If the antifreeze should be replaced, it must be replaced in time to avoid unnecessary losses. Antifreeze, the full name is antifreeze coolant. Antifreeze is generally composed of antifreeze, corrosion inhibitor, defoamer, colorant, mildew inhibitor, buffer, etc. In addition to the functions of antifreeze and cooling, it also has the functions of corrosion prevention, scale prevention, rust removal, etc. Because the manufacturers are different, the antifreeze is also different. In addition, the price of antifreeze is also different due to different supply methods and sales channels. So what should we pay attention to when choosing antifreeze for excavators. This article will summarize five aspects of choosing antifreeze for excavators for reference only.
1. Choosing antifreeze in winter depends on the freezing point first
First, look at the freezing point marked by the antifreeze, and choose the antifreeze that is lower than the freezing point that will not freeze under the local temperature conditions. In this way, the engine will not freeze during shutdown and rest.
2. The choice of antifreeze depends on the boiling point
Antifreeze with high boiling point will not be too hot in high-pressure areas. If a good antifreeze is selected, its boiling point is generally high. The boiling point in the high-pressure zone will be reduced, but because it is also higher than the boiling point of water, it can prevent the antifreeze temperature from being too high.
3. Choosing antifreeze depends on whether it is a formal enterprise, and try to choose a big brand
Some small and medium-sized enterprises cut corners in order to reduce costs, and their prices are relatively cheaper. However, these antifreezes do not protect the excavator. Sometimes it will also cause a series of faults such as pipeline blockage and cylinder block corrosion. Therefore, when choosing antifreeze, you must not choose other unknown brands of antifreeze in order to save costs.
4. Try to use the same brand of antifreeze.
Different brands of antifreeze must not be mixed. The production formula of antifreeze of different brands will vary. Mixed use may cause chemical reaction, generate precipitation or bubbles, and reduce the use effect.
5. When using the same brand of antifreeze, pay attention to using the same model of antifreeze.
The formula of antifreeze of different models will also be different. If different types of antifreeze are mixed, the performance of antifreeze will be reduced. Chemical reactions may also occur, resulting in pipeline blockage, cylinder corrosion, water leakage at the water seal of the water pump and the weld, and a series of faults.
