In the post-processing equipment of the screw air compressor, there are mainly air storage tanks, dryers and filters. Dry compressed air can ensure the operation of air compressor air system and production process.
The role of the dryer is to eliminate the condensed water in the compressed air and ensure the discharge of dry and clean compressed air. After being equipped with a related dryer, the compressed air still contains water because of these five reasons.
First, the air humidity around the air compressor station is high. The air itself has humidity and contains a certain amount of moisture. When the air is compressed, due to the high temperature inside the compressor, the moisture directly evaporates to form water vapor, and then discharges the compressor with pressure. When the compressor is stopped, the temperature drops, which will cause water vapor. Form condensed water. Therefore, the working environment humidity of the air compressor should be low; or the condensed water should be discharged before starting the machine.
Second, the post-treatment drying equipment fails. The general drying and post-processing capacity of the cold dryer is the pressure dew point of 3 ℃. If the temperature of your work site is lower than 3 ℃, there will be water. At this time, it is recommended to configure the post-treatment drying equipment of the micro-heat suction dryer, and the pressure dew point can reach -20 ℃ without water.
Third, the configuration of the post-processing drying equipment capacity is not enough. Generally speaking, the post-drying treatment capacity configured by the manufacturer for the user is configured according to the average gas consumption. If your instantaneous gas consumption is large, it will cause insufficient capacity of the post-processing drying equipment and cause water in the gas.
Fourth, the gas tank itself has the function of water accumulation, which contains a lot of water is not discharged, forget to drain. Regularly open the drain valve under the gas tank to drain the water.
Fifth, there is a problem with the pipeline design. The design slope of the compressed air pipeline is not enough, and the pipeline condensate is not discharged in time, which will cause water.
With the growth of enterprises and the improvement of customer requirements, more and more factories will choose the latter between price and quality when purchasing air compressors. But there are also some factories in order to covet the temporary cheap, and choose cheap products, cheap can buy?
When the single screw is running, the screw and the star wheel have a speed difference, one-way compression, air is easy to compress, and the speed is low. The twin-screw is co-extrusion, which requires high speed, and the lubrication of water is not enough compared to the oil density, and the compressed air is easy to flow backwards. The lubrication part is water, pure water. Air contains absolutely no oil, but it contains water. In the field of high gas quality requirements, such as textile, metallurgy, food, chemical industry, petroleum and air separation and other places that need pure oil-free compressed air, oil-free screw compressor can provide high-quality compressed gas to meet various needs, so the application prospect is broad.
The semiconductor industry is undoubtedly an industry that needs to break through the technological blockade in the next 10 years. In the global semiconductor industry, the development of the domestic semiconductor industry is relatively late. In the process of gradually breaking through the technological blockade in various industries, semiconductor companies are also gradually expanding the scale of the industry. In the semiconductor industry, the "oil-free compressed air" of the "water-lubricated air compressor" It is an important role in development.
The water-lubricated oil-free 5.5 kW screw air compressor produced by Shanghai granklin Group is neither big nor small. Compared with high-power models, 5.5 kW air compressor is already mini. The size of the machine means that the internal structure needs reasonable distribution. When purchasing water-lubricated air compressors, small models will drink less, whether they are freight or accessories, etc. Therefore, some customers do not need to consider this freight when purchasing air compressor equipment. A small forklift truck can fork hundreds of kilograms of equipment.

The compressed air produced by the oil air compressor is with a small amount of oil, and it must be filtered, and it is still endless.
The reputation of "oil-free air compressor" depends on the users who have used it. When a brand reaches a certain user base, most people say that it is easy to use and the gas supply is stable, then this "oil-free air compressor manufacturer" must be a "oil-free air compressor enterprise" with good reputation and excellent product quality ".
The air filter element is replaced every 1000-1500 hours under normal conditions. For places where the environment is particularly harsh, such as mines, ceramic factories, cotton mills, etc., it is recommended to replace the air filter element every 500 hours. When cleaning or replacing the air filter element, the components must be matched one by one to prevent differences.
When you need "oil-free air compressor" to provide "oil-free air" for the production of enterprises, will fall into a difficult problem of choice, so many types and brands of "oil-free air compressor", pick the eye. We can look at the difference between "power frequency air compressor" and "frequency conversion air compressor" to decide how to choose and purchase. If you need "water lubricated air compressor" or "oil free air compressor" may wish to contact us "Shanghai granklin group".
The variable frequency air compressor adopts variable frequency speed regulation, the permanent magnet synchronous motor has good efficiency, high power factor, wide efficiency range, which can ensure extremely high operating efficiency and greatly improve the power saving rate in the entire speed regulation range. The permanent magnet synchronous motor (PMSM) runs with low noise. Air compressor frequency conversion
Granklin air compressor is suitable for laser cutting machine. Compared with traditional oil air compressor, water lubricated air compressor has higher gas purity. Laser cutting products are suitable for high-end industry processing, intelligent robots, etc. Water lubricated air compressor has high gas production and clean gas without oil.
