Last layer self-lubricating material is applied at position, the technique for applying self-lubricating material is generally：Hard oxygen-cleaning-spraying-the burning of sandblasting-cleaning-
Knot.Its complex process and precision is relatively low.Although the oil-free turbo-compressor of this structure has achieved the purpose that oil-free, but rubbing
Wiping, service life and fever above there is a problem of new again.Another kind is on the basis of totally enclosed type screw compressor gas in compressor
The element that body stream passes through is separated with the element that needs lubricate, and this structure has equally achieved the purpose that clean gas, but not
It is the oil-free turbo-compressor in a just sincere justice, and the transportation oil of compressor is realized by pressure difference, is not being pressed
In the case of difference, needs in addition to provide power for oil circuit, there is the presence of oil just to will produce the consumption of the energy and the pollution of environment.
