Conventional Nissan radiator fans are mainly divided into two categories from bearing, one is oil bearing and the other is double ball bearing. The life of Nissan radiator fan is mainly related to bearing, of course, under the premise of stable reliability.
In the environment of normal temperature of 25 degrees and humidity of 60%, the life of the double-ball bearing Nissan radiator fan is 50,000 hours. This life is also the ball bearing given by NMB Japan.
The life of oil-bearing bearings is 20,000 hours, which is also the life of oil-bearing bearings. Of course, some manufacturers will advocate that oil-bearing bearings can reach 30,000 hours, 40,000 hours, and need to be used with caution.
In fact, the environment in which we use the Nissan radiator fan is often a high temperature, dusty environment, so that the life of the Nissan radiator fan is not small, such as high temperature, the life of the Nissan radiator fan with oil bearing will plummet. The higher the temperature, the shorter the life.
Many people choose Nissan radiator fans, they worry that their power supply voltage instability will damage the Nissan radiator fan, so they often ask the voltage range of the Nissan radiator fan they choose, the voltage of the Nissan radiator fan is 5V. , 12V, 24V, 48V
Nissan's radiator fan's working voltage range is generally +/-10% of the rated voltage. Up and down floating is no problem. Operating within the working voltage range does not mean that the low voltage and the high voltage are also the same. The fan will increase with the voltage, the speed will increase, the current will rise, and the motor temperature will increase.
Nissan radiator fan with rated voltage of 5V, working voltage range is 4.5V-5.5V
Nissan radiator fan with rated voltage of 12V, working voltage range is 10.8V-13.2V
Nissan radiator fan with rated voltage of 24V, working voltage range is 21.6V-26.4V
Nissan radiator fan with rated voltage of 48V, working voltage range is 43.2V-52.8V
For some ultra-high-speed Nissan radiator fans, the lower limit of the voltage can be lower. For the ultra-low-speed Nissan radiator fan, the lower limit of the voltage may be higher. Lower speeds may not start working at low voltages.
