Fan Balancing

Fan Balancing (Information used from GOST 31350-2007 “VIBRATION. INDUSTRIAL FANS. REQUIREMENTS FOR PRODUCED VIBRATION AND BALANCING QUALITY” — an interstate standard developed from ISO 14694:2003 “Industrial fans — Specifications for balance quality and vibration levels”) Source note: this page is based on the fan vibration and balance quality requirements equivalent to ISO 14694:2003 and related interstate (GOST) adoptions of ISO standards, whose designations differ from the original ISO publication numbers. Where older ISO 1940-1 terminology appears, the current balance quality standard is ISO 21940-11 (formerly ISO 1940-1). Vibration produced by the fan is one of its most important technical characteristics. Read more

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

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 unbalance, which should not exceed 0.1 g*mm/kg (µm). The requirement to include Read more

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

Industrial Centrifuge Balancing: Stop the Shake and Avoid Downtime How to Balance a Centrifuge: 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 Read more
