SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING w A rupture or burst of an element of a high-pressure aL hydraulic system can be very dangerous. The high velocity streams of oil, which results can damage eyes, pierce skin, and harm other equipment. The author has seen a piece of tubing three feet long and 1.5 inches in diameter thrown whirling for more than fifty feet when a rupture occurred in a 3000 psi line.难燃工作液 Unless fire-resistant fluids are used, hydraulic leaks create B very real fire hazards. Most petroleum based fluids are highly ko: flammable. High temperatures can be generated where a high try velocity stream of oil from a rupture impacts on a flat surface 冲击 Finally, hydraulic power is so compact that developing and controlling fractional horsepower is difficult unless the pressure density is reduced to levels where electrical power is extremely competitiveSCIENCE AND TECHNOLOGY ENGLISH FOR MECHANICAL ENGINEERING A rupture or burst of an element of a high-pressure hydraulic system can be very dangerous.
