The issue of range hood vibration
Thread Content
The vibration of the smoke extractor remains stable at around 50, and its axis trajectory is elliptical. Today, the unit was operated at reduced capacity, resulting in a decrease in the inlet pressure and inlet temperature at the leak point. The vibration of the smoke extractor is very large; the axis trajectory shows an 8-shaped pattern, with the amplitude at 0.5 times the frequency increasing. Please, experts, help figure out what the cause is – could it be an increase in catalysts in the flue gas?
Range hood? Could you please tell me what it looks like? Thank you :)
The smoke engine refers to the flue gas turbine of the catalytic device
An 8-shaped axis trajectory indicates poor alignment; oil film vortexing should be considered at a factor of 0.5
