How to represent different models of centrifugal fan and axial flow fan

Release Time：2021-07-20

Centrifugal fans are generally composed of impeller, casing, coupling and shaft. The impeller is mainly used to generate wind pressure and transmit energy. The casing is responsible for introducing and discharging gas. The coupling is used to connect the motor and the fan. The shaft is responsible for fixing the impeller. The axial flow fan is mainly composed of hub, blade, shaft, casing, air collector, streamline body, rectifier, diffuser, air collector and streamline body, the impeller is composed of a hub and a blade, and the impeller and the shaft constitute a rotor supported on a bearing.
The difference between centrifugal fan and axial flow fan 1. The exhaust direction of the two, the air inlet and exhaust outlet of axial flow fan are on a parallel line, so the exhaust direction of axial flow fan is straight along the axis, and the exhaust direction of centrifugal fan is perpendicular to the air inlet, so the exhaust direction of centrifugal fan is 360 °.
The axial flow fan has slow cooling, good cooling effect, low unit energy consumption, easy to grasp ventilation opportunities, not easy to appear fog, centrifugal fan cooling, obvious precipitation effect, short ventilation time, high unit energy consumption, poor grasp of ventilation opportunities, easy to appear fog phenomenon, different levels of device difficulty, axial flow fan is usually directly mounted on the wall or connected with air ducts, so the device is relatively simple, the device of the centrifugal fan is relatively complex.
The motor connection mode of centrifugal fan is different. The motor of axial flow fan is generally installed in the body of the fan. The motor of centrifugal fan is connected by the shaft. The motor of centrifugal fan is generally cylindrical. The axial flow fan is generally snail shaped. The air volume and air pressure of centrifugal fan are different. The air volume and air pressure of axial flow fan are relatively small. There is no air pressure at all. The air volume and air pressure of centrifugal fan are relatively large, if the pipe resistance is large, the pumping air interval is far, the axial flow fan proposes to use the centrifugal fan.
In our country, the model of axial flow fan series is expressed in form, and the model of single tea is expressed in form and variety.
Axial flow fan impeller number code: single-stage impeller does not indicate, double-stage impeller with "2" said.
Purpose code of axial flow fan: as specified in table 1-03.
Axial fan impeller hub ratio: the impeller bottom diameter and outer diameter ratio, take two integers.
Axial flow fan rotor position code: horizontal with "A" said, vertical with "B" said, the product without rotor position change can not be said.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong, the hometown of FRP in China. The company has Grade II qualification for fire protection facilities engineering, Grade II qualification for construction mechanical and electrical installation engineering, Grade II qualification for environmental protection engineering, and safety production license. It is the first in the industry to pass ISO9001 quality management system certification, ISO14001 environmental management system certification, OHSAS18001 occupational health management system certification, and an axial fan invention patent, A fan utility model patent, environmental assessment, safety assessment, three simultaneous and other procedures are complete.
