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…

Portable balancer, vibration analyzer, and balancer machine Balanset-1A.

Over the course of more than 5 years, approximately thousand devices of the Balanset series have been produced. During this time, three versions of the device have been released, and a lot of work has been done to improve both the device itself and its software. We strive for continuous improvement! We respond to the requests of our customers by adding new features. Throughout the entire existence of our company, we have continued to adhere to our pricing policy and strive to keep prices as low as possible, constantly expanding the capabilities of our devices and improving their quality.

About the experience of balancing the cardan shaft directly on the motor grader.

Found an old correspondence between our lead specialist and one of our customers.Correspondence from ten years ago! Autor : Valery Davydovich Introduction I must admit that I was very surprised and pleased with the results of the letter written to us by Andrey Kobyakov, the driver of the motor grader. His letter even surprised me – a specialist with more than 35 years of experience in the field of vibrodiagnostics and balancing. And for a long time I worked in the defense industry and balanced more than 1500 different machines and mechanisms starting from ordinary fans and smoke pumps and Read more…

Extent of Usage in Stationary Measurement Systems Statistics on the consumption structure of balancing devices manufactured by Vibromera reveal that approximately 30% of these devices are purchased for stationary measurement and computational systems in balancing machines or stands. Softbearing Machine Design Essentials The design illustration indicates a mobile frame affixed to stationary stands using ribbon springs. Influenced by the centrifugal force generated by the rotor’s imbalance, the trolley can undergo horizontal oscillations relative to the stationary stand. These oscillations are measured with a vibration sensor. Using Balanset-1A as a measurement and computing system in balancing machines Key Features of Softbearing Read more…

Improving the Quality of Micro Fans Through Precision Balancing

Balancing Coolers for Medical Equipment Balancing a Batch of 100 Coolers In response to a request from a medical equipment manufacturer, we undertook the task of balancing a batch of 100 coolers. Our process demonstrated high precision and effectiveness, significantly reducing vibration levels. Building a Stand for Cooler Balancing To accomplish this task, we constructed a stand consisting of a lightweight platform suspended on steel strings. This minimized external influences and provided precise and stable conditions for balancing. Using Epoxy Compound for Balancing We used a fast-curing epoxy compound as the corrective mass, applying it to the microfan blades. The Read more…

Balancing the rotors of electric motors.

Balancing Electric Motor Rotors: Methodologies and Outcomes Introduction The functionality and longevity of electric motors are profoundly influenced by the balance of their rotors. Especially after repair interventions, these rotors may exhibit imbalances that can reduce the efficiency and lifespan of the motors. Enterprises that specialize in motor repair often encounter this challenge. This article aims to elucidate the methodology of using specialized balancing equipment and the consequent outcomes, ensuring effective motor performance. The Necessity of Balancing Equipment Rotor imbalances can lead to an array of problems, including increased wear, reduced efficiency, and even equipment failure in severe cases. Hence, Read more…

Cost-Effectiveness of Balanset Devices: Revolutionizing Rotor Balancing and Vibration Reduction

The balancing of rotors is a central issue in numerous industries, particularly those that manufacture and operate fans. While the need for precision and reliability is paramount, cost-effectiveness is also a significant consideration. The Balanset series of devices has emerged as a disruptive force in this context, offering a unique value proposition. This article elucidates the cost-effectiveness of the Balanset series in rotor balancing and vibration reduction, as of early 2023.
