What are the basic advantages of axial fans?

The impeller of axial-flow fan is usually made of aluminum alloy. The fan is equipped with aluminum alloy waterproofing tuyere on the outer side of the wall, which can prevent outdoor rain and natural wind from returning indoors. The fan has silencers and built-in sound absorbing materials, and the square integral installation is solid, the vibration is small, the operation is stable, and the noise is low. Xiaobian needs to remind everyone here that before installation, the wall will be reserved by different machine numbers. When installing, the fan will be placed into the wall hole from the outside wall, and rubber or cork can be inserted between the shell and the wall.

  

Axial flow fan is a fan commonly used in ventilation, ventilation or heat dissipation in metallurgy, chemical industry, light industry, food, medicine and civil buildings. It can also be used as a free fan. The fan is different from the centrifugal fan. Its working principle is that the air flow in the same direction as the axis of the fan is called the axial flow because the gas is parallel to the axis of the fan.

  

Axial flow fans should pay attention to the following requirements in maintenance.

  

The production of axial fan is mainly made up of explosion-proof motor, fan blade, air duct and so on. The fan blades adopt large chord length, space distortion and inclined structure wide blades, so that they can achieve the required air volume and wind pressure under the premise of low speed drive. The impeller is installed in symmetrical form, and according to the adjustment angle, it can achieve positive and negative two-way communication in the same installation position. The wind provides convenience for users to install and use at the scene.

  

   Axial fan The impeller is usually made of aluminum alloy, and the fan is equipped with aluminum alloy waterproofing tuyere on the outer side of the outer wall, which can prevent outdoor rain and natural wind from being poured indoors. The fan has silencers and built-in sound absorbing materials, and the square integral installation is solid, the vibration is small, the operation is stable, and the noise is low. Xiaobian needs to remind everyone here that before installation, the wall will be reserved by different machine numbers. When installing, the fan will be placed into the wall hole from the outside wall, and rubber or cork can be inserted between the shell and the wall.

  

1, low noise, low energy consumption, reliable explosion-proof performance.

  

2, the installation method is flexible and diverse, with wall type, pipeline type, post type and fixed type.

  

3, impeller speed (or motor power or air volume) can be selected according to user requirements.

  

1, the use of the environment should be kept clean and tidy, the surface of the fan is kept clean, and the inlet and outlet shall not have sundries, and regularly remove dust and other debris in the fan and pipes.

  

2, only under the normal condition of the fan, it can be operated. At the same time, it is necessary to ensure that the capacity of the power supply facilities is adequate, the voltage is stable, and the operation is strictly prohibited. The power supply lines must be private lines, and the temporary lines should not be used for a long time.

  

3. During the operation of the fan, it is found that the fan has abnormal sound, the motor is seriously heated, the shell is electrified, the switch is tripped, and it can not start. In order to ensure safety, it is not allowed to carry out maintenance in the operation of the fan. After maintenance, it should be tested for five minutes or so.

  

4, according to the use of environmental conditions, it is necessary to add or replace grease to bearings at irregular intervals (motor bearing bearings do not need to replace grease during service life). In order to ensure good lubrication in the running process of fans, the number of refueling times is not less than 1000 hours / times closed bearings and motor bearings. Zl-3 1/3 grease is used to fill the inner and outer rings of bearings.

  

5, fans should be stored in a dry environment to avoid motor dampness. When the fan is stored in the open air, there should be some defensive measures. During storage and handling, the blower should be prevented from bumping, so as not to damage the fan.
