Fan classification and application fields
Fan overview: A fan is a machine used to convey gas. From an energy point of view, it is a machine that converts the mechanical energy of a prime mover into gas energy.
According to the structure and working principle, the following fans are classified: centrifugal fans, mixed flow fans, axial flow fans, cross flow fans
Application of fan
Fans are widely used in various industrial sectors. Generally speaking, centrifugal fans are suitable for small flow and high pressure places, while axial flow fans are often used for high flow and low pressure. Different types should be selected according to different situations. Fan classification.
Boiler fan can choose centrifugal or axial flow according to the specifications of the boiler. According to its role, it can be divided into boiler fan-sending air to the boiler; the boiler induced fan draws the flue gas from the boiler.
This type of fan is generally used for ventilation and heating and ventilation of factories and various buildings. The pressure is not high, but the noise requirements are low. Centrifugal or axial flow fans can be used.
3. Fans for industrial furnaces (chemical iron furnaces, forge furnaces, metallurgical furnaces, etc.)
This type of fan requires high pressure, usually from 2940 to 14700N / m2, which is the range of high-pressure centrifugal fans. Because the pressure is high and the peripheral speed of the impeller is large, the impeller should have sufficient strength during design.
It has two types: one is the main fan (also known as the main fan), which is used to deliver fresh air to the underground, and its flow rate is large. It is more suitable to use the axial flow type, which is also useful for centrifugal. The other is a local fan ( It is also called local fan), which is used for ventilation of the working face of the mine. Its flow and pressure are small, and explosion-proof axial flow fans are mostly used.
5.Pulverized coal fan
Centrifugal fans are mostly used to transport coal powder in the boiler combustion system of thermal power stations. Pulverized coal fans can be divided into two types according to different uses: one is a silo type pulverized coal fan, which blows the pulverized coal in the silo from its side into the furnace. The exhaust pressure is high; the other is a direct blowing pulverized coal fan, which directly sends pulverized coal to the furnace. Because pulverized coal wears heavily on impellers and body shells, wear-resistant materials should be used
Precautions for the application of high-pressure blowers in the industry:
Induced draft fan is a boiler auxiliary equipment with poor working conditions. As we all know, it works in dusty airflow. The fly ash in the coal-fired boiler marriage gas will cause wear on the induced draft fan and will also deposit on the induced draft fan blades. Due to the uneven ash deposition and wear , the flat handle of the fan is damaged, causing vibration, and some boilers cannot even operate normally because of this. 炉，引风机则比较容易积灰，尤其是防尘器工作不良时，水点飞城，鼓风机厂家去哪里，烟气带水，引风机叶片积灰更为严重。 Said one boat, for boilers used in dust collectors, the induced draft fan is more likely to wear, while for boilers using wet dust collectors , the induced draft fan is more likely to accumulate dust, especially when the dust collector is not working properly, City, where the blower manufacturers go, the flue gas carries water, and the dust accumulation on the induced fan blade is more serious.
The type of high pressure blower also has a significant effect on the degree of wear. Generally reflect that IDM fan is more wear-resistant than 7-29 fan; single straight fan 5-48, 6-30 fan than 4 72, o. 6-160. —E wing type wear-resistant. We believe that the influence of fan form on wear is mainly due to aerodynamic reasons. If the design of the fan is reasonable so that the particles in the airflow are evenly distributed, which is better for Tianjin blower manufacturers, and does not cause concentrated wear, the service life of the fan is long. 用时间长。 The IDM fan in a certain factory wears evenly, so its use time is long.
外，1DM型风机为后弯机翼型风机，气流与叶片的作用不如前弯式叶片的7—29型风机强烈，因此其耐磨性也较好。 In addition , the 1DM fan is a backward-bending airfoil fan, and the effect of air flow and blades is not as strong as that of the front-bending 7-29 type fan, so its wear resistance is also good. Generally speaking, curved fans with the same diameter are more prone to wear.
Here we need to point out where Tianjin blower manufacturers go. When the backward curved airfoil fan is used for dr powder fan and induced draft fan, it must be taken into account that when the front of the wing? . In the selection, design and manufacturing, full attention should be paid .
