It
is said that the horizontal vibration on the NDE side is high. Where should I
look?
Looking at the components of a rotating
machine, they can first be divided into the
driving part (driving part) side, the driven part (driven part) side, and the coupling (direct coupling, buffer type, belt,
etc.) that connects them. Another connection element may be a gearbox that requires an additional separate coupling.
Since each component is a machine that is all connected and rotates together,
the speed may be different, but vibration is transmitted between each other,
and if any connecting part is incorrect or misaligned, the entire machine
(equipment) is affected by vibration. Therefore, determining what the vibration
is like at a certain location is a very important appointment. Among these, DE and NDE are words that you must know and understand.

Compressors can be categorized by type into centrifugal,
reciprocating, diaphragm, and screw types. Among them, the most noisy and
structurally problematic type due to vibration is the reciprocating type.
However, even though the structure is small, the type that produces too much noise to
be operated without a soundproofing enclosure and has frequent vibration
problems regardless of high or low frequencies is the screw compressor. A screw-type
compressor appears to be a square box covered with an enclosure and connected
to pipes, but inside it is a type of compressor that is complex and vibrates,
consisting of many gears, bearings, and pipes. Let's summarize what causes
vibration that may occur in this screw compressor.
