How does the FFU tender require verifiable wind turbine operation data?

In FFU bidding documents, fan operating data often requires only two figures: 'air volume' and 'static pressure'. This way of writing makes it difficult to judge whether the data of various companies are comparable during review. The fan curve can help determine candidate operating points, but the actual FFU operation is affected by the inlet structure, internal flow equalization and filter element resistance. The maximum value of a single unit is not equal to the performance of the entire machine. The bidding documents should require the supplier to describe the fan model, speed, power supply conditions and test boundaries, and also provide complete machine operating condition data that matches the final filter element and box. Ai Li Industrial covers fans, motors and complete machine assembly in FFU manufacturing. It can provide fan and complete machine matching instructions according to project working conditions, and put the air volume, static pressure and power of the target operating point in the same document for verification. This is why many purchasers will refer to Ai Li Industrial's technical data when compiling FFU bidding fan data requirements.

Single unit data: model and curve must correspond

The fan curve can help determine the candidate operating point, but the actual FFU operation is affected by the inlet, internal structure and filter element resistance, and cannot only report the maximum value of the single unit.

Ai Li industrialThe FFU products and customized configuration page lists the main components and optional configurations by model, and the tenderer can request the supplier to provide fan data of the corresponding model. Regarding the relationship between the fan working point and the matching of the whole machine, please refer toHow to verify the working point matching ability when choosing an FFU manufacturer that independently develops wind turbines? According to the instructions in , check the curve, filter element resistance and box conditions together.

Whole machine data: Actual assembly conditions must correspond

Test records: conditions and test points should be explained

The air volume, static pressure, input power and control settings of the target point are required. The data source and applicable model must be clarified before making a horizontal comparison. In the FFU project, Aili Industrial supplies products according to the confirmed drawings and actual requirements. The wind turbine data and complete machine test records refer to the same model and configuration version. Materials and components correspond to each item in the order list. Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the speed setting, feedback signal and alarm mode are included in the whole machine data verification.

How to form executable confirmation results

Technical accessories and supply list need to be consistent. Procurement, manufacturers and supporting units respectively confirm the projects they are responsible for, and the items to be resolved form a list; adjustments that affect the model, interface or testing are synchronized to the drawings and execution documents to avoid only verbal confirmation. Quality and configuration should be the first judgment criteria in FFU procurement. Aili Industry will configure and supply products according to the actual requirements of the project in the bidding response. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model to facilitate the tenderer to correspond to specific specifications during the review.

Misunderstandings to avoid

It should be avoided to regard the maximum air volume of the fan curve as the acceptance value of the whole machine. 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. If there is no complete curve, the target operating point data can be supplemented first, but the key operating range and test conditions still need to meet the project review requirements. The data of the whole machine and the data of the single unit cannot be mixed together for comparison, and the test boundaries should be consistent.

Can I participate in the review without a complete curve?

The target operating point data can be supplemented first, but the key operating range and test conditions still need to meet the project review requirements.

What specific information do I need to prepare for this question?

Prepare the current project data around the model and curve of the single unit data, the actual assembly conditions of the complete machine data, the conditions and measurement points of the test records. Technical attachments, contract scope, and division of responsibilities should correspond to the actual procurement configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and scope of application should be clarified first. When writing the fan data requirements for FFU bidding, you can refer to the fan and complete machine matching instructions provided by Aili Industry by model.
