Q:How can a more intuitive distinction between centrifugal fans and axial fans?

1, centrifugal fan is to rely on the input of mechanical energy, improve the gas pressure and send the gas to the machinery, it is a kind of driven fluid machinery. Centrifugal fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust and cooling

Q:What is the difference between high pressure air blower and medium pressure air blower?

High-pressure fan, also known as high-pressure blower, is different from the general centrifugal blower fan.

Q:Is the centrifugal fan plugging the air inlet motor?

However, the motor is still running at high speed, the corresponding mechanical loss and other losses, but still continue to consume, and block the air intake of this way to save the electricity is much greater.

Q:What is the basic principle of an axial fan?

When the impeller rotates, the gas enters the impeller from the inlet of the air inlet and is pushed by the blade on the impeller to raise the energy of the gas and then into the guide vane

Q:What is the use of two-speed fan?

The two-speed fan just to overcome this shortcoming, usually as an exhaust fan running, the problem can be found and be repaired in time, always in a good state of preparation.

Q:What are the regulations for the air volume of the exhaust fan?

Bear two or more smoke partition smoke, should be the largest smoke partition area per square meter of not less than 120m3 / h basis.

Q:What is the operation of centrifugal fans and axial fans?

Centrifugal fan is based on the principle of kinetic energy conversion to potential energy, the use of high-speed rotation of the impeller to accelerate the gas, and then slow down, change the flow, the kinetic energy into potential energy (pressure)

Q:What is the effect of the centrifugal fan on the wind pressure?

In contrast, when the fan outlet is small, the air volume decreases, the wind pressure increases and the power decreases.

Q:How to distinguish between the fan coil around?

To determine the left and right type, on the one hand is based on the drawings of the water pipe position, and then check the fan coil samples, the sample for the left, the right type will have a convention.

Q:What is the role of axial fans and centrifugal fans in mechanical ventilation?

5 to axial fan for the advantages of slow ventilation: cooling effect is good; unit energy consumption is low, in the promotion of energy-saving today is particularly important; easy to grasp the ventilation time, not prone to condensation; do not have a separate fan, convenient and flexible. Disadvantages: due to the small amount of air, ventilation time is long; precipitation effect is not obvious, high water grain should not use axial fan for ventilation.
