How to identify correct HS codes

Engine hydraulic system: maintenance and How to identify correct HS codesmaintenance of important components is an important part of the internal combustion engine, and the hydraulic system of the engine plays a crucial role in the normal operation of the vehicle. It is mainly responsible for converting voltage.The shrinking air becomes the pressure required to supply the traction mechanism, brake and other equipment, and controls the working state of these equipment, so as to ensure the safety, reliability and stability of the vehicle. Therefore, in order to ensure the normal operation of the hydraulic system of the engine and extend its service life, maintenance must be carried out. 1. The working fluid of the high-quality hydraulic oil hydraulic system supports various working procedures of the system. In order to ensure the normal operation of the hydraulic system, high-quality hydraulic oil must be used. Hydraulic oil should meet the standards stipulated by the corresponding countries or regions. It should be a heat-resistant, pressure-resistant, antioxidant, durable, foam-resistant and corrosion-resistant liquid. Otherwise, it may cause leakage, high temperature, oxidation, corrosion and other phenomena in the hydraulic system. Two. Periodic replacement of hydraulic oil. In the hydraulic system, the state of the hydraulic oil has an important impact on the working performance and service life.Therefore, for long-term hydraulic systems, the hydraulic oil must be replaced regularly to ensure the quality of the hydraulic oil and prevent leakage. If the color of the hydraulic oil is turbid or has a strange smell after replacement, the fault should be troubleshooted in time and the corresponding equipment should be replaced or repaired to maintain the normal operation of the hydraulic system. 3. Check the oil filter. The hydraulic oil may be affected by various pollutants during operation, such as sediments, particles, metal shavings, water, etc. These polluted contents must be filtered through the oil filter. Therefore, the oil filter should be replaced regularly and the oil line and its supporting pipelines should be cleaned regularly to keep the hydraulic oil clean and smooth, eliminate the difficulty of liquid flowing, and prevent the failure of the hydraulic system. Four. Check and replace the hydraulic system components. In the hydraulic system, the operation status of each component also directly affects the work efficiency and performance results of the whole system.If oil leakage or wear is found in pipes, valves and other components, these components must be replaced in time to ensure the normal operation of the hydraulic system. In addition to adapting to various pipeline cooperation, valves, motors, punching machines and other important machinery to reduce friction loss and other basic operations during operation, the maintenance of hydraulic system components should be carried out regularly inspected and maintained, problems should be found in time, wear components should be replaced, and the corresponding components and systems should be normal; prevention of zero in actual work. The wear or shedding of parts causes a decline in the performance of the hydraulic system, oil leakage, and even mechanical accidents. 5. The correct operation of the hydraulic system is a large mechanical system composed of various pipes, pumps and valves. If the operation is wrong, it will deform the structure of the whole system and seriously affect the operating efficiency. Therefore, for the use and maintenance of the hydraulic system, the operatorIt must be carried out in strict accordance with relevant regulations and guidelines, and the hydraulic system cannot be changed or disassembled at will to avoid unnecessary failures. Conclusion: The engine hydraulic system is an important part of the engine. Maintaining the hydraulic system is an important measure to ensure the normal operation of the engine. Only by carrying out scientific, regular and comprehensive maintenance of the hydraulic system can we ensure its long-term stable, efficient and safe operation and provide a reliable guarantee for the normal operation of the vehicle.
