Ten taboos on highway safety

With the increase of vehicles and the better repair of highways, the traffic flow on high speeds is also increasing, and the safety problems are becoming more and more serious. In order to allow the majority of drivers to travel safely, recently, after statistical analysis, the traffic police department released ten taboos for high-speed safe driving, reminding drivers and friends to pay attention to safe travel.

1. Avoid high speed driving

As we all know, highways have good road surfaces, and many drivers tend to drive fast as soon as they get on the highway, which is neither economical nor safe. Because the higher the vehicle speed, the greater the braking distance, the centrifugal force when the car turns is increased, and the steering stability of the car becomes worse. In addition, the faster the vehicle speed, the shorter the driver's line of sight and the narrower the field of view, and the resulting judgment errors increase. Therefore, controlling the driving speed is the primary condition for ensuring the safety of highway traffic.

2. Avoid speed driving

China's highways also have regulations on minimum speeds. During normal driving, the minimum speeds must not be less than 50km / h. Driving at low speed is easy to cause the trailing vehicles on the same lane to be compressed, which makes it impossible to increase the speed of the vehicle, and it cannot give full play to the fast and efficient advantages that the highway should have. . Of course, if you encounter severe weather such as high winds, you should slow down.

3. Avoid getting too close to the car

The safe driving distance should be changed according to the driving speed, weather and road conditions. The faster the speed, the greater the driving distance should be, especially in snow, rain, fog or road freezing.

4. Avoid illegal parking

When a car needs temporary parking for maintenance due to a malfunction, it must turn on the right turn signal in advance to leave the lane and stop in the emergency stop belt or on the right side of the road. If the car cannot leave the traffic lane due to faults, accidents, etc., it must immediately turn on the hazard warning flasher, and set a warning sign 100 meters behind the driving direction. At night, it must also turn on the wide and tail lights.

5. Avoid driving with faults

Because when driving on the highway, the technical status of the car is crucial. The consequences of traffic accidents due to steering, brake failure, tire puncture, etc. will be very serious.

6. Avoid going straight into the lane on the ramp

When entering the highway, you must increase the speed on the acceleration lane and turn on the left turn signal; when leaving the highway, you should enter the lane adjacent to the exit according to the exit notice sign and slow down. It is forbidden to turn on and off the lane directly on the ramp.

7. Avoid loading and driving according to regulations

If the vehicle is overloaded and driven at high speed on the highway, the inertia of the vehicle will increase, and the unsafe area for braking in an emergency will be extended. In addition, due to the increase in gravity, drag and friction caused by overload, leaf springs, half shafts and tire bolts are easily broken. Out of control, tipping or flat tire.

8. Avoid fog, snow, high-speed traffic

In heavy fog or snowy weather, it is best not to go on the highway, because it is easy to make the car slip, even if you want to go on the highway, you should slow down or pull away from the front and rear cars.

9. Avoid poor vehicle conditions on high speed

Some old cars with poor vehicle condition try not to go on the highway, and their speed is slow. In case of a breakdown of the car, it is easy to affect the driving of other vehicles.

10. Avoid fuel shortage on high speed

Some drivers are sloppy, not paying attention to the amount of fuel in the fuel tank, and hurried to the highway. Once the fuel is insufficient in the middle, there is no self-provided fuel on the car, and there is no gas station nearby, which easily affects the passage of other vehicles, so the high speed The road must have enough fuel.

The title of the Circular Pipe Fan

The circular Pipe Fan is an ideal ventilator with the perfect combination of performance and appearance. The clever cooperation between the newly designed chassis and the centrifugal impeller makes the gas hydromechanics reach the extreme, and its shape is small and very practical. With easy installation, light weight, low noise and so on. For the air, exhaust, return air and air purification to provide the source of power, high pressure can take tens of meters of pipe, a fan control multi-zone centralized ventilation, commonly used in real estate buildings, indoor ventilation Or pipe pressure. Circular duct fans can be the same size on both sides of the pipe, while the other side into the wind out of the wind

working principle

Circular duct blower with wing-shaped backward impeller, high-speed operation of gas hydrodynamics to the extreme, so the energy efficiency is very high, up to 70%, which means that with the smallest motor power delivery maximum wind power, which is normal Forward Centrifugal Fan can not achieve the effect. Therefore, both the fan duct energy-saving and strong winds. Ultra-high pressure can take tens of meters of pipe concentrate ventilation, the main characteristic of the pipeline fan is the pressure. Replace the traditional ventilation equipment. Fan vibration-free, dynamic balance of less than 0.17g, only the standard value to ensure the superior quality fan, imported metal impeller or PP plastic perforated in accordance with the wing, which is characterized by strong rigidity, high temperature, environmental protection, air volume Large, but also to a certain extent reduce the noise.

Round tube fan core with an external rotor motor, its life depends on the bearing, the motor uses imported single deep groove ball bearings, external rotor motor compact structure, small size, energy efficient, pure imported bearings, 120 ℃ automatic parking hot Protection, high-quality copper winding and so on. 24h continuous operation can be more than 30,000 hours.


About noise

Motor does not make any sound, the fan is mainly air flow sound, because the impeller speed is high 2500 rpm, resulting in high pressure air volume is high, so you can take a long pipe with the same and to ensure that does not affect the air flow. If you use it when you sleep at night, it is certainly noisy. However, you can reduce the speed to reduce the noise, it is to ensure that there is sufficient air volume to reduce the speed.
