We have an induced fan too! So our critical condition is aligning ID Fan,because of its high thermal expansion growth! I send an email to manufacturer and check for possible procedure . If there was no procedure I ask for thermal growth expansion analysis. Do you agree?
I have a forced fan that has two equipment as driver, a electric motor (start-up) and a steam turbine (permanent). I want to know which equipment is better to set as stationary for shaft aligning? What is the best procedure? For example set fan as stationary and align turbine and motor based on it?
