With the development of the fan industry, there are more and more types of fans. Blower is the most common one. It can save electricity. It has the advantages of reducing energy consumption and saving production costs. It has been adopted by more and more users. In addition to the most basic ventilation effect of the blower itself, the blower is also superior to other types of fans in all aspects. In what ways does the blower work?

Ordinary hair dryer has the following working principle:

1. Rotary hair dryer working principle:

Rotary blowers are compact and are generally powered by motors. Air converter. A blast body. Gas chamber. Base (and fuel tank). The dripping nozzle consists of six parts. The blower relies on the eccentric rotation of the rotor in the cylinder, so that the volume change between the four blades on the rotor slot sucks in, compresses, and spits out air. When the blower is running, the pressure difference is used to automatically deliver lubrication to the dripping nozzle and drip into the cylinder to reduce friction and noise, and to keep the gas in the cylinder from returning.

2. Centrifugal blower working principle:

The blower usually has a high-speed rotating rotor. The high-speed movement of the air is driven by the blades on the rotor. The centrifugal force causes the air to flow through the fan outlet along the involute in the involute-shaped casing, with a certain wind pressure. Fresh air is injected through the center of the shell. In fact, the working principle of a centrifugal blower is the same as that of a centrifugal ventilator, except that it is compressed under the action of centrifugal force, usually through several working impellers.

The fan can be adjusted by changing the performance curve of the fan itself or the characteristic curve of the external pipe network. The working state of the blower during operation is related to the system characteristics in addition to its own performance. When the resistance of the pipe network increases, the pipeline performance curve becomes steeper.

3. Roots blower working principle:

Roots blower is a constant volume fan, the air volume transported by it is proportional to the number of revolutions. Compared with the two-blade type, the three-blade impeller performs 3 inhalations per rotation of 2 blades, and the gas pulsation is reduced, the load change is small, and the mechanical High strength, low noise, low vibration.

Each impeller is maintained at the correct phase by the synchronous gear, which avoids the touch phenomenon, makes it high-speed, and has a simple structure, no internal lubrication, stable operation, stable performance, wide application range, and wide application range.

After the above introduction, I believe everyone has a deeper understanding of the working principle of the blower. Because the fan has these advantages, it has been used by more and more users and can be widely used in chemical industry. Food. Building materials. Mine. Textile. Pneumatic conveying. Sewage treatment and other industries.
