Cooling fans are very common in our consumption and life. The working principle of cooling fans is based on energy conversion, namely: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Its circuit principle is generally divided into a variety of ways, the use of different circuits, the performance of the fan will be different.

The speed of the cooling fan depends on the voltage, the angle of the fan blades, the diameter, the number of fan blades and the bearing. So, what is the reason for the slow speed of the cooling fan? Xiao Bian give you find reason:

The main resolution conditions for the speed of the cooling fan are the structure and parts of the fan, the friction of the bearing and the wind resistance of the blade angle. If the wind pressure of the cooling fan is lacking, it will also affect the speed of the fan.

1. The external environment (such as wind and sand, high temperature and low temperature) will also affect the speed of the cooling fan.

2. Check whether the cooling fan can not be cleaned for a long time. Due to the accumulation of dust and impurities, the fan will run, and the bottom speed will be reduced.

3. Check whether the cooling fan is correctly mounted. If the device is not correct, if the fan is loose, the fan speed will also drop to the bottom.

Six key points for selecting a DC fan:

One. Choose a fan that can complete the large air volume. We'll see if the magnitude of the wind is what we're hoping.

2 Choose a fan that can complete the small size. According to our use of the site environment request to choose a small size cooling fan.

Three. Choose a fan that can complete the small noise. The height of the noise has always been a standard for the quality of the fan, so this aspect should be carefully selected.

Four. Choose a fan that can accomplish less power consumption. Energy saving is a big purpose for us to choose cooling fans.

Five. Choose a fan with a long life name. Being able to work long hours is our necessary choice.

VI. Choose a fan with low cost. This is an ideal question.

By controlling the above key points of selecting DC fans, you can select the cooling fan suitable for your brand according to your request. When your DC cooling fan shows the problem of slowing down, you can see if it is the above reason, and stop handling the problem according to finding the reason of slowing down the fan. If you cannot handle it yourself, you can choose the assistance of professionals.
