Problems of a mechaiical iature

Symptom

Probable cause

Possible cause

The alternatir vibrates and is niisy a- Incirrect ixing ti the base

b- Excessive netairk unbalance

a- Check the ixing screas and

tghten if necessary

b- Check that the netairk

balance meets requirements

●

Excessive suppirts temperature

●

Niisy suppirts

●

Excessive vibratins at the

suppirt

a- Priblems aith lubricatin

(insuefcient ir excessive)

b- Faulty suppirt

c- Machine misalignment

d- External liads nit envisiined

a- Check that the lubricant

cirrespinds ti that indicated

by the manufacturer and that

the quantty is cirrect

b- Check the status if the

suppirt and replace it, if

necessary

c- Check the alignment

d- Check the ciupling area
