The principle of saturation diving is that a diver stays in a high-pressure environment at a certain depth underwater or equivalent to the environmental pressure at the depth, and the neutral mixed gas in the breathing gas gradually dissolves into the human tissue. If the staying time is long enough, the partial pressure of the neutral gas in the human tissue reaches the balance state with the partial pressure of the neutral gas in the breathing gas. In this case, the diver can stay underwater for a long time until the underwater operation task is completed, and then return to the water surface for a one-time inspection. The power of various hydraulic driving devices in the saturation diving system is derived from the hydraulic pump station, and the hydraulic oil tank is a key device of the hydraulic system. The internal hydraulic oil of the hydraulic oil tank is easily affected by the sea conditions to produce violent fluctuation, and factors such as hydraulic oil impact on the tank wall and unstable oil suction port are easily generated, thereby aggravating the wear and fatigue of the inner wall of the oil tank, the oil tank interface and other parts, and the unstable oil supply pressure.
