Good hydraulic oil for small ship cranes should have the following characteristics:
Good anti-foaming property and air release property
In the air-oil conversion tank, due to the air bubbles mixed in the oil circulating with the oil, not only will the system pressure drop and the lubrication conditions deteriorate, but also abnormal noise and vibration will be generated. In addition, the air bubbles increase the contact area between the oil and the air, accelerating the oxidation of the oil.
