Most industrial centrifugal pumps carry a significant capital equipment value. It is
important to extend their service lives and ensure that they run efficiently.
Proactive
maintenance can reduce the risk of breakdowns and increase pump reliability and
longevity.
Bearing Frame & Housing
Challenge 1: Oil Leaks from Threaded Assemblies
The gaps between threads of drain plugs, oiler nipples,
fittings etc. can lead to oil leaks due to constant
pressure
changes within the bearing housing. Not only do these
leaks
increase costs but also lead to the seizure of fittings
and
safety hazards.
Challenge 2: Bearing Spinout, Corrosion and Component
Damage
Bearings are prone to spinning either on their shafts or
within their housings, resulting in damage to these
parts
regardless of whether they have been pressed, shrunk or
slip
fitted in place. The gap that exists between a bearing
and
shaft is an area where rust can form and cause damage to
the
parts.
Challenge 1: Gasket Failure between Bearing Frame and
Frame
Adapter
Leaks from the frame connection can mean money lost in
oil
consumption and potential safety hazards. This happens
because pre-cut gaskets cannot tackle the gap between
flange
surfaces. Flange imperfections are potential leak paths
that
pre-cut gaskets cannot seal and they relax over time to
make
the gaps large enough for leaks to happen.
Challenge 2: Fastener Loosening and Corrosion to Frame
Adapter Mounting Bolts
Bolts are always under strain caused by torque,
vibration,
shock, thermal expansion and contraction. The gaps
between
the engaging nuts and bolts allow these external factors
to
challenge the clamp load.
Challenge: Corrosion and Seizure of Pump Casing Bolts
The severe pump environments of constant temperature,
pressure and humidity changes cause the pump casing
bolts to
corrode and seize. Seized casing bolts make pump
maintenance
difficult and create additional labor associated with
drilling and tapping the bolt hole.
Challenge: Leaks between the Stuffing Box and Casing
The use of cut gaskets has inherent problems. Neither
does it
occupy all flange irregularities, nor does it maintain
elasticity. This leads to creation of leak paths that
corrode and damage the flange surfaces.
Challenge: Misalignment and Damage Due to Coupling
Loosening
Couplings are held in place by a key and a set screw. If
the
set screw loosens, the coupling can begin to slide along
the
shaft and disengage, or it can begin to wallow out the
keyway.
Challenge: Misalignment Due to Loose Mounting Bolts
Vibration and possible impact shock can work to loosen
the
mounting bolts. Loose bolts result in a loss of clamp
load,
which allows the pump to lose its level and aligned
configuration.
Food and Beverage processing industry needs to comply with stringent regulations.
Challenges
such as loosening due to vibration, leakages and corrosion, threaten the everyday
performance of processing machinery.
LOCTITE products help to combat the above challenges and increase machine
reliability.
Equipment reliability and predictability are most important to keep a cement
plant running 24X7. Below are some solutions to commonly encountered
maintenance challenges across various departments of a Cement plant.
Maximizing productivity and preventing unplanned downtime are critical in the
Mining industry. Proactive maintenance can help protect mining assets in all
phases of operations and reduce common, redundant failures.
From the coke oven plant and sinter plants to the pickling plant and cold rolled
finishing line, reliable equipment is a must. Expensive downtime due to un-
scheduled maintenance can be avoided throughout the steel making process by
utilizing LOCTITE maintenance solutions.
Decanter centrifuges are important equipment in an Oil & Gas plant. The below
sections will help service engineers tackle service and repair challenges to keep
the downtime short and increase equipment longevity.
Thermal Power Plant
Thermal power plant equipment operates in very harsh environments. Proactive
maintenance can help maximize production, extend equipment life and prevent
unplanned plant downtime.
Electric motor is an integral equipment for plant machinery. LOCTITE solutions help
to improve performance and reduce costs by preventing minor issues such as
self-loosening of threaded assemblies which can lead to unplanned downtime.
Prevent Pump Breakdowns with Increased Threaded Fastener Reliability
Frequent pump breakdowns can increase downtime costs and reduce productivity. LOCTITE
threadlockers ensure pump reliability and longevity by filling all gaps between
engaging threads, preventing self-loosening.
Increasing Pump Service Life by Increasing Rotational Component
Relaibility
Industrial pump reliability highly depends on cylindrical components like shaft and
bearing. Proactive maintenance of these essential components can reduce the risk of
breakdowns, preventing downtime costs and increasing pump service life.
Proactive Maintenance of Gearbox to Maximize Productivity
A gearbox failure can lead to costly setback and affect overall plant operations.
LOCTITE threadlockers combat common challenges such as loosening, corrosion and
seizure of fasteners, ensuring high reliability.
Leakages in gearbox can lead to reduce equipment life and amount to expensive
downtime. LOCTITE gasketing compounds ensure 100% flange seal preventing expensive
leaks
