Fan Balancing

Fan Balancing (Information used from ISO 31350-2007 VIBRATION. INDUSTRIAL FANS. REQUIREMENTS FOR PRODUCED VIBRATION AND BALANCING QUALITY) Vibration produced by the fan is one of its most important technical characteristics. It indicates the quality of design and manufacture of the product. Increased vibration may indicate improper installation of the fan, deterioration of its technical condition, etc. For this reason, fan vibration is usually measured during acceptance tests, during installation before commissioning, as well as when performing a machine condition monitoring program. Fan vibration data is also used in the design of its support and connected systems (ducts). Vibration measurements are Read more

Two Remarks on the Reasonableness of Customer Requirements for Balancing Machine Manufacturers

Introduction Over the past one and a half years, our company has received more than 30 inquiries regarding the purchase of various types of balancing machines. An analysis of the Technical Specifications attached to these inquiries reveals that most include a number of characteristics that significantly impact the production timelines and costs of the machines and also minimize the list of potential suppliers. Among these, two requirements stand out: The requirement to ensure a specific residual imbalance, which should not exceed 0.1 g*mm/kg (µm). The requirement to include the balancing machine in the Register of Measuring Instruments. Let’s analyze the Read more

Prevention is better than cure: How regular centrifuge balancing helps avoid costly breakdowns

Industrial Centrifuge Balancing: Stop the Shake and Avoid Downtime Industrial Centrifuge Balancing: Stop the Shake and Avoid Downtime Problem: An industrial centrifuge in a home textile factory (used for washing and drying pillows) was shaking violently, rattling the entire floor. Not only did the noise alarm the staff, but the vibration was putting extra stress on the machine’s bearings and structure. This scenario is common in many plants: an out-of-balance centrifuge can quietly drain maintenance budgets and lead to unexpected failures. Even a small imbalance can have a huge impact. At around 3000 RPM, a tiny 10 gram off-center mass Read more
