The bearing body machine and the thrust bearing are made of brass, and the bushing is made of TSQ-A, which can avoid the accidental friction with the main shaft and burn out. Each radial bearing is supplied by two rows of small holes with a hole diameter of 0.35 mm; the thrust bearing adopts a ring-shaped air supply form of the air bag groove, and has 16 air supply holes of 0.35 mm.
The requirements for bearing gas are: (1) clean. (2) The pressure above 0.4 MPa can be maintained for a period of time after the intake valve is closed. The pipelines matched with the bearings of the machine should be subjected to strict cleaning and purging. The pipelines matched with the organization of the machine are equipped with a nickel sheet fine filter, which can effectively prevent the mechanical impurities of the card machine from entering the bearing interior.
Since the air bearing expander is lubricated with air, the rotor speed can reach 60,000 rpm, which greatly increases the cooling capacity and shortens the oxygen production time. At the same time, it is effective in preventing the contamination of the working medium and safely operating the equipment. of.
The air bearing turbo expander not only facilitates operation, reduces maintenance, but also prolongs the life cycle of the whole unit, shortens the oxygen production time, improves the oxygen production, saves a lot of energy, and saves the total value of the whole year. Ten thousand yuan.
