The Importance of Fan Balancing in Industrial Equipment Maintenance

Introduction Fan balancing is one of the most sought-after procedures in equipment maintenance. This is due to the high sensitivity of fans to imbalance; even the slightest deviation can lead to significant vibrations. Imbalance occurs when there is a misalignment between the geometric center of the shaft and the center of mass. The higher the fan’s rotational speed, the more precise the balancing needs to be. Causes and Consequences of Fan Imbalance The most common causes of fan imbalance include: Abrasive wear on fan blades Dirt accumulation on fan blades Loose assembly, misalignment of the impeller relative to the hub Read more…

Balancing Mulcher Rotors: Why and How?

Balancing Mulcher Rotors: Why and How? A mulcher is powerful equipment used for shredding vegetation, shrubs, and trees. The mulcher’s rotor, rotating at high speeds, is subjected to significant loads. Rotor imbalance can lead to severe vibrations, noise, and premature wear of the equipment. In this article, we will discuss why balancing the mulcher’s rotor is so important and how to perform it correctly using the portable balancing device Balanset-1A. Video: The Process of Balancing a Mulcher Rotor Detailed Overview of the Standard Balanset-1A Package Balanset-1A is a popular portable device for rotor balancing. The standard package includes: Control Unit Read more…

Centrifuge balancing. How to balance the rotor of an industrial washing machine.

This article takes you through our recent visit to a home textile factory where down pillows and blankets are manufactured. Our focus will be on the balancing process of the machinery involved in the production. Pre-Balancing Procedures: Vibrometer Mode Measurements Initial Step Before proceeding with the balancing, it is advisable to conduct measurements using the vibrometer mode. Identifying the Rotor Unbalance If the value of the total vibration is approximately equal to the value of the reverse component, it is likely that the primary cause of the machine’s vibration is an unbalance in the rotor. In this case, you can Read more…

Combine Rotor Balancing. Savings on Repairs and Maintenance.

1. Introduction Rotors of agricultural machinery (threshing drums of combines, straw choppers, rotary mowers, etc.) rotate at high speeds and carry significant mass. Even a slight imbalance in such rotors can cause strong vibrations, affecting the operation of the entire machine. Balancing rotors is a crucial part of servicing combines and mowers, which determines the reliability and efficiency of the equipment. However, in practice, this aspect often receives insufficient attention. As a result, unbalanced units lead to accelerated wear of parts, unexpected breakdowns in the peak season, and even pose a safety threat. This material examines in detail why rotor Read more…

Introduction to rotor balancing

Dynamic balancing devices for shafts and machine equipment Balanset-1A priced at €1751. The rotor is a body which rotates about some axis and is held by its bearing surfaces in the supports. The bearing surfaces of the rotor transmit loads to the supports via rolling or sliding bearings. The bearing surfaces are the surfaces of the trunnions or the surfaces that replace them. In a perfectly balanced rotor, its mass is distributed symmetrically about the axis of rotation, i.e., any element of the rotor can be matched with another element located symmetrically about the axis of rotation. In a balanced Read more…

Balancing the crusher at the Nestlé plant.

Elevated Vibration Levels in Nestle Pet Food Plant In June of last year, a contractor responsible for maintenance at a Nestle plant specializing in pet food production encountered an issue with one of the crushers. Post-maintenance, the machine displayed increased vibration levels, reaching up to 8-9 mm/s, well above the acceptable standards. The Consequences of High Vibration High vibration levels in machinery like crushers can lead to: Increased wear and tear Elevated energy consumption Possible safety hazards Disruption in production quality The Balancing Intervention To address this urgent issue, balancing procedures were performed on the affected crusher. The intervention involved: Read more…

Portable vibrometer balancer ArBalance.

During the balancing of the Fecon forestry mulcher with the FAE attachment, our specialist recorded short videos of the rotor balancing process. In this video, a portable balancing device, the ArBalance vibration analyzer, is used. The balancing process is similar to the process with the Balanset-1A device. The technical characteristics of the device are similar, and vibration sensors and a laser tachometer are suitable for both devices. If desired, the ArBalance can also be used as a measuring system for machines. Its main difference is that the ArBalance is completely autonomous and does not require connection to an external power Read more…

Modernization of an old balancing machine with hard-bearing supports.

Earlier in the article, I described the modernization of an old balancing machine with soft-bearing supports. For such machines, we install the Balanset-1A balancing device in the case of machines with two supports, and the Balanset-4 in the case of machines with more supports. In this article, we will consider the modernization of an old balancing machine with hard-bearing supports. Their supports are made in the form of rigid plates with shaped grooves (slots). The natural vibration frequencies of these supports are significantly (at least 2-3 times) higher than the maximum rotational speed of the rotor being balanced on the Read more…

Balancing stand with soft support.

The image shows a simple balancing stand being used to balance gears. The main feature of softbearing support balancing stands is that they have relatively compliant supports based on spring suspensions, spring-mounted carriages, flat or cylindrical spring supports, and so on. The natural frequency of oscillation of these supports is at least 2-3 times lower than the rotation frequency of the balanced rotor that is mounted on them. As shown in Figure, the movable frame (slider) 2 is attached to the fixed support posts 1 of the stand using a suspension system with ribbon springs 3. Under the influence Read more…
