Q:What is the meaning of the residual pressure in the fan equipment parameters?
Air conditioning units or new air units often installed in the final fan, the fan outlet high wind speed, high pressure, static pressure is small, the project often installed at the exit muffler static pressure box, reduce the dynamic pressure, increase static pressure, , Muffling effect.
Q:How to judge the fan left and right rotation?
According to the National Air Conditioning Equipment Quality Supervision and Inspection Center for many years the fan test shows that many fans in the rated operating conditions are problems, so the need to strictly in accordance with product standards require the production and manufacture of fans.
Q:What kind of duct valves are required in the exhaust duct and near the fan?
Air volume control valve is the industrial plant civil construction ventilation, air conditioning and air purification works indispensable central air conditioning end fittings, generally used in air conditioning, ventilation system pipes, used to adjust the amount of air flow, can also be used for fresh air and back Mixed with wind.
Q:What is the working principle of centrifugal fans?
Centrifugal fan working principle and turbine compressor is basically the same, are due to low gas flow rate, the pressure change is not
Q:Axial fans, centrifugal fans are called blowers?
Can also be used axial fan design; can also use axial flow drum / induced fan design, depends on what type of equipment you test and test equipment on the pressure distribution requirements
Q:How can a more intuitive distinction between centrifugal fans and axial fans?
The 3, oblique flow fan, also known as mixed flow fan is between the axial fan and centrifugal fan between the fan, oblique fan of the impeller so that the air is doing both centrifugal and axial movement, the movement of the shell of the mixture of axial flow and Centrifugal two forms of movement. Mainly used for mine ventilation and tunnel ventilation.
Q:What is the car blower?
At the same time can keep the cylinder gas does not return, such blower is also known as the vane blower.
Q:What is the difference between an axial fan and a centrifugal fan?
The former often installed in the air conditioning unit into, exit, boiler drum, induced draft fan, and so on. The latter is often installed in the duct, or the duct outlet front.
Q:What are the ventilation ducts for wind turbines?
8.5.7 Insulation materials, silencers and adhesives for pipes and equipment shall be non-combustible materials or refractory materials.
Q:Why should the safety valve be installed at the Roots blower exit?
The Roots blower is "cyclone" structural relationship, the air "out" fan cavity,
