【技术实现步骤摘要】
本技术涉及一种喷蒸汽式船舶推进装置,用在船舶推进场合。
技术介绍
船舶目前还用螺旋桨推进系统,其能量传递过程为;燃料的化学能通过燃烧变为 热能,热能通过发动机变为机械能输出,通过变速器到螺旋桨,变为螺旋桨的机械能,螺 旋桨带动水流动变为水的动能,传递路线长,发动机和螺旋桨的效率很低,只有30%左 右,功率利用率不高,使其船舶速度上不去,因此,如何设计一种新型船舶推进装置,提高 船舶推进速度,是本技术所要解决的问题。
技术实现思路
为了解决上述问题,本技术的目的在于提供了一种一种喷蒸汽式船舶推进装置。为达到上述的目的,本技术采用如下技术方案,—种喷蒸汽式船舶推进装置,包括船体,其特征在于在船体的前端上部设有吸空 气口,在船体的前端下部设有吸水口,锅炉设置于船体内与吸水口相连,蒸汽空气水混合室 设置于船体的后端,蒸汽空气水混合室分别通过空气管、蒸汽管、水管与吸空气口、锅炉、吸 水口相连,在空气管、蒸汽管、水管上分别设有第一电液比例流量控制阀、第二电液比例流 量控制阀、第三电液比例流量控制阀,喷水管、喷蒸汽管设置于蒸汽空气水混合室内并分别 与水管、蒸汽管相连,喷蒸汽口设置于船 ...
