Vacuum pump electric motor: bearing treatment reduced the current draw

Current draw fell on all three supply phases, on the untreated units it stayed unchanged. Vacuum pump electric motor, Brilyant AD. Bulgaria · 2004. 10.48 %.

↓10.48%

motor current draw, 28-30 → 25-27 A

on the untreated units the current did not change over the same 20 days

UNIT	CONDITION AT START OF PERIOD	WHAT WAS MEASURED
Vacuum pump electric motor, 22 kW, bearings treated	Phase currents 30 / 28 / 28 A	Current on the three supply phases at the start of the period and again after 20 days of operation
Units of the same plant left untreated — control group	Phase currents 30 / 28 / 28 A	The same over the same period; the protocol does not state the size of the group

Phase currents: treated motor and control group

PHASE	START OF PERIOD	AFTER 20 DAYS, TREATED	AFTER 20 DAYS, UNTREATED
I	30 A	27 A	30 A
II	28 A	25 A	28 A
III	28 A	25 A	28 A

Measurements were taken on equipment in service; the protocol does not name the instrument. The right-hand column covers the units that were not treated: their current did not change over the period.

Conclusion of the plant commission

The Brilyant AD protocol, signed by the head of the Power Engineering department and the plant power engineer, states verbatim: «the measurements taken show that consumption has fallen by 10.48 %, which in turn will lead to lower electricity costs and a longer bearing service life». The treatment was applied to the bearings of a running vacuum pump electric motor rated 22 kW, and the repeat measurement was made after 20 days of operation. The same table in the protocol contains a row for the units that were not treated: their current over the same period remained unchanged — 30 / 28 / 28 A across the three phases.

The results relate to a 22 kW vacuum pump electric motor at the Brilyant AD site in Sofia after 20 days of operation following bearing treatment; on other equipment and under other operating modes the figures may differ. The original protocol with signatures and seal is published in full and available for download.
