In our daily life, there are many places to use the cooling fan, especially the air purifier.
Different cooling fans are used in different places with different requirements. Choose according to oneself actual situation, be the most effective.
In addition, different materials, in the erosion resistance, the effect is also different. For example, copper radiator fan and steel column cooling fan. In the middle of practical application, the air velocity of steel column type radiator is generally low, and there will be hot and dry conditions. However, the copper channel radiator fan can avoid this problem very well. In addition, in the actual energy consumption process, the copper channel radiator fan is much higher than those of the steel radiator fans.
If it is random to carry on the work of mixing, the air purifier cooling fan to our normal use, but has very big influence. Firstly, the material of the cooling fan is different, and there is a big difference in the resistance coefficient. If the vehicle in the process of driving, a heating system on imbalances, and on the potential difference between a potential situation, can lead to a cooling fan by electrochemical erosion, and can't be used normally.
Because of centrifugal fan type classification is different, if use double speed centrifugal fan, so must start slow at startup, also check the fan blade rotation direction is accurate, air purifier cooling fan, fan stationary before you start, in order to prevent the blade in a high-speed operation condition in reverse rotation.
No matter whether the centrifugal fan is faulty or not, first of all, ensure that the fan's starting mode is accurate. Because the starting mode of the centrifugal fan mainly has full pressure start and down pressure start, regardless of the choice of startup mode, it is necessary to pay attention to the current size. Under normal circumstances, the rated current of the full voltage starting current is 5-7 times, and the torque is proportional to the voltage square. When the power grid capacity is insufficient, the lower voltage starting should be adopted.
Air purifier cooling fan as a complex structure, once the failure, many users will be helpless. Because there are many types of centrifugal fans, there are different faults. If want to solve all kinds of centrifugal fan fault, make use of a centrifugal fan can reach the best state, need from the debugging of the fan, so can to a certain extent, solve the problem of some fan fault, to ensure the efficient use of the fan.
