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...

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...

Does the DC cooling fan have an impedance protection function?
Oct 19 , 2021
DC cooling fan is an important cooling equipment for modern industrial machinery. Its basic structure is generally composed of motors, bearings, blades, housing (including fixing holes), power plugs and wires. The motor is the core of the DC cooling fan. It is generally composed of a stator and a rotor. The stationary part of the motor is called the stator, and the part that rotates when it is run...

What are the main reasons for the noise sources of fans?
Oct 26 , 2021
Noise is a kind of noise that makes people feel noisy and boring, and its degree sometimes varies with people's mood. But continuous noise will also pollute the surroundings. The causes of noise generated by general cooling fans can be divided as follows: 1. Noise caused by blade rotation When the blade rotates, it will generate friction or impact with the air. High rpm exhaust fan, the faster the...

Is the service life of the DC fan affected by the environment?
Nov 09 , 2021
In daily life, in order to extend the service life of DC fans and reduce the cost of equipment loss, we will regularly inspect and maintain the DC fans in mechanical equipment. However, as the seasons change, the surrounding ambient temperature will change accordingly. In spring and autumn, the temperature is suitable, the winter is bitterly cold, and the summer is scorching, so is the service lif...

What is the EC fan?
Nov 29 , 2021
The voltage used in electronic products is divided into direct current (DC) and alternating current (AC). Our usual household appliances, such as electric lights, air conditioners, refrigerators, etc., are AC power supply, while we use DC power supply with batteries (such as mobile phones, flashlights, clocks, etc.). In principle, the efficiency of DC cooling fan is higher than that of AC cooling ...

What is the relationship between starting voltage and cooling fan?
Dec 14 , 2021
With the increasing use of cooling fans, many people are interested in the details of cooling fans. Some people will ask whether the low voltage will affect the cooling fans. Low voltage has no effect on the fan, it will only make the fan rotate at low speed, which can prolong the service life of the fan, but low voltage for a long time may damage the motor. Voltage includes starting voltage and o...
