The inspection of the hydraulic system of ship servos is one of the key links to ensure navigation safety. When conducting this inspection in depth, in addition to routine items, special attention should be paid to the following aspects.

Firstly, the cleanliness of hydraulic oil is of utmost importance in inspection. The cleanliness of hydraulic oil, as the medium for transmitting energy in the system, directly affects the operating efficiency and lifespan of the servo. Therefore, during the inspection process, it should be ensured that the hydraulic oil is free of impurities, sediment, and has a clear color. At the same time, the viscosity of the oil should also meet the specified requirements, as being too viscous or too thin can affect the normal operation of the system.

Secondly, the operational status of the hydraulic pump is also a key focus of inspection. The hydraulic pump is the power source of the hydraulic system, and its operating status directly affects the steering ability and accuracy of the servo. During the inspection process, attention should be paid to observing whether the hydraulic pump is running smoothly and whether there are any abnormal sounds or vibrations. At the same time, it is also necessary to check whether the inlet and outlet ports of the hydraulic pump are well sealed and whether there are any leaks.

In addition, the inspection of hydraulic pipelines and joints cannot be ignored. The hydraulic pipeline is a bridge connecting the hydraulic pump and servo, and its integrity directly affects the normal operation of the hydraulic system. During the inspection process, attention should be paid to observing whether there is wear, aging, or cracking in the pipeline, and whether the joints are tight and well sealed. For problems discovered, they should be replaced or repaired in a timely manner to ensure the safety of the hydraulic system.

In addition, critical components such as safety valves and relief valves in hydraulic systems should also be carefully inspected. These components are important devices for protecting the safety of hydraulic systems. Once a malfunction or failure occurs, it may cause the system pressure to be too high or too low, causing damage to the servo. Therefore, during the inspection process, the sensitivity and reliability of these components should be ensured, and any components that do not meet the requirements should be adjusted or replaced in a timely manner.

Finally, during the inspection process, attention should also be paid to checking the heat dissipation of the hydraulic system. The hydraulic system generates a large amount of heat during operation, and poor heat dissipation can lead to high oil temperature, affecting the normal operation of the system. Therefore, during the inspection process, it is important to ensure the cleanliness and integrity of the radiator, and to promptly identify and address any issues with poor heat dissipation.

In short, the inspection of the hydraulic system of ship servos is a complex and important task that requires careful examination of every link and component. Only by ensuring the integrity and normal operation of the hydraulic system can the navigation safety of the ship be guaranteed.
