|On this page I explain how I tested my housing and lamps. First I needed a tube. A tube, firm enough to hold the pressure of about 100 meters water. A family member 'found' a tube. The diameter is 31 cm, and it is 90 cm long.|
|On both ends of the tube I milled a groove. And in this groove I put an O-ring|
|On both sides a cap is placed. It takes a lot of force to get it over the O-ring and often the O-ring does not stay on it's place. But with some patience and some dirty words the cap fits on the tube.|
|Off course this is the inlet of the air for getting the
pressure inside the tube. It's a valve from the tube of my bicycle.
But now the big problem is to hold the two caps on the tube, while the pressure inside the tube is increasing. After a simple calculation I was a little worried. The force at 10 bar on the caps is about 7 tons.
I have a big car It's weight is 2 Tons. But 7 tons is something else.
So, sitting on it is not enough.....
|Oh, by the way, this is how I applied the pressure inside. With this test tube, I can test my camera housing and the lamps.|
