Q:How to deal with axial fan noise?
The turbulence of the fan in operation will also produce a part of the noise, eddy current noise is mainly due to a certain turbulence flow of gas flow to the blade when the flow turbulence noise. Airflow through the blade surface due to pulsating turbulent surface layer of turbulence generated boundary layer noise and some other reasons.
Q:What is the difference between air compressor and blower?
he main differences are as follows: 1, both can produce pressure and flow, but the use is not the same, the blower used in the sewage plant and tap water, air compressor use is very wide.
Q:How to determine the direction of centrifugal fan?
When the impeller is counterclockwise rotation and the fan outlet in the lower right to obliquely above 45 degrees blowing gas called the left 45 degrees
Q:What is the difference between the fan and the compressor?
The At this time where the first compression, and then with the continuous rotation, the compression chamber volume is reduced. Since the compression process is carried out under full back pressure. Thus inefficient. Noise.
Q:Is the fan pressure static pressure?
In the choice of air conditioning or fan, often encounter static pressure, dynamic pressure, full pressure these three concepts. According to the knowledge of fluid mechanics, the vertical force acting on the unit area is called pressure
Q:What is the difference between an axial fan and an axial fan?
While the radial fan operates, the blades push the air to flow in the direction perpendicular to the axis (ie, radial), hence the runoff fan. Axial fans are divided into large axial fans, medium axial fans, small axial fans, according to the needs of the use of local choice of axial fans.
Q:What is the difference between centrifugal fans and centrifugal fans?
As the inhaled air is absorbed by the exchanger when some heat, so the air is air-cooled. The heat pump absorbed by the exchanger is transferred to the outside through the fluoride force, and the outdoor unit compresses the fluorine force and releases the heat and discharges it into the atmosphere. The main use of gas compression when the heat, the principle of endothermic when the endothermic. The use of fluoride pressure pressure pressure cycle of the indoor heat absorption to the outside.
Q:What is the fan D drive?
Fan without additional bearing support, impeller and motor direct drive;
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:Why should the safety valve be installed at the Roots blower exit?
Roots blowers and centrifugal fans in the working principle has a fundamental difference
