Fans are common equipment in our lives, and there are various types, including low-pressure fans, high-pressure fans, ordinary fans, and anti-corrosion fans. That being the case, let me introduce a kind of anti-corrosion high- pressure fan in the fan below. Let's take a look.
According to different gas flow directions, anti-corrosion fans are mainly divided into centrifugal anti-corrosion fans and axial anti-corrosion fans.
Centrifugal anti-corrosion fan
When the centrifugal anti-corrosion fan works, the motor (motor) drives the impeller to rotate in the volute casing, and the air is sucked in from the center of the impeller through the suction port. Due to the dynamic action of the blade on the gas, the gas pressure and speed are increased, and under the action of centrifugal force, it is thrown along the blade path to the casing and discharged from the exhaust port.
Composition structure: The centrifugal anti-corrosion fan is mainly composed of an impeller and a casing. The impeller of the small fan is directly installed on the motor, and the large-scale centrifugal anti-corrosion fan is connected with the motor through coupling or a pulley. Centrifugal anti-corrosion fans generally use single-side air intake and use single-stage impellers; those with a large flow can be air-intake on both sides and use two back-to-back impellers, which are also called double -suction centrifugal anti-corrosion fans.
Axial anti-corrosion fan
When the axial-flow anti-corrosion fan is working, the motor drives the impeller to rotate in the cylindrical casing, and the gas enters from the collector, obtains energy through the impeller, increases the pressure and speed, and then discharges in the axial direction. There are three layout forms of axial flow fans: vertical, horizontal and inclined. The diameter of the small impeller is only about 100 mm, and the large one can reach more than 20 meters.
Composition structure: small low-pressure axial flow anti-corrosion fan is composed of impeller, casing and current collector and other components, usually installed on the wall of the building; large high-pressure axial flow anti-corrosion fan consists of current collector, impeller, streamline body, and casing, Diffusion tube and transmission components. The blades are evenly arranged on the hub, and the number is generally 2-24. The more blades, the higher the wind pressure; the blade installation angle is generally 10° ～45°, the larger the installation angle, the greater the air volume and pressure.
1. Low-pressure anti-corrosion fan
The inlet of the fan is under standard atmospheric conditions, and the full pressure of the anti-corrosion fan is an anti-corrosion fan with PtF ≤ 1kPa.
2. Medium pressure anti-corrosion fan
The inlet of the fan is under standard atmospheric conditions, and the total pressure of the anti-corrosion fan is 1kPa
3. High-pressure anti-corrosion fan
The inlet of the fan is under standard atmospheric conditions, and the total pressure of the anti-corrosion fan is 3kPa
The introduction of the anti-corrosion high-pressure fan is here. If you want to know about the anti-corrosion high-pressure fan, you can understand it through the above article, but if you want to know more about the anti-corrosion high-pressure fan, it is recommended to consult some professional fan websites. Understand, and finally, hope that the above content can help everyone.
