The damage principle of explosion-proof centrifugal fan is introduced in detail


Explosion-proof centrifugal fanWhat are the damage principles? The following editor will introduce to you.

During the whole process of high-speed operation of the explosion-proof centrifugal fan, it will deal with the hazards of the surrounding environment elements and the equipment itself, which will cause damage. Cause damage to the frosted particles. More serious will endanger the application of centrifugal fan, the damage principle will be introduced in detail below.

The damage condition of explosion-proof centrifugal fans includes many complicated elements, which are usually the result of the combined effects of multiple principles. The fine particles enter the centrifugal impeller and interact with the boundary layer. In the inlet area of ​​the suction filter through the flow channel and all the radial flow channels, most of the fine particles are brought in by the cyclone and under the comprehensive effect of its own inertial force. , It hits the boundary layer with a non-zero angle of attack, and then rebounds into the flow channel. The damage to the raw material of the boundary layer caused by that is a typical erosion damage. In the entrance and exit area of ​​the suction and filtration flow channel, the fine particles exercised a long tens of meters in the flow channel. Turn it over and aim at the boundary layer to have the necessary working pressure effect. The damage to the raw material on the negative side is attributed to the scratch-type fine particle damage. The concentration of fine particles in the area around the working pressure surface increases the damage level of fine particle damage. .

In general, when dealing with explosion-proof centrifugal fan damage, the key to suffer is the damage of fine particles. This requires us to pay attention to the hazards of the surrounding environment when actually operating machinery and equipment, and choose as clean as possible without floating dust. Construction is carried out in a natural environment, if the smoke and dust are too large, it will be very easy to cause damage to the centrifugal fan and cause harm to the aftermath.
