To choose the best equipment for dynamic balancing we must consider our needs and the option that allows us to finish the job in the easiest and fastest way. First, it is important to consider the type of environment in which we are working. Balancing process can be performed in fixed machine or “in situ”.
Basic equipment that only display numeric values and even more advanced equipment that contain time-continuous graphs, FFT spectrum and more advanced functions are available in the market. When difference in price is minimal between them, the most convenient path is to invest in the balancing equipment that has more advanced features.
Fundamental features in a good balancing equipment
Precision in Dynamic Balancing:
Precision allows the job to be done faster and to comply with the required balancing quality grades, it also depends in the ease to record longer periods of time. Low rotational speed machines require longer recordings to perform a good read. Precision also relies heavily in resolution. A good resolution helps analyzing more easily the difference between two machines that have similar vibration.
Few are the balancing equipments that comply with the three most common norms:
• ISO-1940 (quality grade in Soft Bearing Suspension)
• ISO-10816 (sets Machine Classes)
• Residual Imbalance (in mm/kg)
Portability:
If you are looking for comfort and security, wireless equipment is available. The WiSER and the WiSER-Balance app provide together a complete wireless balancing solution. This wireless equipment is practical and versatile when working in small and dangerous environments.
Some features of these wireless equipments are:
• Require less maintenance.
• Shock, water and dust resistant.
• Compatible with mobile devices.
• Intuitive apps and software.
Functions:
The dynamic balancing calculator is very useful tool in balancing processing. Some features are:
• Calculate test weights.
• Calculate weights and angles for 1&2 planes.
• Combine masses and Split weights.
• Balancing tuning.
Compatibility:
Displaying data in both measurement units (Metric and Imperial) is a key feature every dynamic balancing equipment must have. In addition, angle measurement configurations are optimal for balancing adjustments.
There also exist balancing equipments which are compatible with different types of sensors, like accelerometers, velocimeters and proximity sensors.
A good feature is the ability to select the windowing, resolution and the units of frequency. This can be very useful when performing a pre-analysis.
Automatic report generation:
It is ideal to generate reports in easy-edition formats like Excel or Word. Therefore, it becomes easier to read and manipulate data like graphs or other important calculations.
Cost-Benefit and Technical Support:
The investment return time is an important factor when purchasing any type of equipment.
Besides the equipment price, it is important to consider some additional expenses. The maintenance, the license, and spare parts may result in a higher price than just buying the equipment.
Modular and upgradeable balancing equipment is recommended in order to avoid problems with spare parts and legacy software.
I invite you to check the latest technologies available before purchasing a balancing equipment. What is better than having a personal demonstration of the equipment performing an analysis to focus at best your decision.
