This country\\ s first specific xenon lamp, \"the traffic control provisions introduced led to much controversy

Xenon lamp in Wuhan City, the night will be regarded as \"not required the use of light, the traffic control department will be violations of human is liable to a fine of 50 yuan, denoted by 1 point deduction (with map)

In recent years, a greatly improved driving the lighting brightness of the xenon lamp technology is more widely used in automotive lighting. However, due to the non-standard installation, the advanced automotive lighting technology, but often the chief culprit in the manufacture of road \"light pollution\" has become a thorny management problems of the traffic control department.

In early December, the traffic control department of Wuhan City: night xenon lamp as the \"light\" does not require the use of illegal acts will be punished by a fine of 50 yuan, note the buckle punishment. The country\\ s first specific xenon lamp, \"the traffic control provisions introduced, caused much controversy in the community immediately.

Status quo

Lights at night R \"light\" \"light pollution\" into a traffic nuisance

Lee, who lives in the Dongting district of Wuhan City, recently discovered that their headlights at night seems to have suddenly dark a lot, opposite the car lights a dozen, and he did not see the road. Lee drove to a car repair shop before understood why: So many people put on the car a very high brightness xenon lamp.

Converted lights to seek psychological balance owners

Lee to consider a long time, the decision to dress for their own car xenon lamp. He told reporters, after driving at night, opposite the strong light, and also refused to yield to open the strong light. Although the collision of two beams of light, road conditions or difficult to see, but the psychological balance of many.

Lee\\ s ideas represent a majority of the modified headlights owners mentality. In recent years, with the growing number of private cars, the headlight conversion has become an automotive beauty shop and repair shop for new business projects. Wuhan City, North Road, a car repair shop owner told reporters that the modified lights most of the 15 million private cars, this car headlight brightness is relatively weak, unlike those high-end car lights discerning, driving at night will not be able to resist a shot to the glare of the opposite vehicle.

Conversion lights for the night, speeding

The owners told reporters that a moving car \"eye surgery\", he converted lights for night speeding. Before lights even at night with high beam, the vision, but 50 meters, but now he loaded his car Philip \"Silver Warrior\" light bulb, you can see the road far twice.

However, unauthorized alterations of the xenon headlights to pedestrians and other vehicles is a security threat. Who lives in the Wuchang Dong Wu Road, the Mr. Guo to cross the road at night, often run into the face of driving the vehicles of the xenon headlights, the front of a white, see nothing, several times, almost in a car accident.

Xenon lamp brightness is three times higher than the general halogen bulbs

Wuhan Environmental Protection Bureau experts said that the brightness of the xenon lamp is three times higher than the general halogen bulbs, and light color close to the color of sunlight at noon. Night driving across the car continued to open the xenon lamp direct the brightness of the moment is sufficient to produce visual \"blind spot\" in front of vehicles and pedestrians can easily lead to accidents, thus creating a typical \"light pollution\".

Question

\"Forbidden xenon Order:

Management How can the unworthy?

In early December, Wuhan City, the traffic control department announced: the use value of the xenon lamp over the operation of motor vehicles safety conditions (GB7258-2004) on the headlamp beam luminous intensity of the minimum of standards, therefore, to use at night in Wuhan City The xenon lamp will be treated as \"do not require the use of lighting, traffic control department will be violations of the person liable to a fine of 50 yuan, remember to subtract 1 point.

Unauthorized installation of xenon lamp will be punished

Provisions introduced, which in many motorists immediately controversial. Some high-end car drivers in the offing: own vehicle at the time of purchase had been equipped with xenon lamp, and now we going to forcibly removed? Could that be the product failure of car manufacturers? In this regard, the Traffic Management Bureau of Wuhan City public clarification: condenser role due to the high-end vehicles original xenon lamp with a lens will produce injection light does not diverge interference on a vehicle in, therefore, only the unauthorized installation of xenon light before will be penalized.

A political and legal departments in Hubei Province, Chen bluntly: \"The original intention of the traffic control department of the introduction of punishment policy is good, but the state does not develop the highest standards and restrictions on the brightness of the vehicle headlamps. Luminous intensity of the minimum standards, penalties luminous intensity value is too high xenon lamp, so the basis for punishment can not be convincing to the public. Meanwhile, the state is a unified management standards of the vehicle lights, since to allow manufacturers to install the xenon lamp, then the personal conversion of headlamps to meet the national standard. Why must we be punished? enforcement of such a distinction is contrary to the rule of law spirit. \"

The relevant provisions did not make provisions for the maximum illumination level

Reporters access to the traffic control department of Wuhan City, the reference to \"the operation of motor vehicles safety conditions (GB7258-2004), discovered which part on the lights, power, minimum lighting levels, color and illumination angle provides does not the provisions of the largest lighting brightness.

Xenon lamp caused controversy in the final analysis is the contradiction between the advanced and backward management

Hubei Academy of Social Sciences Feng Guilin researchers and other experts said, the xenon lamp caused controversy in the final analysis, the contradiction between the advanced and backward management. How to guide people in science, standardized use of the xenon lamp technology, is the traffic management department shall make efforts to solve problems.

Experts believe that, fundamentally solve the traffic light pollution \"problem, the traffic control department should increase the penalties for\" abuse of light behavior; business and other related departments should increase automotive beauty salons and repair shop, put an end to unreasonable transformation of the source; the same time, the whole community should strengthen the driving moral education. Simple implementation of the \"forbidden xenon Order one size fits all management, not only a temporary solution, may also fall into unworthy errors.

Expert

Xenon lamp this wrong is converted to blame

A senior car modification experts told reporters that the xenon lamp as an advanced automotive equipment and technology in the international community has long been widely used in the country to promote the general trend. Xenon lamps can enhance driving safety and comfort, to help alleviate tension and fatigue of people traveling at night, helping to drive the first time found dangerous, in large part to reduce traffic accidents at night.

For the modified xenon lamp acts harm to traffic safety, the expert said, some owners simply the pursuit of the size of the high-brightness, optional xenon bulbs and halogen bulbs, different size, light-emitting part of the deviation from the focus position lights, so there is no condenser, the right beam of serious negative effects, thus affecting the opposite pedestrian and vehicle safety. Some modification operations changes to the original car circuit, can easily lead to overload short circuit fire, and may even lead to accidents such as car ignition.

It is understood that the private car headlight modification does not affect the automotive appearance, the state does not enforce the provisions of approval, plus some owners in the annual examination before the lights will change back to the original vehicle annual examination can not be this limit. Converted lights has become a major problem in traffic management.

The number of car modification companies and the driver said in an interview with reporters, the real harm caused by the road \"light pollution\", xenon lamps, non-standard installation and improper flashing lights, and secretly increased the lighting angle and lack of driving considerate behavior of light abuse. Even the traditional halogen lamps, such random abuse is also very dangerous. Therefore, the \"light pollution\" and the xenon lamp is not directly linked.

12 analyzed the development trend of imports of pneumatic tools

Web Design And Seo For www.china-webdesign.com
Gas Cooker valve – China Manufacturer
Thank you for inquiry my Gas Cooker valve, Tel: 086-0574-86196509, E-mail: chairman@nbqianshou.com
http://www.qus-gasvalve.com/key-Gas-Cooker-valve-34/

  With the continuous improvement of production and degree of automation, imported pneumatic tool technology surface rapidly expanding the variety of products continued to increase, performance, quality, continuous improvement, steady growth of the market sales value. The development trend of pneumatic products in the following areas:

    A small, integrated

    Limited space requirements for the form factor of the pneumatic components as small as possible, the miniaturization of the major trends. Minimum cylinder bore of only f2.5, and the preparation of the switch; solenoid valve width of only 10mm, the effective cross-sectional area of ??5 mm2; interface f4 pressure reducing valve has been developed. According to the survey, the demand for miniaturization of components, approximately doubling every five years.

    Valve integrated not only together a few valve installed, and also includes features such as sensors, programmable logic controller. Integrated not only save space, as well as conducive to the installation, maintenance and reliability.

    Second, the precision

    In order to more accurate positioning of the cylinder, the use of the sensor, the proportional valve to achieve the feedback control, the positioning accuracy of 0.01mm.

    Also developed the cylinder precision 0.3mm / s, low speed cylinders, and 0.01N small load cylinder.

    Air source treatment, filtration accuracy of 0.01mm, the filtration efficiency of 99.9999% of the filter and sensitivity 0.001MPa pressure reducing valve has been developed.

    Third, the combination, intelligence

    Import pneumatic tool component combination with valve, with a switch cylinder. Has been used in material handling, cylinder, swing cylinder, combination of pneumatic chuck and vacuum suction; a mobile combination of small items, will take the director\\ s two cylinder combination of X and Y axes made, comes with the solenoid valve, the control box, compact, small footprint, adjustable stroke.

    Japanese fine (strain) the development of the smart valve with sensors and logic circuits, pneumatic and combination of photovoltaic technology. No external actuator can be directly read the sensor signals, by the logic circuit judge to decide the smart valve and subsequent implementation of the components.

    Development of functional modules has a history of more than ten years, and now continue to improve. These common module can be a combination of several programs in order to achieve different mechanical functions, economic, practical and convenient.

    Fourth, high-speed

    In order to improve productivity, automated tempo is accelerated, high-speed is an inevitable trend.

    At present, the cylinder piston speed range of 50-750mm / s. Requirements of the cylinder piston speed is increased to 5 m / s up to 10m / s. According to the survey, after five years, the speed of 2-5m / s, and the cylinder demand will increase 2.5 times, more than 5 m / s cylinder demand will increase by 3 times. Accordingly, the response speed of the valve will speed up the requirements by 1/100 second to 1/1000 second.

    Fifth, the high life, high reliability and self-diagnostic function

    50 million times the life of the valve and the the 3000km cylinder has the commercialization of a high frequency valve life requires more than 100 million times $ 200 million, the best in textile machinery. This requirement, the elastic sealing valve is difficult to achieve, which makes the gap sealing element to regain attention. Numatics, United States (Numatics) a valve clearance seal, ventilation after the spool in the valve body in suspension status, the formation of friction-free movement, since the dust-proof function, the life of the valve can be more than 200 million times Although this is an old product is still worth learning.

    The components are mostly used for automatic production line, component failures tend to affect a full range of operation, production line suddenly stopped, the serious damage caused by the high demand, for which the reliability of pneumatic components. A chemical fiber company absolutely reliable supply of pneumatic components in the set life to maturity regardless of whether they can continue to use, to replace them all. Here the balance of the various component life, the so-called, etc. Life Design. Sometimes, in order to ensure reliable operation, had to sacrifice life indicators, therefore, the pneumatic system of self-diagnostic features mentioned on the agenda, additional life expectancy and other self-diagnosis function of components and systems being developed.

    Not only increases with the multifunctional mechanical devices, more and more the amount of wiring, installation, maintenance workload, but also prone to failure, affect their reliability, the improvement of the wiring system for pneumatic components and systems designers of the pie.

Sixth, mechatronics

    In order to accurately pre-set control target (such as switches, speed, output power, position, etc.) should be used the closed-loop feedback control mode. Gas – between the electrical signal conversion, became the key to achieve closed-loop control, the proportional control valve can become the interface of such a conversion. The development of various forms of proportional control valve and electric – gas ratio for a long period of time / servo system and its performance, reliable, cheap air technology development is a major issue.

    Now has a lot of application examples of the proportional / servo system, such as the precise positioning of the cylinder; for the vehicle suspension system to achieve good damping properties; cable car turn automatically when you tilt the device; to serve the patient\\ s robot. The above examples are more practical and more economical to be further improved.

    Seven oil-free, odorless, sterile

    Humanity\\ s increasingly high demand for oil-free lubrication of pneumatic components popularization. Some special industries, such as food, beverage, pharmaceutical, electronics and other more stringent requirements on the air, with the exception of oil-free, also requires odorless, sterile, and special requirements such as the filter will be developed.

    Application of new technologies, new processes, new materials

    Profile extrusion, casting infiltration, and module assembly technology a decade ago has been widely applied in the country; die-casting of new technologies (hydraulic core pulling, vacuum die-casting, etc.), deburring new technology (explosion, electrolysis, etc.) in the domestic gradually be extended; piezoelectric technology, the bus technology, the new soft magnetic materials, the dialysis membrane being applied; superfinishing, nanotechnology will be transplanted.

    Particularly concerned about the scientific and technical personnel of the air industry seals the development of new trends, once the new structures and new materials, seals, and will be adopted.

    Nine, to meet the special requirements of certain industries

    Special pneumatic components is an important aspect of opening up markets in the fierce market competition, developed for the specific requirements of certain industries, the plants are very concerned about. Recently developed by the domestic air industry such as Chalco special cylinder (high temperature, self-locking), special railway cylinder (earthquake, high reliability), the tracks lubrication valve (anti-low temperature, filtering capabilities), the environmentally friendly automobile fuel systems ( multi-media, excellent).

    X., energy saving, environmental protection, low-power

    Energy conservation is a permanent issue, and provides for the establishment of ISO14000 environmental protection system standard. Pneumatic components of the low-power not only for energy saving, it is more important is the combination with microelectronics technology. Power consumption of 0.5W solenoid valve has long been commercialized, 0.4W, 0.3W valve has been developed by the PC direct control.

    XI standardization

    Implement the standards, especially ISO international standards companies must comply with the principle. There are two aspects of the work to be done: the first pneumatic products should carry with pneumatic relevant existing standards, such as terminology, technical parameters, test methods, installation size and safety indicators. Enterprises should establish standards for assurance system, 3: quality (ISO 9000), environmental (ISO 14000) and safety (the ISO18000).

    Standards continue to add and amend the company and its products will follow sustainable development and updates, the only way to promote the steady development of pneumatic technology.

    12, safety of

    From the recent promulgation of the pneumatic ISO international standards shows that the very strict requirements on imports of pneumatic tools, components and systems security. ISO4414 pneumatic General Principles in the element of risk is divided into 14 categories, mechanical strength, electrical, noise, out of control. ISO International Organization issued ISO18000 standard requires enterprises to establish a safety assurance system, and security issues particularly important on the agenda. To this end, the product development and system design to seriously consider the safety index is the general trend of aerodynamic technology development. Domestic enterprises, the industry standard in the past neglect of safety issues, the need for re-examination of the products have been put into the market and correction.

The need for frequent use to strengthen conservation in order to maintain its good technical condition. Inside and outside the door frame. Forklift lifting system between the main components are the relative motion. Inside and outside the door frame composed of a kinematic pair, fork frame and door frame composed of a deputy campaign. In order to improve the accuracy of the movement of the deputy campaign, to reduce friction between moving structures, to reduce vibration and noise, and improve the lateral stability of the fork unloading goods vehicle, inside and outside of the door frame and fork rack side of the wheel are adjusted gasket.
Each conservation deal with inside and outside the door frame channel and on the chain sprocket lubrication in order to ensure good lubrication, reducing friction deputy campaign. In the wide field of vision lifting system, two lifting cylinder stroke should be equal to the respective inlet piping should be smooth. The two fuel tanks of the piston rod end with the door frame, sprocket bracket contact. Fork of the hinged type, fork frame made of slider-style fork built around two circular shaft, each root of the round sleeve on a Fork, Fork in the round shaft slide to adjust the two Fork spacing, assembly and disassembly of the fork, round shaft removed, fork latch in the circular axis positioning. Fork. Forklift installation should pay attention to matching. The pairing of the two goods cross on thick, fork length should be approximately equal. The angle between the two forks of the vertical section and horizontal section should also be consistent, fork mounted on the fork frame, the plane on the two forks should be kept in the same plane should not have the level of dislocation.

   North America is the largest region of the world WPC market. U.S. Pricipia Partners consulting firm pointed out that the only North American market, the amount of 2001 reached 320,000 tons, is expected to increment the year 2005 demand will be double-digit rate, the amount of 2005 than in 2001 doubled, which decking

(Including more than 60 percent of the platform, the board, site, plate) the amount of the total amount of the. In addition to the decking outside, as well as wainscoting, ceilings, decorative panels, running boards, siding, highway noise clapboard, seaside flooring, building templates, moisture-proof board can use wood composites sheet. In addition,

Can also be used for decorative borders, fences and garden handrails, packaging pallets and combo pallets, and furniture (including outdoor tables and chairs), the ship cockpit partition, office partitions, storage boxes, flower boxes, active frame, Phi stack board, one hundred windows.
Strandex pointed out that the WPC is environmentally friendly materials, even though Europe, the amount of small, but because the processing plants to worry about the European Community will be the form of regulations to effectively limit use of PVC, plastic wood composite  window frames replace PVC window frames huge markets and opportunities. So some people think

Alternative to PVC and other plastic products, wpc wood products, plastic products as before, substitute wood products – rapid growth.
In short, the WPC is a promising environment-friendly materials, processing technology has matured and diversified
