Therefore block and Reason
1、 The air-blower acutely shakes
① The air-blower shaft is against the electrical machinery shaft not not on an equal footing 、Transposition in pulley trough 。
② Envelope either moves forward tuyere together with vane wheel rub 。
③ The stiffness of base is insufficient either infirm 。
④ The vane wheel rivet becomes flexible either the shaft winds the deformation 。
⑤ The vane wheel shaft winds that Kong Yuzhou coordinates to become flexible 。
⑥ Envelope together with stand 、Bearing box together with stand 、The bearing box awaits that connectioing the bolt becomes flexible against the pedestal 。
⑦ Air-blower moves forward 、Export pipe laying is harmfully ，Coming into being flaps in all 。
⑧ The leaf blade stores up dust 、Filth 、Leaf blade wornout 、The vane wheel becomes deformed to cause the wheel disequilibrium 。
⑨ The upright refile of coupling stirs ，Piece is that the air-blower shaft is not concentric against the electrical machinery shaft ，Coupling is askew ，The coupling bolt becomes flexible 。
2、Bearing temperature rise overtops 。
①The wind cold dish bolt becomes flexible ，Cause since cools to be out of order either wind cold dish product dust 、The filth is very much much ；
②The bearing pedestal shakes intensely ；
③The grease quality is harmfully 、Deterioration 、Fill up too many 、Han's dust 、Impurity such as grit either filth and so on stick ；
④The bearing box tops 、The pedestal connections the taut force of bolt and passes through great either unduly a few minutes ；
⑤The shaft is fixed askewly against the roll bearing ，Two bearings are not concentric altogether 。
⑥Shaft is crooked 。
3、The electric motor electric current is passed through greatly and temperature rise overtopping 。
①Move forward when driving 、Vening the anger , the piping sluice gate does not shut 。
②The rate of flow overtakees that the stipulation is worth either the wind runs leaks gas 。
③Air-blower supply gas thickness is passed through greatly either the temperature is low unduly ，Cause pressure great unduly 。
④Main shaft rotation speed overtakees the nominal value 。
⑤Electrical machinery import tension is passed through lowly either the power source single phase stops providing electricity 。
⑥The coupling not connections ，The gum tightly either does not divede evenly in the gap has encircled 。
⑦Accept the bearing pedestal to shake the intense effect 。
4、The gummed type is slipd secondly ：
Two triangles are brought the trough to in turn the place not to be living one another on the centre line 。
5、The gummed type relaxs very much :
Gummed type wornout ，Lengthen ，Cause the gummed type relax . very much ，Two triangles bring iing turn the heart distance against the gummed type to develop not to suit ，Electrical machinery which ought to be regulateed on the smooth track of electrical machinery together with main shaft distance 。
Form a complete set of the supply limit
The air-blower is 1 ，Regulate one suit of door ，Form a complete system by one in electrical machinery ，1 pair on smooth track in the electrical machinery ，1 of pulley in the electrical machinery ，Triangle 1 pair on gummed type 。
