The main points of using the air purifier cooling fan

Time：2022-04-18Views：0

In our daily life, there are many places where cooling fans are used, especially air purification. Today, Xin Superspeed Company will explain to you the key points of using the air purifier cooling fan:

Different cooling fans, used in different places, have many different functions. Reasonable and effective according to their actual situation, to make purchases, is to be effective.

In addition, different materials have different effects and capabilities in terms of corrosion resistance. Such as copper radiator fans and steel column radiator fans. In the actual application of the column-type cooling fan, the air flow rate is generally low, which will make people feel dry and hot. However, the copper water channel radiator fan can avoid this problem very well. However, in the actual energy consumption process, copper water channel radiator fans are much higher than those steel column radiator fans.

If it is mixed at will, the air purifier cooling fan will have a very big impact on our normal use. First of all, the material of the cooling fan is different, and the resistance coefficient is also very different. If the vehicle is in the process of driving, there is an imbalance of the heating system and a potential difference between the potentials, which may cause the cooling fan to suffer from electrochemical erosion, and it cannot be used normally.

Because the model classification of centrifugal fans is different, if a two-speed centrifugal fan is used, it must start at a low speed when starting, and check whether the rotation direction of the fan blades is accurate. Activate to prevent reverse rotation of the blades at high speeds. The motor power required by the centrifugal fan refers to the larger power required for the centrifugal fan and the fan box when the air inlet is fully opened under certain working conditions. There is a risk of damage to the motor if the air inlet is fully opened for operation. When the fan is tested, it is better to close the valve on the fan inlet or outlet pipe, and open the valve slowly after operation until the required working condition is reached, and pay attention to whether the running current of the fan exceeds the rated current.

Regardless of whether the centrifugal fan is faulty or not, first of all make sure that the starting method of the fan is accurate, because the starting methods of the centrifugal fan mainly include full pressure starting and reduced pressure starting. Under the circumstance, the current of full voltage start is generally 5-7 times the rated current, and the voltage reduction starting torque is proportional to the square of the voltage. When the power grid capacity is insufficient, the voltage reduction start should be used.
