What is the overall structure of the centrifugal fan

Centrifugal fans are based on the basic principle of converting kinetic energy into potential energy, using high-speed centrifugal impellers to accelerate the gas, then slowing down, changing the inflow, and converting kinetic energy into potential energy (working pressure). In a single-pole centrifugal fan, the gas enters the centrifugal impeller from the radial direction, and the gas changes to the axial direction when passing through the centrifugal impeller, and then enters the diffuser.

Wuxi Lida Fan Factory was founded in 1993, covering an area of ​​18,000 square meters and a building area of ​​9,300 square meters Modern standard workshop, with strong production and testing equipment, strong technical force. Over the years, we have cooperated closely with scientific research units and fan designers to develop and produce WZF series forward-inclining multi-blade belt-driven air-conditioning centrifugal fans.

Today, the editor of Lida Fan will talk to you carefully: the assembly requirements of the main shaft of the centrifugal fan:

1. The centrifugal fan consists of a casing, a main shaft bearing, a centrifugal impeller , Roller bearing transmission mechanism and motor and other components.

2. Outer shell: Made of carbon steel plate, it can be driven reliably. It can be divided into full-staff type and semi-closed test. The semi-closed test is conducive to maintenance.

3. Centrifugal impeller: It is composed of leaves, trend pattern front disc and flat front disc.

4. Rotor: Static balance and rotor dynamic balance should be done to ensure smooth rotation and high performance.

5. Part of the transmission device: it consists of a main shaft bearing, a roller bearing box, a needle bearing and a transmission belt pulley (or coupling).
