Parts2clean Stuttgart (3) Rotary transfer washers

One of my former customers , ask me why I have not talk about his Dürr Ecoclean rotary transfer washing machines in my last post.

Sorry¡¡¡ ,  effectively I supplied when I was in Dür Ecoclean an installation with three excellent rotary transfer washers to clean common rail injection pumps components at 2.000/300 bars that are today working 24h a day without problems.

The installation had a previous stage of high pressure deburr with robot at 2.000 bars followed of a rotary transfer machine with medium pressure spray wash,high pressure wash(300bar) with injection in contact and push pull system, spray , blow-off , vacuum dry . These machines are the top range in the field with central filtration and high pressures power units.The machines were designed and engineered by the Barcelona Dürr Ecoclean office team that was closed in 2007 but I’m not sure that these type of machines are still part of the Dürr Ecoclean catalogue. For this reason a I didn’t mention it in my last post that was dedicated mainly to the Parts2clean presentations.

Another innovative advantage of these machines was the flexibility as easy reconversion for new different parts. The pallet support on the rotary transfer table was of a quick change design. The clamping and High Pressure injection devices were of quick reconversion. The high pressure robot deburr( 2.000 bar operation) had automatic gripper change device with automatic grippers storage .

As maintenance features they had: total index driving system accessibility, total open doors for inside accessibility , quick change of internal components. The Centralised tank , filtration ,medium pressure pumps ,high pressure pumps ,very high pressure pumps , water treatment, and safety filters were installed in a remote area allowing to deserve three or more rotary transfer machines. This layout allowed to have a minimum surface layout on the working areas occupied by the machines itself , keeping the bigger floor surface of the tanks and pumps in the remote area . By other side this layout was an advantage for the maintenance people having all the pumps, valves,and filters in the same area for easy control and follow up..   

Neverless there is another type of Rotary transfer machines , the machines for powertrain components like cylinder blocks and cylinder heads by one side , and another simpler machines for gearboxes and crankshaft .

In my next post we will talk of the cylinder block and cylinder head rotary transfer machines.
