What is an air vessel and explain its functions?

35
Air vessels is basically a closedcontainerdesigned to hold gases or fluids at a pressure differentfrom theambient pressure. Air Vessels can theoretically bealmost ofany shape, but general used shapes are sections ofspheres,cylinders, and cones.


Also know, what is an air vessel?

Definition of air vessel. A smallairchamber fixed to the pipeline on the discharge side ofareciprocating pump that acts as a cushion to minimize theshockproduced by the pulsations of the pump.

Also Know, what are the main parts of reciprocating pump? The main components of reciprocating pump areasfollows:
  • Suction Pipe.
  • Suction Valve.
  • Delivery Pipe.
  • Delivery Valve.
  • Cylinder.
  • Piston and Piston Rod.
  • Crank and Connecting Rod.
  • Strainer.

Hereof, what is the use of air vessel in reciprocating pump?

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 togetcontinuous supply of liquid at a uniform rate and to save thepowerrequired to drive the pump.

Why an air vessel is provided at the summit in a Syphon?

Syphon. The highest point of the syphoniscalled the summit. An air vessel is provided atthesummit in order to avoid interruption in theflow.

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.

What is the difference between centrifugal and reciprocating pump?

The main difference between centrifugalandreciprocating pumps is that centrifugal pump is oneofthe rotary pumps which used kinetic energy ofimpellerwhereas reciprocating pump is a positivedisplacement typepump which is forced bypiston.

What is double acting reciprocating pump?

A double acting pump is one which has twosuctionvalves, delivery valves and two suction and delivery pipes.Indouble acting reciprocating pump suction anddeliverystrokes occur together. Due to the reciprocatingaction ofpiston or plunger the water is fed to discharge side andit isemptied to the delivery pipe.

What is separation in reciprocating pump?

The continuous flow of liquid will not exit whichmeansseparation of liquid takes place. The pressure atwhichseparation takes place is called separationpressureand head corresponding to the separation pressure iscalledseparation pressure head.

What is slip in reciprocating pump?

Slip in reciprocating pump is the measureofdifference between theoretical discharge and actual discharge.Andwhen actual discharge delivered by reciprocating pumpismore then theoretical discharge then that difference is calledasNegative Slip.

Does cavitation occur in reciprocating pump?

Cavitation can occur with basically any kindofpump . Cavitation commonly occursinCentrifugal pumps if pump installation isnotproperly done as per the design . But yes it is also observedinReciprocating pumps while there is high velocity suctionordischarge.

Why is it necessary to prime a pump?

Priming industrial pumps is essentialtousing your pump for its intended applications andtomaintain the equipment. Priming is the process ofremovingair from the pump and suction line to permitatmosphericpressure and flooding pressure to cause liquid to flowinto thepump.

What is the positive displacement pump?

Positive displacement pump (PDP) is a typeofpump in which a moving fluid is captured in a cavityandthen discharges that fixed amount of fluid. some ofthesepumps have expanding cavity at the suction side andadecreasing cavity at the discharge side.

What is meant by specific speed?

Specific speed is an index used to predictdesiredpump or turbine performance. i.e. it predicts the generalshape of apumps impeller. It is this impeller's "shape" thatpredicts its flowand head characteristics so that the designer canthen select a pumpor turbine most appropriate for aparticularapplication.

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.

What is the efficiency of reciprocating pump?

Reciprocating pumps have anoverallefficiency that is generally over 85%, sometimes ashigh as90%. The most significant efficiency losses arefrommechanical and volumetric considerations which often amount tojusta few percent. Reciprocating pumps are preferred forlowvolume, high pressure applications.
