Fan Flange

The main function of the excavator fan flange is to connect the excavator engine to the fan, ensuring that they can operate synchronously while also providing sealing and protection.

A flange, also known as a flange collar or rim, is a component used to connect shafts or pipes, primarily for joining the ends of pipes or connecting equipment at inlets and outlets, such as those on a gearbox. In excavators, the fan flange connects the engine to the fan, ensuring that they rotate on the same axis, which facilitates effective heat dissipation. This method of connection not only restores the cooling function of the engine fan but also helps reduce maintenance costs for the vehicle. Specifically, the functions of the excavator fan flange include:

1. Connection and Synchronous Operation: The flange connection ensures that the engine and fan can operate in sync, which is essential for maintaining the normal cooling of the engine.

2. Cost Savings: By modifying the connection method between the engine and the fan, maintenance costs can be reduced, with estimated annual savings of around 9,000 yuan.

3. Sealing and Protection: The flange connection provides good sealing performance, which helps protect the engine from external environmental damage.

Moreover, flanges have a wide range of applications beyond excavators; they are extensively used in various fields, including chemical engineering, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, electricity, aerospace, and shipbuilding. Therefore, the modification and optimization of the excavator fan flange are significant for improving the performance of excavators and reducing costs.
