Liugong loader is a heavy machinery and equipment widely used in the field of engineering construction, which is favored by the majority of users for its excellent performance and easy operation. However, for the daily maintenance and maintenance of Liugong loaders, many users may still have some questions, such as how much urea should be added to be appropriate. As an important part of the diesel vehicle exhaust treatment system, urea can effectively reduce nitrogen oxide emissions and protect the environment. For equipment that uses diesel engines such as Liugong loaders, the amount of urea added needs to be determined according to the actual situation of the equipment and the use environment. Generally speaking, the urea addition amount of Liugong loader should be determined according to the urea tank capacity of the equipment and the manufacturer's recommended ratio. When adding urea, excessive or insufficient should be avoided, so as not to affect the normal operation of the equipment and the effect of exhaust gas treatment. In addition, when using Liugong loaders, users should also pay attention to regularly check the working status of the urea tank and urea injection system, and find and deal with possible problems in time to ensure the normal operation and environmental performance of the equipment. In short, for the amount of urea added to the Liugong loader, the user should decide according to the actual situation of the equipment and the manufacturer's recommendation, and pay attention to regular inspection and maintenance of the equipment to ensure its normal operation and environmental performance.
