As a kind of construction machinery, Liugong loaders are widely used in various construction sites and mines. In the hot summer, the filling of refrigerant is essential for the normal operation of the loader. First of all, we must make it clear that the amount of refrigerant filled by Liugong loader is not fixed, it will be affected by a variety of factors, such as the model of the loader, the type of refrigerant and the current ambient temperature. Therefore, before filling the refrigerant, it is best to consult the relevant manuals of the Liugong loader or consult a professional technician to ensure that the amount of filling is appropriate. In general, the amount of refrigerant filled with a LiuGong loader is determined according to the capacity of its refrigeration system. The larger the capacity of the refrigeration system, the more refrigerant is required. At the same time, different types of refrigerant can also have an impact on the dosing volume. Therefore, when choosing a refrigerant, make sure that it matches the refrigeration system of the loader. In practice, we can judge whether the refrigerant needs to be filled by looking at the pressure gauge of the loader's refrigeration system. If the pressure is found to be too low, then the refrigerant needs to be filled in time. However, it is important not to fill too much, otherwise it may cause the pressure of the refrigeration system to be too high, which will affect the normal operation of the loader. In short, the amount of refrigerant filled by Liugong loader is not fixed, and needs to be determined according to the actual situation. When filling the refrigerant, be sure to pay attention to safety and follow the relevant operating procedures. Only in this way can we ensure the normal operation of the loader and improve the work efficiency.
