Manufacturers who need compressors often cannot tell the difference between oil-free screw air compressors and oil-free scroll air compressors. In fact, there are many similarities and differences between screw machine and scroll machine. The following granklin water lubricated air compressor manufacturers compare and distinguish through working principle, detailed comparison data, advantages and application scenarios.
1. Working principle
the scroll air compressor is a movable scroll that rotates around the center of the base circle of the fixed scroll, and the two mesh with each other to realize the process of suction, compression and exhaust. (as shown below)
the screw air compressor compresses the air by means of the volume change of the tooth grooves of the male and female rotors meshing in parallel with each other in the casing to achieve the purpose of compressing the air. (as shown below)
2. Application comparison
screw air compressor is widely used in machinery, metallurgy, electronic power, chemical industry, mining, textile, transportation and many other industrial fields.
Now the water-lubricated air compressor produced by granklin Group is also widely used in hospitals, pharmaceuticals, food, beverages, wineries, laboratories and other scenarios. granklin has solved a series of air compression problems on single screw air compressors.
scroll machine is mainly used in hospitals, pharmaceuticals, food, beverages, wineries, laboratories and other places with high noise and vibration requirements, which is directly related to the characteristics of scroll machine silence and compressed air oil-free.
According to the above principle, the oil-free scroll air compressor is characterized by no metal friction in the compression chamber, low noise and long life of the compressor. However, it is obvious that the oil-free scroll air compressor has high machining accuracy and high production technology requirements.
From the above technical comparison, it can be seen that the water-lubricated air compressor produced by Granklin Group has better effect, oil-free air compression is more stable, and the maintenance of the whole machine is more convenient.
Air compressors are used in electroplating plants: 1. Sand blowing before plating 2. Air blowing after plating 3. Products are used to spray varnish after plating 4. Some small tanks are also used for compressed air stirring. What equipment is needed to establish an electroplating plant
Q: What is the difference between a cold dryer and a suction dryer? A: The working mode of a cold dryer is different from that of a suction dryer. The cold dryer condenses the moisture in the air by lowering the air temperature to obtain dry compressed air.
What brand of air compressor is good? There are countless air compressor brands in the national market, and oil-free air compressor is currently in such a wide range of air compressor manufacturers. Can be 100% oil-free air compressor manufacturers, only a few leading brands. The water-lubricated air compressor produced by Shanghai Granklin Group is one of them.
View details1. The possibility of the screw air compressor failing to start the air compressor failing to start causes this problem is much more likely than price, but experienced engineers generally consider the problem from the following aspects: First, whether the fuse is burned out, this is a common question.
The main functions of air compressors in the food industry are embodied in the following two aspects: (Granklin water-lubricated air compressors, food factories use 100% oil-free) 1. Avoid contamination of equipment and food. Because food production often depends on natural fruits, the shelf life of these fruits is very short, which has strict requirements on the air environment of food production equipment and products.
The textile industry's requirements for compressed air are not only the oil content in the air, but also water and impurities. However, in these three items, the oil is more difficult to completely filter, so the quality of the gas used can be said to determine the grade of a textile enterprise. So how do you want to buy oil-free air compressors in the textile industry?
View detailsNow many enterprises with high gas quality will choose oil-free screw air compressor. Therefore, the quality of oil-free screw air compressor is more important for screw air compressor. However, there are many factors that affect the quality of compressed air, not only the air compressor itself, but also the poor environment and improper operation may lead to the decline of compressed air quality and fail to meet the production requirements. Therefore, if you want to make your oil-free screw air compressor continuously produce high-quality compressed air for you, then you must ensure that you give him a good working environment. So what are the requirements for the use of oil-free screw air compressor to the environment?
As the country pays more and more attention to energy conservation and emission reduction (fashionable name is carbon neutral), the application of low-pressure screw air compressor is also increasing. At present, there are three main types of low-pressure screw machines: dry screw, water spray screw, and oil spray screw.
On the whole, it is more cost-effective to purchase water-lubricated air compressors. After all, water-lubricated air compressors are better than traditional oil-injected air compressors in terms of maintenance and gas.
The solution to the water in the air of the air compressor is as follows: 1. There is a drain valve at the bottom of the air compressor cooler. As long as the drain valve is opened immediately, the water inside can be drained clean. 2. You can also install a drain valve at the lowest end of the air compressor storage tank, or
