摘要： PROBLEM TO BE SOLVED: To prevent dew condensation in a casing, and to eliminate risk such as short-circuiting by providing a dew condensation box in the casing of an underwater motor via a connecting pipe for connecting the casing with the dew condensation box, and by loading a dehumidifying agent into the dew condensation box. SOLUTION: While an underwater pump motor 1 is operated, water enters the inside of a casing 4 of an underwater motor 2 from a sealing member 10. Then, by operating the underwater motor 2, temperature and pressure inside the casing 4 are increased, and pressure inside a dew condensation box 16 is also increased. Then, the dew condensation box 16 is cooled by surrounding water for allowing the water to condense in the air. A water drop being allowed to condense in the dew condensation box 16 is absorbed by a dehumidifying agent 22, the humidity in the dew condensation box 16 is decreased, and the water in the casing 4 passes through a connection pipe 21 and moves into the dew condensation box 16 for condensing, thus dehumidifying the inside of the casing 4, and hence preventing a fault such as short-circuiting.

摘要： PROBLEM TO BE SOLVED: To reduce leakage of fluid to a low pressure part from a high pressure part, and to self-correct core dislocation of a rotary body and a liner ring by arranging a machining object layer having high machinability on an inner peripheral side slidingly movable surface of the liner ring in a pump liner ring to generate peripheral directional sliding motion in a liner ring part. SOLUTION: An almost cylindrical liner ring 3 is arranged in an orifice part S where a fixed side casing 1 and a rotary body 2 are opposed to each other, and a machining object layer 4 having high machinability is arranged on an inner peripheral surface of the liner ring 3. The liner ring 3 is made of metal such as bronze and stainless steel, and is fixed to the casing 1. While, the machining object layer 4 is made of plastic, and a clearance 5 between the machining object layer 4 and the rotary body 2 is set small. When the rotary body 2 eccentrically contacts with the machining object layer 4, since a contact part of the machining object layer 4 with the rotary body 2 is shaven off by the rotary body 2, leakage of liquid to a low pressure part L from a high pressure part H is reduced by securing a necessary minimum quantity of clearance 5 formed of a slidingly movable surface of the machining object layer 4 and the rotary body 2.
