Vibration Analysis is one of many H&N Electric’s Predictive and Preventive Maintenance services designed to help our customers save time and money through early detection of mechanical problems. Our highly trained service technicians use Vibration Analysis to identify problems in rotating equipment before these problems create equipment failures.
Features
Excessive vibration (the pulsating motion that moves a
machine from its original place of rest) is often the first
sign of other less obvious problems. Since vibration cannot
be accurately measured by touch, a spectrum analyzer and
transducer are used to convert the mechanical vibration into
an electronic signal that can be measured and analyzed.
This electronic signal can measure the vibration frequency
(how fast the machine is moving) and the vibration
amplitude (how much the machine is moving). These
measurements enable our technicians to pinpoint the source
and severity of mechanical problems.
By determining the overall operating condition of rotating
equipment, Vibration Analysis can detect:
• unbalance
• misalignment
• looseness
• worn or broken gears
• loose or faulty bearings
This evaluation can determine whether the vibration could be minimized by increasing the mass, reducing the stiffness or adding to the damping characteristics of the vibrating system.
Benefits
Periodic Vibration Analysis can establish performance trends that enable you to better predict the onset of bearing or gear wear. The benefits of this service include:
• Reduction of production losses and unplanned downtime due to problems not identified early enough
• Reduced maintenance and repair costs
• Improved equipment maintainability and reliability
• Increased equipment life
• Increased Mean Time Between Failures
• Professional, comprehensive custom reports
• Increased productivity and profitability
As part of our Preventive Maintenance Services, we also offer our customers a Condition Monitoring Audit. This comprehensive audit includes a complete survey of your equipment and recommendations on which of our services would be most appropriate to help extend the machine life of your equipment.
Thermal Imaging is one of many H&N Electric’s Predictive and Preventive Maintenance services designed to help our customers save time and money through early detection of electrical and/or mechanical problems.
A detection procedure that converts invisible heat energy into a visible picture, Thermal Imaging can detect overheated parts in electrical distribution systems and energy losses in manufacturing processes.
A detection procedure that converts invisible heat energy into a visible picture, Thermal Imaging can detect overheated parts in electrical distribution systems and energy losses in manufacturing processes. Through expert analysis conducted by our highly trained Services technicians, thermal images can reveal defects or problems in electrical systems and mechanical equipment or in any process that uses or produces energy.
Benefits
• Reduction of production losses due to unplanned downtime
• Reduced maintenance and repair costs
• Increased equipment life
• Increased Mean Time Between Failures (MTBF)
• Professional, comprehensive custom reports
• Increased productivity and profitability
H&N Electric supports the National Fire Protection Association's recommendation that annual Infrared Thermography inspections be conducted on all electrical distribution equipment as part of your regular maintenance program.
Features
Because thermographic scans are performed while your equipment is in operation, there is no lost production or machine downtime. Advance notice of developing problems enables you to conduct the necessary adjustments or repairs before costly, catastrophic failures occur.
Considering the high cost of electrical and mechanical failures, Thermal Imaging can result in substantial savings.
• Early indication of electrical deterioration
• Bearing and coupling wear
• Insulation leaks
• Faulty electrical contacts or connections
• Leaky steam traps
• Refractory deterioration
• Excessive temperatures
• High resistance connections
• Unbalanced or overloaded circuits
• Improper grounding
• Inductive heating
• Open circuits
Increase Equipment Reliability, Extend Bearing Life and Reduce Power ConsumptionUsing the latest Laser Alignment
technology, our technicians at H&N Electric
can help you avoid inconvenient and
costly problems created by misalignment
of the shafts connecting two machines
(such as a motor and a pump).
When the centerlines of two connecting
shafts do not form a straight line under
normal operating conditions, the angular
misalignment can cause serious
mechanical problems such as:
Loose or worn bearings
Equipment that runs too hot
Equipment that doesn't rotate
properly
Excessive power consumption
A wide variety of production
problems and potential defects
Just one of many H&N Electrics Preventive Maintenance services designed to help our customers save time and money, our highly accurate Laser Alignments are performed through the use of laser transmitters and detectors that are mounted on each connecting shaft. If misalignment is detected, the front or back feet of one machine can be repositioned until the shafts are aligned within recommended tolerances.
Benefits
Too frequently, alignments are performed only
after problems surface. However, alignments should
be conducted routinely after any replacement of
motors, pumps or couplings if you wish to:
Increase equipment reliability
Extend bearing life
Reduce power consumption
Other benefits of regular and accurate Laser Alignment include:
Reduction of production losses and unplanned downtime due
to problems not identified early enough
Reduced maintenance and repair costs
Increased equipment life
Increased Mean Time Between Failures (MTBF)
Professional, comprehensive custom reports
Increased productivity and profitability
Dry Ice Cleaning is offered by your local H & N Electric Service Center. Also known as CO2 or Cryogenic Blasting, this type of process is a clean, safe alternative to conventional grit methods. Dry ice cleaning is for electric motors, generators, turbines, Anilox ink rolls, and any equipment or surface needing to remove the buildup of foreign material.
Features
Dry Ice Blasting is becoming a popular
method for on-site cleaning due to:
Little downtime as a result of cleaning equipment
in-place
Excellent results
No sand or soda to collect
Virtually no waste disposal
Benefits
Equipment removal and re-installation virtually
eliminated
Quicker and more thorough cleaning
Improved Resistance Readings
Elimination of Insulation Damage
Doesnt deposit abrasive foreign material into equipment
At H & N Electric we know AC MOTOR DRIVES and SOFT START MOTOR CONTROLS. All
our products and panels are assembled and
installed to exacting standards and are UL 508A
approved.
It takes experience and skill to match a drive to not just the motor, but the application. It may be practical to have the selection of a drive not based solely on that of a single source manufacturer. Our team knows and suggests what works best in a given situation.
H & N Electric seeks to provide a unique combination that simplifies processes, ensures connectivity and helps keep you competitive. For every drive and application requirement, as well as a full suite of industrial control drives, no one delivers more complete electrical control solutions and parts.
Features and Benefits
• Precision Speed Control
• Extended Motor & Equipment Life
• Typical Energy Savings of 10 to 50%
• Save Downtime
• Monitor Any Overload Condition
• Cease Operation for the Most Minor of Electrical Infractions
