例句與造句

1. Because these labyrinth seals are non-contact, they do not wear out.
2. Options include a centrifugal liquid ring seal and a non-contacting inert gas purged labyrinth seal that eliminates leakage.
3. Many gas turbine engines, having high rotational speeds, use labyrinth seals due to their lack of friction and long life.
4. A "'labyrinth seal "'is a type of bearing to help prevent the leakage of the oil lubricating the bearing.
5. For labyrinth seals on a rotating shaft, a very small clearance must exist between the tips of the labyrinth threads and the running surface.
6. It's difficult to find labyrinth seals in a sentence. 用labyrinth seals造句挺難的
7. The turbine blades expanded, however, contacting the honeycomb labyrinth seals and allowing the metal to scrape together when the engine overheated, with zero core rotation.
8. Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on other non-rotating shafts.
9. A labyrinth seal may be composed of many grooves that press tightly inside another axle, or inside a hole, so that the fluid has to pass through a long and difficult path to escape.
10. The " teeth " of the labyrinth seal may be on the rotating shaft ( Teeth On Rotor-TOR ) or on the stator ( TOS ), or both, in an interlocking configuration.
11. Labyrinth seals on rotating shafts provide non-contact sealing action by controlling the passage of fluid through a variety of chambers by centrifugal motion, as well as by the formation of controlled fluid vortices.
12. In a report that took more than a year to prepare, the National Transportation Safety Board blamed the May 27, 1993, crash on " the loss of engine power due to failure in the second-stage turbine labyrinth seal ."
13. The labyrinth seal-- a steel ring hidden deep in the engine between spinning turbine blades-- posed a threat known by the engine's manufacturer more than two years before the Life Flight copter crashed, according to federal documents obtained by The Kansas City Star in May.
14. Because liquid-filled labyrinth seals still generate heat due to the viscosity of the seal oil, and because seal oil can contaminate the process fluids, modern high-performance gas turbines use dry gas seals which use spring-loaded rings with an inert gas in between the faces of the rings to provide the seal.
15. The seal provided by a threaded pipe joint depends upon multiple factors : the labyrinth seal created by the threads; a positive seal between the threads created by thread deformation when they are tightened to the proper torque; and sometimes on the presence of a sealing coating, such as thread seal tape or a liquid or paste pipe sealant such as pipe dope.
