The essential issue of jumping is the strain of the encompassing water wherein we are plunging. Jump down to only 10 meters and the surrounding pressure is twofold what it is on a superficial level. Go down to the 30 meters prescribed to Advanced Open Water jumpers and you are encountering multiple times environmental strain.
This is a colossal variety in pneumatic stress and with simply a slight difference in gaseous tension we would not be able to grow our lungs and suck in air. In this manner, the controller needs to give air at around the strain of the water around us.
In any case, then again, at the surface when you test your air supply you could be sucking in air from a tank which is at a strain of 200 bar – that is multiple times barometrical tension. hookah diving If you somehow managed to inhale air at this tension your lungs would detonate.
So the work of a jumping controller is to give the jumper air at a similar tension as the water around the jumper, for solace and security.
What’s more, this happens in two phases and the names are the large pieces of information to how this work – with a first stage and a second stage controller.
The main stage controller connects to your tank and lessens the pneumatic stress to a tension that is higher than you are probably going to require, while adequately low to be protected inside the high strain tubing that goes between the stages.
The second stage controller takes in the lower (yet excessively high) pressure air and lessens it to the a similar strain as the water around you. This implies that it is completely simple to breath in and truly agreeable.
Be that as it may, how can it do this?
Well in each stage there will be a cylinder or a stomach. Whichever is utilized is presumably not actually important to the jumper, however essentially the high tension air on one side pushes it open, while it is helped on the opposite side to close it when the strain is adequate. Consequently, the valve opens somewhat to permit some air, where raises the tension (or model in the tubing) and when that hits the ideal strain it is helped to close the valve, until the strain is decreased (by the jumper taking in), what begins the cycle moving once more.
The two phases utilize similar essential strategies, with the subsequent stage being opened by the strain of water pressure, which is the thing that changes the air over to a breathable tension.
