Reasons for collisions with Roots blowers
Roots BlowerIn the use of the process of collision, so what are the reasons that lead to the collision of the Roots blower? Roots blower small editor to take you to understand.
1. The shaft is not rigid enough.
Roots blower in the rotation, if the rigidity of the master and slave shaft is not enough to produce a torsional deformation (this deformation is within the limits of elasticity), and so that the two rotors or rotor and casing friction between. At this time, the shaft should be reprocessed to improve rigidity or replace the rigid shaft.
2. Gear wear.
Especially when the two rotors of the blower are placed horizontally, the position of the two rotors changes due to gear wear, resulting in friction between the two rotors. At this time, the gear should be overhauled or replaced with a new gear.
3. Gear keyway and key are loose.
Due to the keyway and key loosening, it will also make the two rotor position change, and make the rotor friction between. At this point, the key should be repaired or replaced with a new key so that it does not loosen.
4. Bearing clearance exceeds the specified technical requirements
Hard impurities in the gas being conveyed can cause friction between the rotors. In this case, the bearing clearance should be readjusted or the impurities in the gas should be removed.
