As a Switchboard or circuitbreaker manufacturer you face
demanding market requirements for increased product
durability, safety and lower production costs. We offer
reliable and cost-effective solutions for helping
manufacturers to improve performance and reduce overall
costs.
Miniature circuit breaker
Challenge 1: Loosening during transit
Nuts and bolts loosen during the mevement
caused by transit leading to faulty
switchgears.
Solution: Lock nuts and bolts securely
with LOCTITE 290
Pole assembly
Challenge 1: Vibrational loosening
Threaded assemblies loosen up due to the
vibration caused y regular operations.
Gaps between the nuts and bolts lead to
micro movement between the parts leading
to self-loosening over time
Challenge 2: Gas leakage
Gas-insulated high voltage switchgear
typically use an SF6 gas to minimize
arcing when the circuit breaker is
activated. Without proper sealing, it may
result in the leaking of this gas.
Solution: Provide a 100% seal with LOCTIE
5910
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.
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.
