In ancient hydraulic bellows, they used water power to blow air, saving manpower and animal power, and increasing air volume and wind pressure. Do you know who invented the ancient hydraulic bellows? What was his invention process? What is the impact? Today I will briefly tell you about which country invented the ancient hydraulic bellows? What was its invention process?
In AD 31, the Chinese invented the hydraulic bellows. In the "Book of the Later Han Dynasty", it is recorded that the principle of the hydraulic bellows invented by Du Shi, the prefect of Nanyang, was a hydraulic bellows that used water as power to cast iron farm tools. During the Eastern Han Dynasty, in order to solve the problem of insufficient human resources in the iron smelting industry Du Shi, the prefect of Nanyang, invented a blower that combined an eccentric connecting rod with a piston and invented the blower bellows. It drove the leather bellows through a rolling mechanical device, opening and closing it continuously like an accordion. The working method is similar to that of a reciprocating steam engine, but it has the same working principle as a reciprocating steam engine. This blower was called a "drum casting" at the time.
After that, the inventor Du Yu made a lot of improvements in this direction, which has been passed down from generation to generation. The Chinese pioneering use of water conservancy was one of the most significant breakthroughs in energy supply before modern society. . Wang Zhen, an agriculturist of the Yuan Dynasty, did research on the water drainage structure created by Du Shi, and drew a schematic diagram of the water drainage structure in his book "Nongshu". Its working principle is to let the water wash the wooden wheel in the torrent to rotate. Then, the circular motion is changed into linear reciprocating motion through mechanical transmission devices such as axle pull rods, so that the cortical bones can be opened and closed continuously to achieve the purpose of blowing. Soon after the invention of water drainage, it was promoted by people.
Europe did not begin to use blast water drainage until the 13th century AD, which was more than 1,200 years later than China. In the process of large-scale industrial processing, the Chinese's pioneering use of water conservancy was the energy supply for modern society. One of the most significant breakthroughs in history, it was one of the major steps towards the Industrial Revolution.
