How much do you know about how car blowers work?

<> 1. The composition of the blower.

In fact, the blower is mainly composed of six parts, that is:The base also serves as the fuel tank, motor, blower body, air filter, and air chamber drip nozzle. In fact, the blower operates by the eccentricity of the rotor in its body, and the volume between the blades in the rotor groove can be changed in the process of operation, so as to suck in, compress and spit out the air. In this way, it is not very simple, that is, a certain device is used to suck the air in first, and then compress the air and then spit it out, so that the blower can operate.

During operation, the pressure difference of the blower will send the lubricating oil to the drip nozzle, which will then drip the lubricating oil into the cylinder, thereby reducing friction and increasing the life of the blower.

Second, the role of the blower.

With the global warming, the driver's requirements for the riding environment are gradually increasing, and more and more cars are equipped with blowers, so what is the role of the blower? In fact, the blower can make the air in the cabin cold, or change the air or purify the air. The blower can provide a more comfortable environment for the passengers, which can reduce the fatigue of the driver, thereby improving the safety of driving

Nowadays, whether a car is equipped with a blower has become one of the signs to measure whether the car is fully equipped.

Third, the working principle of the blower.

When you turn on the blower switch, if you choose the lowest temperature, it is the external circulation, so that the temperature of the car will increase. Since the inlet of the blower circulation is located on the edge of the front glass of the car or between the engine, the temperature of the blower will be brought into the cabin when it is working, which will increase the temperature of the blower。If you choose the inner circulation, it will blow out the temperature of the car, so that the car will cool down.

If a high temperature is chosen, the evaporator in the blower heats up, the temperature of the wind increases, and the temperature of the car increases.

The function of the car blower is to blow the cold air on the evaporation tank of the air conditioner, or the hot air from the warm water tank, into the car, and there is nothing in the blower just a motor.

I know a lot that the blower of a car is a fan blade that rotates at high speed, and then generates wind energy to cool the car quickly.

The main working principle is to speed up the modulation through the air conditioner, and it can also play a good role in changing the direction and other functions.

The working principle is to use one of its internal devices, and then turn it to achieve the desired effect of a car.

3. The performance of the automobile blower when it fails. When the car blower fails, it will cause the air conditioning outlet in the car to produce no air, or there will be abnormal noise when the blower needs to work. And sometimes when the car blower fails, the air supply volume will decrease, which will affect the cooling or heating effect in the car.

When there is a problem with the car blower, it will affect the normal operation of the air conditioning system in the car. When the blower of the car fails, the owner needs to go to the 4S shop or a professional repair organization to repair the car.

The function of the car blower is to blow the cold air on the evaporation tank of the air conditioner, or the hot air from the warm water tank, into the car. Blowers are divided into:

Roots blowers, blast furnace blowers, magnetic levitation blowers, unipolar high-speed centrifugal blowers, multistage centrifugal blowers and air suspension centrifugal blowers. The blower consists of a motor, an air filter, a blower body, an air chamber, a base, and a drip nozzle.

The blower of the car is a part of the automobile air conditioning system, and its function is to send the air to the HVAC through the blower motor, and the air sent by the blower is cold and hot through the HVAC, and then the cold and hot air comes out of the air outlet.

The main working principle is to carry out external circulation through low temperature, and then achieve a certain effect, so as to increase the temperature in it.

Foreword: Nowadays, people's living standards are getting better and better, so many people have cars at home as an important tool for travel. So do you know what a car blower is made of?

First, the composition of the blower In fact, the blower of the car is mainly composed of six parts, including the base fuel tank, air filter, air drip nozzle, blower body and motor. In the process of rotor eccentric operation, the volume between the blades in the rotor groove can be changed, so that the air can be sucked in, compressed and spit out, so many people say that the composition and operation of the blower is very simple. In the process of running before the ancient style of cycling, the pressure difference of the blower will send the lubricating oil to the drip nozzle, and then the oil nozzle of the car will drip the lubricating oil into the cylinder, so as to reduce friction and increase the service life of the car blower.

Second, what is the function of the car blower Many people actually don't know what the function of the car blower is, this is because with the gradual warming of the global climate, especially in the summer, many drivers and passengers have no way to withstand such hot weather, so they are equipped with a blower in the car, the blower can make the air in the car cold, or for ventilation. The blower can provide a comfortable environment for the passengers, so as to reduce the fatigue of the driver to a certain extent, and provide a guarantee for the safety of the driver and passengers. So now basically every car is equipped with a blower, and it has become a sign to measure whether the car is fully equipped.

3. Conclusion When we turn on the switch of the blower in the car, and then select the temperature as the lowest, so that it is the external circulation, the temperature of the car will increase, if the internal circulation is selected, the temperature of the car will be blown out, so that the car will cool down, if the high temperature is selected, then the evaporator of the car blower will be heated, and at this time it will feel that the car will begin to become warm.

Automobile blowers are mainly composed of six parts. Including motor, air filter, blower body, air chamber, base (and oil tank) and grease nozzle.

I know, this includes the suspension, and then the bearings, and then the mounting plates, the air flow plates, and the screw holes, the impellers, and then also the air inlet and so on.

Mainly by the base tank, air filter, air drip nozzle, blower, these are some very important parts, and it is also very important when assembling.

It is mainly composed of gears, bearings, impellers, and bushings, and the structure is particularly simple.

There are three kinds of originals: 1: motor 2: speed regulating resistor 3 control switch.

Generally, the simplest control method for domestic cars is that the positive pole of the motor is connected to the live wire (some models have relays). The negative pole of the motor is connected to the speed regulating resistor. The first and second gears of the switch (for the heating mechanism controlled by the third gear) are connected to the speed regulating resistor, and the third gear is directly connected to the negative pole.

The principle of a cycling blower should be different from that of a heater. First of all, the heating of the car blower is achieved by heating the air flow through the heat of the engine. The principle of the heater is to use electrical energy to generate heat, and then convection to bring out the heat.

So the essence should be different. But when it comes to blowers, there are many technologies, which may or may not be the same.

The principle of centrifugal fan blower When the motor rotates to push the centrifugal impeller of the fan to rotate, the vapor in the middle of the leaf in the centrifugal impeller also follows the rotation, and throws out this vapor under the effect of centripetal force, and the vapor water flow expands.

There are many reasons why a car blower is not working. I found some in my life and work. Now I share it.

I hope it helps, if the car can start normally, the battery is working normally, and the fan does not turn at all, there are basically three situations: one is that the speed control panel is damaged, which is a universal gas conveyor. It is a machine that converts the mechanical energy of the main engine into gas energy.

At this point, the power supply must be cut off and the two connection points of the two fan outlets and the power line must be separated, otherwise, connect the power supply and carefully measure both ends of the energy line with an electric pen. If one end is connected and the other is not, it means that the energy inline is normal. Different types of fans have different pressure ranges.

When the fan blows, it compresses the air. The pressure ratio is different for different types of fans. Of course, we have to overcome a certain amount of pressure, so this pressure must be taken into account.

The function of a car blower is to blow cold air from the evaporation tank of the air conditioner or hot air from the hot water tank onto the car. After the air flow enters the fan impeller axially, it flows mainly in the radial direction. This type of fan is carried out according to the principle of a centrifugal pump.

Products include centrifugal fans, centrifugal fans and centrifugal compressors.

According to your own economic budget, through the comparison of all aspects, choose the most economical and cost-effective blower, focusing mainly on quality, not brand.

I generally choose a blower with relatively large power, so that there can be a relatively large wind blowing out, and choose some big brands of blowers, so that the quality can be guaranteed.

The first thing I consider when choosing is the quality, and every time I choose, I buy from a 4S store, which is also because it is generally the original material.

A car blower is a motor used to deliver cold or hot air to the cab when the air conditioner is turned on. Increase the flow of the wind by the magnitude of the wind. Give the driver a comfortable driving environment.

The speed regulation of modern automobile blowers is generally controlled by resistance. Because it is a series control of several resistors, its principle is simple structure, easy installation and maintenance, and wide application. The only disadvantage is that the power is on for a long time, the resistor is easy to burn, and it is easy to burn if it is not cooled for a long time.

Therefore, most of the resistance part of the blower is located inside the blower, which is cooled by rotating air supply when the blower is working, so that the resistance of the blower dissipates heat and prolongs the life of the resistance. When the blower switch is at 2, there are 2 resistors in series in the circuit of the blower, and the blower runs at medium speed.

When the blower switch is in 3 places, there is only 1 resistor in series in the circuit of the blower, and the blower operates at medium and high speeds. When the blower switch is in position 4, there is no series resistance in the circuit of the blower, and the blower operates at high speed. The difference between the motor blower and the air switch, turn on the fan blow switch) (that is, the air switch, if the temperature is the lowest temperature, then the temperature of the outside natural wind is the temperature of the external circulation, but it will be a little higher, because the empty external circulation switch air inlet is basically along the lower windshield and the nacelle, which will be reduced to the temperature of the engine compartment.

If it's an internal circulation, the temperature will be blown out of the car. If the temperature is high, the cooling water heat of the engine is regulated by the opening angle of the hot air natural air baffle in the evaporator (small tank radiator) in the air conditioning system. Because the entrance to the external circulation of the air conditioner is basically between the edge of the front glass and the engine compartment, the temperature will be carried into the engine compartment; If it is an internal circulation, it will blow out the temperature inside the car.

If high temperature is chosen, the heat of the engine cooling water is heated by the evaporator in the air conditioning system, and the air temperature is regulated by the opening angle of the natural wind zone.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The blower is a "fan" of the air conditioning system. The blower rotates through the impeller to suck the air inside or outside the car into the blower, and under the action of centrifugal force, it enters the air conditioning box. By changing the way the input voltage of the blower is delayed, the speed of the blower is changed, and the amount of air volume is changed.

It's normal to be loud, and there's no need to worry. The blower is an important electrical appliance in the air conditioning system, and the blower control circuit is to meet the needs of passengers for wind speed control.

If the temperature is the lowest, the fan is a fan of the air conditioning system. This fan sucks or expels air from the vehicle through engine rotation to enter the air conditioner under centrifugal force. It changes by changing the inlet voltage of the fan.

We must understand the car limb blower, because the car blower has abnormal noise in the air conditioning system of the automobile, and the abnormal noise outside the car is the compressor, and the blower inside the car.

And when the blower has a buzzing sound, sometimes the blower is not broken, it is caused by other reasons, but it plays a very important role in the broken car. It is the heart of the car's air conditioning system. Only then can the air conditioning system work properly.

Automatic fan resistors are an important part of automotive blowers. There are often failures in the market that cause the fan to run at high speeds, so that the governor module is replaced, but the fault persists. As a result, the pressure selection range is very wide, and the flow rate selection can be achieved by selecting the speed.

When the car air conditioner needs to be turned on and the fan continues to move at a constant rate, the fan operating point will move along the pressure and flow characteristic curves. The operating point of the fan during operation is not only determined by the sofa, but also the position of the blower. The fan is usually located under the dashboard in front of the passenger in the car.

Of course, there are models in the middle of the dashboard. Usually, the cabin air filter is close to the fan, away from the fan (air conditioner switch). If this temperature is selected as the lowest temperature, the external circulation is the temperature of the natural air outside the car, but slightly higher; The entrance to the air-conditioning circulation is basically on the north side of the front glass and engine compartment.
