jockey pump翻译如何理解？ a jockey pump, or a pressure-maintenance pump, is a small apparatus that works in conjunction with a fire pump as part of a fire-protection sprinkler system. a jockey pump is designed to keep the pressure elevated in a fire-suppression system so that the main fire pump is prevented from running unless absolutely necessary. it consists of a motor, a pump and a controller. when a fire sprinkler is exposed to heat, the pressure in the system drops significantly and a valve opens, releasing water. the main fire pump provides the pressure to the system that creates water flow when this occurs. the jockey pump maintains the normal pressure in the system at an artificially high level. when just one sprinkler is activated, the pressure drops so drastically that the fire pump starts working, and the fire department is alerted. the jockey pump works as part of the fire pump's control system, "riding" on top of the larger pump like a jockey does on a horse. 如楼主说的，是jockey pump消防里面翻译的是管道稳压泵 查看更多
