Centrifugal water pump the way it's done now

<\A>

The way it is done now

A very effective way to pump any liquid is by use of what is know as a centrifugal pump

Liquid is allowed to flow into the center of the pump and then fill up the pump casing expelling all air in the process

The prime mover motor is then switched on and the blades of the turbine then at high speed forced the liquid outwards.

The liquid is forced into the top outlet and out with great force and pressure into hoses that carry it away.

  1. This pump also suffers from several problems being that if air is allowed to enter the pump casing and the water level falls below the inlet valve no liquid will further be allowed to flow into pump even if the pump continues to operate.

2 The liquid to be moved must be close handy to the pump or not at a depth that will not allow the pump to be primed from the liquid to be pumped before being started..

The above is a typical diagram of the turbine construction although there can be some variation in the design although

the principle remains the same.

It consists of two flat metal circular disks upon one which one is connected to a central driving shaft.

The front disk has a circular centre removed to allows the new liquid entering through the central inlet to allow the

liquid to flow.

In between the two flat disks are placed blades to throw water to the outer reaches of the casing when rotating speed

has been accomplished by means of a electrical or other means of prime mover.

On the back of the pump there is what is know as packing to reduce air flow through the driving shaft into the pump

and decrease efficiency and to prevent fluid escape around the shaft.

A newer Better direction version

 centripetal pump

fig 2

This my idea for a hopefully better version

Basically it is the same ideal but with the turbine blades designed to throw the liquid to the centre , in what is called centripetal action in way similar to the action of nature with tornados ,cyclones and hurricanes

There should not be much difficulty in constructing the pump apart from changing the throw of the blades from what is now done in constructing the type we use today.

Water would not need to fill the entire outer casing to function and only by using a small amount of liquid it would be able to function by picking liquid at bottom casing and then flinging the water into the center of the pump..

It would probably be an excellent idea to have the middle back plate slightly curved on the new turbine to throw the liquid into the central outlet.

As you can see from the above diagram the water inlet is at the bottom of the pump and the output is exited through the centre.

This pump could also be flat mounted as well.

I believe that by working with nature and not against this pump would be more efficient and use less power

than the centrifugal pump that is now used by not having to move as much liquid in an outer increasing circular motion,. but a smaller working liquid capacity into a central circular motion.

The above diagrams show what is common and the differences between the two pump types.
