What is the role of the positioning light?
Positioning lights, also known as position lights, car width lights are also commonly known as small lights, the purpose is to allow the locomotive to be in the dark and dark days, other passers-by can judge the size and position of the vehicle. The car part has mandatory provisions for positioning lights on the left and right sides to indicate the width of the car. Motorcycles are either left-right symmetrical or central single-position lights.
Positioning lights in the locomotive regulations are more flexible, both sides or single lamp design can be
For a round lamp design like the SV650, some will design the positioning light inside the headlights, and the small light bulb below will be the light bulb for the positioning lights.
Is it only possible to drive the positioning lights at night?
The brightness of the positioning light is low, it is almost invisible during the day, and the viewing distance is limited at night. More importantly, the brightness of the positioning light cannot illuminate the road ahead, and you cannot ride normally.
The headlights are on, do you still need a positioning light?
When the headlights are turned on, the function of the positioning light is replaced by the headlights, and there is no need for a positioning light. However, the headlights consume a lot of power, so many locomotives will only light up the positioning lights after power-on (for example, F800R: a total of 3 bulbs for small and small eyes, small eyes are separate high-beam lights; large eyes include positioning lights, low beam lights After the power is turned on, the positioning light is turned on, the engine is turned on to the low beam light, the handle is controlled to control the other big eye to light the high beam light, and the headlight is turned on after the engine is started. In the locomotive design, the positioning lamp is shaped. Can also become one of the features.
BMW's classic size eyes actually have three "eyes", and the small eyes are high beam lights~
The headlights are turned on, and the function of the positioning lights has actually fallen.
VJR's V-shaped positioning lights become the style's features
What is the role of daytime running lights (DRL)?
As studies by the traffic control departments of various countries have shown that turning on the lights during the day can improve visibility and reduce accidents, there is a mandatory requirement for daytime running lights. Some national regulations require that if the daytime running lights are not designed, the low beam can be forced to be replaced, which is why the imported cars that we ride cannot turn off the lights. It is a pity that there is no such law in China that is mandatory for motorcycles. Most of the passing locomotives have a light switch. They can be turned off instead of always on. In actual riding: it is dark, dim, dim, and dim under the overpass. In the darkness of the cave, I hope that you will develop good safety habits and keep the lights on. Many bad bulbs are not smashed. It is much worse than being replaced by a light bulb!
X Diavel S's daytime running lights are highly recognizable even in the case of some backlighting of the sun.
Are the LED lights other than the headlights daytime running lights?
Because of the high brightness of the LED, it is a common light source for daytime running lights, but the LED is not necessarily a daytime running light. As long as the brightness does not meet the requirements, it can only be called a positioning light.
Do you need a constant day low beam group for daytime running lights?
No, the daytime running lights can be replaced by a constant light group. The best example is DUCATI's recent use of DRL models, such as SuperSport full car, X Diavel S, etc.: Because of the special daytime running lights, it is generally brighter than other lights. The locomotive, SuperSport and X Diavel S's low beam lights can be turned off.
Can I only drive daytime running lights when I ride at night?
Although the daytime running lights have high brightness, there is no light distribution requirement for low beam lights, and daytime running lights cannot produce an effective light pattern to illuminate the road surface. With daytime running lights, other passers-by and vehicles can see you, but you can't see the way!
There are many kinds of pneumatic pipes, which are generally produced with PU raw materials, with stable quality, high pressure resistance, weather resistance, wear resistance, zigzag resistance, smooth and flexible pipe body, bright color, high elasticity, winding resistance and small bending radius.
The tube body is smooth and flexible, bright color, high elasticity, winding resistance and small bending radius. Temperature range: - 15 - + 70 ℃.
Product classification
1. Pu pneumatic pipe
2. Pu (polyether) pneumatic pipe
3. Pu (polyurethane) bobbin
4. Pu (polyether) bobbin
difference:
Polyurethane pneumatic pipe is over air type. If it is used for over water, its service life will be affected,
Polyether pneumatic pipe can pass air or water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic pipe.
The bobbin is wrapped with a layer of fiber in the middle of the common pneumatic pipe. Therefore, the bobbin is more solid, pressure resistant and non explosive than the common pneumatic pipe.
Product selection
What should be considered when choosing the type of plastics for blow molding pneumatic pipe?
The following aspects should be considered in the selection of pneumatic pipe materials.
Whether the wall thickness of the welded blank of the pneumatic pipe can be kept uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic pipe is bright, whether the demoulding is easy, and whether the strength can meet the requirements, etc.
Performance comparison of plastics for blow molding pneumatic pipe. The pneumatic tube formed by blow molding is in thermoelastic state, and its density is smaller than that after cooling and shaping, resulting in shrinkage. For the general size of pneumatic pipe is not strict, forming shrinkage has little effect. But for the pneumatic pipes of specified size, such as some hoses used in precision machines, large shrinkage has a considerable impact. The larger the blowing volume is, the more significant the effect is.
The advantages of extruding and blowing plastic forming pneumatic pipe are less investment in production equipment, simple equipment structure, easy mold manufacturing, high forming of pneumatic pipe during production, uniform temperature control, and various specifications of pneumatic pipe can be formed. The disadvantage is that the wall thickness uniformity of pneumatic pipe is poor.
The advantages of injection blow molding pneumatic pipe are that the plastic pneumatic pipe has good product quality, accurate dimensions, no seams, uniform wall thickness, multi-mode molding production, high degree of automation, which is very suitable for large-scale high-efficiency production of small specifications. The disadvantage is that the investment of equipment and molding die is large, and the operation and production need skilled workers.

Tips for pneumatic pipe
Polyurethane pneumatic hose is suitable for compressed air, ordinary industrial water and non corrosive oil. In order to maintain a long service life, it must be used under rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly. If it exceeds the limit, the hose may break. If the fluid temperature is too high or the fluid is corrosive, the hose may break. If the working environment temperature is too high or there is chemical gas in the working space, the hose may crack. If the hose is stored in a wet place or the storage period is too long, the hose may hydrolyze or age, which may lead to fracture
