Thomas? Newcomen is a British engineer and one of the inventors of the steam engine. The atmospheric steam engine he invented is the predecessor of Watt steam engine. Born in 1663 and died in 1729 at the age of 66.
Extended data
Newcomen received only elementary education and worked as a blacksmith when he was young. 17, cooperated with Cali to operate ironware in 1980s, and later * * * developed a steam engine. 1705 obtained the patent right of "condensing the steam entering the lower part of the piston and connecting the piston with a connecting rod to generate motion". Since then, newcomen has continued to improve the steam engine. 17 12 was first made into a practical atmospheric steam engine, which was called newcomen steam engine.
In view of the high cost of animal power drainage in Cornwall tin mine, he and his assistant spent 10 years trying to make a steam pump. The pressure of newcomen machine is not limited by steam pressure. When steam condenses and a vacuum is formed in the cylinder, the piston is pushed down by atmospheric pressure. The first recorded newcomen steam engine was installed near Dudley Fort in Staffordshire in 17 12.
In order to create a vacuum in the cylinder, newcomen invented an internal solidification nozzle and an automatic valve drive device. Using steam equivalent to atmospheric pressure, he kept the material within its working limit. Newcomen's machine has been used in mine drainage for many years, and also used to lift water to drive waterwheels.
Newcomen steam engine has been widely used for more than 60 years, and it is still in use for a long time after Watt perfected the invention of steam engine. Newcomen steam engine was the first practical steam engine. He laid the foundation for the development and perfection of the steam engine later.
