Displacement: Mils True Pk-Pk to Mils RMS?

Ali, (In regards to the 9 mils RMS) After reviewing ISO 20816-5:2018, I found that our pump's displacement alarms should fall within 270-310 micrometers pk-pk. This equals 10-12 mils pk-pk or 3.7-4.3 mils RMS. These values are within the contractor's recommended True pk-pk values. Therefore, the 9 mils RMS alarm we currently have is too high.

Top Six Pump Vibration Problems – Houston Dynamic Services

A pump with a bent shaft can cause high axial vibration with axial phase differences that tend towards 180° on the same rotor. A dominant vibration normally takes place at 1X RPM if the bend is near the shaft center. It can occur at 2X RPM if it is bent near the coupling. Bent pump shafts are more likely to happen at or near the coupling.

Vibration

Units are used worldwide but are in more frequent use outside the Western Hemisphere. Displacement is a distance, usually measured in mils ( 1 mil = 0.001") or in microns (1 micron = 1 millionth of a meter). Displacement is usually the preferred unit for low frequency vibrations of machines with running speeds of less than 1000 rpm.

How to Determine Root Cause of Excessive Pump Vibration

A margin of safety should be provided between the pump/vane pass speed/frequencies, and major structural (and/or pipe hydraulic) natural frequencies. Typical acceptable margins are 15-25%. The amplitude of the vibration response can be amplified 2.5 times or higher at or near a component natural (critical) resonant frequency.

Shaft Vibration

The result is that the peak-to-peak unfiltered (overall) shaft vibration is read in mils or thouh of an inch. The D.C. signal is normally calibrated for 200 mV per mil. Probe gaps (distance between probe and shaft) are typically 1 mm (0.040 mils) or 8 V D.C. to assure the calibration curve is in the linear range.

How to identify the cause of vibration in pumps

Generally, pump operators assume a cavitation issue, if the following signs occur: The noise level emitting from the pump is high The vibration in the pump is erratic with plenty of noise However, there are several reasons for flow-related troubles and excessive vibration in a pump. Cavitation is not always the culprit.

2 pumps make less noise than one, the primary reason is due to the restriction of flow in the loop. EVERY loop restricts flow, the greater the restriction, the noisier the pump. Speaking from experience, 2 pumps are quieter than a single pump, the easier it is for the pump to push water through the loop, the less vibration (and therefore noise ...

Basics of Vibration Measurement

Vibration is measured either in terms of displacement, velocity or acceleration. Vibration displacement is always measured as Peak to Peak, a measure of the total excursion of the rotor or machine casing in MILS or MICROMETERS. Vibration velocity and Acceleration are measured as Zero to Peak or RMS.
