In the stern tube sealing device, which has multiple seal rings that face the pressure surface toward the stern tube bearing side, and multiple seal rings that face the pressure surface toward the stern tube bearing side, the stern tube gravity tank and the stern tube gravity tank are located higher than this, closest to the stern tube bearing side. Install a pressure tank for an annular chamber consisting of two seal rings,
A stern tube sealing device characterized in that the respective tanks are connected to each other so as to communicate with each other through a pressure oil supply pipe so that the pressure in the annular chamber is circulated higher than the pressure in the stern tube. (2) The stern tube seals according to claim 1, wherein the oil overflow pipe of the annular chamber pressure tank is connected to the top plate of the stern tube pressure tank. (3) The pressure supply for the annular chamber is branched from the pressure supply pipe of the gravity tank for the stern tube to the annular chamber, and a constant flow rate control type pressure control device is installed at an appropriate position along the way to maintain a constant differential pressure. The stern tube sealing device according to claim 1, characterized in that pressure oil is constantly supplied to the annular chamber.
