Hello all, I’m working towards building the wtc and ballast tank module for a type 212 submarine.
At the moment I’m focusing on making a working ballast tank, it will work on the high pressure pump plan, IE filling up a tank using a high pressure water pump and emptying it by opening a valve, the built up air pressure should then force the water out.
I’ve got pvc pipe that can take the pressure and have started producing lexan endcaps and the threaded rods to hold them in place but I would appreciate some advice before I move onto the next step.
First of all I’m a little worried about the seal size.
As you can see above and below the wall of the pipe is kinda thin (about 3 mm), the pipe can take the pressure but it gives very little surface area for the rubber between the lexan cap and the pipe to hold an airtight seal.
I’m going to try the method drawn below but would appreciate advice on whether I’m about to spend a lot of time on something that won’t work.
Any sugestions before I push ahead would be much appreciated
Thanks and over to you
