What is the reason for the slow cooling fan speed?
2022-07-12
The working principle of the cooling fan is realized by energy conversion, namely: electric energy → electromagnetic energy → mechanical energy → kinetic energy. The circuit principle is generally divided into various forms, and the performance of the fan will be different if the circuit used is different.
The speed of the cooling fan depends on the voltage, the angle and diameter of the fan blades, the number of fan blades and the bearings. So, what is the reason for the slow speed of the cooling fan?
The main 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 air pressure of the cooling fan is insufficient, the speed of the fan will also be affected.
1. The external environment (such as sand, high temperature and low temperature) will also affect the speed of the cooling fan.
2. Check whether the cooling fan does not need to be cleaned for a long time, because the accumulation of dust and impurities makes the fan run. Lowering the bottom speed requires more effort.
3. Check whether the cooling fan is installed correctly. If the installation is not correct, if the fan is loose, the fan speed will also drop to the bottom.
There are six key points for choosing a DC fan:
First. Choose a goal that can achieve large air volume. We need to see if the large air volume value is what we expect.
Second. Choose to achieve the goal of small size. Choose a small-sized cooling fan according to the environmental requirements of our site.
Third. Choose a goal that can achieve low noise. The level of noise is always a criterion for the quality of the fan. So choose this aspect carefully.
Fourth. Choose to achieve the goal of reducing power consumption. Energy saving is a big goal when we choose a cooling fan.
Fifth. Choose a goal that uses a long life name. Being able to work long hours is our necessary choice.
Sixth. Choose low-cost targets. This is a very real problem
