Mechanical oil and hydraulic oil differ in the following aspects: 1. Different compositions: Mechanical oil is processed from base oil, antioxidants, etc.; Hydraulic oil is processed from base oil, antioxidants, anti-wear agents, anti-foaming agents, etc. 2. Different uses: Mechanical oil is mainly used for lubrication in relatively precise equipment; Hydraulic oil is mainly used for transmitting hydraulic power in hydraulic equipment. Mechanical oil is obtained by dewaxing, solvent refining, and clay treatment of petroleum lubricating oil fractions. It is divided into high-speed mechanical oil and ordinary mechanical oil, which are used for lubrication of textile machinery spindles, ordinary machine tools, and other machinery, respectively. Hydraulic oil is a hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays roles in energy transmission, wear resistance, system lubrication, anti-corrosion, rust prevention, cooling, etc., within hydraulic systems.

How to Defog a Car on Rainy Days?

Methods to defog a car on rainy days: 1. Turn on the front window defogging mode, increase the fan speed, turn on the temperature switch, and lower the temperature; 2. Activate the one-touch defogging function; 3. Open the windows to increase air convection, reduce the temperature difference between inside and outside the car, and weaken the conditions for fog formation; 4. Spray defogging agent evenly on the glass surface and wipe it clean with a dry towel; 5. Make a DIY defogging agent with dish soap and spray and wipe it before driving. The reasons for fog on car windows are: 1. The temperature of the car glass is lower than the dew point temperature; 2. The temperature difference between inside and outside the car is large. The functions of car windows are: 1. Shelter from wind and rain, sound insulation and noise reduction; 2. Reduce wind resistance and guide airflow; 3. Protect the personal safety of passengers in the car.

What are the methods for taking the Subject 2 driving test on a rainy day?

Subject 2 rainy day test methods: 1. Choose shoes: Prepare in advance by selecting shoes with soles that have good friction to avoid slipping when stepping on the accelerator or clutch. 2. Clear rainwater from mirrors: The biggest impact of rain on the driving test is obstructed vision, and you are not allowed to stick your head out to observe during the test. Therefore, before starting the test, clear the rainwater from the rearview mirrors to ensure clear visibility. 3. Leave a gap in the window: On rainy days, the car can easily fog up when closed, so do not close the window completely during the test; leave a small gap for ventilation. 4. Use windshield wipers: Adjust the speed of the wipers according to the intensity of the rain. The purpose of these measures is to ensure clear visibility. 5. Maintain steady speed: The goal of taking the test is to pass, but safety is a necessary prerequisite. Therefore, during rainy day tests, it is essential to control your speed and maintain a safe distance from other vehicles to avoid excessive speed or following too closely.

Why Do Dash Cam Memory Cards Frequently Get Damaged?

The frequent damage to dash cam memory cards is mainly due to two reasons. Below is a detailed explanation of the common causes of memory card damage: 1. Poor quality of the memory card. 2. Issues with the dash cam, such as high voltage or current, which may burn out the memory card. Additional tips for handling frequent memory card damage in dash cams: 1. It is recommended to use high-speed memory cards with a write speed of at least 20MB/s, and regularly format the card (once every 3 months), replacing it with a new one after a year. Additionally, try to lower the resolution while maintaining clarity. 2. Do not randomly insert or remove the TF card while the dash cam is reading or writing data. Always turn off the dash cam before inserting or removing the memory card. Forcibly removing the card can easily damage it, as memory cards do not support hot-swapping. In short, it is best to minimize inserting and removing the memory card from the dash cam. Generally, a memory card used in a dash cam can last several years without any issues.

How much does an 825-20 tire weigh?

Tire weight is not fixed. The 825 tire can bear a load of 15-18 tons, but for safety reasons, it is generally recommended to carry a load of less than 15 tons. Each tire has its own load-bearing capacity, and different truck models may have significant variations in their load-bearing capabilities. It is essential to adhere to the specified load index and avoid overloading. Additional content: Daily tire maintenance methods are as follows: 1. Monthly inspection: Check the air pressure of all tires, including the spare tire, at least once a month when they are cold. 2. Avoid speeding: Do not exceed the reasonable speed required by driving conditions and legal limits (e.g., slow down or avoid obstacles such as rocks or potholes ahead). 3. Regular wheel alignment: Regular wheel alignment and balancing are crucial for ensuring driving safety and achieving optimal mileage. 4. Regular tire rotation: To achieve even wear and extend tire life, rotate the tires approximately every 8,000 to 10,000 kilometers. 5. Prevent tire erosion: Protect tires from sunlight, oil, acid, and hydrocarbon erosion. 6. Develop good habits: Cultivate good driving habits, such as avoiding sudden braking and sharp steering.
