How to deliver refrigerated trucks in fog days

In recent years, the air pollution has been severe. The haze situation has become severe day by day. Sometimes visibility is less than one meter. This has brought troubles to the distribution of refrigerated trucks. What should be noted about how to open a refrigerated truck in fog and haze? Xiao Bian today discussed this issue with you and gave them to the refrigerated vehicle families:

   When opening a refrigerated truck in fog, it is necessary to turn on the low beam and fog lamps both in the dark and during the day. This can increase the visual distance on the one hand, and on the other hand, the headlights can be turned on when the current car changes lanes. The attention of the car ahead. If you are driving on a freeway, you need to turn on the marker lights, front and rear lights, and hazard warning flash lights.

It should be reminded that it is best not to use high beam lights in rain and fog, because the beam angle of high beam light can easily cause large scattering of light, and the worst penetration is in fog days. Try not to open windows when driving in fog. Ventilation, can open the car cycle and air filtration system, use a car air purifier, try not to smoke in the car.

In the event of high-speed traffic in the event of heavy fog, "cluster fog" weather, we must strictly control the speed and maintain the distance. When the visibility is less than 200 meters and more than 100 meters , the hourly speed does not exceed 60 kilometers. When the visibility is less than 100 meters and more than 50 meters , the speed does not exceed 40 kilometers per hour .

Smoggy weather is bad sight   Do not blindly overtake, safety principle one: the correct use of lighting; safety principle two: keep a relatively low speed; safety principle three: use a horn to prompt; safety principle four: do not blindly overtake, pay attention to the pedestrian pavement; safety principle five: do not Meng Step on the brakes; safety principle 6: Two lanes are selected on the outside, and three lanes are selected; Safety Principle 7: In case of emergency, double flashing must be turned on and a warning sign must be set up.

In addition, the next fog of weather to open the refrigerated truck must be careful not to slam on the brakes, one is the general road slippery and slammed on the brakes will be the car out of control caused the accident, and second, fog visibility is easy to make the brakes on the low fierce The phenomenon of rear-end car rear-end caused an accident. There is not to blindly change lanes to avoid accidents.

Box Guideway Machining Centers

Box guideway machining center also call hard rail machining center in China, it refers to a casting part where the guide rail and the bed are integrated, and then the guide rail is processed on the basis of the casting, which is a type of hard guide rail. The shape of the guide rail is cast on the bed, and then processed into a guide rail through quenching and grinding. The hard rail used in the hard rail machining center is generally a rectangular structure, commonly known as a rectangular guide rail or box guide rail. The Box way machining center machining center adopts sliding friction, which leads to a larger contact surface and high rigidity and strength. Therefore, the box guideway machining center is more suitable for heavy-duty cutting and is suitable for heavy-duty mold processing.

Advantages of box guideway Machining Centers:
1. Able to withstand larger loads, suitable for rough machining machines with large cutting amounts and large feed rates.
2. Due to the large contact area of the guide rail, the machine tool operates more smoothly, making it suitable for factories with high requirements for machine tool vibration.
Disadvantages of box guideway machining centers:
1. Shorter service life. Under the same maintenance and usage conditions, the service life of box guideways is generally shorter than linear guide machining center, because box guideways operate with sliding friction, while linear guide operate with rolling friction, resulting in greater wear and tear.
2. The repair cost is too high. The maintenance of box guideway machining center is much more difficult and costly than linear guideway machining center. If there is insufficient scraping allowance, it may involve disassembling all the large parts of the machine tool, performing quenching and mechanical processing again, and even more importantly, recasting the large parts. The wire gauge only needs to replace the corresponding linear guide, which will not greatly affect the use of related large parts.
3. The running speed of machine is low, and box guideways machining center usually cannot withstand too fast running speed due to their movement mode and the excessive friction they bear, which contradicts the current machining concept to a certain extent. Especially many factory workers do not have the corresponding maintenance knowledge for machine tools. Many times, they only know how to use the machine tool, but largely neglect the maintenance of the machine tool. The maintenance of the machine tool track is of utmost importance. Once the lubrication of the track is insufficient, it can cause the track to burn or wear excessively, which is fatal to the accuracy of the machine tool.
