After two years of spurt growth, the auto market has calmed down this year. The concept of people buying cars and cars becomes more rational. According to the latest survey by authoritative organizations, in the most concerned car properties, safety has surpassed the traditional focus of car purchase and car use such as power and appearance, and has risen to the top with the price.
High-strength compartment structures, bumpers, body steel plate thickness, and the number of airbags can minimize damage when a vehicle accident occurs. ABS anti-lock braking, brake force distribution (EBD, etc.), brake assist (EBA, etc.), traction control (ASR, etc.), and body stability control (ESP, etc.) These active safety features have become the focus of the car's attention. However, when people pay attention to these vehicle safety equipment, they may overlook the role of car lighting in safety.
Many people seem to have only noticed the decorative and fashionable features of the lights, and even more, they read the lights with the view that the lights can be on. They ignored the great effect of the lights on safe driving. According to data from Osram, a German lighting expert, 60% of traffic accidents occur at night, and 22% of traffic accidents occur when the driver's eyes are unclear. It should be noted that car lighting plays a very active role in driving safety. Its mission is to prevent accidents and allow you to see hidden accidents during the night to avoid traffic accidents. Therefore, whether the vehicle has a good lighting effect should also be a part of our concern about the safety performance of the vehicle.
In terms of buying lights, OSRAM proposed some options for the car lights for your reference. The most important point is: try to choose the original lights, that is, what brand your car is designed to leave the factory. The headlights, then try to choose the same brand of headlights when updating. In this way, there is no problem in matching, and more importantly, quality will be guaranteed. In addition to joint venture products, there are also products without licenses and small workshops. Different grades of products are almost the same from the outside, but the market price is not a small gap, the quality is uneven, ordinary consumers find it difficult to see the mystery. However, it is not difficult for inexperienced people to see that the positioning of the filaments of counterfeit and substandard headlights is inaccurate, resulting in very uneven light, which is relatively scattered, or very dazzling. This not only causes the driver's line of sight to be unclear in the course of driving, it is unable to see the situation of the road in time, and the glare at night when the car will make the opposite driver visually blind, often becomes a traffic accident.
In addition, most drivers will only replace the lamp bulb when it is broken. Actually, the brightness of the car lamp will decay with the increase of the service life. If the lamp is not replaced when it is not suitable, the risk of accident will be closer to us. Therefore, once it is found that the lighting can no longer meet the driving needs, we must take the initiative to replace the automotive light bulbs to ensure driving safety. Only car lights that are more distant and clear can help drivers find safety hazards in time and take measures to bring a safer and more comfortable driving experience.
Ultrasonic Drilling Rig For Geological Survey Investigation
Sonic drilling is a soil penetration technique that strongly reduces friction on the drill string and drill bit due to liquefaction, inertia effects and temporary reduction of porosity of the soil. The combination makes penetrating for a large range of soils easy for our Sonic rigs and tooling. The penetration rates in most bedrock are faster with this technology also.
At first glance, a SONIC drilling rig looks very much like a conventional air or mud rotary drill rig. The biggest difference is in the drill head, which is slightly larger than a standard rotary head. The head contains the mechanism necessary for rotary motion, as well as an oscillator, which causes a high frequency force to be superimposed on the drill string. The drill bit is physically vibrating up and down in addition to being pushed down and rotated. These three combined forces allow drilling -to proceed rapidly through most geological formations including most types of rock.
In overburden, the vibratory action causes the surrounding soil particles to fluidize, thereby allowing effortless penetration. In rock, the drill bit causes fractures at the rock face, creating rock dust and small rock particles, which facilitates advancement of the drill bit. In many instances the drilling and coring of rock and earth can be accomplished without the use of any drilling fluid whatsoever. This is an important requirement for environmental drilling projects. Compressed air, drill mud, or plain water can be utilized to remove the cuttings and speed up the operation further, depending on the application that the machine is used for.
The oscillator is driven by a hydraulic motor and uses out of balance weights to generate high sinusoidal forces that are transmitted to the drill bit. An air spring is also incorporated in order to confine the alternating forces to the drill string. The frequency can be varied to suit operation conditions and is generally between 50 and 160 hertz (cycles per second). As a comparison, ordinary household current in many countries alternates at 60 hertz. This frequency range falls within the lower range of sound vibrations that the human ear is capable of hearing.
While the principle behind the SONIC drill rig appears complicated, the machine is actually very simple to operate. The driller only adds vibratory energy to the normal rotary motion. He simply chooses a frequency that gives him the best drilling rate or best core recovery, as the case may be.
