Marine pumps and their classification

Marine pumps and their classification.Ship pumps are designed to ensure the normal operation of the main machines to meet general ship needs. When pumps are used, liquids or gas media are transported through pipelines inside the vessel, their are received overboard to ship or removed overboard. All pumps used on ships can be classified according to the following signs: by the principle of the constructive action of the field volumetric, blade and jet a ho general body, special !!

Service Plants for Servicing. Auxiliary Mechanisms of the System; Self-Propelled Installation; Independent Volumetric Liquid or Gas with Certain Volumes or Portions. In turn, these pumps are divided into piston and rotary pumps. (disk or rocker), reciprocating in a cylinder; a pump in which a uniformly rotating rotor is placed in the housing, creating a uniform flow of fluid or, lazy gas a, carries the name of a rotary, bladed pumps called pumps, in which the necessary energy is communicated to the pumped liquid, or equals. 110 rotate working blades. The kinetic energy of a jet or gas flowing out of the working nozzle using a high velocity.

Depending on the working substance, the jet pumps are subdivided into water jet pumps (liquid jet pumps, already licensed pumps) and steam jet pumps (ra3 ° jet pumps). Depending on the ability of the pump to switch to supplying the fluid in the opposite direction, they may be a reader. RepeatcouNt. The reverse is made by changing the direction of rotation of the pump drive, as well as by the manipulation of the coupling reversing couplings. The reverse includes volumetric, vortex and axial pumps. General vessel pumps serve the needs of all vessels and are provided in a special compartment or in the narrow areas of the corresponding system. General vessels include: asthma score, sanitary pumps others. Assignment of each of these pumps are defined by . Of the corresponding system, which is serviced by the pump. Special pumps are designed to provide special pumps.

For example, the following: differential banks for supplying seawater to the redline differential tanks – liquid inside the bulk vessel, whether berthed to other vessels; clean! cargo and wastes of washing substances 3 Cargo tanks: washing for supplying hot water to my, fire , sterns); 10 – boiler, uninterrupted operation of these mechanisms branches. These pumps include: fuel, cooling, fuel, oil, nutrient, circulating, condensate, booster, etc. d. Pumps, as a rule, are atomic, t. e. They have their own drive and can operate independently of the work of the mechanisms of devices serviced by them. As an -np pumps change steam engines and tour. Bins, internal propulsion engines, gas turbines, electric motors, pneumatic, hydraulic motors and manual actuators are nominated and also known as “pumps” that do not have an independent drive, but receive movement from the engineered mechanism, for example, mounted on the main engine cooling pumps.
