The use of antifreeze is always a point that many excavators often ignore. Some people even have many misunderstandings about the antifreeze. If the antifreeze solution is not used properly, it may cause damage to some important components and cause significant losses.
The full name of antifreeze should be called antifreeze coolant, that is a coolant with antifreeze. Most of the antifreeze is water based antifreeze using B two Chun, the main ingredient is B two Chun and water, and some additives such as corrosion inhibitor, defoamer, colorant, anti mildew agent, buffer and so on. The mixture of B two Chun and water The freezing point will decrease. When the content of B two Chun is 60%, the minimum freezing point can be reduced to -48.3 C, which can effectively prevent icing.
Xiao Bian today gives you some points for attention on the use of antifreeze.
1, we must choose the regular 名媛直播 of famous brands
A lot of people think that antifreeze can be used, and buy some cheap and inferior 名媛直播 to the machine. Some inferior 名媛直播 are often cut down to reduce the cost. Not only the performance will be discounted, but also the machine is damaged. So the choice of antifreeze must not be cheap, choose the big brand 名媛直播.
2. Choose the right ice point
Ice point is one of the most important performance parameters of a antifreeze solution. At present, the freezing point of the antifreeze is -25 C to -45 C. The freezing point of antifreeze should be about 10 C lower than the lowest temperature in the area where the excavator is located, in order to achieve a better anti freezing effect.
3. Choose the right boiling point
The boiling point is another important performance parameter of antifreeze, which can effectively avoid the "opening" of the engine. Because the boiling point of the liquid decreases with the elevation of the altitude, the high freezing point should be chosen if the area of the excavator is higher.
4. Do not mix with antifreeze
There are different types of antifreeze, even if the main ingredients are the same, the additive formula will be different and should not be mixed, so as not to react, precipitate or produce bubbles. The performance of the antifreeze can be greatly reduced and then the machine is damaged. If the different antifreeze is to be replaced, It is necessary to replace it thoroughly and clean the cooling system at the time of replacement.
5, the antifreeze should be replaced regularly
When the antifreeze is used for a long time, its performance will decline, which will easily lead to poor heat dissipation, which will cause the water tank to "open", and the tank opening to the engine is very clear to each one. The water tank opening is very dangerous, the strict weight will cause the water pipe burst, the antifreeze fluid is splashed, thus damage hair. The replacement period of the general antifreeze is 1-2 years.
6. Antifreeze should be used throughout the year
Some of the excavators think that the anti freezing liquid is antifreeze now, only when it is used in cold weather. In fact, it is not right. It has been mentioned earlier that the effect of antifreeze is not only anti freeze, but also has the effect of improving boiling point and corrosion prevention. Antifreeze is not only used in winter, it should be used in the whole year, so that it can be most possible. Protect the excavator.
7. Pay attention to safety with antifreeze
As the main component of the antifreeze solution two Chun has a certain Du nature, so the addition of antifreeze should try to avoid direct contact with the skin. While B two Chun is not volatile and the evaporation coefficient is far less than water, so it is generally not to worry about the Du property caused by the evaporation of the antifreeze solution.
