(FR) POMPE IMMERGÉE
(JA) 水中ポンプ
Abstract
(EN)
This underwater pump (100) is provided with: a heat exchange chamber (31, 431, 731, 831, 931); a first flow channel (32, 432, 832) which is provided to an outward side of an oil chamber (15) along a radial direction of a drive shaft (10a), through which the heat exchange chamber and a motor-cooling chamber (30) communicate, and which channels a coolant from one to the other of the heat exchange chamber and the motor-cooling chamber; and a second flow channel (33, 433, 833) which is provided to the radially outward side of the oil chamber, through which the heat exchange chamber and the motor-cooling chamber communicate, and which channels the coolant in the opposite direction of the first flow channel.
