The History Of Diving Suits

- Nov 19, 2018-

Diving suit is the necessary equipment of diving operation, can be regarded as the auxiliary equipment of deep submersible. The diving suit was conceived earlier. In 1617, Kessler designed a water suit and air bag, but it was not actually used. In 1679, the Italian borelli created the world's first diving suit, an improvement on the original helmet diving with only two eyes and a snorkel. His diving suit was a sealed device similar to a modern diving suit, which allows divers to wear to avoid or relieve pressure underwater by keeping the air flowing through an air pump. Undefended divers cannot go deep underwater.

In 1715, lasbridge produced a leather wetsuit, but the harbor suit could only be used in depths of up to 3.5 meters.

In 1797, cliningate designed and produced a diving suit with a tin round hat over his head and a lifejacket made of leather. In 1819, the British invention of the more successful surface air pump diving suit, which was connected to the air pump on the surface of the water, and equipped with a steel helmet, can dive to a depth of 75 meters. In 1857, a Frenchman, carbirol, invented a diving suit made of rubber, which has been improved many times and is still in use today.

In 1865, DE niroli of lucarole combined xibe's helmet with caberol's oaks diving suit to make a freestyle diving suit. The suit has an automatic pressure regulator that changes air pressure with water depth, allowing the diver to move freely underwater without any contact with the surface. At the same time, using this freestyle diving suit, air pressure is no longer necessary for the diver.

In 1924, the U.S. navy developed a helium-oxygen hybrid air supply system, which allowed diving equipment to reach depths of up to 150 meters. In 1943, a French navy major, Jacques cousteau, designed a backpack compressed-oxygen cylinder breathing apparatus, with pressure of 150-200 atmospheres, which allowed divers to dive 40 meters below the surface of the mother ship, freeing them from the restrictions of the mother ship's air supply.
