The invention discloses a bearing sealing and protecting device for a liquid pump, which relates to the bearing sealing and protecting device for pumps. The pump body is internally provided with a bearing body, the bearing body is internally provided with a bearing with a main shaft inside. One end of the main shaft is provided with an impeller and the bearing body on the impeller side is provided with a bearing sealing device. The main shaft between the bearing sealing device and the impeller is provided with a liquid block sheet so that a liquid medium entering between the impeller and the bearing sealing device is blocked by the liquid block sheet, thereby, the bearing sealing device is prevented from impact of the liquid medium. When the liquid block sheet rotates with the main shaft, a centrifugal force is generated and negative pressure is generated at the bearing sealing device so that the bearing sealing device is prevented from compact of the liquid medium. The invention has the advantages of simple structure, low manufacturing cost, low power loss and high efficiency and is suitable for various liquid pumps.
Description
technical field [0001] The invention relates to a pump bearing seal protection device, in particular to a liquid pump bearing seal protection device. Background technique [0002] As we know, the existing liquid pump bearing sealing protection device is that a bearing body is arranged in the pump body, a bearing is arranged in the bearing body, a main shaft is arranged in the bearing, an impeller is arranged at one end of the main shaft, and a bearing is arranged on the bearing body on one side of the impeller. Sealing device, in order to prevent the bearing sealing device from being damaged by liquid impact, an auxiliary impeller is arranged between the bearing sealing device and the impeller. Since the auxiliary impeller is arranged between the bearing sealing device and the impeller, this liquid pump bearing seal protection device has complex structure, high manufacturing cost, large power loss and low efficiency. Contents of the invention [0003] The technical proble...
