STAINLESS STEEL SCREW (II)

After quite a few attempts and difficult adjustment and setting of various machine tools and control devices we were able to manufacture the stainless steel screw, AISI-316.

This is the first and foremost part of the definitive bomb. Together with the sealing disk they represent the core of the mechanism that allows fluid pumping. In the image we show you the screw and the sealing disk "geared" in both its final version and its sintered nylon version, the latter a little unwell after hours of testing.

Watch the video:

In successive posts we will show you how we make the pump body in metallic material and the centrifugal separator that will allow us to separate water from hydrocarbons before pumping.

STAINLESS STEEL SCREW (I)

Once we've verified the design of the screw, we're starting its production in stainless steel.

Due to its geometry and its perfect fitting with the sealing disc it's the most complicated part of the pump.

Nevertheless we're confident of achieving the goal!.

FIRST PROTOTYPE OF OUR PUMP - TEST

Despite the inherent imprecision of the manufacturing technology we were able to operate our pump prototype which was completely made using Selective Laser Sintering of nylon powder.

CONSTRUCTION OF THE FIRST PROTOTYPE OF THE PUMP

Once the idea was developed, to build a skimmer equipped with a Archimedes screw pump but able to separate part of the recovered water, we start manufacturing of the prototype.

Although our final aim is to manufacture a robust pump capable of working with any type of fluid, and being stainless steel the material that responds to such requirements, we decided to make a first prototype using the technique of selective laser sintering of nylon powder.

In this way we built the first pump with a very fragile material, so that if it passed the test we would have guarantees of adjustment and operation to proceed with the very superior investment represented by the metallic prototype.

The technology used responded very well to expectations and not only. We got a prototype that geometrically validated our design but it was also a functional prototype with which we could verify the hydraulic behavour of the pump.
