What is use of air vessel in reciprocating pump?

Last Updated: 17th May, 2020

16
The air vessel, in a reciprocating pump,isa cast iron closed chamber having an opening at its base. Thesearefitted to the suction pipe and delivery pipe close to thecylinderof the pump. The vessels are used for thefollowingpurposes: (a) To get continuous supply of liquid at auniformrate.

Accordingly, what is the use of air vessel?

Air vessel. The air vessel is used asanaccumulator to store compressed air, to separatecondensatethrough cooling and to compensate for pressurefluctuations in acompressed air distribution system. Inwater supply systems,air vessels are used as hydrophors andalso as safetycomponents to avoid surge pressure.

Similarly, what is priming in centrifugal pump? Priming is the process in which the impeller ofacentrifugal pump will get fully submerged in liquidwithoutany air trap inside.This is especially required when thereis thefirst startup.But it is advisable to start the pumponlyafter priming.

People also ask, what is the difference between centrifugal pump and reciprocating pump?

The basic and main difference between centrifugalpumpand reciprocating pump is that centrifugal pumpusekinetic energy of impeller so it continuously supply fluid butinreciprocating pump piston sucks the fluid and then pushesitout which does not gives continuous supply.

Does cavitation occur in reciprocating pump?

Cavitation, or the formation of bubbles orvaporcavities in a liquid, results from rapid fluctuations inpressure.Two basic types of cavitation exist in reciprocatingpumps:Suction cavitation can result from obstructed,clogged, orotherwise dysfunctional inlet pipes.

What is the working principle of pump?

The working principle of a centrifugalpumpremains the same, based on the impeller and suction.Workingof the centrifugal motor is pretty simple. Therotation of theimpeller creates a very low pressure at its inlet,called the eye ofthe impeller.

What is meant by reciprocating pump?

A reciprocating pump is a pump which usesabackward and forward movement to move a fluid. In areciprocatingpump, a piston, plunger, or diaphragm movesbackward andforward. A reciprocating pump is one in whichthe liquidfollows the movement of a piston during suction anddeliverystrokes.

Why reciprocating pump is called positive displacement pump?

Positive displacement pumps are calledsoas as they discharge constant amount of fluid under allconditions.second thing is that reciprocating pumps take ina certainamount of fluid and discharge the same. So, a pressurerelief valveis used to protect the pump against overpressurebydiverting pump flow back.

Where is centrifugal pump used?

Centrifugal pumps have numerous applicationsinvarious industries. They are used often in oilrefineriesand power plants. They are also the pump of choiceformunicipal water applications. They are used to movethegeneral water supply from the pressure main in cases where alittleor no suction lift is required.

How do you start a reciprocating pump?

Pump Start-up Procedure
  1. Line up the pump valves.
  2. Ensure that the drain valve is closed.
  3. Open the suction valve.
  4. Open the vent valve to bleed off gases - when liquid comesfromthe vent valve - close it again.
  5. Open the gland-seal valve (if fitted).
  6. Commission the bearing and oil cooling systems (iffitted).

What is pump efficiency?

Pump efficiency is defined as the ratio ofwaterhorsepower output from the pump to the shafthorsepowerinput for the pump. The shaft horsepower isdelivered to thepump from the power unit, which usually isan electric motoror internal combustion engine.

Why is reciprocating pump more efficient?

Efficiency & Performance
In general, a reciprocating pump ismoreefficient than a centrifugal pump.Reciprocatingmachines are generally applied onlow-flow/high-head service.Centrifugal pumps can haveefficiencies as low as 40 percenton low-flow/high-headservice.
