The performance of the Roots blower directly affects its working efficiency and quality, so the maintenance of the Roots blower must be taken seriously. Recently, customers have inquired about the vibration of the Roots blower being particularly large during operation, and this vibration exceeds the limit. How to solve this? Let's take a look at this explanation.
Roots blowerThe performance directly affects its work efficiency and quality, so the maintenance of the Roots blower must be taken seriously.
Recently, customers inquiredRoots blowerthat the vibration during operation is particularly large, and this vibration will exceed the limit. How to solve it? Let's take a look at this explanation.
The vibration limit of the Roots blower may be related to quality and long-term maintenance. The rated current of the selected automatic switch is less than the rated current of the motor. When the motor is running at full load, it cannot meet the technical requirements.
When the vibration exceeds the limit, the failure manifests as: loud fan noise, vibration speed exceeding 13mm/s, and a decrease in air volume and pressure. There are many reasons for the vibration to exceed the limit.
01 Loose anchor bolts or other fasteners
Omissions during installation and debugging, anchor bolts loosen again, and were not dealt with in time.
The Roots blower has no damping measures.
No support for mufflers, etc., and all external loads have been added to the Roots blower.
02 Gear damage
Overload operation or abnormal impact;
Insufficient lubricating oil or poor oil quality.
03 Fan bearing damage
Poor lubricating oil quality or insufficient oil supply.
Long-term overload operation, exceeding the rated service life. Bearing damage, impeller rotor running imbalance, fan vibration, low operating efficiency, and even being bitten.
04 Impeller rotor imbalance
The residual imbalance of the impeller during manufacturing is mainly due to the low precision of the rotor during dynamic balancing.
Imbalance of the rotor in use. On the one hand, this is due to uneven scaling of dust and other contaminants in the air on the impeller; on the other hand, it is caused by friction and corrosion with air and dust during operation, leading to local peeling of the impeller and loss of its original balance.
