1. Principle of rotary fan
The rotary fan has an exquisite structure, which is generally composed of six parts: the motor, the gas connector, the centrifugal fan itself, the gas chamber, the base (and the oil tank), and the drip nozzle. The centrifugal fan operates on the eccentricity of the motor rotor offset in the cylinder, and changes the mutual capacity of the four blades in the motor rotor slot to suck in, recompress, and eject gas. The centrifugal fan mainly uses the pressure difference to automatically send the lubricating oil in the oil tank to the drip nozzle during operation. When the fan is running, it drips into the cylinder to reduce friction and noise, and it can also keep the gas in the cylinder from returning.
2. Principle of centrifugal compressor
Centrifugal fans usually have a high-speed rotating motor rotor. The high-speed rotation of the gas is driven by the impeller on the motor rotor. The centrifugal force causes the gas to flow into the centrifugal in the involute gear-shaped housing along the involute gear. At the outlet of the fan, the high-speed cyclone has a certain wind pressure. Although the principle of a centrifugal compressor centrifugal fan is similar to that of a centrifugal fan, the difference is that the air is compressed under the action of centrifugal force, generally through multiple working impellers. During the operation of the centrifugal compressor, it mainly depends on its own characteristics and also on the characteristics of the system. When the resistance in the pipeline increases, the pipeline characteristic curve becomes steeper.
3. Principle of Roots Blower
Roots blower is a kind of capacity centrifugal fan. The air volume conveyed is usually proportional to the speed. Compared with two-blade Roots blower, the three-blade Roots blower is mainly used for three suction and discharge by two impellers per rotation. It can be widely used in various industrial sectors such as chemical industry, food, building materials, mines, textiles, pneumatic conveying, sewage treatment, etc., because of its low load change, small air artery movement, high mechanical strength, low noise and low vibration.
4. Principle of vortex high pressure fan
The impeller of the high-pressure vortex fan is composed of dozens of blades of the same size and shape, which is similar to the impeller of a huge gas turbine. Its working principle The air between the impeller blades is subjected to centrifugal force and moves to the edge of the impeller, where the air enters the annular cavity of the pump body, and recirculates in the same way from the starting point of the blades. The circulating air flow generated by the rotation of the impeller leaves the air pump with extremely high energy for use. The fan adopts a special explosion-proof motor, which is compact in structure, small in size, light in weight, low in noise, and has no water and oil in the air supply.
