| description | The utility model belongs to the technical field of pumps, and particularly relates to a water retaining structure of an electric pump rotating shaft, which comprises a motor rotating shaft with the end extending out of a motor end cover, the motor rotating shaft is rotatably connected onto the motor end cover through a bearing, and a water retaining ring is arranged between the motor rotating shaft positioned on the outer side of the bearing and the motor end cover. An annular lip part is arranged on the inner ring wall of the water retaining ring, an annular lip opening which is arranged outwards is formed between the annular lip part and the inner ring wall of the water retaining ring, and a certain fit clearance exists between the annular lip part and the motor rotating shaft. By means of the micro-clearance fit between the annular lip part of the sealing ring and the motor rotating shaft, the annular lip part does not rub with the motor rotating shaft during normal work so as to avoid consumption of elec |
