Blower - The Working Principle of Centrifugal Fan
Jul 15 , 2021
Centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Centrifugal exhaust fans can be widely used for cooling and ventilation in air conditioning equipment, household appliances and medical equipment. The working principle of a centrifugal blower fan is basically the same as that of a turbo compressor, except t...

What is the difference between centrifugal, axial and cross flow fan blades?
Sep 26 , 2021
1. Centrifugal fan Centrifugal blower fan is based on the principle of converting kinetic energy into potential energy, using a high speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from the axial direction, changes to...

What are DC Centrifugal Fans?
Dec 21 , 2021
Centrifugal fans are sometimes called radial fans or centrifugal blower fans. They have a motor-driven hub which contains an impeller that discharges air into the housing and then directed to an outlet. The centrifugal fan exhausts air at an angle of 90 degrees (perpendicular to the air inlet). Centrifugal type fans mainly pressurize the air in the blower housing. Compared with axial fans, they pr...

Use of axial fans and blowers
Dec 28 , 2021
In the cooling fan, the DC fan provides variable flow and the AC fan provides constant flow. In addition to AC power supply and DC power supply, cooling fans are usually classified according to the way air enters and exits the fan. In an axial fan, air enters and exits in the same plane. If the airflow leaves in different planes, this is called centrifugal design or blower. Natural convection cool...

Where is the cooling fan used?
Feb 23 , 2022
Cooling fans, as the name suggests, are used for ventilation and heat dissipation. It is widely used in various industries and fields, because in many electronic equipment and machinery, if there is no cooling device installed in the equipment, the working temperature may be too high, which may cause the performance of the equipment to decline, or even be damaged. For normal and efficient operatio...

What will happen if the car cooling fan is not transferred?
Jun 27 , 2022
The cooling fan is one of the indispensable parts of the car. If the cooling fan doesn't work, it will cause the coolant temperature in the engine water tank to be too high. If the water temperature is too high, the water vapor in the water tank will spray out from the pressure relief hole. This situation is more dangerous, and the car can be started only after maintenance. So what are the reasons...

What are the anti-corrosion measures for industrial cooling fans?
Sep 09 , 2022
The production of industrial equipment is inseparable from the accessories industrial cooling fan. The main function of the fan is to dissipate heat, cool and remove dust for various sizes of equipment. The general production environment of industrial equipment is relatively harsh. In order not to shorten the service life of the industrial cooling fan, some treatment will be done for the fan. The ...
