What is the standard value of axial fan vibration?

General centrifugal / axial flow fan vibration judgment standard (JBTQ334-87) ≤5.0mm / s is good; ≤6.3mm / s is qualified.

Large-scale centrifugal / axial flow blower vibration judgment standard (JB / TQ433-85) ≤1.5mm / s good; ≤2.8mm / s allowed; ≤4.5mm / s bad.EC Axial Fans company

When the impeller rotates, the gas enters the impeller axially from the air inlet, is pushed by the blades on the impeller, and the energy of the gas is increased, and then flows into the guide vane. The guide vane changes the deflected air flow into axial flow, and at the same time introduces the gas into the diffuser tube, further converts the gas kinetic energy into pressure energy, and finally introduces it into the working pipeline.

Axial fan blades work similarly to the wings of an aircraft. However, the latter applies upward lift to the wing and supports the weight of the aircraft, while the axial fan fixes the position and moves the air.
