Operation process and advantages of centrifugal Fan for plastic Machinery

Aug 06, 2018

The use of plastic machinery centrifugal fans is characterized by anticorrosion. To a certain extent, it is widely applicable to anticorrosion. Basically, there is no gas and it is chemically produced, that is to say, it can handle any kind of gas. However, the condition is that the temperature of the gas and dust particles should be in accordance with its range of use. Another feature is light weight and low noise, which is one of the reasons many people like to use plastic fans.

The plastic centrifugal fan is installed in the wet environment, the frame and the motor must be thickened with the anticorrosion layer. If installed in the open air environment, it is better to install the sun shading. Check the rotation of the plastic fan regularly, find the abnormal sound, and check the vibration in time.

In the process of operation, the centrifugal fan of plastic machinery is mainly based on the principle that its kinetic energy is converted into potential energy. To a certain extent, the gas is accelerated by its high speed rotating impeller, then decelerated, the direction of flow is changed, and the kinetic energy is converted into potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from axial direction and changes into radial direction when flowing through the impeller, then enters the diffuser. In the diffuser, the gas changes the flow direction and causes deceleration, which converts kinetic energy into pressure energy. The pressure mainly occurs in the impeller, followed by the spreading process. In the multi-stage centrifugal fan, the air flow enters the next impeller with a backflow device, resulting in higher pressure.http://www.jnblower.com/
