american hydraulic adapter Brammer UK principle applied Pascal

the hydraulic machine Brief History 1795, J. Brammer UK principle applied Pascal invented the hydraulic machine for packaging, virgin vegetable oil. To the mid-19th century, the British began american hydraulic adapter to hydraulic press for forging, hydraulic press then gradually replaced the large steam hammer. To the 19th century, the United States made 126,000 kN free forging hydraulic press. Since then, the world has manufactured thousands of cattle more than 20 Taiwan 10 levels free forging hydraulic press, which made in China have two sets (see pictures). With the emergence of electric high-pressure pump and improvement of forging hydraulic machine is also to a smaller tonnage of direction. After the 1950s, there have been small, fast forging hydraulic press, can be equivalent to 30 to 50 kN hammer work. 1940s, hydraulic adapters  the German giant made of 180,000 kN forging hydraulic press, then the world has made more than 180,000 kN forging hydraulic machine 18 units, of which one is made in China 300 000 kN.
