Centrifugal Pump Vs Reciprocating Pump

Centrifugal Pump Vs Reciprocating Pump



Sr. No.
Centrifugal Pump
Reciprocating Pump
01
Centrifugal pump has smooth and continuous discharge
Due to reciprocating mechanism a Reciprocating pump has fluctuating and pulsating discharge
02
Centrifugal pumps can handle large quantities of liquids
Due to valves and reciprocating mechanism a reciprocating pump can handle less quantity of liquids
03
Centrifugal pumps can lift highly viscous liquids
Due to complex working mechanism of reciprocating pump it can lift only less viscous liquids. It can only lift water and similar liquids.
04
Due to simple construction and absence of extra parts, centrifugal pumps require less floor area.
Due to the presence of air vessels and belt drive, reciprocating pump occupies more floor area.
05
Efficiency of centrifugal pump is high
Efficiency of reciprocating pump is comparatively low
06
Centrifugal pump has silent operation
Reciprocating pump produces noise during operation because of reciprocating parts
07
Centrifugal pumps have low maintenance cost
Reciprocating pumps have comparatively high maintenance cost
08
Centrifugal pumps can operate at high speeds
Reciprocating pumps work at comparatively low speed
09
Due to simple working mechanism and few parts a centrifugal pump has low cost
Due to complex mechanism and more parts a reciprocating pump is expensive
10
Centrifugal pumps have high discharge and low head
Reciprocating pumps have low discharge and high head
11
Centrifugal pump is rotodynamic pump
Reciprocating pump is positive displacement pump
12
Priming is required in centrifugal pumps
Priming is not required in reciprocating pump. They have self-priming.
13
Centrifugal pump uses impeller to impart energy to liquid
Reciprocating pump requires piston to impart energy to liquid
14
Centrifugal pumps are comparatively lighter due to less number of parts.
Reciprocating pumps are comparatively heavier due to more number of parts
15
Centrifugal pumps are easy to install
Reciprocating pumps are relatively difficult to install
16
Centrifugal pumps are generally used for lifting liquids to a tank
Reciprocating pumps are generally used for industrial purposes like Car wash etc.

Centrifugal Pump

Centrifugal Pump "Centrifugal pump  is a hydraulic machine which converts mechanical energy into hydraulic energy (i.e. pressure energy) by the use of centrifugal force acting on the fluid. " A centrifugal pump is the simplest machine which is used in various industries as well as in many daily applications to transfer fluid from lower head to higher head.  Centrifugal pumps are mostly used in chemical industries for easily transfer viscous fluids.   Also, it is less expensive than other pumping devices. In short, it is an excellent machine with efficient working in variety of applications. History of Centrifugal Pump- 1475- Italian engineer Francesco di Giorgio Martini designated mud lifting machine as a centrifugal pump. 1687- Denis Papin developed the first true  centrifugal pump  which was one with straight vanes that was used for drainage.  1851- John Appold, who was a British inventor, developed the first curved vane  centrifugal pump

Vapour Compression Refrigeration System

Image
Vapour Compression Refrigeration System Vapour-compression refrigeration  or  vapor-compression refrigeration system  ( VCRS )  in which the  refrigerant  undergoes  phase changes , is one of the many  refrigeration cycles  and is the most widely used method for  air-conditioning  of buildings and automobiles. Vapor-compression uses a circulating liquid  refrigerant  as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. History:- 1805- The American inventor  Oliver Evans  described a closed vapor-compression refrigeration cycle for the production of ice by ether under vacuum. 1834-   American Great Britain,  Jacob Perkins , built the first working vapor-compression refrigeration system in the world. 1842-  American physician,  John Gorrie  who built a working prototype, but it was a commercial failure. 1850- American engineer  Alexander Twining  took out a British patent for a vapor compress

TURBOFAN ENGINE

TURBOFAN ENGINE The turbofan engine is a combination of the turbo prop and the turbojet engines combining the advantages of both. The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to accelerate air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components.  In the 1950s, Rolls-Royce introduced the first turbofan in the world, namely, RB.80 Conway. Classification 1. According to Fan Location (a) Forward Fan Turbofan Engine (b) AFT Fan Turbofan Engine 2. According to Spools (a) Single Spool Turbofan Engine (b) Double Spool Turbofan Engine (c) Triple Spool Turb
