Sometimes motors in service don’t replicate controlled lab conditions. Load types may be mismatched or there might be operating efficiencies like worm gearing, wear friction or bad power, which could lead to an outage. CMT can test your motors to make sure they are up and running and repair as needed.
Keep your machines and processes running smoothly with preventative maintenance. CMT has a fleet of vehicles equipped with the tools to maintain your machines and, if necessary, repair them onsite, so your company doesn’t have downtime. CMT’s preventative and field services include: vibration analysis, dynamic balance, laser alignment, thermography, FARO measurement and PdMA.
All industrial and commercial process lines have machinery that can have a mechanical failure, such as an electric motor, gearbox, ventilation system, pump system or conveyor. Machinery downtime means work stoppages, which could be critical if on a production line. CMT can fabricate and machine new structural components, manufacture or repair small components and offers […]
Industrial air handling units serve many purposes: fume removal, dust collection, cooling air and material movement. Primary designs of air handling units include: vane axial design and centrifugal design. Vane axial design uses a propeller blade that draws air in and out of a tube in the same direction. Centrifugal design uses a blower wheel […]
Industrial crane brakes are found on all large overhead cranes. These industrial crane brakes are designed to stop and hold loads through several hundred tons. Industrial crane brakes have a fail-safe device that automatically locks when power is disconnected. It is located in the power transmission components to ensure safety in the event of a […]
A disassembly evaluation at CMT indicated the rolling element bearing failed because of service conditions. The DC roll motor and gearbox needed new shafts, bearings and gears because of improper alignment. Alignment is important in double shaft extensions. If one or both sides aren’t aligned, bearings are destroyed and shafts can twist. In addition to […]
Babbitt bearings are used in critical industrial applications like turbines, large motors, fans and blowers. They can be found in power plants, on military ships and in all industrial manufacturing facilities. Babbitt bearing failure often occurs because of maintenance issues: Lubrication deficiencies, contamination, mechanical alignment or vibration issues. With monitoring and proper lubrication, Babbitt bearings […]
Journal bearings are a housing shell or metal sleeve that allows a shaft to rotate freely inside while the assembly is structurally supported. Numerous journal bearing applications exist: Journal bearings can be used in low-speed operations (5 rpm or less) in a grease lubricated brass sleeve. Pictured is an oil ring lubricated Babbitt bearing in […]
Vacuum pressure impregnation, known as VPI, is a varnish process for electric motor insulation. The several-hour process begins with a prebake cycle to remove any moisture, the component is placed into the varnish chamber, a vacuum is pulled to remove air, varnish is introduced and the varnish chamber is pressurized. Computerized capacitance monitoring insures a […]
Is it balance or vibration issues? Balance is the uneven distribution of weight. Vibration is shaking driven by oscillation and disturbed equilibrium. Industrial preventive maintenance is critical to operations. CMT technicians can tell if it’s balance or vibration issues or something else to keep things running smoothly. Industrial rotating equipment can be several thousand horsepower […]
