The cooling fan that is now assembled on the car, in order to achieve the purpose of rapid cooling of the engine, is electronically controlled. That is to say, if the temperature of the engine is too high, the electronic control system will turn the fan up and wait for the temperature. When it comes down, it will stop the rotation of the fan. Generally speaking, the cooling fan has high speed and low speed when it is running, so as to adapt to different engine operating conditions and maintain the normal operation of the engine.
There are problems with the cooling fan, and there are many hidden dangers.
In June 2015, Porsche filed a recall plan with the General Administration of Quality Supervision, Inspection and Quarantine, recalling a total of 58 Porsche brand cars. As a representative of a luxury car, what is the reason for Porsche's recall?
It is understood that this recall of Porsche's imported 918 Spyder car is due to some problems with the left rear radiator fan in the engine compartment of the vehicle. If large friction occurs, it will cause visible damage to the line insulation, which will not only gradually lead to heat dissipation. The fan stops working and may also cause a short circuit in the heat conducting plate, which may cause the vehicle to catch fire in extreme cases. It can be seen that although the cooling fan is only a small part of the car, it is also a part that cannot be ignored.
Car cooling fan low speed, idle speed jitter? Cooling fan manufacturers look over | dynamic balancing machine
We must be clear that the performance of the car cooling fan does not mean that the larger the fan blade, the better the heat dissipation performance, and the air volume is not a factor that affects the heat dissipation.
If the car cooling fan has severe jitter at low speed and idle speed, it is likely that there is a large imbalance in the interior of the car cooling fan.
What should I do if there is a large imbalance in the cooling fan? Don't be afraid, there is a special balancing machine for Zhuo Xuanjin cooling fan.
Zhuo Xuanjin's new upgraded cooling fan balancing machine
From the appearance is not amazing to the instrument, Zhuo Xuanjin cooling fan balancing machine has been greatly adjusted after the upgrade, the newly added automatic protection safety door can better protect the safety of operators.
What changes is not just the appearance, but also its inner.
The new version upgrades the cooling fan balancing machine, which is specially designed for the car cooling fan and the car condensing fan assembly. It not only provides balance check for the single fan, but also balance detection for the dual fan. Do you think that is the only way?
Newly added electrical performance test, vibration test and yaw test function, light vibration can also be accurately measured; multi-function fixture can adapt to more varieties, and pneumatic fast home can more easily and quickly clamp the workpiece, saving time and cost. Greatly improve work efficiency.
Still worried about how to improve the balance of the car cooling fan? The cooling fan special balancing machine can be done. Whether in life or at work, there are many high-speed rotating equipment that we use. To ensure the safety of the equipment and its own, it is necessary to maintain the balance of the equipment, so as to meet the structural rationality and extend the service life of the equipment. Improve safety performance.
