Classification of Pumps

Classification of Pumps Points : Classification of Pumps, Types of Pumps On the source of transfer of mechanical energy, pumps can be classify as: 1) Positive displacement pumps: In positive displacement pumps, fluid is sucked and actually displaced by a piston/plunger to reciprocates in a cylinder. The quantity of fluid pump is equal to volume displaced through a piston. A usual exemplar of positive displacement pump is a reciprocating pump.

1. Casing
2. Delivery pipe
3. Shaft
4. Bearings

Advantages and Disadvantages of Centrifugal Pump

Advantages and Disadvantages of Centrifugal Pump Points : Advantages and Disadvantages of centrifugal pump Advantages

1. While present is not drive seal so here is no outflow in pump.
2. Small in volume, space saving & less capital costs.

Uses of Centrifugal Pumps

Uses of Centrifugal Pumps Points : Uses of Centrifugal Pumps Centrifugal pumps are used transport fluids through conversion of rotating kinetic energy to hydrodynamic energy of fluid flow.

Construction of Centrifugal Pump

Construction of Centrifugal Pump Points : Construction of Centrifugal Pump, Impeller, Suction pipe, Suction and delivery pipe, Casing, Gland and shaft Centrifugal pump has following major components:
1. Impeller
2. Suction pipe
3. Suction and delivery pipe

Working of Centrifugal Pump

Working of Centrifugal Pump Points : Working of Centrifugal Pump Water goes into the centrifugal pump during a suction eye. Water is accelerating on vanes (curved) with the velocity steadily increases.

Applications of Centrifugal Pump

Applications of Centrifugal Pump Points : Applications of Centrifugal Pump

1. In thermal plants, pump water to the boilers.

Plunger Pump

Plunger Pump Points : Plunger Pump The plunger type pump lends itself radially to variable delivery, high pressure, and smooth flow and, alone or together with a constant- delivery unit, is an important factor in many hydraulic applications. In the under type of pump the piston, or plunger, which fits closely in its cylinder, draws in the oil as it moves outward and expels the oil as it is pushed back. These pumps have five or more radial cylinders, each of course, with its plunger.

Vane Pump

Vane Pump Points : Vane Pump A vane pump is illustrated. The vane type, pump has advantages in size, weight, quiet running, and long life, and is highly, efficient. the diagrammatic section illustrates the operation of this pump.

Gear Pump

Gear Pump Points : Gear Pump The gear pump is probably the simplest kind of commercial medium-pressure constant delivery pump. This type of pump has been in use for many years for raising and circulating (pumping) various kinds of liquids. Its wide use in the hydraulic transmission of power is due to:

Pumps

Pumps Points : Pumps, Types of Pumps The pump run at constant speed, usually by an electric motor, takes the oil from the supply reservoir and delivers it at sufficient volume and pressure to do the work required.

Reciprocating Pump

Reciprocating Pump Points : Reciprocating Pump, Types of reciprocating pumps, Slip of the pump, Negative Slip of the Pump, Discharge of a reciprocating pump A reciprocating pump, in its simplest form, consists of the following parts as.
1. A cylinder C, in which a piston P works. The movement of the piston is obtained by a connecting rod, which connects the piston and the rotating crank.

Centrifugal pump

Centrifugal pump Points : Centrifugal pump, Types of casings, for the impeller of a centrifugal pump, Volute Casing (Spiral Casing), Vortex Casing, Volute Casing with Guide Blades, Piping System of a Centrifugal Pump, Delivery Pipe A pump in general may be defined as a machine, when driven from some external source lifts water or some other liquid from a lower level to a higher level. Or in other words, a pump may also be defined as a machine, which converts mechanical energy into pressure energy.
