Fu Sheng screw air compressor adopts Swedish SKF bearing, and the rotor is balanced by dynamic balancing machine, with good balance, small vibration and low noise.
High compression ratio
3. 1 Fu Sheng screw air compressor has the highest single-stage compression ratio in the world, and the highest single-stage compression ratio can reach 18, so the working pressure of Fu Sheng screw air compressor can reach 1.5MPa.
Low oil content
Oil-gas separation device is the most critical part of screw air compressor. Fu Sheng screw air compressor adopts German Mann products, with reliable technical indicators and oil content below 3ppm.
Screw air compressor has few wearing parts and long continuous running time.
Common wearing parts of this machine are: air filter element and oil filter element. This wearing part can be replaced regularly, or the corresponding parts can be replaced according to the LED lights on the computer panel.
SKF bearing is adopted, which has long service life and ensures the long-term continuous operation of the screw main engine ≥ 50,000 hours.
Institutional guarantee of high import rate and high product quality
In order to ensure the stability of product quality, Fu Sheng Company has adopted a large number of high-quality imported components. At present, the products are all imported components except range hoods, motors, high-voltage cabinets and oil-gas separation barrels.
Gas path system: The third-generation high-efficiency screw main engine, the oil-gas separation device of German Mann Company and the CKD pressure regulating valve imported from Japan are adopted to ensure the generation of high-quality compressed gas.
Oil system: The oil filter manufactured by German Mann Company can filter out impurities in lubricating oil, thus ensuring smooth, lubricating and heat dissipation of the oil system.
Cooling system: high-quality imported cooler is adopted, and the design premise is high temperature and high humidity environment. The design of low temperature difference is adopted, and the temperature of water rises by 6 ~ 8℃ to ensure that the outlet temperature of air compressor is less than = 40℃ (the temperature rise of water in domestic similar screw air compressors is generally around 13 ~ 15℃, and the outlet temperature of air compressor is at least around 45℃).
The design temperature of Fu Sheng screw air compressor is 46℃, while the domestic similar products are generally 38℃.
Electrical components: components imported from Japan and other countries are adopted to ensure reliable system control.
Other mechanical structures
The connection mode between the main engine and the motor is coupling connection. Its characteristics: the flexible connection between the main engine and the motor is reliable, which is convenient for oil filling and maintenance of the motor, and the single piece is light in weight and convenient for on-site maintenance. In China, the main engine of similar products is directly connected with the motor, so the bearing end of the motor shaft is not easy to be oiled, and it is difficult to maintain it on site when it fails.
① Perfect tooth profile: a patented product formed by effectively improving the tooth profile of the German GHH rotor by using the cylinder block of the third generation high-efficiency spiral engine. The main and auxiliary gears are changed from five teeth to six teeth, which improves the thermal efficiency by 10- 12% and saves electricity by 25% compared with the common screw type (four teeth are changed to six teeth) in China. This tooth type has been patented in Britain and the United States.
② Fully sealed shaft seal: completely sealed without oil leakage.
③ High efficiency rotor: After a long period of heat treatment and grinding, the rotor has lower leakage and higher efficiency than other models.
④ Bearings designed according to 100000 hours: special linear bearing support, which decomposes stress intensity and adds its own lubricating oil to avoid dry friction, thus prolonging the service life of shaft bearings.
Dustproof device
Considering the actual situation in China, the screw air compressor in Fu Sheng has added a dustproof net, which makes the main engine run more reliably, takes longer to replace the air filter and lubricating oil, and dissipates heat better.
At present, there are several major brands in the air compressor market: Atlas, Fu Sheng, Ingersoll Rand, Shouli and Borg.
