ポンプの潤滑装置。[Scope of Claim for Utility Model Registration] (1) In a device for supplying and circulating lubricating water to the bearing case 5 of the vertical shaft pump 1, a water discharge pipe 14 provided with a differential pressure valve 13 is branched into the lubricating water supply circulation line. In addition, the lubricating device for a vertical shaft pump is characterized in that the tip of the water discharge pipe 14 is opened above the impeller chamber 15. (2) The bearing case 5 is provided with a through hole 10 that communicates with the circumferential surface of the main shaft 2, and a recovery pipe 11 for discharging lubricating water is provided in the guide case 7 that holds the bearing case 5, and the guide case 7 is provided with a differential pressure valve. 13 are connected, and the tip of the water discharge pipe 14 is opened from the impeller chamber 15 toward the bearing case 5, thereby controlling the water pressure of the lubricating water supply circulation system of the bearing case 5 and the impeller chamber. The lubricating device for a vertical shaft pump according to claim 1, wherein the differential pressure valve (13) is opened and closed based on a pressure difference between the internal pressure of the valve (15) and the internal pressure of the valve (15).
