The cooling fan is widely used in many fields. The operation of the machine requires the fan to exhaust heat to ensure normal operation. Once the cooling fan itself has a problem, it will directly affect the service life of the equipment. So what is the root cause of the failure of the cooling fan?
The failure of the cooling fan is generally caused by the following four reasons.
First, the reason for the design of the cooling fan:
The design of the cooling fan is improper, and the cooperation of the parts is not considered in the design, and the dynamic characteristics are poor, causing vibration or noise when the machine is running. The structure is unreasonable and the use of steel is inappropriate, causing stress concentration. The fuselage material is prone to cracks, the material of the parts is not good, the strength is not up to the standard, and accidents are prone to occur during use.
Second, the reason for improper operation of the cooling fan:
The process parameters of the machine deviate far from the design value, which will often cause the machine to maintain over-speed, over-load operation, or low-speed, low-load operation during operation, and cannot reach the working performance of the machine; the operating point is close to or falls into the critical speed zone , The lubrication or cooling of the radiator fan is not in place; improper operation during the process of starting and stopping the machine or increasing speed and reducing speed, causing the machine body temperature to fail to reach, uneven thermal expansion, or temperature overheating, which causes the machine to anneal and lose its original strength .
Third, the reason for the deterioration of the cooling fan itself:
The long-term operation of the machine causes fatigue of the shaft and other parts, which causes partial damage to the rotor. The parts are affected by the impact force and cause surface pitting and partial wear.
Fourth, the reason for the installation and maintenance of the cooling fan:
The heat dissipation fan is improperly installed in the mechanical equipment, the parts are misplaced, or the shafting is poorly aligned, resulting in a large preload, improper placement of the rotor, and failure to perform inspections in accordance with regulations, which destroys the original coordination system of the machine.
