Classification of blowers
Fans have different standards for classification. Different types of fans have different properties and different functions. The classification of blowers is mainly based on the application of blowers in practice.
Jin Blower Group Co., Ltd. has organized the classification standards for blowers for everyone.
Divided by wind pressure: According to the pressure of the fan, the fan can be divided into low pressure fan, medium pressure fan and high pressure fan. Its pressure range is as follows: Low pressure: Fan full pressure H ≤ 1000Pa
Medium pressure: 1000Pa <H ≤ 3000Pa. High pressure (mostly low-pressure and medium-low pressure fans are used in centrifugal fan ventilation projects): 3000Pa <H ≤15000 Pa
It can be divided into general-purpose fan, dust exhaust fan, industrial ventilation fan, boiler induced fan, mining fan and so on.
Fans are widely used in tunnels, underground garages, high-grade civil buildings, metallurgy, factories and mines and other places for ventilation and high-temperature smoke exhaust.
According to different purposes, the commonly used fans can be divided into the following types:
风机 Power Station Fan
⑶General centrifugal fan
⑷General axial flow fan
⑹Sewage treatment fan
⑺High temperature fan
⑻Air conditioner fan
尘 Dust extraction fan
⒃Boiler Induced Draft Fan
Mine fan can be divided into: main fan, auxiliary fan and local fan according to different uses. The main fan is used for the ventilation of the whole mine, the auxiliary fan is used for the air volume adjustment of a branch air path in the ventilation network, and the local fan is used for the ventilation of local places.
Sewage treatment fans can be divided into centrifugal fans, high Swiss fans, side flow fans, water ring fans, etc.,
Divided according to the principle: can be divided into centrifugal fans and axial flow fans for water treatment blast aeration; sewage and aeration in hospitals and laboratories; vacuum feeding in the printing industry; electroplating tanks and industrial wastewater; Supply of gas sources for plastic welding and blowing; spraying of burners, glass industry and others;
Divided according to bearing technology: can be divided into general mechanical bearing blowers, shaft suspension bearing blowers, air suspension bearing blowers.
How centrifugal blowers work
The working principle of a centrifugal blower is similar to a centrifugal fan, except that the compression process of air is usually carried out under the action of centrifugal force through several working impellers (or several stages). The blower has a rotor that rotates at a high speed. The blades on the rotor drive the air at high speed. The centrifugal force causes the air to flow in the involute-shaped casing along the involute to the fan outlet. The new air is replenished from the center of the case.
The working principle of the single-stage high-speed centrifugal fan is: the prime mover rotates the impeller at high speed through the shaft, the airflow enters the high-speed rotating impeller from the axial direction of the inlet, and the radial flow is accelerated. The deceleration of the flow direction reduces the kinetic energy of the high-speed rotating airflow into pressure energy (potential energy), which keeps the fan outlet at a stable pressure.
In theory, the pressure-flow characteristic curve of a centrifugal blower is a straight line. However, due to the frictional resistance and other losses inside the fan, the actual pressure and flow characteristic curve gradually decreases with the increase of the flow. The power of the corresponding centrifugal fan- The flow curve increases with increasing flow. When the fan runs at a constant speed, the operating point of the Tianjin blower will move along the pressure-flow characteristic curve. The operating point of the fan during operation depends not only on its own performance, but also on the characteristics of the system. When the resistance of the network increases, the performance curve of the pipeline will become steeper. The basic principle of fan regulation is to obtain the required working conditions by changing the performance curve of the fan itself or the characteristic curve of the external pipe network.
