conditions, and then it needs to be replaced with a new one.
Whether adsorption dryers and filters are special equipment depends on their specific design, manufacture and use conditions. In general, the adsorption dryer itself does not belong to special equipment. Adsorption dryer is a kind of adsorbent (such as activated alumina,
In the field of air compressors, "ppm" is an abbreviation of "parts per million", meaning "one part per million". When talking about the residual oil content of air compressor, ppm is used to quantify the oil content in compressed air.
The oil content standard of the micro-oil air compressor is: the oil content of the 1. outlet will also increase, and the oil content standard is the value measured under standard working conditions, and the use and operation The higher the temperature. Generally, the air outlet marked by each brand includes
The main difference between water-jet screws and oil-free screws is reflected in their cooling and lubrication methods. Cooling method: Water jet screw: This type of screw uses water to cool during compression. The water spray system can spray water mist to the screw
There are some differences in the design and working principle between screw air compressor and oil-free air compressor, which are mainly reflected in the lubrication mode, compressed air quality and application field. The following will be combined with Shanghai Granklin Group water lubrication oil-free frequency conversion screw
