The cooling fan is widely used in daily life, such as inverter, inverter power supply, inverter, inverter power supply, electric welding machine, cabinet, electrical box, LED display frequency, spark machine, packaging machine, computer case, electric vehicle charger, medical equipment, instrument equipment, etc.All the electrical and electronic design engineers who need to use cooling fans must determine the amount of air needed to heat a particular system, which depends on knowing how much power the system consumes and whether it can take away enough heat to prevent the system from overheating.

The fact shows that the service life of the system will be reduced due to the lack of cooling system, so the design engineer should also understand that the sales volume and price of the system may decline because the service life of the system does not meet the user's expectation.In addition, the fan is also prone to the following faults in use. I will explain to you today, so that you can timely check the blade for cracks or cracks in daily use.This phenomenon often occurs in some large power plants, the most serious even the impeller flying accident;

Motor failure, such as over current, when seriously burned the motor;Blade wear.Mainly occurs on the induced fan.

Electrical equipment input timing is not good or electrical fault, resulting in induced fan wear.This is coal-fired power station induced fan most easily the breakdown.

Oil station oil leakage, adjusting oil pressure unstable.It not only affects the regulating performance of the fan but also threatens the safety of the fan.

Once the axial fan of the cooling fan used in the above mentioned phenomena occurs, it must be stopped for inspection, and it cannot be started again. Otherwise, it will cause great damage to the fan.There is no problem with the mechanism of the fuselage itself. Is the starting design reasonable?The hidden trouble left during installation, such as imbalance of shafting or poor connection, leads to large vibration of fan, easy damage of bearing and coupling;If none of these reasons are true, consider whether the fan is not a good choice.
