Reciprocating compressor alignment
Thread Content
Our company uses a laser alignment device during the alignment of reciprocating compressors. The corresponding data obtained are as follows, but we’re not sure how to fill in the alignment table in the handover documents. Could you please advise us?
Isn’t the first one an axial displacement? Isn’t the second one a radial displacement?
This doesn’t match. What should be displayed by the laser is the value calculated after measurement. For example, if your motor is 4 units higher, and when viewed from the motor side it is offset 1 unit to the left, these values are all calculated after measurement. Accordingly, (a3-a1)/2 = -4 and (a2-a4)/2 = -1. Generally, we just attach the data related to laser alignment at the end of this table; everyone understands this
Mm-hmm, but can the handover documents just be attached at the end as well? ? ?
Yes, that’s how we do it here, as long as the property owner agrees
A laser scan is all that’s needed to check the watch. It will take less than two minutes to get it done. But now, even what one desires is colored
