How to choose matching pumps for a water intake floating boat
A pump is a hydraulic machine that converts the mechanical energy of a prime mover into liquid energy. Its function is to deliver sufficient mechanical energy to the liquid, thereby completing the task of transporting the liquid. The pumps commonly used on ships to transport water or oil are collectively referred to as ship pumps.
Pumps have been widely used in modern ships. For example, fuel pumps, lubrication pumps, and cooling water pumps that serve diesel engines; There are ballast pumps, bilge pumps, fire pumps, etc. that provide safe navigation services for ships; Daily fresh water pumps, sanitary water pumps, etc. for crew and passenger living services. In short, there are numerous types of pumps designed for specific tasks on ships. The main ones are:
(1) Piston pump, commonly used as hand cranked water pump and oil pump, such as bilge water pump;
(2) Rotary pumps (gear pumps, screw pumps, vane pumps, water ring pumps), such as fuel and oil transfer pumps in the engine compartment;
(3) Centrifugal pumps, such as cooling water pumps, fire water pumps, ballast water pumps, and domestic water pumps in the engine room;
(4) Jet pumps are commonly used as bottom water pumps in engine rooms, vacuum pumps in water generators, and salt discharge pumps.
Generally, marine pumps are classified according to their working principles:
1. Positive displacement pump
It utilizes the periodic variation of working volume to transport liquids. There are piston pumps, rotary pumps (gear pumps, screw pumps, vane pumps, water ring pumps), etc. belonging to this type of pump.
2. Wheeled pump
It drives the liquid to rotate at high speed through the working impeller, transferring mechanical energy to the liquid to achieve the purpose of transporting the liquid. There are centrifugal pumps, rotary pumps, axial pumps, etc. belonging to this type of pump.
3. Jet pump
It uses a high-speed jet generated by spraying a working fluid to inject the pumped fluid, and the well undergoes momentum transformation to increase the energy of the pumped liquid, thereby completing the task of transporting the liquid. This type of pump includes water jet pumps, water jet vacuum pumps, air jet pumps, and steam jet pumps.
