Chengdu Roots Blower Factory introduces several reasons why Roots Blower cannot be started
What's the matter with the failure of Roots blower to start? Such machines and equipment as Roots blower are generally normal and no problem in normal operation. If you encounter the phenomenon of failure to start normally, what is the cause? The total area of bite teeth is too large.
Generally speaking, the normal tooth bite area of Roots blower centrifugal impeller is about 2/3. If the total tooth bite area is exceeded, it may lead to too much tooth bite force between transmission gears, resulting in common faults that centrifugal blower cannot rotate.
The corrosion condition is accompanied by the increase of the use time. If the maintenance of Roots blower is unreasonable or the water content of the transported material is too high, it is easy to cause the corrosion of the inner cavity of the centrifugal fan. In serious cases, the centrifugal impeller and the wallboard or shell rust together, or fall off on a large scale due to rust, resulting in a crash in the middle of the centrifugal impeller. At this time, measures such as gasoline pre-immersion and vehicle gasoline cleaning can be taken to solve the rust of the centrifugal fan, and then re-plan the gap.

Dirty things in the Roots blower operation, if the transport material with coarse particles into the inner cavity, very easy to block a part of the inner cavity, resulting in the fan can not rotate. At this time, we should eliminate the dirt in the cavity of the centrifugal fan, check the gap between the centrifugal impeller and the impeller, and also check where the dirt falls to avoid the recurrence of common faults.
Centrifugal impeller damage because of the destruction of the roots blower centrifugal impeller, so that the wind wheel and centrifugal impeller teeth bite each other and can not rotate, resulting in centrifugal fan can not rotate. In that case, we'll have to check it again.
Rolling bearing damage
When the rolling bearing of Roots blower is destroyed, it is easy to cause the change of the internal structure of the centrifugal fan and the friction of the centrifugal impeller. When it is obvious, the centrifugal fan cannot rotate. This is also the subjective factor causing the change of the gap of the centrifugal fan, which is the common reason that the centrifugal fan cannot rotate.
Deformation of parts
The main reason is that the quality of the purchased products is not up to standard. Some fan manufacturers blindly control the cost, resulting in substandard compressive strength of components. The price of the same model and specification is different. It is very likely that there are many problems such as too fine thickness of casting parts and motor shaft. In addition, the long-term placement of Roots blower machines and equipment will cause certain variations in parts.
Motor damage
When the motor of machinery and equipment that has not been used for a long time is abnormal, the centrifugal fan cannot rotate. At this time, we have to check the motor and then detect the fault.
Chengdu Roots Blower Factory: What Causes the Damage of Centrifugal Impeller of Roots Blower
1. Tired and damaged
Surface fatigue ground stress (or ambient temperature or impact) causes surface cracks and fish scales to fall off.
2. Abrasive wear
Due to the effect of the solid particles dispersed between the pages in the relative motion and damage, resulting in grooves and uneven contact area. It is very harmful to the damage level of the centrifugal impeller. In the three-leaf Roots blower, the solid particles and the surface of the parts move relatively at a lightning speed, causing damage.
3. Flushing damage
Solid particles clean the appearance of scratches on the surface of metal materials.
4. Suction damage
If other requirements are the same, the development of dimensional accuracy and surface cleanliness is not easy to reduce damage. On the other hand, due to the tightness of the page, the molecular structure has a large suction function, and the page is damaged. This is also the suction damage, the centrifugal impeller of the three-leaf Roots blower is damaged, and the machinery and equipment are tripping.
