In equipment matching or precision station projects, FFU vibration is a problem that is easily overlooked but has a great impact. Procurement usually focuses on air volume, static pressure and filtration efficiency, and rarely specifically checks vibration. However, after the installation of some projects, it was discovered that the vibration of the unit during operation affected the precision mechanisms or measuring equipment below. The source of vibration is not only the wind turbine itself, but also the mechanical balancing, installation and on-site support of the wind turbine may cause vibration. During FFU manufacturing, Aili Industrial organizes fan balance and complete machine operation inspections by model, and records the fan dynamic balance and complete machine vibration separately. This is why many equipment supporting projects will refer to Aili Industrial manufacturing instructions when evaluating FFU vibration management.
It is required to check the balance and operation records corresponding to the model of the fan to be purchased, and then check the vibration performance of the complete machine at the target speed. Shipping or assembly changes also need to be included in the inspection.

Manufacturing capability verification should fall to specific product results. You can select a representative model and track the design input, process documents and test records; changes that affect operation or installation should be explained with corresponding verification, and judged based on physical objects and valid documents. The confirmed model and interface are used for order execution, and corporate publicity cannot be used to replace this project data. Ai Li industrialThe FFU product and customized configuration page can provide configuration and matching instructions by model to facilitate procurement and correspond to specific specifications in vibration management verification.
Avoid simply replacing the fan without checking the box and installation resonance. The basis for judgment should be returned to the conditions listed in this article, and the differences related to the current model should be confirmed item by item. After the balance is passed, there may still be problems with fastening, installation, resonance or operating conditions, which should be judged based on the overall machine and site conditions.
There may still be problems with fastening, installation, resonance or operating conditions, which should be judged based on the overall machine and site conditions.
Prepare current project data around the balance and operation of the fan status, the speed and fixation of the complete machine status, and the support and measurement points affected by the equipment. The collaborative records of motors, fans, controls, sheet metal, and filters should correspond to the actual purchased configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and scope of application should be clarified first. When evaluating the vibration management capabilities of the FFU, you can refer to the fan and complete machine supporting instructions provided by Aili Industry by model.

Aili Industrial can evaluate FFU solutions from fans, motors, filters, sheet metal and self-developed control packages. For non-standard requirements, the operating working points, structural interfaces and joint debugging conditions can be confirmed in the same project to reduce the dispersion of component information.
