Industrial gearboxes play an important role in processing and manufacturing facilities.
Reliable operation over a long service life, with minimum maintenance, is a key
requirement. Proactive maintenance can minimize expensive downtime, enhance reliability
and dramatically cut costs.
Housing
Challenge: Damage and Corrosion in Housing due to Bearing
Spin
Bearing outer races are prone to spinning within their
housings, resulting in damage to the housing. This damage is
regardless of whether or not they have been pressed or
shrink fitted in place. Once the clearance increases, the
air gap leads to fretting corrosion, causing damage to the
parts.
Challenge 1: Gasket Failure Between Upper and Lower Housing
of a Split Gearbox
Oil leakage from failed gasket between upper and lower
housings of split case gearbox can increase risk of gearbox
running low on oil and increase overall oil consumption,
safety hazards and clean-up costs.
Challenge 2: Loosening and Corrosion of Housing and Cover
Fasteners
Cover fasteners can loosen when exposed to torque, vibration,
thermal expansion and shock loads. Once the fasteners become
loose, the preload on the gasket is lost and the gasket
fails. Additionally, cover fasteners can corrode and seize
making gearbox maintenance difficult and hence create
additional labour associated with drilling and tapping of
the fastener hole.
Pressure and temperature changes within the gearbox can lead
to leaks from threaded fittings such as oil drain plug, oil
inlet, housing ventilation, oil pump, oil filter, oil gauge,
coolant pump, pressure and temperature control unit and all
pipe work.
Bearings are prone to spinning on the shaft due to dynamic
load on the assembly which produces axial loads higher than
the original calculations. This bearing spin leads to damage
on both shaft and bearing which may necessitate component
replacement, causing unplanned downtime and scrap costs.
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
