one reason why a cutter make a tail....

Post  liteglow on Tue Apr 06, 2010 3:58 pm

I had a dream this night lol..
But after some hours (ok minutes) on Youtube watching many cutter test on the laminar jets.
And after some test with my own Solenoid cutters, I discovered something that "maybe" can be a reason why the water goes unlaminar out from the nozzle.

I know from many testing with my nozzles that a tiny tiny shaking in the ground make the water jump and act crazy.
So I think (in my case) that the vibration on my 2 solenoids on each nozzle can make the water unstable during cutting !

I have a solenoid, and a long arm to cut, the arm make vibration on the top of the nozzle, and that is terrible to the water stream!
So I will try to make a small weight on the other end of the long cutter arm, that will reduce the shaking to almost zero.
And i hope\think that maybe this can help the water to be more steady when I cut the water.

There is one proof that maybe can back up this theory, and that is when I cut ON\OFF\ON\OFF fast, the water goes more crazy with a bigger shaking tail.

Well this was only my tip Wink I will find out later if this is only a theory, or can be done in real life also sunny


cheers

It may be tricky to get the alignment right, but another possibility would be to remove the cutter from the laminar jet completely. In my case I am looking to have the jets enclosed with only a small exit hole in a lid, I could mount the cutter to the lid instead of the jet.

Just a thought if indeed it is the vibrations causing the problem.

that is a smart idea, but I dont have the room to remove the cutter from the nozzle.
I dont know that the vibration can make vibration in the water, but I cannot see why it should not.

When I walk in my garden, the laminar jet shake and splash !
