Low Speed and High Speed Rotors |
|
 |
Balancing is the process of attempting to improve the mass distribution of a rotor, so that it rotates in its bearings without uncompensated Couple (Moment) Unbalance may be found in a rotor whose diameter is less than 7 to 10 times its width. In the case of a cylinder, it is possible to have two equal masses placed symmetrically about the centre of gravity, but positioned at 180° from each other. The rotor is in static balance, i.e. there is no eccentricity of the centre of gravity, but when the rotor turns, the two masses cause a shift in the inertia axis, so that it is no longer aligned with the rotation axis, leading to strong vibrations in the bearings. The unbalance can only be corrected by taking vibration measurements with the rotor turning and adding correction masses in two planes. |

M.S. , S.S. , C.I. and Aluminum Impellers |
|
 |
Impellers are classified based on the number of points that the liquid can enter the impeller and also on the amount of webbing between the impeller blades. Impellers can be either single suction or double-suction. A single-suction impeller allows liquid to enter the center of the blades from only one direction. A double-suction impeller allows liquid to enter the center of the impeller blades from both sides simultaneously. The illustration below shows simplified diagrams of single and double-suction impellers. Impellers can be open, semi-open, or enclosed. The open impeller consists only of blades attached to a hub. The semi-open impeller is constructed with a circular plate (the web) attached to one side of the blades. |

Aluminum , C.I. Pulleys |
|
 |
There are three major factors that have guided engineers to balance pulleys: 1. improve pulley bearing life. 2. eliminate unacceptable belt vibration. 3. eliminate unacceptable structural oscillation. In most cases, only the third point is relevant, due to todays accuracy of manufacturing. Often pulleys revolve at .5 to 2 hz. This can be in the same domain of long span and cantilevered trusses. The latter more specifically has a very low natural first / fundamental modal frequency. When so, undesirable oscillation can cause excessive structural stresses, and can cause sympathic belt beat vibrations. |

Aluminum , C.I. Rollers |
|
 |
When operating at higher speeds, unbalanced rollers perform poorly. Unbalanced rolls can also damage machinery or bearings, shortening equipment lifespan. Poorly-balanced rolls can even result in damaged substrate materials, or cause vibrations that lead to problems in converting and laminating processes. But in today’s converting and material processing industries, tremendous importance has been placed on achieving very high linespeeds and top quality. To ensure smooth roller operation - even at high speeds - Menges offers a very effective two-plane dynamic and static balancing service. With specialized roll handling equipment and proprietary software, Menges engineers measure roll performance at designated speeds. |

M.S. / S.S Fans -- F.D. / I.D. Blowers and Fans |
|
 |
The Automatic Fan Balancing System is an innovative technology that is capable of making ultra-precise balance corrections. It is primarily used on fans that experience particulate build-up, high temperature deformation, corrosion, or any combination of the three. The system uses a non-contacting power transfer mechanism and there are no moving parts inside. A control system continuously monitors fan vibration levels using a velocity pickup mounted to the bearing cap. Customer defined high and low trip points are set. When vibration exceeds the pre-set high trip point, a balance cycle is started. Once the vibration level is brought back down to below the pre-set low trip point, the system returns to a monitoring mode. Most applications are in the following industries: Cement, Steel, Paper, Fiberglass, Waste Treatment, Chemical, and Power/Utility. |

Crankshafts |
|
 |
Since different rods and different pistons are different weights, it is impossible to make a crankshaft that is balanced "right out of the box" for any rod and piston combination. All crankshafts must be balanced to your specific rod and piston combination. The first step in understanding crankshaft balancing is to understand the purpose of the counterweights. The counterweights are designed to offset the weight of the rod and pistons. You have the weight of the crankshaft and the pistons and rods. At any point in the assembly's rotation, the sum of all of the forces are roughly equal to zero. |

Spindles |
|
 |
The consequences of running any rotating equipment in an unbalanced state are clear: increased vibration, noise, and structural stress, along with decreased product quality and life expectancy, just to name a few. To counter these adverse effects, rotating equipment must be properly balanced to precision levels. The common element at the core of balancing machines is a precision spindle assembly. The spindle is used to both hold the item to be balanced, while also simulating the rotational force the item will be subjected to in real world conditions. A highly accurate spindle provides more precise readings and adjustments, resulting in more precise equipment. |
