Automotive Electronics Fan Expertise

Dynamic balance is a research content of rotor dynamics. It refers to the operation of determining the position and size of the imbalance (centrifugal force and centrifugal force couple, see relative motion) generated when the rotor rotates. Therefore, most rotors should be dynamically balanced. The electronic fan is also a rotor, and it runs at high speed. If it is not balanced, the fan will vibrate and the noise will be loud. Sometimes, when the fan splashes on the fan, the noise will become larger. This is the destruction and the fan balance.

The role of the automotive cooling system is to moderately cool the running engine and keep the cooling water within the optimum temperature range. When the engine is working normally, the cooling water temperature should be kept within the range of 80-90 °C.

When the cooling water temperature is low, the fan stops running and the water temperature rises to the optimum value as soon as possible. When the cooling water temperature is high, the fan runs quickly and the water temperature is controlled within the optimal temperature range.

The electronic fan is to control the engine water temperature can not be too high, the water temperature is generally more than 90 degrees, the sensor action, the electronic fan is turned on, the water temperature is lowered, the winter temperature is lower, the water temperature is lower, and the electronic fan is generally not open, in order to protect the engine from being over. Work in cold and overheated conditions.

The factors that affect the fan's work are as follows:

1. When the water tank temperature sensor detects that the water tank temperature exceeds the threshold (typically 95 degrees), the fan relay pulls in. The tank temperature sensor is actually a thermostatic valve, not a water temperature sensor.

2. The fan circuit is turned on by the fan relay, and the fan motor is started.

3. When the water tank temperature sensor detects that the water tank temperature is lower than the threshold, the fan relay is separated and the fan motor stops working.

In order to make the car cooling system better cool the engine, the dynamic balance of the car cooling fan is very important.

Automotive cooling fan balancing machine introduction

The automotive cooling fan balancing machine is a special balancing machine specially designed for automotive electronic fans. It can provide an overall balance service for the automotive electronic fan and water tank electronic fan assembly, and can add calibration equipment based on the balance detection to complete the balance detection at one time. And the steps to correct.

In addition, the car cooling fan balancer can also test the current, voltage, power and other electrical parameters.
