In order to ensure the normal operation of electrical appliances or other digital products, and to ensure that there will be no host high temperature, crash, shutdown, circuit burnout and other failures in the process of use, many people will choose industrial cooling fans pretending to be quality assurance on industrial equipment. The stability of industrial cooling fans is related to many factors, Now let's take a look at several factors that affect its stability.
Whether the quality of the industrial cooling fan is excellent or not will determine its real performance in the actual situation. Customers care about this. In order to eliminate all the factors that interfere with the quality of the fan, customers will sort out each purchase step in turn. It can be seen that there are not a few customers with rigorous and serious attitude. The other part of customers are careless and can not pay attention to the details. You may as well calm down and pay attention to a series of contents described below to avoid ignoring more information.
When the cooling fan is installed near the high-power switch circuit such as UPS, inverter, rectifier, high-voltage power supply or high-voltage switch circuit, due to the strong electromagnetic interference (electromagnetic induction) generated by the circuit or the high-frequency interference generated by the power line of the cooling fan, the induced current may be generated in the bearing of the fan shaft, The oil film on the bearing surface is damaged, and the bearing and rolling surface of the bearing are damaged. This phenomenon is called "electric erosion of fan". After the occurrence of electric erosion, the rotation of the fan becomes not smooth, and abnormal sound is emitted when rotating, and the service life becomes shorter. With the development of high-density packaging, the distance between the switch circuit and the fan becomes shorter and the switching frequency increases, which makes the fan more vulnerable to electromagnetic induction. In the low voltage operation of information / communication equipment, due to the small electromagnetic interference, there will be no electric erosion phenomenon.
SANYO DENKI CO., LTD. has developed and launched the San Ace 250AD φ250 × 99 mm Centrifugal Fan and Splash Proof Centrifugal Fan. These fans feature the highest airflow in the industry.(1)
They are ideal for air conditioning systems and cooling inverters and telecom equipment cabinets.
