7) Motor Pump

MOTOR,PUMP & COUPLING

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work by imparting energy to the fluid. Pumps operate via many energy sources, including manual operation, electricity, engines, or wind power, come in many sizes, from microscopic for use in medical applications to large industrial pumps.

Types of pump :

→ Positive displacement pumps

→ Impulse pumps

→ Velocity pumps

→ Gravity Pumps

→ Steam Pumps

→ Valveless Pumps

HISTORY :

The invention of the pump is accredited to the Mesopotamians around 3000 B.C. Mesopotamia was an ancient empire that was located in what is now modern day Iraq, Iran, Syria and Turkey. The Mesopotamian’s invented a horde of useful things like writing, the wheel, agriculture, wine and the domestication of animals. 

After that, Hellenistic engineers came up with water wheel, which they used for irrigation and as a power source.

MODELED IN CREO AND RENDERED IN KEYSHOT

Centifugal pump – A motor driven pump that creates a suction to pull water. It was invented by Denis Papin at the end of the 17th century.

Savery Pump – In 1698, Thomas Avery designed a pumped that used steam to create a vacuum that could draw water.

Axial-flow – Since the 1940s, this pump has been used as a compressor in jet engines, but it also has applications in the commercial and industrial sector.

Jet pump – This is a variation of the centrifugal pump, but has been modified to suck water from deep wells.

Electromagnetic pump – This type of pump is commonly found in nuclear reactors, because it can move liquid metal (or electrically conductive liquids) and handle very high temperatures. It moves liquid using an electromagnetic force.
