Industrial centrifugal ventilator with high working efficiency and expansion process

- Nov 03, 2018-

The industrial centrifugal ventilator can be operated according to the user's application and working conditions. The equipment can be converted into potential energy according to the principle of kinetic energy, effectively use its high-speed rotating impeller to accelerate the gas, then decelerate, change the flow direction, and convert the kinetic energy. A potential energy (pressure). In a single-stage centrifugal fan, gas enters the impeller from the axial direction, the gas changes to radial direction as it flows through the impeller, and then enters the diffuser.

Industrial centrifugal fan in the diffuser, its gas changes the flow direction to cause deceleration, such deceleration converts kinetic energy into pressure energy, the pressure increase mainly occurs in the impeller, and secondly occurs in the expansion process, in multi-stage centrifugation In the fan, the return air is used to make the air flow into the next impeller, resulting in higher pressure.

The air inlet of the industrial centrifugal fan adopts a convergent streamline type vortex reduction type, the airflow loss is small, and the working efficiency of the fan is high. The fan casing and the motor are mounted and connected by metal castings. The cooling fan blades are mounted on the motor shaft head. The outer wall of the metal casting is opened with high inlet and outlet pipes to cool the metal castings and the shaft head to ensure the normal operation of the motor at high temperature.

The motor of the industrial centrifugal ventilator adopts a special high-temperature motor, and the fluid part of the fan is made of temperature-resistant material, and the structure of the cooling structure is reliable. Compared with the boiler induced draft fan, the SSD type has the advantages of simple structure, convenient maintenance and high cost performance.
