Antifreeze should generally be replaced every two years or 40,000 kilometers. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold winter parking. Its full name is antifreeze coolant. Many people think antifreeze is only used in winter, but in fact, it is required year-round. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. Corrosion prevention function: The engine and its cooling system are made of metals such as copper, iron, aluminum, steel, and solder. Over time, these metals can corrode and rust when exposed to water under high temperatures. Antifreeze not only avoids causing corrosion to the engine cooling system but also provides anti-corrosion and rust removal functions.

What is the reason for the weak lifting and walking of the ShanGong 50F-2 boom?

The possible reasons include decreased volumetric efficiency of the tandem pump, blocked feedback oil pipe, or operating system failure. Decreased volumetric efficiency of the tandem pump: If there is a noticeable change in throttle size, it is generally due to decreased volumetric efficiency of the tandem pump, and the tandem pump needs to be replaced. Otherwise, check whether the priority valve spool is worn or stuck. If worn, it needs to be replaced; if stuck, it needs to be cleaned. If none of the above conditions are present, check whether the steering feedback oil pipe is blocked. If not blocked, turn the steering wheel after stopping. If it is difficult to turn, it indicates that the steering gear and steering cylinder are normal. Otherwise, the fault may lie in the steering gear or steering cylinder. Such faults must be analyzed and judged by professional maintenance personnel based on the on-site situation. Operating system failure: The ShanGong 50F first goes to the operating system, so first check whether the bucket operates normally. If everything is normal, it indicates that the pilot oil circuit is normal, and the working hydraulic system oil circuit is normal. Then, swap the pilot control oil pipes of the bucket and boom. If the boom returns to normal after swapping, it indicates that the working hydraulic system of the boom is normal, and the problem lies in the stuck or severely worn proportional distribution valve in the pilot valve. The pilot control valve needs to be replaced. Otherwise, the fault lies in the multi-way distribution valve and boom cylinder, and professional personnel are required to diagnose and repair on-site.

How many points are deducted for turning over double solid yellow lines?

Turning over double solid yellow lines results in a deduction of 3 points. New Traffic Law: According to the new traffic law, accidentally crossing double yellow lines when making a left turn at a traffic light intersection will result in a fine of 200 yuan and a deduction of 3 points. Double Yellow Lines: Double yellow lines are a professional term commonly used to describe traffic markings. Yellow lines refer to both single and double yellow lines. When driving on the road, you will notice yellow lines painted in the middle of the road, acting like a divider to separate traffic moving in opposite directions. Double yellow lines consist of two parallel solid yellow lines, usually painted in the center of the road as ground markings. If one of the lines is solid and the other is dashed, vehicles may cross from the dashed side under safe conditions, such as for overtaking or making a U-turn. However, double yellow lines should not be casually crossed. At intersections with traffic lights, double solid yellow lines are typically painted on the ground in left-turn lanes. Vehicles making a left turn when the traffic light permits must not cross these double yellow lines. Accidentally crossing double yellow lines during a left turn will be automatically captured by traffic cameras as a violation. If traffic police are on duty at the time, they may also manually record the violation and issue an on-the-spot fine. Crossing solid yellow lines during a left turn at a traffic light is considered driving outside the designated lane and is subject to a fine of 200 yuan and a deduction of 3 points from the driver's license.
