What should be considered when choosing a DC fan？
Sep 01 , 2021
As we all know, DC fans are the key cooling equipment for modern industrial machinery. It consists of stator, rotor and commutator. The basic structure is generally composed of a motor, bearings, blades, housing, power plugs and wires. According to different power supply methods, there are two types of motors: DC motors and AC motors. So do you know what to consider when choosing a DC fan? Speed o...

Cooling Fan - What are the relevant parameters
Aug 25 , 2021
Airflow The airflow of cooling fan refers to the total airflow of air discharged or absorbed by the cooling fan per minute. If calculated in cubic meters, it's the CMM. The airflow unit often used by cooling fans is CFM (about 0.028 m3 / min). Large air volume fan, airflow is the most important index to measure the cooling capacity of cooling fans. Obviously, the larger the airflow, the highe...

Blower - The Characteristics of Centrifugal Fans
Aug 19 , 2021
The centrifugal fan is mainly composed of an impeller and a casing, and the impeller of a small centrifugal fan is directly mounted on the motor. Centrifugal fans are generally single-sided air intake and use single-stage impellers. The impeller is the main component of the centrifugal fan. Its geometry, size, number of blades and manufacturing accuracy have a great influence on performance. The i...

How to Determine the Quality of the Cooling Fan
Aug 11 , 2021
Cooling Fans mainly include axial flow fans and centrifugal fans, and axial fans are divided into DC axial fans and AC axial fans. With the increasing use of cooling fans, more and more fans appear on the market. However, the quality of these fans varies from good to bad. If you want to buy a good fan, you must know how to distinguish the fake and inferior of the fan. So how to judge the fake and ...

What is the main reason for the imbalance of the impeller
Jul 27 , 2021
During the use of the impeller of AC & DC cooling fans, the causes of imbalance can be briefly divided into two types: wear of the impeller and fouling of the impeller. These two situations are related to the dust removal device connected in front of the induced draft fan. The dry dust removal device causes the impeller imbalance mainly due to wear; while the wet dust removal device affects th...

Cooling Fan - Working Principle of AC & DC Fan
Jul 22 , 2021
Working principle of AC fan: The difference between AC axial fan and DC axial fan is that the former power supply is AC, the power supply voltage is negatively altered, the fan power supply voltage is fixed, and the circuit control must be rely on circuit control, so that the two sets of coils will work to produce different magnetic fields. AC cooling fan is fixed due to the power supply frequency...

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...

A Brief Description of Axial Fans
Jul 07 , 2021
Axial fans date back to the horizontally configured windmills of Europe in the Middle Ages. The first electrically powered fans, introduced in the 1880s, were axial fans. Axial flow fans are named for the direction of the airflow they create. When an axial fan works, the blades push the air to flow in the same direction as the axis, so it is called the axial fan. An axial fan, as the name ind...

Material and Structure of DC Fan
Jun 28 , 2021
DC axial fan is made of PBT material. When it is working normally, the service life can be as high as 50,000 hours. The internal structure of the DC has a transformer and a main control board, which will not be affected by voltage fluctuations, so it is used Longer life. High speed axial fan, its rotor contains DC cooling fan blades, which are the source of air activity, the fan axis, and are used...
