Unbalance is created when a machine’s center of rotation differs from the center of gravity. This can happen due to product or particles adhering to the rotor, or an uneven change in the impeller weight distribution. Though this is a common cause of excessive vibration, sometimes, other issues mask as unbalance, which is when vibration analysis is necessary. In most cases, we can fix balance problems in place. Over time, unbalance deteriorates other mechanical elements, such as bearings, shafts and structures, magnifying the problem..
Maintaining the balance condition of your machinery provides:
- Less damage/wear to bearings, shafts, rotors
- Reduced energy costs
- Fewer machinery breakdowns/loss of production
- Efficient operation of machinery
- Extended bearing and equipment life
- Raynesford Balancing can provide our balancing services anytime, anywhere
On-Site Rotor Balancing
Dynamic on-site balancing is provided by an experienced vibration technician for in-place balancing requirements. If the equipment can be operated at speed and there is access to the balance correction planes on the rotor, we will perform single and multi-plane balancing on rigid and flexible rotors. We strive to provide you balancing with precision tolerances with a minimal amount of our service time and your down time and a quick return to service.
During balancing, very close attention is paid to other conditions which may be adversely affecting operation of the machinery. Any such conditions detected while rotor balancing are addressed and resolved at the appropriate time with respect to the balancing program. After balancing, rotor balance sensitivities are permanently recorded. All service is followed up with a written report detailing findings, corrections, recommendations, etc.
We have helped customers from diverse industries:
- HVAC Contractors
- Property Management
- Building Engineers
- Manufacturers (large & small)
- HVAC Manufacturers
- Television/Film Studios
- Restaurants/Food Production
We can identify:
- Looseness (in bearings, parts or structures)
- Critical Speeds
- Deteriorating Bearing Elements
- Vibration from adjacent equipment
Typical Trouble Areas:
- Cooling Towers
Unbalance is often the source of excess vibration in rotating equipment. Out-of-spec vibration will shorten the life of your bearings and fatigue other components. Dynamic balancing in the field can remove this potential damage.
This is one of the tools used in Root Cause Analysis, using the vibration signaure of your equipment to diagnose problems and recommend solutions.
Periodic Condition Monitoring
Vibration surveys show the current and future condition of your equipment to provide a heads-up for preventative maintenenace planning.
