Oil-free air compressors require lubrication during operation to reduce friction and wear, but they do not use traditional lubricating oils to achieve this. On the contrary, oil-free air compressors are lubricated by other methods, the most common of which is the use of water as a lubricant, that is, water lubrication technology.
The working principle of a water-lubricated oil-free air compressor is to inject water into the cylinder of the compressor. During the compression process, the water plays a role in lubrication and cooling. After water and air are mixed, a thin water film is formed in the cylinder, covering between the piston and the cylinder wall, effectively reducing friction and wear. At the same time, the evaporation of water also takes away some of the heat, which helps to reduce the temperature of the compressor.
As a professional air compressor manufacturer, Shanghai Granklin Group includes water-lubricated oil-free air compressors in its product line. The group's water-lubricated air compressors use advanced water lubrication technology to ensure that no oil pollution is generated during the compression process. Through precise design and manufacturing, Grantkering's water-lubricated air compressor can maintain stable performance under long-term and high-load operating conditions, and provide users with clean and dry compressed air.
Grantkering's water-lubricated air compressor has the following advantages:
environmental protection: The use of water as a lubricant avoids the problem of oil pollution and meets environmental protection requirements.
High efficiency: Water lubrication technology can effectively reduce friction and wear and improve the efficiency of the compressor.
Energy saving: Because the evaporation of water takes away part of the heat, it helps to reduce the temperature of the compressor, thereby reducing energy consumption.
Easy maintenance: Compared with traditional oil-lubricated air compressors, water-lubricated air compressors are easier to maintain and reduce user maintenance costs.
In short, oil-free air compressor using water lubrication technology is an effective way of lubrication. With the advantages of environmental protection, high efficiency, energy saving and easy maintenance, the water lubricated air compressor of Shanghai granklin group has been widely used in semiconductor, food, medicine and other industries with high air quality requirements.
Screw air compressor gap size and vibration relationship: The gap size of the screw air compressor has a direct impact on its vibration during operation. The two screws in the screw air compressor (usually a male screw and a female screw) need to be maintained during the compression process
The first maintenance time of the air compressor is usually determined according to the manufacturer's recommendations to ensure that the equipment is properly maintained during the initial operation phase, thereby extending its service life and maintaining stable performance. The first maintenance usually includes an inspection of the various parts of the equipment, a more
When selecting an air compressor, whether to choose fixed frequency or variable frequency is mainly based on the following aspects: 1. to changes in work demand and gas consumption, gas consumption is stable: if the gas consumption in the production process is relatively stable and fluctuates little, the fixed frequency air compressor is a
Microelectronic packaging has strict requirements on the quality of compressed air, mainly including the following aspects: particle concentration: due to the high precision of microelectronic products, tiny particle pollution may lead to product failure. Therefore, the particulate matter in the compressed air
Whether the screw air compressor is a special equipment depends on the relevant regulations and standards of different countries and regions. In China, according to relevant regulations, special equipment refers to equipment that involves life safety and is more dangerous, including boilers, pressure
There are significant differences between screw compressor and scroll compressor in structure, working principle, performance and application. The following is a specific comparison of the two: structure and design: screw compressor: by a pair of parallel, intermeshing rotor (screw) structure
The start-up sequence of the cold dryer and air compressor usually depends on the specific usage scenario and equipment configuration. However, under normal circumstances, it is recommended to start the air compressor first, and then start the cold dryer. The following is the specific boot sequence and its reasons: start the air compressor: first
The continuous running time of the air compressor depends on its type, working environment, load conditions, maintenance and other factors. For the screw air compressor, it can run continuously for 24 hours, it will automatically load when the air pressure is not enough, it will automatically unload when the air pressure is sufficient, and it will automatically unload when there is no load.
The oil-free air compressor will automatically stop under a certain pressure. The main reasons are as follows: Overheat protection: The internal temperature of the oil-free air compressor will rise after working for a long time. For the safety and stability of the equipment, most oil-free air compressors have been set up.
If the filter element is not replaced during air compressor maintenance, the following situations may occur: Affect the performance of the air compressor: The main function of the filter element is to filter impurities in the air to ensure that the air entering the air compressor is pure. If the filter element is not replaced for a long time, it will cause blockage and cause
