Question: What Is The Main Function Of Centrifugal Pump?

What are the advantages and disadvantages of centrifugal pump?

Centrifugal Pump – Advantage & DisadvantageSmall in size, space saving & less capital costs.Easy for maintenance.No danger creates if discharge v/v is closed while starting.Deal with large volume.Able to work medium to low head.Able to work medium to low viscous fluid.Mar 20, 2013.

Which pump is more efficient?

Where different pump designs could be used, the centrifugal pump is generally the most economical followed by rotary and reciprocating pumps. Although, positive displacement pumps are generally more efficient than centrifugal pumps, the benefit of higher efficiency tends to be offset by increased maintenance costs.

Which type of pump is different from other?

40. Which type of the pump is different from others in the same group?…Discussion :: Hydraulic Machines – Section 2 (Q. No. 40)[A].Screw pump[B].Gear pump[C].Cam and piston pump[D].Plunger pump

What is the difference between positive displacement pump and centrifugal pump?

The obvious difference between the two is in the way they operate. As displayed above, centrifugal pumps impart velocity to the liquid, resulting in pressure at the outlet. Positive displacement pumps capture confined amounts of liquid and transfers it from the suction to the discharge port.

What are the main parts of centrifugal pump?

The Main parts of Centrifugal Pump are:Impeller. It is a wheel or rotor which is provided with a series of backward curved blades or vanes. … Casing. … Delivery Pipe. … Suction Pipe with Foot Valve and Strainer.

What are the two main categories of pumps?

Pumps are divided into 2 major categories: Dynamic and Positive Displacement (aka Displacement).

What is pump and types?

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.

What are the six major parts of a centrifugal pump?

What are main parts of centrifugal pumps?Impeller. Impeller is a rotor used to increase the kinetic energy of the flow.Casing (Volute). The casing contains the liquid and acts as a pressure containment vessel that directs the flow of liquid in and out of the centrifugal pump.Shaft (Rotor). … Shaft sealing. … Bearings.

What are the types of impeller?

The impeller of a centrifugal pump can be of three basic types:Open impeller. Open impellers have the vanes free on both sides. … Semi-open impeller. The vanes are free on one side and enclosed on the other. … Closed impeller. The vanes are located between the two discs, all in a single casting.

What is difference between compressor and pump?

Sometimes the words “pump” and “compressor” are used interchangeably, but there is a difference: A pump is a machine that moves a fluid (either liquid or gas) from one place to another. A compressor is a machine that squeezes a gas into a smaller volume and (often) pumps it somewhere else at the same time.

Which pump is used in homes?

When it comes to pump types, there are two main types that are pumps for domestic and agricultural water. These two types are further divided into categories, which include: water pump, irrigation pump, centrifugal pump, submersible pumps etc. We use domestic to draw water for our domestic purposes.

What is the main function of pump?

A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system.

What is the principle motion of centrifugal pump?

Generally, a centrifugal pump is based around a casing filled with fluid, usually water. A special unit within the casing exerts fast rotary motion that causes the water to spin, generating centrifugal force that channels it through a discharge outlet.

Which motor is used in centrifugal pump?

induction motorWhat Does a Centrifugal Pump Look Like? Centrifugal pumps come in many shapes, colours and sizes but they typically look something like this. The pumps consist of two main parts, the pump and the motor. The motor is an electrical induction motor which allows us to convert electrical energy into mechanical energy.

Why centrifugal pump is called high discharge pump?

Centrifugal pump is a kinetic device. … So the liquid entering the pump receives kinetic energy from the rotating impeller. The centrifugal action of the impeller accelerates the liquid to a high velocity, transferring mechanical (rotational) energy to the liquid. So it discharges the liquid in high rate.

What is the application of centrifugal pump?

Centrifugal pumps are commonly used for pumping water, solvents, organics, oils, acids, bases and any ‘thin’ liquids in both industrial, agricultural and domestic applications. In fact, there is a design of centrifugal pump suitable for virtually any application involving low viscosity fluids.

What is a major advantage of centrifugal pump?

The biggest advantage of centrifugal pumps is their aforementioned simplicity. They don’t require any valves, or many moving parts. This makes them easy to produce with many different materials. It also allows them to move at high speeds with minimal maintenance.

How many types of centrifugal pumps are there?

fourThere are four main type classifications of centrifugal pump, with the chief distinction of each being the mechanism that drives the reciprocating diaphragm.

What is the common application of multistage centrifugal pump?

Applications for Multistage Centrifugal Pumps Boiler feed. Reverse osmosis. Water supply boosting. Irrigation.

Why do we need different types of pumps?

Some pumps are created to regulate the flow of your drainage. Others are made exclusively for water regulation. There are pumps used to extract oil from the ground, and some pumps are used for filtering liquids. There are even pumps in your car meant to facilitate water cooling and fuel injection.

What does NPSH stand for?

NPSH stands for Net Positive Suction Head and is a measure of the pressure experienced by a fluid on the suction side of a centrifugal pump.
