- Azwancloudwan -: How pump works

Salam w b t

Pump is a device to transfer or move fluid or gases by using mechanical mechanism. Pump can be clasified into three major type which are:

Direct lift,

Displacement

Gravity pump

Pumps usually need to consume energy in order to produce the out put (mechanism works). For example to move water from lower area to higher area, this can be done by using an electric motor to move the water from lower region to higher region, we usually can see this in many area including water treatment plant and many more.

However, this time i will focus on one type of pump which are displacement type of pump. This displacement type of pump can be divide into 2 type of pump which are:

Reciprocating positive displacement pumps

Rotary positive displacement pumps

I will focus on Reciprocating positive displacement pumps as its nvolve in my project, this pump again can be classified into four types accourding to its mechanism to transfer fluid and gases. Plunger pump, Diaphragm pump, piston displacement pump, and radial piston pump.

Diaphragm pump

This type of pump, will enable continues flow of fluid without need to continuously move the pump. When we pull up the pump handler, the green layer will move up and create lower pressure inside the box, thus the water outside (the right side of the picture) will flow into the box. when its push down, higher pressure will created inside the box thus will force the fluid to move out from the box.

The valve at the right and left side of the box will make sure the fluid flow in one way direction.

However most of manual pump mechanism is almost the same, there just a bit different between them depends to what mechanism they use. For example Ram pump below, it use gravity mechanism to move the fluid from lower level to higher level.

Same with Nash pump, it use rotary motion to pump water, this mechanism usually used in car in order to cool down the engine. This pump usually located at the timing belt area, and it use the energy transferred from the rotating timing belt to pump the water to all part of the engine.
