The reason why the Roots blower does not turn
Roots blower use in the case of turning does not appear, then what causes such a situation? Roots blower small editor to take you to understand.
1、Foreign body stuck
There are large particles of objects into the fan cavity, blocking the gap between the parts, resulting in the fan can not rotate. In this case, you need to clean up the foreign matter inside the cavity and check the clearance between the impellers. Also check the cause of the foreign matter falling into, to avoid the recurrence of the fault.
2. Impeller damage
Impeller damage fan jammed turn, this fault we can easily understand, impeller and impeller bite each other, resulting in impeller turn, this fault needs to be disassembled to check the casing.
3. Gear damage
Normal gear bite area in about 2/3, and greater than this bite area, the bite force between the gears is too large, resulting in the gears can not rotate, which in turn caused by the fan can not turn the situation.
4. Bearing damage
There are 4 bearings on top of the Roots fan. If the bearings are damaged, it will cause the gap between the impeller and the impeller, the casing, and the wall plate to change, and there will be friction of the impeller, which will cause the fan to fail to rotate, and this is the indirect cause of the change in the gap of the impeller, which is also the common cause of the impeller failing to rotate.
5. Rusty and stuck
Roots fan idle for a long time, will appear in the internal and external rust phenomenon, the impeller and the wall plate or casing embroidered together; or rust appeared a large area of shedding, the impeller between the impeller may be jammed. Such cases need to be cleaned of rust by means of kerosene soaking, gasoline flushing, etc., and clearance adjustments need to be made.
6. Deformation of parts
Parts deformation caused by the three-lobe Roots fan turn is rare, there is a small part of the manufacturer to reduce the cost of parts strength is not up to standard, the same model price is low Roots fan, there may be casting thickness is thin, journal thin, etc. If the parts strength is not up to standard there may be deformation of the parts, destroying the gap between the parts, resulting in the fan jammed to turn not. Another product placed for a long time, will also cause certain deformation of parts.
7. Motor damage
Idle for a long time of the three-leaf Roots fan, if there is a motor failure, it will naturally produce the situation of not turning, the fault is easy to judge, the motor can not rotate, the fan will not naturally rotate, if the motor is faulty, the motor of the fan should be inspected, and then discharged from the fault.
