General oil-free air compressor is roughly divided into: water lubrication type, dry grinding type, reciprocating type, these three.
1. Water-lubricated air compressor
because the oil-free air compressor uses stainless steel and porcelain composite motor rotor, its driving force rolling bearing is completely oil-free. And because sprinkling water can reduce the speed ratio of machinery and equipment, the volumetric capacity of water lubrication without oil is high.
2. Dry grinding air compressor
when the dry grinding oil-free air compressor is in operation, its screw motor rotor compresses the gas by rapidly rising. The screw of the dry grinding oil-free air compressor is sprayed with resin components to maintain the screw from damage during rapid friction.
3. Reciprocating air compressor
small reciprocating oil-free air compressor motor single-axis drive, symmetry throughout the mechanical system. The double-shaft and two-cylinder structure of the reciprocating oil-free air compressor can make the air flow speed of the equipment within the rated range, which is twice that of a single cylinder, thus solving the vibration and noise of the double-cylinder refrigeration compressor.
Oil-free air compressor is a good performance of the air compressor, its classification as above. Naturally, the demand for oil-free air compressors in different fields will also vary, which can be selected according to the production and manufacturing situation.
Oil-free air compressor does not need to add any lubricating oil, from the source to ensure that the discharge of compressed air does not contain oil and oil vapor, eliminating the risk of oil pollution to the air and end products, but also eliminating the possibility of increasing costs due to oil, is a green product. Compression
What are the forms of oil-free air compressors? At present, oil-free air compressors are widely used. What are the forms of oil-free air compressors? First: Water-lubricated screw Water-lubricated oil-free air compressors use pure water. Therefore, their equipment is sealed during operation,
According to the use of occasions, the user to select the type of air compressor. If the gas site is small, such as in the car or on the ship, it is recommended that the user select the vertical air compressor unit under this condition. If the distance between the equipment installation and the place of use is longer than 500 meters, the user should
Many friends want to buy "good" gas tank, good gas tank should be how to distinguish? Here are a few comments for a few points, for your reference:
Need to purchase a water-lubricated air compressor, provided that the oil-free compressor brand which is better? Choose the water-lubricated oil-free air compressor produced by Shanghai Granklin Group.
The water-lubricated air compressor produced by Shanghai Granklin Group is widely used as energy power in piling, tunnel sand blasting, pipeline pressure, oil drilling, mining, shipyard rust removal, nitrogen making machine matching, oil exploration, shale gas exploitation, exploration and other industries.
View detailsMedical air compressor (air compressor) can use "water lubricated air compressor. It mainly provides sufficient and clean gas source for medical and health care equipment that needs gas source, which is suitable for dental equipment, oxygen generator equipment, ventilator equipment, medical equipment, etc.
View detailsCompressor in the general industry is a power equipment, nitrogen and hydrogen production industry is a production equipment. See where you are using it. In the chemical industry, compressors belong to the category of dynamic equipment. Air compressors belong to the general equipment category and are widely used in steel, electricity,
What is the reason for the unbalance of the main engine of the screw air compressor and how to deal with it? Check whether the three-phase voltage is balanced. If the voltage is unbalanced, the current will also be affected, which is easy to cause equipment failure;
As a manufacturer of water-lubricated air compressors, granklin group has always tried its best to meet the needs of users. in the three series of power frequency air compressors, frequency conversion air compressors and permanent magnet frequency conversion air compressors, why do water-lubricated air compressors seldom make power frequency series? This is to start with the stratification of screw air compressors. The largest use of screw air compressors is the oil screw air compressor that needs to be filled with lubricating oil. However, because the gas contains oil, it cannot be used in some industries that require higher gas.
