摘要:
A fluid pump includes a case including a pump chamber, a reserve tank for storing spare liquid and located in the case but outside the pump chamber and formed so that a space independent of the pump chamber is defined by the reserve tank, a fluid path forming member arranged inside the reserve tank and including a discharge path communicating between a discharge port and the pump chamber, and a communication hole which is formed in a side of the fluid path forming member so as to assume such a position that the communication hole faces an inside of the reserve tank so that the hole communicates between the discharge path and the inside of the reserve tank, the communication hole being sized so that air in the pump chamber is allowed to flow through the hole into the reserve tank.
摘要:
A fluid pump for circulating the cooling liquid to cool the heat-generating part is disclosed. The fluid pump includes a case including a pump chamber for storing a liquid, a suction port and a discharge port provided on the case so as to communicate with the pump chamber, an impeller having pump vanes and rotatably placed in the pump chamber, which suctions a liquid into the pump chamber via the suction port and discharges the liquid out of the pump chamber via the discharge port by rotation, a motor for driving the impeller, installed in the case and having a stator and a rotor to which the impeller is integrally attached for rotating together, a reserve tank for storing spare liquid located and formed in the case but outside the pump chamber, a fluid path forming member arranged inside the reserve tank, including a discharge path communicating between the discharge port and the pump chamber, and a communication hole formed in the fluid path forming member so as to communicate between the discharge path and inside of the reserve tank.

According to one embodiment, a power recovery apparatus used in a desalination apparatus including a reverse osmosis membrane which extracts fresh water from seawater and ejects concentrated water includes a pressure conversion section and a seawater supply section to collect energy of the concentrated water. The pressure conversion section includes a movable part dividing inside of the conversion section into first and second spaces, moves the movable part by causing the first space to receive the concentrated water, and pushes out seawater filled in the second space by the movable part to output the seawater. The seawater supply section merges the seawater from the pressure conversion section with the seawater supplied to the reverse osmosis membrane.
