Vibration Analysis of Motor Cp1b
Kochi Refinery, a unit of Bharat Petroleum Corporation Limited,
embarked its journey in 1966.Formerly known as Cochin Refineries
Limited originally established in collaboration with Phillips Petroleum
Corporation, USA and Duncan Brothers of Calcutta.
The capacity –
Refining capacity- 30000 tonnes of crude oil per day
It is an ISO 14001 Environmental management system (EMS) and
ISO 9001:2000 quality management system (QMS) and also ISO
17025(Testing method in quality control) certification from NABL.
The refinery has successfully implemented the Occupational Health
and Safety Management System(OHSAS) 18001:2007
Liquefied Petroleum Gas(LPG),naphtha,gasoline,kerosene,
AviationTurbine Fuel(ATF),Gas Oil ,Furnace Oil andAsphalt.
Specialty products for domestic market include
benzene,toluene,white spirit,poly Iso-butane and sulphur.
The BPCL installation at Irumpanam, to which the refinery is
connected by pipelines, is the major product distribution Centre of the
Petro net CCK is looking after this pipeline.
The refinery’s foray into direct marketing began since 1993 as with
aromatic products such as benzene and toluene.
The entry into the international petroleum business stream began with
its first parcel of Fuel Oil exported in January 2001.

Safety and health
The CP1B motor has generated severe noise.
There are various reasons which cause of decline of its
This study is focus on how to reduce the severe noise that affects
the performance of the motor.
The data which given below are the notifications provided to operators
to do the maintenance.
The motor vibration reading are taken at 4 different locations
a) Motor non drive end
b) Motor drive end
c) Pump drive end
d) Pump non drive end
Vibration Spectrum Analysis
The increase in vibration could be due to variety of problems like
unbalance, misalignment, bearing damage flow problem, electrical
And some analysis carried out is shown follows;
There were no peaks corresponding to 1X vibrations.This rule out
unbalance as the cause of vibration.
No peaks were present at the 2X position. Hence we could
ascertain the reason was not mechanical looseness.
Peaks were not observed in random turning speed like 3x, hence
misalignment was not the cause for the excessive vibrations.
While observing the vibration spectrum we found out harmonics
of non-synchronous peaks and sideband peaks appearing around
the rotating face frequency.
By analysis the progressive side band peaks on either side of high
amplitude peak we can say that this may be due to any damage of
Unwanted vibration caused due to defect in the bearings.
This was the reason for erratic vibration peak values which
This problem was rectified by replacing the faulty carbon
alloy steel ball bearing with stainless steel ball bearing which
has high corrosive resistant strength
The work carried out enabled us to have a detailed study of condition
monitoring of rotary equipment through vibration analysis.
The unwanted noise generated due to the aberration of the bearing
caused due to corrosion.
Eliminate the noise of the motor and hence prevent failure of the motor.
The machine life was extended.Thus with the condition monitoring the
condition of the machinery is known beforehand and its chances of
failure can be eliminated.
