So my big shop compressor has two problems.
First, when it starts, it starts suddenly. Enough to startle whoever`s
in the shop, which is not just annoying but dangerous.
Second, when it starts, it`s now making a squeak sound for a moment as
well as the expected noises. I mean, a LOUD squeak, like it`s trying to
rip the pulleys off. (oil level is fine)
So I might as well address both problems at the same time.
The usual litany of questions follows...
Has anyone experienced a loud squeak at compressor startup? I assume
I`ll be disassembling the whole drive chain and inspecting everything,
but I might as well have something to look for.
Has anyone tried to soft-start a compressor? I`ve added hard-start kits
to motors before to avoid current spikes, but nothing designed to ramp
up the speed itself. Is switching to three phase and adding a VFD to
ramp up the speed overkill, or even possible?
