According to Battery.com.cn, the winter has entered the winter. In this cold season, the maintenance and use of the car has become very important. How to maintain your car in the winter?
First, keep the thermostat working properly
The function of the thermostat is to automatically control the normal water temperature of the engine. At low temperature start, the engine can be heated quickly to reduce cylinder wear. Experiments have shown that if the thermostat is removed, the engine start-up time is extended by 4 to 5 times, and the cylinder wear is increased by 5 to 6 times. Therefore, the practice of arbitrarily removing the thermostat is incorrect.
Second, antifreeze must be changed every two years
If it is a new car, it is generally not necessary to add antifreeze within two years, because all vehicles have been added at the factory. If it is an old car, the high-quality antifreeze has been changed in the previous year, that is, the freezing point, boiling point and anti-corrosion performance of the antifreeze meet the requirements, so there is no need to change this year. The antifreeze is usually valid for two years. The expired antifreeze will cause corrosion of the cylinder and cause serious damage to the engine.
Third, the battery should be supplemented with electrolyte
The battery is most afraid of low temperature, and the battery capacity in a low temperature environment is much lower than that at normal temperature. Before the cold season, the electrolyte of the battery should be replenished, and the terminal of the battery should be cleaned and coated with special grease to ensure reliable starting and prolong battery life. If the vehicle is not used for a few weeks in the open air or cold storage, the battery should be removed and stored in a warmer room to prevent the battery from freezing.
Fourth, the lubricant should be replaced with low temperature
At present, the oil on the market is divided into two types: single-stage and multi-stage. The single-stage oil has a narrow temperature range. One viscosity grade is only applicable to some seasons of the year and cannot be used all year round. If the engine uses lubricating oil as multi-grade oil, it can be used in winter and summer (multi-grade oil: 10W/300E gasoline engine oil, the use range is -20°C-40°C; 15W/300E gasoline engine oil, the use range is -18°C-40°C; 15W/ 400E gasoline engine oil, the use range is -18 °C or more). If your car uses "single-stage" engine oil, it should be replaced with winter low-temperature engine oil.
Five, glass cleaning solution avoid tap water
In the winter, it is very dangerous to use tap water as a glass cleaning solution. Once the temperature is too low, substitutes such as pure water and tap water often freeze and sometimes break the container. Therefore, in the winter, the original pure water and other substitutes must be lighted and replaced with a glass cleaning solution that is not afraid of freezing. If you really want to save, you can use a 5:1 mixed liquid of tap water and antifreeze instead.
The roller line is suitable for conveying goods with a flat bottom. It is mainly composed of transmission roller, frame, support, driving device, etc.
It has the characteristics of large conveying capacity, fast speed, light operation, and can realize multi variety collinear shunt conveying.
