Submersible Pump: Working, Types, Applications, & How To …
A submersible pump is a type of pump that is completely submerged in the water. It works by pushing the water toward the surface instead of pulling it. It has a hermetically sealed motor connected to the pump body that helps to push the fluid toward the surface.
Submersible pump - Wikipedia
Electric submersible pumps are multistage centrifugal pumps operating in a vertical position. Liquids, accelerated by the impeller, lose their kinetic energy in the diffuser, where a conversion of kinetic to pressure energy takes place.
Pump-jet - Wikipedia
A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump ...
Veteran Sonarman Explains Why Pump-jets Are Superior To Props ...
2020年1月4日 · Propellers and pump-jets are among the most important and sometimes sensitive components of a submarine class. The highly intricate design art that gives birth to these systems balances efficiency and speed, and even weight, against acoustic signature.
Submarine Secrets: A Deep Dive into Propellers and Pump Jets
2023年8月24日 · Looking to the future, one of the most promising developments in submarine propeller technology is the rim-driven pump jet. This design drives the rotor from the outside, rather than from...

The reciprocating pump. The simplest practical application of this principle is seen in the hand-operated reciprocating pump, a simplified version of which is illustrated in Figure 1-15. Here the inlet and outlet ports in the cylinder, or pump body, are both in the same side of the piston.
