Roots Blower
Roots blower is a kind of multi-impeller, friction-free, oil-free impeller fan. The roots fan is characterized by the production of no pulse, high air volume, low noise, and high stability of the wind. Roots blower is widely used in biogas utilization, biomass fuel power generation, grain transportation, wind tunnel experiment and other fields.
Industrial Centrifugal Fan is a general machinery widely used in various industries of national economy. It is the customary abbreviation of gas compression and gas transmission machinery. Generally called fan include fan, blower, compressor.
How to select the fan type
1. When selecting, first find static pressure;
2. Find down according to the column of static pressure to find the required air volume;
3. Read out the shaft power, noise, rotation speed and other parameters;
4. Check whether the performance curve, power curve, external dimensions and so on meet the requirements;
5. Match the appropriate motor upward according to the shaft power X1.1;
6. Selection is completed...
1. Centrifugal Fan blower
Centrifugal fan is a widely used fan type, which can produce high pressure, high suction, suitable for the gas delivery. The centrifugal fan is composed of rotor and stator. Under the action of the rotor, the gas accelerates the rotation, generating kinetic energy, and then it is converted into pressure to transport the gas out. Centrifugal fan is widely used in ventilation, air conditioning, metallurgy, chemical industry, mining and other fields.
2. Axial flow fan
In the gas flow, the flow rate direction of the axial flow fan is consistent with the machine axis direction, which is characterized by the advantages of high flow rate, low pressure, high efficiency and low noise. Axial flow fan is widely used in air conditioning ventilation, cooling, pressurization, drying and other fields.
3. Mixed flow fan
Mixed current fan is a comprehensive product of centrifugal fan and axial current fan, with medium air volume and pressure, high efficiency and low noise. Mixed-flow fan is widely used in ventilation, cooling, pressurization, drying and other fields.
4. Hot air circulation fan
Hot air circulation fan is a kind of fan that transfers heat with high-temperature gas. It is characterized by the ability to heat the gas and then transfer it to the substance that needs to be heated. Hot blast circulation machine is widely used in hot blast furnace, heat treatment furnace, industrial heat treatment, drying and other fields.
What parameters should be provided in the fan type selection?
1. Form, type and use of the fan
2. Installation method
3. Gas composition (including special temperature, humidity, corrosion and impurities)
4. Wind-out direction
5. Indoor installation or outdoor installation
6. Other conditions limited (such as noise less than 60 dBA, etc.)
7. Accessories and special requirements
