The pressure of the diving oxygen bottle is 200bar, which is 20Mpa, and it belongs to the category of high-pressure vessels. The volume of diving cylinders ranges from 0.6 liters to 20 liters, usually 8.0 liters to 12 liters (Smilan's 18-liter cylinder is really rare). This capacity refers to the volume of still water, which is the volume of the cylinder when it is filled with water, because water is inelastic and cannot be used anymore.
2. What does diving bottle brushing mean?
It squeezes the plastic bottle to reduce the volume of the bottle and increase the water level. Since the object floats on the water, the water level rises, of course, as the water level rises (the buoyancy force remains unchanged, and the part exposed above the water remains unchanged), that is, the rising tide lifts the boat. A toy that originated from buoyancy is an object contained in a bottle (a diving model) that floats on the surface of the water. When the bottle is tightened, the object sinks, and when it is released, it rises again. The difference is that after the bottle is compressed, the bubbles inside the object are compressed, so that the volume of water discharged from the object decreases, the buoyancy decreases and the object sinks. After letting go, the bubble volume recovers, the buoyancy increases, and it rises to the water surface again. This is different from this question.

You don’t have to wear it. Any level of waterproof watch can prevent water vapor, so it should not be worn in hot water baths or saunas to avoid thermal expansion and contraction causing gaps in the waterproof ring and accelerating aging.
In addition, Longines watches warmly remind you that our watches cannot be used for diving unless the water pressure is specifically stated.
In addition to understanding the waterproof level, watch lovers should also note that the waterproof performance of the watch is not permanent. Aged gaskets or accidental impact on the crown may affect the seal of the watch.
Therefore, we recommend that you send your watch to a Longines authorized service center for waterproof function testing every year.
4. Diving and brushing bottles
The first bottle is the same as the second bottle upstairs: when I was a child at the bottom of Lake Hyrule, I must learn what I must get after diving, otherwise the plot will be unnecessary. continue. The third one: I played chicken with the rancher at Ronglong Ranch. After winning, I took a bottle of milk, drank the milk, and left the bottle. Fourth: Supplement from upstairs: The ten ghosts that need to be caught must be shot with bows and arrows on horseback.

Usually, a compression pump is used for inflation. Pay attention to professional ones, not industrial ones.
It is filled with compressed air and Nitrox diving can only be used after a specialized training course. Generally, diving shops can refill it, or fire stations can also refill it, and some hospitals can also refill it. While inflating, carefully place the cylinder in water to cool.
Use of respirator:
The outside of the respirator is the breathing head, which is actually something similar to a small funnel, made of rubber. When bitten, the funnel opens up in the mouth and is difficult to remove unless you pull it out yourself. There is a knob on one side of the respirator to adjust the air volume, which can be adjusted appropriately according to yourself.
The tank on the diver's back is filled with compressed air instead of oxygen. The diver is not in critical condition and does not require pure oxygen.
Otherwise, they are all compressed air, which is the ordinary air we breathe, just filled into the bottle at high pressure.
When you breathe, breathe normally. Inhale: you consume the gas in the cylinder; exhale: direct vomiting: prominent gas comes out of the mouth on both sides of the breathing head.

Respirators are generally divided into air respirators and oxygen respirators based on design principles.
The working time of an air respirator is generally 30-360 minutes. Depending on the model of the respirator, the maximum limit of the protection time is also different. Generally speaking, the protection time of air respirators is slightly shorter than that of oxygen respirators.
Air respirators are used by firefighters or emergency rescue personnel to safely and effectively carry out fire-fighting, rescue and rescue work in various environments such as smoke, toxic gases, steam or lack of oxygen.
Oxygen respirators are also called isolated compressed oxygen respirators.
The respiratory system is isolated from the outside world, and the instrument and the respiratory system form an internal circulation

7. How to make a diving bottle
Dalian, the best way is to bring a powerful spear gun, preferably one with no resistance underwater, and then when you find fish underwater, it is best to shoot without resistance. method, because I have seen many videos of divers going into the water to catch fish on the TikTok extreme version. They are all equipped with advanced equipment and advanced spear guns. They mainly dive to catch large ocean fish, such as groupers, tuna, and octopus jumps. Seabass etc.

Ordinary diving uses air, advanced diving uses high oxygen, such as 32 oxygen, and technical diving uses helium as air. The ratio is more complicated.
The cylinder stores high-pressure air, not oxygen. The cylinder is equipped with an explosion-proof safety device, so don't worry about it exploding.
However, you should still be careful not to collide with air-filled cylinders. It can be filled with pure oxygen, and then inhaling pure oxygen under high pressure will cause oxygen poisoning.
