It has been 31 years since the hydraulic bellows appeared in our country's parks. That was the first time people invented the hydraulic bellows. Let's take a look at the development history of the hydraulic bellows.
Water conservancy bellows were called water drains in the past. This material was invented mainly as a device for water conservancy and blasting. It is composed of many materials. A furnace uses several bladders. They are lined up in a row, and then the power of water resources is used to push the sacs, so they are called water rows. The invention of the hydraulic bellows reflected people's ingenuity, because it was the first time that people used the power of nature to transform it into a productive force. At that time, the earliest records of the shape of the hydraulic bellows were divided into different shapes according to the location of the water wheel and the direction of its wheel.
But there is a unique feature. They all work back and forth through several identical parts. It is mainly composed of a shaft, a tie rod and a rope, and they interact with each other. It constitutes a repeated application action. This action can turn the fan on or off. Every time the wheel rotates once, the fan will turn on or off many times. In this way, one use can be exchanged for multiple jobs, which also greatly improves the efficiency of the hydraulic bellows. The main power of the hydraulic bellows is water. At that time, people used the thrust of water to smelt metal.
According to the earliest records, people invented the hydraulic bellows in 31 AD, and later went through a series of improvements. Many inventors have improved this kind of bellows, but it is undeniable that hydraulic bellows have always played a very important role in ancient times. Although they have been improved, they have never been canceled and have always been used. After the development of the hydraulic bellows, people also began to use other resources to improve the bellows. After a long period of changes, there is now a wooden bellows, which is mainly made of wood, but the general structure is It is the same as the hydraulic bellows.
