The technical standard that rotor of centrifugal type fanner overhauls
From;    Author:Stand originally
The technical standard that rotor of centrifugal type fanner overhauls is as follows:
1, impeller welding line reachs main shaft to answer flawless, blade and turntable should be not had fall off layer.
2, the locknut of impeller and main shaft should in good condition without become loose, undertake to impeller nondestructive flaw detection is mixed measure thick, turntable decreases small amount to should not exceed the 1/3 of former ply, blade decreases small amount not to exceed the 1/2 of former ply, hub secures riveting nailhead diameter or height decreases to not be more than 1/5.
3, examination rotor each place radial beats and end panel beats, does the standard see next tables 1? ? 1.
4, impeller and entrance cone all around clearance is 5~15mm.
5, impeller is not had corrode badly, wear away, the blemish such as blade blemish.
6, impeller has been assembled should have low speed static balance test.
Express 1, rotor each place radial beats and end panel beats.

Place name asks to be worth / radial of the predestined relationship outside Mm impeller beats radial of journal of ≤4 main shaft beats radial of annulus of ≤0.01 impeller mouth beats the predestined relationship outside impeller of ≤0.06 of deviation of linearity of ≤2.5 main shaft shoulder of axis of jumpy ≤6 of two side end panel stops jumpy ≤0.02 of the end panel that choose a side
